You've never had it so good. You are WEIRD.

If you are reading this you probably live in the Western world, can speak English, have a computer or device of some sort and access to an internet connection.

You are probably WEIRD
Western
Educated
Industrialised
Rich
Democratic

You are a freak, an aberration. Most of the world does not live like this, for most of human history for most people none of this was true.

As in you are rich compared to most of the world, you probably aren't homeless, and democratic as in you get to vote every so often. Educated, you probably finished at least Secondary (High School).

You have access to a clean water supply, antibiotics and can buy all the painkillers you want.

You can say and do what you want within a certain legal framework without fear of being put in prison or arrested.

You have access to more information and knowledge than any other humans in history ever did.

If you are involved in an accident (in the UK) a helicopter will take you to a state of the art medical facility and give you the best treatment in the world for free and may save your life.

You are not trying to grow food to survive on a poor scrap of land owned by a despot you have never met. Your kids are not working in a dangerous mining operation for a dollar a day for 15 hours a day, 7 days a week.

You probably have a gym membership, go to coffee shops, eat out every so often and try to eat healthily some of the time. Depending where you live, you may have access to free healthcare and probably can go for a walk without fearing for your life.

You've never had it so good...

And yet

You are probably stressed and angry, over 70% of work related health and safety issues are stress related.

In the UK, 7.8% of the population meet the criteria for diagnosing anxiety and depression.
1 in 6 adults have a common mental health disorder
19.7% of people aged 16 or over show symptoms of anxiety and depression in 2014.
1 in 3 adults have high blood pressure
More than 25% of the population are obese.
4.5 millions people have diabetes (of which 90% have type 2)
And the number one cause of death of men under 50 is suicide.

Quote from the film Crash. Source: QuoteHD


You may have have a skewed body image and control what you eat to an extreme level because it feels like the only thing you can control. You could look in the mirror and think you are too small or too big, and be wrong in both cases.

You may self medicate with alcohol, class A drugs, prescription drugs, food, shopping or soap operas.

You live in a filter bubble to confirm your world view.

You should be healthy, fit and happy. Everything is in your favour.

And yet...

The cult of the self overtook us, women who are still paranoid about lifting weights and putting on 1 gram of muscle in case they get big and bulky, despite the overwhelming benefits of strength training; standard body image never changes for the masses.

And the young guys taking anabolics who are never stepping on stage or competing in any sport ever but want their biceps to look good in a t-shirt down da club.

We don't have to think about clean water supply or not eating. But as soon as these needs were satisfied something else overtook us, we had time to think and confront ourselves.

You could be unhappy, despite having more than any other humans in history, you could be trapped on a hedonic treadmill.

And yet...

Nearly all the diseases and conditions listed above are preventable, treatable and manegeable with simple interventions.

Prevention.

Its a cliche but the health system is reactive, it waits for you to break before it tries to fix you, mostly with pharmaceutical intervention.

The holy trinity of exercise, nutrition and mindfulness (or call it spiritual connection, or relaxation or spending time in nature, or being in the moment - we know all these things have a powerful effect on emotions, physical health and brain health).

And the thing about most of these things is they are essentially free. Going for a walk in the park is free. Replacing sugary snacks and processed foods with some vegetables is cost neutral. Buying less stuff, spending more time with friends and in nature and less time watching 24 hour news disaster should cost you less and make you more time rich.

Industry fail.

I'm not saying these things are easy. But somehow, in some fashion the fitness industry and leisure industry should be playing its part. Yes joining gyms and going for a swim (unless you go to a lake or the sea) costs money.

And all these pursuits can end up being middle class, white activities. They need to be spread further and wider into the population.

I don't know the answer, I don't have the grand plan. But I do know that the health 'reckoning' is already here.

The media want quick sound bite answers, it's more nuanced than that. They need to grow up and so do we.

And it has to be authentic, its not about paying lip service to schemes and bids for community projects. It has to be more.

People are angry and stressed, but at the wrong things for the wrong reasons in (in my opinion).

The industry has to step up, fuck instagram and the cult of self we helped to make. We need to take it back, it needs to be about health and well being for everybody.

Let me know your thoughts.

Why Run? (Last thoughts).

"This is already a long time ago, I can remember the feelings but I can't still have them. A common prayer for the over-attached: You'll let it go sooner or later, why not do it now?" - Michael Herr, Dispatches.


The eternal question?

'Because it's there' the quintessential mountaineering answer. Doesn't quite get to the heart of it.

The question should be why write, or paint or make films or sing or dance or play a musical instrument. Why create art? Running is the same, or maybe for you it's lifting weights or rock climbing or swimming in a cold lake.





Movement is a natural expression of being human, like art. To such an extent, that if you don't do any of the things listed above then there is something fundamentally missing from your life. It has to be more than being a passive consumer.

A moving koan. The answer is there, but you can't quite grasp it or vocalize it.

You run to escape, you run to go home, you run to remember, you run to forget, you run from the past, you run to ignore the future, you run for now, you run to be like someone else, you run to create your own identity, you run to lose yourself, you run to create your own myth, you run to think, you run to not think, you run because you have to, you run because it's a choice, you run because it's free, you run to be social, you run to be different, you run for your spirit, you run because no one understands you, you run to understand, you run for comradeship, you run to be part of something, you run for no one,  you run to disappear, you run to be alone, you run to feel, your run to not feel, you run to understand pain, you run yourself into the ground, you run to ground yourself, you run to see if you can find your breaking point, you run to be stronger, you run when you are angry, you run when you are sad, you run when you are happy, you run to cope, you run to create memories, your run to erase something and start again.

Some people run for PBs and split times. This seems limited in its scope. Too constrained.

You are compelled to run. In bitter cold, unforgiving heat, brilliant sunshine, drab dull dark wet mornings and endless mediocre grey days. With aching joints and a pounding head. Searching for a meaning. But mainly just running to go through the motions.

But mostly it's prosaic. I once made up the statistic that 1 in 20 workouts are sublime, 1 in 20 are terrible, and 18 in 20 are mediocre/ going through the motions/ get it done. In truth I probably overestimated the number of good workouts, but you are always chasing that golden moment.

The answer as to why you do something is always clearer when that activity is taken away from you. It is always easier to know what you don't want to do with your life than what you do want to do.

For me it was the usual story, running at night and then waking up to 2 litres of IV fluid in a strange room. Be careful, we don't know.

The moment was always coming, it had been encoded in me from birth, I just didn't know it at the time. Years later someone would tell me.

He told me to be careful going West (a true story, crossing time zones can kill). But I had spent my whole life heading West, like some 'Oakie' looking for the promised land of California.

I held my breath for a few years. They told me. And I breathed out.

There would be one last hurrah,, but my heart wasn't in it. I ran into Chamonix as the sun fell behind Mont Blanc. The mountains had kicked my ass. I knew it was over. Another chapter was forming, this one was closed. An unsatisfying unresolved ending. The kind that some people hate to read in fiction books. But life is like that.

There would be no Hardrock, or UTMB, or Badwater or 6 days in Mustang.

There would be no more endless beach run that went on forever, or 10 hours passing like a minute. There would be no more sunrising on the Downs, with a distant sketch of twin windmills, as horses run towards me through the mist, as I run on alone.

And after all that 20 minutes on the road was never going to be enough.

There are other Annapurnas in men's lives, but when Maurice Herzog wrote that, he had made it to the top of Annapurna, if he hadn't, he would have kept going back like all the other obsessed mad men and 'Conquistadors of the useless'.

Like telling Picasso he could only ever use an Etcha A Sketch (to be fair Picasso would have probably done pretty well with an Etch A Sketch) or telling Monet he could only use a paint by numbers. The 5k park run was never going to be enough, so I let it go. It's not that Etcha A Sketch, paint by numbers and 5ks are bad or worth less, you just can't go back.

The dopamine rush of equipment. Seeing the rucksacks, hydration options, trainers and GPS watches. Like the paraphernalia of drug addicts. It's best to go cold turkey.

Just another story about lost love. They all are. Me and the trail were never going to be just friends, it was more complicated than that.

Who the hell wants to take the road most taken?

Like a retired punch drunk boxer who keeps making ill advised comebacks trying to recapture the glory days and getting beaten to a pulp. It's best not to step into the ring again.

If you haven't got the answer to the question after running 100 miles, then you wont answer it, so you might as well let it go and move on.

Sense memory, the way the cool air hits on a clear morning in the forest near where I live (where there isn't actually a forest, another mystery), a faint odour of earth and passing rainstorm. Molecules of pine vapor. And it all comes rushing back. A Proustian Madeleine moment of memory recall.

A forest where there is no forest.


Songs from my youth resonate, fragments remembered 'Is a dream a lie if it don't come true, or is it something worse..' Yes, probably.
'You get used to anything, sooner or later it becomes your life'. Yes, may be you do.

You carry it with you.

Why run? All I can say is...

Sundown.
       Twin Lakes.
                I kept running.

Do you need to deadlift?

More specifically do you need to deadlift with a barbell from the floor?

If you are a powerlifter, yes, you have to.

Everyone else... probably not.

The height of the deadlift is arbitrary, based on the size of an Olympic plate, it is not based on your height, limb length, mobility or spine.

If you are 5 foot tall with long arms it's not that far away, if you're 6'5" it's a long way down.

What about the sumo deadlift I hear you say? Yes, there is less shear force on the spine (you are not bending over so much), but it still depends on your hip architecture, your back may be more upright and it may be more leg dominant, but you still need to be able to pick the bar up from near the floor. I know now a hybrid position of half sumo and half conventional is more fashionable, so it might be worth giving this a go.

Ed Coan: If you look this feel free to keep deadlifting.


Don't get me wrong the hip hinge is a fundamental movement.

But so many people can't lift from the floor without losing a good neutral spine position. Or they end up using a mixed grip or straps chasing a PB and the next thing you know, something snaps and it's not the cheap straps. Getting the bar up anyway possible becomes a fixation for them and can end in disaster.

Yes, you need to be able to hinge from the hips to use the glutes and protect the back when picking all sorts of things up.

One of the best ways to spare the spine when picking an object up is the so called 'golfers lift' which is essentially a 1 leg RDL, hinging on one leg and using the other as a cantilever. But I wouldn't be doing this with 200kg. No one ever chased a golfers lift PB.

Why are you deadlifting?

Is it to chase arbitrary weight goals, hit 100kg, 200kg, 300kg+. If you enjoy the process then fine.

If you are doing it to get 'stronger', then stronger for what? For more deadlifting?

Or for a sport? Then I would contend there are better options like rack pulls, suitcase deadlifts into farmers carrys.

The farmers carry will get your quadratus lumborum activating in the back, abductor activation,  obliques, grip work and more, add in some distance and you've got endurance as well; all with much less chance of technical breakdown under a very heavy load.

If it is to increase muscle mass, then again there may be better options, such as rack pulls, RDL, cable pull throughs, kb swing.

Plus all the single leg work options such as single leg RDL.  In the single leg version, in my experience, people can normally keep a much better back position and it is more self limiting as an exercise.

What benefit is there lifting the barbell from the floor, or in some cases from a deficit by lifting by standing on a small box or step such as the snatch grip deadlift; that can't be garnered from the lifting the bar slightly higher?

For most people a rack deadlift would be a better option. This takes out the most problematic part of the lift for most people. And means they can still focus on hip hinging, gripping the bar, irradiating tension through the body and keep a better back position. The same with a snatch grip from the rack or hang position. Add in a power shrug or high pull to the movement and you've got a good overall athletic move.

Now, I'm not talking about guys who load up the bar and set the rack about 1 inch below lockout, put straps on and then do a 1 inch 400kg deadlift.

The trap bar deadlift is a much easier lift for most people, it is much more intuitive and how people pick things up. However, the biggest issue with the trap bar is how awkward it is to move around and load up. Trap bars normally weigh more than the standard Olympic bar, typically 30kg plus. People tend to put their back in a poor position trying to move the thing and load it up, not during the actual lift.

When I injured my back, the Jefferson lift felt fine, it never aggravated my back. I couldn't lift as much as conventional deadlift, but it felt as hard and demanding but safer. For a good video and explanation of the Jefferson have a look at this link.

The only downside of the Jefferson, is everyone is going to think you are one of those guys doing a crazy exercise for the sake of it.

Take home points:


  • If you like deadlifting, then keep on doing it, and if you are a powerlifter then you need to. Nothing I say would stop you anyway.
  • But be  a stickler for form in the gym, there should be no variation in the reps. Leave the 'whatever it takes' rep for competition.
  • Ask yourself why you are chasing numbers, are big numbers on the bar carrying over into your other goals such as improved sport performance, hypertrophy or overall strength.
  • Try rack deadlifts, the bar might only have to be slightly higher than the standard height for you to keep  better form
  • For sports performance try suitcase deadlifts, farmers walks and long jumps (broad jumps).
  • For hip hinging and hypertrophy try single leg deadlifts with dumbbells or kettlebells, RDLs, cable pull throughs, a whole range of machines, kettlebell swings and more.
  • If you've had back issues which tend to show themselves when you start to load up on the conventional deadlift but you still want to deadlift, then try the Jefferson deadlift.
Let me know your thoughts, is the deadlift a staple of your programme? Do you lift heavy all the time, or use deload periods, speed/ dynamic variations. Do you switch up the style you use? Do you think you need the deadlift for strength, hypetrophy and sport performance.

Do you need to squat?

More specifically do you need to back squat with a barbell on your back?

If you are competing in powerlifting, then the answer is yes.

If you are competing in weightlifting, the answer is probably yes.

For everyone else I'm not so sure.

The squat pattern is fundamental..

Now, don't get me wrong, I think the squat pattern is fundamental. Young babies do it naturally, and adults need it to get out of a chair.

In fact, one of the things I see with many back pain sufferers is they get out of a chair using their back, and spinal flexion, and don't use their hips or knees properly at all. It's the same with stroke patients I see, and some very elderly people, they can't get out a chair. This is sometimes because of weakness, but also an exacerbating factor is they normally have too narrow a stance, have valgus collapse and don't use any type of hip hinge at all. Many manage to get out a chair with some simple cues, without actually getting any stronger per se.

Recently, I haven't really programmed back squats for anyone.

It's not as if I never did them, I've done high rep squats in the past, 21 days of squats myself, squatted maximum, done high bar, low bar, safety bar, cambered bar, box squats. But now, if I do a squat it is invariably a front squat with a barbell or 2 kettlebells.

Squats ahoy.

There was a time when the back squat was rare. Now thanks to most gyms having power racks and the influence of a few key people, back squatting is very popular from young girls to rugby players and beyond.

Also increasingly popular is back squatting in Olympic weightlifting shoes. These allow people to go lower, in a sense give them false mobility. This has resulted in a rush of people complaining about their knees hurting squatting. The standard answer is the Dan John one, squats don't hurt your knees, what you are doing does...

However, I know from personal experience and from friends of mine continuous squatting in lifting shoes does hurt your knees and cause excruciating pain if you are squatting regularly. And as soon as you take the shoes off, the knee pain spontaneously resolves.

Now, don't get me wrong, I have lifting shoes, and for front squats, cleans and snatches I would use them if I was going heavy and really wanted focus on these moves and the sport. But as I generally don't, if I do a power clean or front squat I do them in my normal shoes I train in (inov8 F-lites).

Why are you back squatting?

There is the issue of why you are back squatting.

If you are doing it for leg development, I think there are better options. Front squats target the quads more and with less spinal loading and less chance of technique breakdown.

I know some people can't do the front squat grip, in which case I would do a goblet squat with a dumbbell or kettlebell rack squats. I am not a big fan of the classic bodybuilding front squat with the arms crossed over, it looks like an accident waiting to happen.

Alternatively, a Bulgarian split squat (rear foot elevated squat), or the leg press using one leg at a time (I prefer the one leg version as it's easier on the lower back, and stops the dominant leg taking over).

I know there is a school of thought that bilateral leg work, and specifically 5x5 on squats is all you really need to do. I respectfully disagree.

The hack squat seems to have become fashionable recently, possibly because it can be loaded up and is technically easier than a squat. To me it still seems to cause the same compression issues, and is overrated. It also seems to be exactly the same movement pattern as the Smith machine squat (legs forward, back vertical) that we used to do back in the day when gyms didn't have power racks.

For the posterior chain, take your pick from RDLs, single leg RDLs, hip thrusts, glute bridges, glute ham raise machine, Nordic hamstring curls, and various leg curl machines.

For most people I think there are better ways of targeting the legs.

For athletic purposes I think some unilateral leg work is a must, and something as simple as a bodyweight jump squat or lung jump (broad jump) would be more effective.

Athletically, I would say the prowler push and sled drag have more carry over to the field with less spine compression, less coaching and less risk of losing form and powering through anyway.

Technical breakdown.

Some of the issues with squatting I have are to do with trying to fit all people into the same box. Same stance, same depth.

If you have what Stuart McGill calls the 'Celtic hip', you are going to probably need a wider stance and squat above parallel - and no amount of mobility work is going to change this.

The shrill call of everyone having to go 'ass to grass' seems to have lessened recently.

If you have a much shallower hip socket, Eastern European hip, your squat will look text book. Very few people look like this in the gym. However, there is still no excuse to be bouncing out of the bottom with the sacrum tucking under unless there is a gold medal at stake.

Dave Draper squatting. If you look like this then carry on. Source: everyone on the Internet who thinks this is Tom Platz


If you have nice ovoid shape discs in your back (again see Stuart McGills work), you can probably take the compression in the spine. If you have a much more slender spine, there is more chance of buckling and an end plate fracture with continuous heavy loading (I'm not saying this will happen, but look at the risk reward).

Then we have too much lordosis, too much arch in the back, I see this with quite a few women squatting. They can be quite stiff in the hips and compensate with the back.

Then there are people with limited shoulder mobility, normally guys, and even getting the bar onto the back is problematic and causes shoulder issues before they even start.

Then there are the people who shift to one side under load, twisting and having one leg stronger than the other. These aren't  necessary bad things, its just the way this person is built. But I don't think bilateral back squatting is going to make there leg strength more equal or change their movement for the better.

To paraphrase Gray Cook, people are loading up their dysfunction for no other reason than they think they need to back squat. They then breakdown and they could have got the same results with a different exercise.

Now I know many of these issues can be fixed by coaching, cuing, using  a box, adjusting peoples stance and depth, using different bars on their back. However, most clients don't come to you to get better at back squatting, they come to you to lose weight, or get stronger or more toned. And in my experience for many of these people, save yourself time and do something else instead that gets them the results they want.

Squat patterns that I use.

Sit to stand to box or chair - the fundamental pattern for rehab clients.

TRX supported squat and deep squat for lats with exhale at the bottom - good for turning off the lats, breathing and giving people the confidence to squat lower.

Goblet squat - nearly every session I do includes this, use a dumbbell or kettlebell.

1 kettlebell rack squat - asymmetric loading for core and more.

2 kettlebell rack squat - one of my favourites for added anterior core activation and a great leg workout.

Barbell front squat if someone can get in this position, if they can't I wouldn't bother with various bodybuilding versions I would do kettlebell rack squats instead.

Bodyweight jump squat for athletic development if needed.

--------

Is the barbell back squat bad? No. Do I use it with most of my clients anymore. No.

Let me know what you think.

Forming new habits. Part 5: Choice.

For part 2, 3 and 4 go here, here and here

Why do you make the choices you make?

Why do some people choose to exercise and eat healthily and others don't.

Every day you are exposed to an enormous amount of information. According to Plassman et al (2012)

"Each second we are exposed to an estimated 11 millions bits of information that reach us through our senses, yet humans are capable of processing only around 50 bits of that information."
Think about that for a second (and if you did, 11 millions bits of information were just missed by you). Your brain filters information so it doesn't get overwhelmed.

Your brain and body use autopilot, short cuts and what Daniel Kahneman calls fast thinking all the time (see part 2 for a description of this system 1). Without it you would probably be paralyzed by indecision everyday. You get up, shower, clean your teeth, get to work without much thought. These become habitual activities. When you travel somewhere new, have you noticed how much you have to concentrate, in the car you have to turn the radio off and really focus on the sat nav and the road, not the same as when you do your daily commute.

Certain decisions have been taken out of your hands from an early age. Where you were born and your parents preferences have already determined the language you speak, the foods you culturally like, the school you went to, many of the hobbies and past times you chose. You may not even be aware of other choices, you can't miss a food you've never had or are not even aware of. And that job you drifted into after school or university, it may have not been your top choice, but possibly, only years later you realize you want to do something else.

This fast system of shortcuts is useful. Going out for a coffee on your lunch break if you live in a big city could be overwhelming. If you were really to evaluate all the options you would have to go to every coffee shop, try every different type of coffee, weigh up the price and distance from your work places and then make a decision (okay, I may have actually done this). Whereas, most people will intuitively go to the same coffee shop and order the same drink.

If the choice is limited it is easier, only one coffee shop, you go there. Only one gym, you join that one. In fact, it has been shown the more choice people are given the harder they find it to make a choice. In one study, given  a choice between two different types of jam, you pick one quite easily. Given the choice of 10 or 20, then what? You are frozen with indecision over a pot of jam.

Extrapolate that to big life decisions like choosing a career or partner, the number of variables is overwhelming. This is where the shortcut, intuitive system, works best.

Dijksterhuis et al (2006, good luck pronouncing that name by the way) state that conscious thought works best when you are making simple choices like "buying towels or an oven mitt" but more complex matters like choosing a house, or car (or life partner) should be left to unconscious thought. What they call "deliberation without attention". Your unconscious mind has much bigger processing power and your conscious mind finds it hard to focus on more than one thing at a time.

When buying a car, studies have shown people make better decisions when they don't consciously think about all the variables.

Dijksterhuis et al (2006) got people to choose a car based on 4 attributes or 12 attributes (safety, mileage etc). They were given 4 minutes to think about their choice, or 4 minutes distracted by doing anagrams. The people who were distracted doing anagrams and therefore used their unconscious mind, made a much better choice when choosing a car when they had to think about 12 attributes.

We make emotionally driven choices all the time. We are not even aware we are making them.

Companies and marketers know you can be influenced, so they exploit these systems.

You are influenced by marketing even when you think you are not.

Think about all the advertising you are exposed to. Does it influence you? Of course not, you are smarter than that. Or may be not.

In a study by Bagdziunaite (2014) three group of people were shown commercials before going in to a store to buy paint.
Group 1 - random commercials
Group 2 - random commercials plus adverts for brand A paint
Group 3 - random commercials plus longer adverts for brand A paint

They were then told to go and buy some paint for redecorating.
Group 1 - 78% chose brand A
Group 2 - 94% chose brand A
Group 3 - 100% chose brand A!!

Group 2 and 3 also spent more time looking at brand A on the shelf. And guess what, 23 out of 25 participants did not perceive the link between exposure to advertising and their purchase.

And ALL of the participants who saw brand A remembered it, but reported it did not affect their choice!

Now think about the adverts you are exposed to, the filter bubble you live in, the shops you go to, the choices you make. In the supermarket, trying to make healthy choices...

Plassman et al (2012) state
"At fast decision speeds a significant number of food choices were biased towards the food items with bright packaging, even when subjects preferred the taste of alternative food options." 
In fact, given less than 1 second you will choose the most salient thing, given a second or more you will choose your preference,

Now given that most foods that are brightly packaged are processed, and if someone has been eating unhealthy for a while and has certain in built preferences, what choices do you think they are going to make?

You will choose from the menu on offer. 

There is a myth that humans will make rational economic choices. Choosing between an apple and a snickers, you choose the one that costs the least or has the most benefit for you. Except in the Western world the cost difference between these purchases is irrelevant.

The value you assign to anything is subjective. For example, chocolate or strawberry ice cream have no intrinsic value, you make a decision which one you prefer (Padoa-Schioppa, 2011). And if one is not available, it doesn't figure in your decision making process.

Or put it another way, do you want a £1000 or a glass of water? The answer is obvious unless you just came out of the desert, you're dying of thirst and someone offers you that choice. Context matters.

The orbital frontal cortex (OFC) front part of your brain has neurons that are particularly active when you prefer one option. They are not sensitive to the menu, but decide based on what is on offer.

For example, Padoa-Schioppa (2007) offered monkeys* raisins or apple slices. Monkeys prefer raisins, but eventually when the monkeys are offered 3 times as many apple slices to raisins they switch to choosing the apple. The OFC neurons then start to fire off more, as they react to one decision that is clearly better than the other.

This also happened when the monkeys had to choose between drops of water and kool aid. The monkey prefer water, until they were offer 6 times as many drops of kool aid to water, and then they switched and chose the kool aid and the OFC part of the brain was more active and helped make this decision. They even did this when they were given 2 food options they had never encountered before, they would make a choice and then switch if significant quantity of their less preferred option was given.

What does this mean for you? It means you can switch your own choices.

I read somewhere that you should crowd your diet with healthy choices. If you eat enough vegetables and whole foods, you will 'crowd out' the unhealthy options. (Sorry, I can't remember where I read this, if this is your idea, let me know, and I will credit you)!

Eventually, you brain will choose from the menu you on offer.  You can control the menu and the quantity of the menu as well.

You go to a petrol station...

How does this all work in practice. A classic way people lose track of their diet.

They have gone to a petrol station to fill up the car. This is a top down conscious decision.

But then in the shop they are confronted by chocolate bars and crisps. All brightly coloured. There are no healthy options on offer, you're hungry (you've just left the gym) and you are not carrying any healthy snacks.

Before you know it you are making a bottoms up decision, you had no intention of buying chocolate. But it's there, and the menu on offer is chocolate or more chocolate. Before you know it you are in your car eating a snickers and your diet has been derailed before you've even had time to think. The pleasure centres in your brain are firing off and you go home and wonder what happened.

Why you will be fooled by expensive wine and works of art.

The orbital frontal cortex helps you make choices. And the medial part of it (mOFC) is believed to activate more when you experience pleasantness.

In one study by Plassman et al(2008) they measured the activation of peoples brain in an fMRI scanner while they were given wine of different value, they were told the wine cost $90 or $5 o $10. Of course, there was no difference in the wines but people experienced more activation in the pleasantness areas of the brain when they thought they were drinking the more expensive wine.

The perceived price did not change the activation of the primary taste centre of the brain, but the expectation of how good it was meant to be changed the activation in the pleasantness centre of the brain.

(And as a side note: Wine experts can't even tell the difference between red and white wine when blind folded!).

In another study people valued works of art more and had more engagement in the mOFC when they thought they were painted by an expert rather than a novice. Of course, none were painted by an expert.

If I told you I painted this you'd give me £1 for it. But if I told you Jackson Pollock did, you might be willing to pay way more.


This has led to the idea of "placebo marketing".

Why do people spend £200 more on a computer because it has an apple on it? (like the one I'm typing this on).

In the world of fitness and nutrition you could use this effect to your advantage. If you spend £80 a month on a gym membership or get the platinum super duper personal training package with the best trainer in town, you may well perceive that your results will be superior to the £20 a month gym and the free programme you got given.

You may possibly work harder and just have more belief in the product.

In terms of nutrition, the super detox juice you bought for £6 a glass may seem more beneficial than the apple and bag of spinach you bought in the supermarket.

This may also explain why people see famous online coaches, posting up pictures of clients, and testimonials. You may automatically perceive this person as an expert and expect to get results when you buy their programme or online product.

Even if objectively the expensive options are no better than the cheap options.

Where does this leave us?

So you know your brain is now making decisions on autopilot all the time and whether you like it or not marketing can influence you.

Here are a few take home points relating to health and fitness


  • Make it as easy as possible for your brain to make the right decision. Reduces the cognitive load. This is why Steve Jobs wore the same outfit everyday. Put your gym gear in your bag ready to go in the morning. I once heard someone give the advice of sleeping in your gym kit and then getting up and going, it might be going too far, but you get the idea.
  • Put the gym session or class on your schedule, it becomes an autopilot activity.
  • Not sure what to do in the gym, get a plan/programme that is not too complex and stick to it. Again it will take another decision out of your hands.
  • You will choose from the menu on offer. Fill your cupboards with healthy options, crowd out the unhealthy.
  • Be prepared when out and about. Take your own snacks with you, a box of nuts in the car may stop you buying chocolate in the garage. Also prepare your own lunches.
  • Avoid the office on cake day!
  • Trying to give up fizzy drinks/soda? Try drinking 6 glasses of water when you feel the need for a soda. (I'm serious, give it a go, but don't over hydrate).
  • You can change your preferences with regards to food, they are subjective and you can switch them.
  • Take a shopping list to the supermarket. Take your time, when tempted by bright colours and packaging. Pause, take a breath and stick to the list.
  • You may think the more expensive product is better, it may not be.
  • OR if you are a personal trainer or gym, people may perceive your product as better if you charge more and be more willing to listen to you if they perceive you as an expert. (Testimonials, qualifications etc can help with this).
  • Sometimes your brain will make the right decision without you thinking about it, especially if it is a complex decision.
  • Beware of placebo marketing and living in a filter bubble.
  • Your environment and the people you surround yourself with will influence your choices. The old adage that you are the sum of the 5 people you spend most time with is true. Expand that to environmental influences, the websites you visit, the TV shows you watch, the books you read.
  • Buy cheap wine and tell people it's expensive. They wont know any different!

Experiments in Hypertrophy: Part 3 - Reps, Rest and Tempo.

In parts 1 and 2 I covered the best training splits and how many exercises to do. For part 1 and part 2 go here and here.

Note: if you don't want to read the whole post, skip to the bullet points at the end which tell you everything you need to know.

Rep Ranges.

The classic hypertrophy rep range is 8-12. Most guys (and women) training for mass spend the majority of their time in this rep range, with the occasional venture into the strength range of 6 or less during winter bulking phase and into the higher 12-15 'endurance' range when getting ready for summer.

But some athletes appear to increase muscle mass and never go near the 8-12 range. For example, Olympic weightlifters are normally way below this and Crossfitters are normally near maximal or doing some crazy high rep range (55 rep deadlifts anyone?).

So what does the research show. Previously in part 2 I outlined Brad Schoenfelds research where one group did 7x3 and another 3x10 and basically got the same results and improved muscle hypertrophy. However, the 7x3 workout took more than twice as long as the 3x10 and the strength group started to break down and complain of overtraining.

In a follow up study Schoenfeld et al (2016) did something interesting, they compared 3 sets of 2-4 reps with 3 sets of 8-12 in experienced lifters. This meant there wasn't a big difference in volume, 3 sets of 2-4 is achievable. Both groups did 7 exercises to failure in the prescribed rep range with 2 minutes rest between sets. They measured the cross sectional area of the triceps, biceps and lateral thigh before and after the 8 week trial. There was an increase in biceps in both groups but not much difference, an increase in triceps in both groups but not much difference and an increase in lateral thigh in both groups but a statistical significant difference between groups, with the 8-12 rep range working best. So even though the study shows moderate 8-12 rep range to be better, both schemes increased cross sectional area and when you look at the raw data it is really not that much different. The authors put some of the strength groups success down to the novelty of changing the programme, as most participants were training 8-12 before the trial. Unsurprisingly the group training heavy increased their squat 1RM the most as well.

But what about high reps?

Two studies stand out showing very high rep ranges, Schoenfeld et al (2015) compared 3 sets of 8-12 reps with 3 sets of 25-35 reps, using 7 exercises, 3 times a week.

Both rep schemes significantly increased the cross sectional area of the biceps, triceps and quads. There was no significant difference between the groups. None of the high rep group had lifted with this many repetitions before despite being experienced lifters. But they were experienced, this was not 'newbie' gains. It could be they were targeting the type I endurance fibres, whereas normally they would be targeting the same fibres all the time - the type II ones.

But don't be fooled, very high reps to failure is taxing, as Schoenfeld says "half the subjects in the low load group puked during the first week of training"!!

And in another study by Fink et al(2016) which was actually about rest periods (which I will get to later); they were using 4 sets of 40% 1RM for squat and bench press to failure,  in non experienced lifters (but involved in sports). All the participants showed significant increase in cross sectional area for triceps and thighs and they all increased their 1RM! The cross sectional increase was 9.8% and 10% in the triceps in both groups in the study. The paper doesn't say how many reps they were doing but the authors say it didn't drop below 12 even on the last set and using their data I have worked out the rep ranges would have been between at least 19 and 36 per set!

The authors say that low load training (less than 30% of 1RM) may cause a prolonged period of post exercise muscle synthesis compared to 90% 1RM.

We know that muscle growth is due to a whole range of factors such as mechanical tension, metabolic stress, chemical release, hormones and more.

In this case the conjecture is high reps may result in sarcoplasmic hypertrophy, so called non contractile protein and fluid. For the average gym jock, this makes no difference. Mass is mass.

Where does this leave us?

From personal experience low strength reps don't increase muscle mass that much in me. But the mass it does produce is qualitatively in my opinion denser and more likely to be the functional strength and power fibres. What is known as myofibrillar hypertrophy. I respond best to higher reps for hypertrophy.

In reality, for most trainers the rep range will vary with the exercise. For example, no one is going to try a 3 rep max rear delts flye, but a 15-25 rep rear delt flye seems reasonable. The same could be said for calves, if you are going to train them. This then comes down to the old adage about different parts of the body having different fibre mixes, if the calves are mainly type I endurance fibres then high reps would work best. Conversely, no one is probably going to do 3 x 35 reps for pull ups, so the exercise itself makes you go into moderate rep ranges.

Some things intuitively don't make sense, for example, if you do 35 reps of deadlifts you are inadvertently doing Crossfit. Whereas, 35 reps of a bodyweight 1 leg glute thrust would work.

The research does seem to show the benefits of high rep squats increasing muscle mass, see my post here on high rep squats. This is a taxing exercise but well worth putting in occasionally.

Exercises like cable flyes and machines lend themselves to high reps 12-15 whereas I think things like your classic dumbbell bench press are better in the 8-12 rep range.

I also like timed sets, set a stop watch for 35 or 45 or 55 seconds and then see how many bicep curls or press ups you can do with controlled tempo. This type of training keeps you honest!

I think many guys avoid high rep training because it is hard and burns, plus you have to leave your ego at the door and venture over to the chrome dumbbells.

Could you use interval endurance/ training?

Given that very high reps of 35 have caused hypertrophy could you not use sprint intervals on a bike or rower or ski erg or hill sprints to increase muscle hypertrophy? If the intervals are all out intense 10-20 seconds I can't see why they wouldn't work. The size of track cyclists legs is probably a testament to this.

I would also think exercises like prowler pushes could result in increases in muscle mass and strength depending on load and timing.

The perfect rep.

One thing I have really being trying to do over the last few months is feel every rep.

It doesn't matter what rep scheme you use if all your reps are crappy.

Really try and feel the muscle you are working on every rep. Let go of the ego of the weight, there is always the temptation to try and move up to the next set of dumbbells on the rack. Before you know it, you are going partial range and cheating the weight up.

Although there are times when partial range may be beneficial such as when doing 21's, in most cases go full range.

Also note in all the studies above they make the participants go to failure.

Lift with focus and intensity!

How long to rest?

The research is not consistent on this issue.

Schoenfeld et al (2015) compared resting 1 minute versus 3 minutes when training 3 sets of 8-12 reps. This research actually showed resting longer was more beneficial for hypertrophy. The authors state that in the long rest group "muscle was significantly greater in the anterior thigh and a trend for greater thickness in the triceps brachii"

However, when you look at the actual data from the study, there is not that much difference between groups. And as the authors state 1 minute is probably too short but 2 minutes would be long enough.

The difference in the anterior thigh would makes sense. As anyone knows, leg exercises such as squats are systemically taxing and need longer rest than some upper body exercises. A tricep kickback might only need 30 secs rest.Therefore, regional hypertrophy in the body may mean different rest periods (and rep ranges) for different body parts and different types of exercises.

Schoenfeld et al state

"Longer rest periods can allow for the completion of a higher number of repetitions and the maintenance of a higher training intensity and volume, and this may allow for greater muscle activation per set."

However, another researcher studying elderly men (average age 68) found a 1 minute rest period was better than a 4 minute one, and resulted in greater gains in lean mass and strength.

And don't forget how much longer it takes to rest an extra 2 minutes per set, that would be an extra 6 minutes per exercise for 3 sets, and an extra 42 minutes if you do 7 exercises. If you used those 40 minutes to do additional exercises and sets with less rest would you get better results?

And could you not maximize time efficiency with rest by doing supersets and if you are alternating limbs, say in a tricep exercise, one side is resting while the other is working?

High reps need less rest.

In a study already mentioned, Fink et al (2016) compared resting 30 seconds with resting 150 secs when lifting 40% 1RM squat and bench for 4 sets.

Both groups got increases in muscle mass and strength, with no significant difference between groups. And the blood work showed the metabolic stress for both groups was the same.

This shows that when doing very high reps, 20-35 - then you can rest less. Caveat being if you have ever tried to rest 30 secs between high rep squats you will blow up or throw up.

Where does this leave us?

Most studies that are not testing different rest periods seem to use 2 minutes.

In reality now I do not measure rest periods, by the time you changes your weights over, take a sip of water, write in your training diary what you just did you will be ready to go again. This means I am probably resting about 60-90 secs at most and no where near 3 minutes. The difference between resting 2 or 3 minutes is very marginal and other factors come into play

If you are mainly interested in strength, definitely rest longer.

Supersets are a good way to maximize rest efficiency, for example superset a dumbbell row with dumbbell chest press.

In my opinion, isolation exercises like tricep extensions and high rep exercises like rear delt flyes will need very little rest, 30 secs, legs will need more.

The caveat is special training techniques like descending sets and rest pause, where rest may be 10 secs or less, which I will cover in part 4 of this series.

In my experience, most clients and women will not rest enough when you are training them, they will rest a few seconds and try and go again. This means you need to educate them and make sure they are going to real failure!

Tempo.

There was a time when tempo was big, mainly because of Ian King and Poliquin programmes. You would see things like 51X0 and 3111 written on programmes.

Normally referring to how fast you should lower a weight, eccentric, then concentrically press it up and may be squeeze and hold a peak contraction.

This seems to have fallen out of favour recently. I would imagine probably because when you are trying to focus on perfect reps and counting to 15, the last thing you want to do is try to count exact tempo as well.

The caveat would be triphasic training, this is using eccentric, concentric and isometric contraction in a specific way. For an explanation of triphasic training go here, and how to apply it here.

The eccentric phase is the part of the movement causing muscle soreness. Sports like Olympic weightlifting and track cycling do not have much eccentric loading of muscle but can still result in muscle mass. (Yes, I'm aware these groups may do some training use eccentric loading and possibly have chemical assistance). Soreness is not necessary for growth but we all like the feeling of DOMS!

In most of the studies I have read they normally get the participants to do a 2 second eccentric and 1 second concentric. This would seem about about right, I would probably go closer to 3 second eccentric and possibly a 1 sec squeeze on things like latpulldowns , with an explosive but controlled concentric. But I wouldn't spend too much time thinking about this.

Of course, I am talking specifically about hypertrophy training here. Strength and power are different.

One thing I would avoid is super slow training, this seems pointless to me, as do super slow concentric phases.

No studies involved women!

Its important to note that none of the studies cited used women. It was the usual young male college student in most cases.

Would women respond differently to high reps, and different rest periods? Who knows. Someone needs to do that research.

Take away points.


  • You can increase muscle mass in all different types of rep ranges, 2-4, 8-12, 25-35
  • Moderate rep ranges are probably better than lower reps for hypertrophy.
  • Keep most of your training in the 8-12 rep range for hypertrophy but..
  • Try some high rep stuff, its hard, and occasional strength work. In other words periodise and vary. Leave your ego at the door, the chrome dumbbells are calling you!
  • You could try 3 total body sessions a week, one strength 3x2-4, one moderate 3x8-12, one high rep 3 x 20-30. 
  • Different exercises lend themselves naturally to different rep ranges and rest periods. 
  • Try some high reps squats!
  • Different body parts can be trained with different rep ranges and rest periods. Rest longer on legs.
  • Rest period, if you are an experienced lifter self selecting will work best.
  • Rest 30-45 secs for small body parts/isolation work and very high reps.
  • Rest 90 to 120 secs for compound movements, legs and taxing exercises.
  • The benefits of resting 3 minutes is marginal at best for hypertrophy and very boring and time consuming. If you have time give it a go and see if it makes a difference.
  • Tempo, don't get obsessed, slow eccentric 2-3 secs, fast concentric, squeeze hold where you can.
  • To increase 1RM do more work in the 2-4 rep range, and rest longer. Bizarrely your 1RM will also increase if you do high rep training with minimal rest.
  • Go to failure at some point. Not on every set, but definitely on some of your work sets.
  • Think about executing the perfect rep and feeling the muscle working probably trumps everything else for hypertrophy.
Next time special techniques - rest pause, descending sets and more.

Coaching Ethos.

How do you create a high level coaching team?

This is a question I think about a fair amount.

These are my thoughts after talking to people who have been in high level coaching teams, observing how organizations like the NFL work and reading some of the literature.

Much of the literature and most of the books are about teams within business organizations. Some of this applies to the 'actual' coaching fitness professionals do. Some of it applies to professional sports teams, but is not so applicable to paying clients. I think it was Mike Boyle who said it is way harder to coach the general public than professional athletes.

I am also assuming you are not a lone personal trainer, in which case you are the coaching team, and should build a referral network for things that may be beyond the scope of your skill set at this moment such as nutrition and sports injury. Unfortunately, many lone personal trainers do not do this, to be blunt they need the money and therefore try to be an expert in everything. Sometimes this works out for them, sometimes it doesn't.

So without further ado in random bullet point format (easily tweetable).


  • Everyone in the team knows their exact role.
  • Everyone knows the exact goal of their team and their part in it.
  • Everyone needs to know the product. Yes that includes the cleaner and the receptionist working one hour a week.
  • Clear metrics on what we are measuring. What is important to us.
  • Consequences for not meeting the metric.
  • Reward for meeting the chosen metric.
  • Regular coaching get togethers. Make the agenda clear, not moaning and gossip. But plans and solutions.
  • Every day, week, month think what did we do well, what could we do better/different. And then act on this.
  • The coaching team should complement each other. They don't have to be clones.
  • Make it clear to customers and clients -'this is what we do'.
  • Make it clear to customers - 'this is not what we do' but we may know someone else who does.
  • Don't try and bend the product to the customer.
  • But be flexible with your product, if the market and the science and the zeitgeist changes you may need to change. But make that change whole hearted, not piecemeal.
  • If the client is willing to work hard, or the customer is a promoter, go all out and give everything.
  • Sack the customer who doesn't want it. Sack the customer who annoys other customers.
  • The basics that every customer expects - clean, equipment works, greeting, acknowledgment from staff.
  • Clear pricing, clear proposition.
  • Don't be afraid of your price if the product is worth it.
  • USP, it could be weightlifting, or rehab, or beginners, or weightloss, or being cheap or group training or being luxury. Choose what it is and embrace it.
  • Let the USP inform every level of your product from marketing, social media presence, staff recruitment to layout of the building or the equipment you choose.
  • Amateurs come across as amateurs. If you are a professional this is how you make your living. It should be all consuming. For amateurs it is a hobby, professionals get paid.
  • None of your team should come across as amateurs. Again this applies to the cleaner, the receptionist and the back room staff.
  • If half your salary depended on retaining members and customers what would you do differently? (Self employed people already get this). Who and what would make the cut?
  • If you are new to the market you may need to discount to get your name out there.
  • If you are established and still discounting there is either something wrong with your business model or your pricing is wrong.
  • Don't phone it in.
  • If you've got nothing on the line what have you got to lose or gain? Managers of big organizations find it hard to grasp this.
  • Your coaches should be constantly learning and training. What does the team actually want to improve at? Organize that training for them
  • What does the team need to improve at, organize that training for them.
  • Everyone should be improving and engaging in deliberate practice. In-house training and external training should be built into the schedule and built into the budget, not an after thought.
  • Use scientific rigour to inform your coaching, but also realize that coaching is an art that requires creativity.
  • Be honest.
  • Be open. Other people can have really good ideas.
  • You don't need to be the expert in everything, but know someone who is.
  • It should be fun. But that doesn't mean it shouldn't also be serious, challenging  and sometimes stressful. Being good at something is hard. being the best is really hard.
  • Listen. If no one is saying anything, you are in trouble.
  • Passion only gets you so far, eventually you need a plan, skills, grit and dedication (cue Record Breakers theme tune from the 1980's with Roy Castle on his trumpet, outside of the UK this reference doesn't mean anything)
1980's flashback.


Of course, all this is easier said than done.

Well, that's all I've got right now. Let me know if you have anything else to add to the list.

Experiments in Hypertrophy: Part 2 - How many exercises per workout and per body part.

In the second part of this series, I expand on my own experiments in hypertrophy, see what other people do and have a look at the science.

See here for part one on training splits.

Once you've decided on your training split, and you know you have to a hit a muscle with at least 10 sets per week, possibly up to 20, and optimally train it at least twice a week, then how many exercises should you do?

Assuming your workout is 60 minutes or thereabouts (excluding any cardio but including at least a quick warm up and some core at the end) I found you can't really do more than 6 or 7 exercises in a hypertrophy workout. In reality sometimes 5 is enough depending on how intensely you are training and the training methods you are using.

So, for example, on a classic chest day, this would be 3 or 4 chest exercises and 2 tricep exercises.

On a total body training day, I found I could do 7 exercises at most, sometimes skipping triceps and only doing 6. Interestingly, In Brad Schoenfelds study where he compared total body training with body part split training this is exactly how many exercises participants did when they were doing the total body training. It is is obvious, one exercise per body part and using the classic bodybuilding delineation of body parts and you have 7 exercises (unless you are the type of person who does a calf, forearm and abductor exercise as well).

What does the science say?... Not much.

I can't find any research that shows how many exercises per body part is best. The advice is generally common sense, hit the muscle from multiple angles and do a variety of exercises.

But you may be thinking, if I have do 10 sets for an exercise, couldn't I just do 10 sets of 10 reps of one thing like a bench press in one workout and then be covered? You would basically be doing German Volume Training(GVT) which seems to get re-discovered every year.

After a while I think this type of training would get boring, draining and you are hitting the muscles from the same angle all the time.

Redundancy.

At the other end of the spectrum you could be thinking, could I do 1 set of 10 different exercises. Here you face two problems, you don't really do an exercise enough to get good at it or know what is the best weight to use and you could end up doing a lot of sub par exercises, and secondly redundancy.

This is where you are essentially hitting the muscle with different exercises which basically do the same thing, you are not optimizing the muscle stimulation. For example, if you do barbell bench press, DB flat press and machine chest press, you are doing a very similar horizontal pressing move for all three exercises.

However, if you did incline DB press, flat DB press, pec flye and possibly a press up - you will be hitting the muscle from different angles and with different actions. You could do all these in one workout if you have a dedicated chest day or if you are hitting a muscle multiple times per week you could do 1 or 2 of these per workout. This way you will find you can lift more, for example, a pec flye after 2 other chest exercises will involve lifting less weight than if it is the only chest exercise you do.

Different body parts, different approach.

The number of exercises you do will depend on the body part. For example, for back you are looking for at least a vertical pull and a horizontal pull (row) to hit different muscle groups.

If you look at the way muscles fibres run (see the picture of the trapezius) and if you want to be fancy use the word 'pennation', you can see that some muscles are not going to be fully worked with one exercise.

Look at the different way the muscle fibres run on the trapezius, the  'pennation' if you want to get fancy. How many exercises do you need to train all of them?


The shoulders are another classic example, with 3 deltoid heads, and the rotator cuff muscles and the trapezius, you could do 4 or 5 exercises which don't have much crossover.

Whereas with biceps and triceps, quite a few people over do it, considering these muscles are also being worked with chest, back and shoulders. Even, when I did a dedicated arm workout I only managed to do 3 bicep and 3 tricep exercises.

How far do you want to go?

How many exercises you do is also dependant on how far you want to go. Glute/booty/ posterior training is very much in vogue at the moment. In the past you may have done a quad exercise, a hamstring exercise and possibly a calf one.

If you are doing 10 exercises for these muscles you are either in an LBT class or Brazilian.


But you could do a hamstring exercise for knee bend, a hamstring exercise for hip extension, glute exercise for hip extensions, adductor, abductor, quad multi joint, quad isolation knee extension only, calf gastrocnemius, calf soleus. And that's only one exercise per body part, before you know you can be doing 10 plus exercises and be in the gym 2 hours. Which begs the question of how intense you training is?

Nuts and Bolts: Strength hybrid, pure hypertrophy, circuits.

In my recent experimentation (and as I said in part 1, no it's not a real experiment) I have gone pure hypertrophy, eschewing the big compound lifts and low reps.

But if yo want to do a more strength hybrid split, powerbuiding approach or something like Wendlers 531, then the split would something like this:

Day 1:
Squat 5x5
RDL 4x8
Accessory work: Walking lunge etc

Day 2:
Bench press 5x5
Row 4x8
Accessory work: DB incline press, seated row etc

Day 3:
Deadlift 5x5
Bulgarian split squat 4x8
Accessory work: Leg curl etc

Day 4:
Military Press 5x5
Pull Up 3xmax
Accessory work: Lateral raise, rear delt etc

Generally as you go into the strength range you have to do less exercises because it takes so much time, as anyone who has ever done the Olympic lifts know. 10x2 with 2 mins rest and set up, and before you know it one exercise has taken 25-30mins. Add in some mobility work, warm up sets and you'll be lucky to get 2 exercises in a 60 minute workout. And it is very taxing.

Whereas, 3x10 with 30-60secs rest takes less than 5 minutes per exercise, hence you can do more at a lower percentage of 1RM and it will be less systemically fatiguing.

In circuit training you could easily do 10 exercises, but I would not call this hypertrophy training in the purest sense.

3 exercises will do it: What the science inadvertently shows.

In a study I really like the design of Schoenfeld et al (2014) compared 7 setx x 3 reps and 3 sets x 10 reps training schemes. A strength group and a hypertrophy group both training to failure. Both groups were experienced trainees.

A few things stand out from this research:

1) Both training schemes resulted in hypertrophy
2) They were both only doing 3 exercises per workout but still got results (increased muscle mass in the biceps). They either trained using a total body scheme, 1 push, 1 pull and 1 leg exercise per workout for 7x3 or for hypertrophy 3 exercises per body part; a day consisting of three chest exercises, another day three back exercises, and a day of three quad exercises. Note, no isolation exercises for the biceps.
3) The 7x3 group took over an hour to complete their routine whereas the 3x10 group took only 17 minutes
4) The strength group got more general fatigue and mental fatigue. Strength training day in day out is hard to maintain for weeks on end.

This echoes my own experience of strength training with no variation in volume or rep ranges. You begin to ache, start to get injured and breakdown. Strategic planning placement of higher rep work and deload weeks should stop this.

A 17 minute workout is highly achievable and means you could add in more volume or another body part such as biceps. Plus you could easily repeat this session more than once per week, thus hitting every body part twice and getting twice the volume of 18 sets per muscle.

There is also a certain amount of personal preference here and what you respond to. Personally, if I do 10x2, 7x3, compound exercises, I get stronger but my muscle mass does not increase. Eventually if I try to go heavy on things like barbell bench press and deadlift I break down.

If I want to increase muscle mass and generally not break down I have to keep in the higher rep ranges, towards 10-12 reps, and even some higher rep work. And I find isolation exercises work for me as well.

Where does that leave us?

A brief survey by me in the gym and online showed that 99% of people train using some kind of body part split. With most people doing a class Chest & Tri's, Back & Bi's routine. Most people were doing about 3 to 4 exercises per body part and 1 or 2 for muscles like biceps and triceps. Th exception being younger people, some of the younger guys doing 6 exercises for chest and one girl doing 11 exercises on leg day! Possibly younger people can get away with more volume, or they have to lower the intensity to complete these marathon routines and therefore don't get enough stimulus for growth.

Here are some example routines from my training diary. The actual exercises are not important at this stage (I’ll get to that in another post), at this stage I’m trying to give an idea of how many exercise per body part.

Chest & Triceps
Incline cable cross press
Incline press plate loaded
Cable flye high to low
Pec flye machine
Tricep tall kneeling rope press
Cable kick back

13 sets for chest, 4 exercises

2 exercises for triceps, 5 sets

Core: stir the pot

Back & Biceps

Incline bicep curl
Seated Cable row
Meadows stretcher
Diverging latpulldown
DB Pullover
Drag curl

Back 4 exercises, 13 sets,
Biceps 2 exercises 6 sets

Legs

Hack squat
Leg curl machine
1 leg mike boyle pistols
Nordic hamstring curl
Hanging leg raise

2 exercises 7 sets quads,
2 exercises 7 sets hamstrings

Chest & back & Triceps – would be repeated again in the week

Flat DB Press
Chest Supported Row
Cable Flye
McGill side pulldown
1 arm rope pushdown
1 arm cable kickback

2 exercises chest  6 sets
2 exercises back 6 sets
2 exercises triceps 4 sets

Push – Shoulders, Chest, Tricep

Flat DB Press
DB Arnie Press
Bottom to top cable crossover
Lateral raise
Pec Dec
Rear delt
Overhead tricep ext

3 chest exercises 9 sets
3 shoulders  9 sets
1 tricep 3 sets

Arms only day

DB skullcrusher
Incline DB curl offset grip
Drag curl
Kneeling bench supported tricep ext
Kneeling bench supported bicep curl
Rope over head tricep ext

3 exercises biceps, 3 triceps,
9 sets each

Total Body routine

DB Chest press
Seated Row
Barbell bicep curl
Lying leg curl
Goblet squat
Lateral raise

1 exercise per bodypart, 3-4 set each body part, 3 or 4 different total body routines per week = 12-16 sets.


Of course, these are just some random entries from my training diary and don't give you an actual routine to follow. It's not meant to be the ideal training programme in any sense, after all I was experimenting.

They don't show what rep ranges I used, they don't show what techniques I may have used such as rest pause, descending sets and so forth. Or how to fluctuate the volume, you might deliberately over reach for a couple of weeks on a body part and do multiple exercises, and get 18-20 sets and train 6 x week. And then you might back off for a week with some total body training session and train only 3 x week with only 1 or 2 exercises for a body part and 10 sets total, in the hope you would super compensate.

In summary.

The research is scant and says to hit muscles from multiple angles

Most people naturally gravitate towards 5-7 exercises per workout unless they are doing strength training or circuits.

3 to 4 exercises for big muscle groups and 2 to 3 for smaller muscle groups per workout is about the maximum you can do. Anymore than this and I find your intensity and focus would start to suffer. If you are doing 5 or 6 exercises per bodpart per workout there will probably be redundancy and replication.

The art is having enough exercises and variation for stimulus, but not so much that it is no longer optimal.

Next time.

In part 3 of this I will cover what rep ranges to use, how long to rest and those special training techniques like rest pause (extended sets) and descending sets.

Forming new habits. Part 4: Memory.

Every habit you have is embedded in your memory somewhere. 

For part 1,2,3, go here, here and here

The more you practice a habit, the more the neural pathways are laid down. The pathway gets stronger and the memory becomes consolidated. As the neuroscience adage says 'neurons that fire together, wire together'.

But you memory is unreliable. It does not store fixed digital files, they change over time. Less like a digital photo and more like a painting you keep adding to and re-touching. Your memory of playing frisbee at 10 years old is different when you remember it at 14 years old to when you remember it at 50 years old.

You will have attachments to certain activities and foods beyond the utility of getting enough calories to survive and filling up your days with stuff to do.

Think of all your favourite comfort foods, they will probably have a memory attached to them. A roast dinner at your grandparents, a cheese sandwich after school, being given a certain chocolate bar as a treat. That food you had once on an amazing holiday.

And you may have an aversion to other foods because of a bout of food poisoning, or that time you got so drunk on Sambuca that you can never face drinking it again.

And you cannot escape your culture.

Pepsi vs Coca Cola.


In one famous study (McClure et all, 2004) the researchers compared peoples brain activation in an fMRI scanner when they were drinking Pepsi and Coca Cola. They are both essentially brown sugary drinks, so should activate the same areas of the brain.


When the participants didn’t know whether they were drinking Pepsi or Coca Cola the VMPFC lit up, an area of the brain that relates to taste.


However, when they were told they were drinking Coca Cola the DLPFC and hippocampus were activated. This didn’t happen when people thought they were drinking Pepsi.

The DLPFC is involved in working memory and perception based on previous experience. The hippocampus is involved in memory recall.

The coca cola was causing a memory recall in people, not just a taste sensation. The influence of culture and brand knowledge had made their brain remember Coca Cola (bear in mind they didn’t actually have to drinking Coca Cola for this to happen, they just had to think they were).



If you're American this is probably embedded in your memory, whether you want it to be or not.

Interestingly, the memory parts of the brain were not activated for Pepsi. And even the people who had a stated preference for Pepsi only showed activation of the memory parts of the brain when they though they were drinking Coca Cola.

This study was in the USA, and shows how much Coca Cola is part of peoples culture and upbringing in that part of the world.

For me this wouldn’t happen for Coca Cola, but it would probably happen for a cheese sandwich on white crusty bread and a cup of tea. These were more significant foods and drinks for me. Or possibly even Tizer, or Irn Bru if your Scottish!

If you're British and of a certain age this is in your memory. If you're American or Chinese this means nothing.


You cannot separate yourself from your culture or your memories which are hard wired into your brain.

Now think back to exercise. If someones memory of exercise is being made to do it at school, going for runs in the freezing cold and hiding behind the cricket pavilion for a cigarette; this is what they think of when they think of running. However, they may have more positive associations with dancing or cycling. Who doesn’t like riding their bike as a kid? Or swimming on holiday?

Spreading activation. Run = school = cold = bullying PE teacher!

Spreading activation theory is how your brain groups things together.

The networks in your brain seem to group words and objects together. Think pets, and you brain might thing dog or cat (in western culture) . You can prime someone by using associated words. Say the word carrot, and someone takes longer to recall the word doctor, say the word ‘nurse’ and they recall the word doctor a lot quicker.

Your neural network is dependent on your experience and your culture. You could prime yourself by associating certain feelings and words with exercise.

For example, for me running is not like the example above, but is running with my Dad as a kid - going to cool places, being outside.

And for a lot of new people going to the gym, especially women, I suspect that when you mention the words 'lifting weights' there neural network goes with the only examples it knows: weights = olympic = massive guys lifting massive weights = masculine/drugs. 

But could you change this, can you create a new pathway?

False Memories.

Elizabeth Loftus and her team were the first team to show you could implant a false memory in people, the memory was of being lost in a shopping mall as a child. It has to be a plausible memory, it  is less likely you could implant the memory that someone climbed Everest as a child.

They have also managed to do it with food (Bernstein et al, 2011). 

In one study (where the participants did not know it was about false memory, but about food preferences) the researchers managed to plant false memories in subjects to make them believe they had a bad experience with egg salad or strawberry ice cream ( up to 40% of participants). So much so that when offered these food one week or several months later they avoided them.

They also managed to plant a false memory about a 'healthy food', in this case, Asparagus, making them believe they love it the first time they had eaten it. They managed to convince 50% of participants they had loved Asparagus the first time they had eaten it. They then offered them a choice of foods to eat at a later date, the people with the false memory chose Asparagus more than those without the false memory. The participants with the false memory also said they would pay more for asparagus and choose it as a preferred food to have several months after the study.



You can be made to think you loved this the first time you ate it. Maybe you really did?

However, they were unable to plant false memories about a bad experience in the past or fake food poisoning with cookies (biscuits) or potato chips (crisps). This could be because these food are too tasty to give up and too common OR it could be intuitively as humans we generally know we don't get food poisoning from crisps.

Also, note they were not able to plant the false memory in everyone, more than half the people did not accept the memory.

The researchers also managed to do it for alcohol as well.

From a real memory point of view this makes sense, you aversion to Sambuca after that heavy night of shots years back or that terrible bout of food poisoning means you avoid a certain restaurant or seafood. And if you are allergic to something like peanuts or red wine your are very likely to avoid it.

Whats less clear is if you could deliberately plant a false memory in your self, while knowing you are actually doing it.

Be careful!

There is something called covert sensitization, which is essentially the idea of gradually associating a feeling of nausea/sickness with a food until you don't want it. Of course, this may result in you never wanting a food, even something as tasty as cheese. And lets not forget obesity and healthiness goes beyond one food group.

More useful could be the idea of making yourself want healthy foods more. And then associating these healthy foods with healthy words and healthy positive images in your brain.

You could make yourself remember that you loved running at school, you liked all vegetables as a kid and can't get enough of them.

Of course, there are techniques that people already use like hypnotism and NLP. Even though these have been considered fringe methods up until now, the research which uses quite basic methods of visualization shows there could definitely be some merit in some of these approaches.  

This is not going to happen over night, like all visualization techniques you have to practice.

What is real and not real?

There is another famous study, where one group of people learned to play a sequence on the piano actually sitting at the piano, and another group visualized practicing it. After 5 days, both groups showed an increase in the motor cortex where the fingers are controlled from in the brain.

Think about this for a second, not only did it show the brain in adults is plastic and can physically change when learning a new skill. It can be changed just by visualizing a new skill!

Now, you have to make your visualization targeted, you can't just sit there and pretend you are Elton John or Jimi Hendrix. You have to make your visualization a clear practice.

And one last study for you, Ganis et al (2004) Got one group of participants to look at a sketch of a shape, and another group to imagine the shape while in an fMRI scanner. There was a lot of overlap in the regions of the brain activated, in fact about 90%. There wasn't complete overlap, but there was a large amount of similarity.

This shows how powerful imagination can be.

Take home.

Hopefully, this has shown that your brain and habits are not fixed. After all people give up smoking and start exercising every day, and some stick with it.

You brain is plastic, you can change how you think about things and what your memories are 'telling' you.

Always remember that what you believe and remember and like are all products of the culture you were brought up in, at a certain point in history. And even though these things can be quite deeply embedded, there is no reason why you can't use strategies of visualization and mental imagery to change the things that are may be not working for you now.

You can visualize new skills, you can create positive word associations with healthy foods and exercise and probably even convince yourself how much you love vegetables. But, be careful, don't create a permanent aversion to cheese or coffee or bread - what could be worse. Live your life!
