Following on from his last blog post on Hypertrophy mistakes everyone makes and how to avoid them, our personal trainer George looks at five key factors for exercise selection. A warning, this one is pretty in-depth, but will be perfect for anyone looking to improve their anatomy or hypertrophy knowledge. If it goes over your head, don’t panic! It’s up to your personal trainer to have this knowledge and make it work for you.
You’ve all heard of programme design, but how about exercise design? It’s probably not something you’ve come across, but hopefully come the end of this blog post you’ll have a few more tools in your belt to start tinkering with some of your favourite exercises. Heck, you might even need to throw some out completely!

Just to be clear before we begin, using only one or two of the following factors to explain something is likely going to get you into trouble, the key is to understand all pieces of the pie. After all, if all you have is a hammer, everything looks like a nail.

Most of these topics aren’t mainstream and they’re pretty ‘un-Instagramable’ – so, settle down, buckle up and prepare to have your mind-blown!

I’ve popped in a couple questions just to lighten things up – you’ll find the answers at the very end.
Joint Mechanics
Understanding joint mechanics gives you an indication of where an exercise increases and decreases in perceived weight throughout a movement.

It’s important to know the distance of the load from the axis, in our case, the joint; the further the weight is from the joint, the heavier the load ultimately becomes, so more force has to be imparted by that muscle. This is effectively what moment arms are.

A note on cables; cables create a constantly changing force angle on the lever (arm). That is, the load will appear to be heaviest when the cable is at 90^o to the arm – play around with this yourself and let me know what you find.
Example: A dumbbell fly is fundamentally the same as a dumbbell press but with the lower arm extended, increasing the moment arm and making the load ‘heavier’.
Question 1: Which creates more torque at the joint; 5kg held horizontally at 0.5m or 5kg held horizontally at 1m?
(hold that thought, answers can be found below)

Muscle Mechanics
A muscle is not a muscle! Throughout the body, we have a number of different muscle types, and I’m not talking fast twitch vs. slow twitch here. Muscle fibres only pull in the direction in which they run, due to fibre direction and insertion points, each type differs in where its max strength lies.
Fusiform – e.g. Biceps

• One line of pull – fibres run directly from one end to the other, converging at a common origin and insertion
• Provide a contractile ability that is strongest in the midrange. Their strength curve almost replicates your typical bell curve.
• Provides more range of motion and speed, but reduced force capability

Pennate – e.g. Quadriceps, Hamstrings, Triceps, Deltoids

• Contain a mini-tendon within the muscle belly – muscle bellies within muscle bellies ey’! Their fibres run ‘slanted’ between these tendons, therefore do not contract directly from origin to insertion.
• Have an increased advantage to pull in a more lengthened position
• Suffer a drastic drop off in advantage as the muscle contracts and shortens
• Provides less range of motion and speed but higher force capability

Convergent – e.g. Pectorals, Latissimus Dorsi

• Originate at varying points and converge at a single insertion, therefore provide an almost infinite number of lines of pull
• Have a greater advantage in a more lengthened position due to the fibres having a better line of pull towards the originQuestion 2: Which muscle type(s) might benefit from a higher proportion of lengthened loading?

Resistance Profiles
Resistance profiles shows how tension/force changes in the muscle throughout the range of motion of a particular exercise in isolation.

Going back to our above example, a dumbbell fly is increasingly heavier the further the load (weight) gets from the joint, and lighter the closer it becomes.

Strength Curves
The typical bell curve we all associate with strength curves is correct, well 80% correct. However, the muscle mechanics we spoke about earlier have the ability to shift our strength curve more toward an extreme range advantage, shortening the curve entirely or increasing the total peak tension.

Question 3: How does the strength curve for a pennate muscle differ from the others?

Neuromechanics
What you intend to do with the weight is vital to where tension is placed! A steady and controlled movement of an object has a constant mass throughout, whereas acceleration causes something to feel heavy from the start and lighter as it begins to move.

In order to overcome some gaps caused by all four of the previous factors, we can add in the use of momentum and design a more effective exercise. Just to add; ‘explosive’ and ‘accelerating’ do not mean throw!
Example: Dumbbell lateral raises are ridiculously hard at the top. We can accelerate the weight through to the top, where it naturally gets harder.

Information Overload? Where Do I Start?

I know, I get it – it may take a couple of reads and a few weeks of mulling over (it will, trust me). But truly understanding each of these areas and being able to instinctually integrate them into your programming is THE ultimate skill! Giving you the principles behind these five factors and how to use them is far more beneficial than giving you specific ‘to-dos’.

Going back to our original statement; “The most effective exercise for a given muscle is one that has the ability to perfectly match the output capability of that muscle throughout its entire range of motion.” – as I briefly explained in my last blog.

Maximally efficient exercises and ultimately, workouts, can be achieved by understanding how each of these factors interact with one another, and then making adjustments accordingly to match output capability.
Here are some examples to get you started…
Example 1: If an exercise is hardest where a muscle is mechanically weaker, it might be beneficial to decrease the difficulty there OR increase the difficulty where the exercise is easiest to balance things out. 

Example 2: If a muscle is drastically stronger in a more lengthened position, it might pay to spend more time there with some partial reps.
There we have it – I did say only understanding one or two of these would get you in trouble, didn’t I?

Q1:  5kg held horizontally at 1m
Q2: Both pennate and convergent
Q3: More force created but over a shorter range of motion

For some people, sticking to a calorie controlled diet and losing weight can be an easy task, but for most of us (myself included) it can be a bumpy road with many setbacks along the way.

This is completely normal and you shouldn’t become disheartened if you fall off the band-wagon; the important thing is to recognise when you’ve fallen off, why you fell off and what you’re going to do to get back on it.

A study published this year in the The Society of Behavioural Medicine looked at the reasons people lapsed on a diet. I’m not going to bore you with the specifics as it’s the sexy stuff we’re really interested in.
So here we go; over a one year period it was found that:
• Unintentional food intake was the most common reason people lapsed i.e. the foods you know aren’t good for you but you love them anyway (pastries, cakes, ice cream, chocolate and crisps)

• Lapses were highest when at home – 46% of lapses occurred at home compared to at work or when eating out.

• The most common time for a lapse was in the evening – between 6:00pm and 9:00pm

• The risk of lapsing was higher at the weekends compared to weekdays

• Feelings of hunger and deprivation, and the availability of delicious foods were also associated with an increased risk of a lapse
The researchers also discovered that people who were stressed, angry, lonely, sad or bored lapsed more frequently than those who had a more rounded emotional state.

Now, if you’re anything like me then ninety percent of your lapses coincide with these findings.

Personally, I find it much harder to stick to my diet when I’m working from home and over the weekend than during the week. Come the evenings, it’ll be around 8:30/9:00pm when I start craving the chocolate and all things sweet. These cravings are then further exacerbated when I’m bored, stressed or when I know I have bar of Dairy Milk sat in the fridge door – it can be so hard sometimes!

So when it comes to diet lapses you have two options. The first is to adopt a mind-set of “oh well, science says I’m bound to fail, this is out of my control.” The second is to look at the strategies above, see which ones you identify with and then use this information to help prevent further lapses.

If you can build in a few strategies to help reduce or better yet, prevent a dietary lapse, then you’ll be onto a win and a far more successful weight loss journey.
Here are a few examples:
1. Access to delicious and highly desirable foods was the biggest cause for people to lapse. Find ways to control your access to these foods, simply by removing them from your cupboards and not letting them enter your home. Also try limiting your exposure and visibility to them through photos on social media, television ads and cooking programmes – programmes such as Bake Off really aren’t going to help supress your cravings for these types of foods!

2. People are most likely to lapse when at home – If home is the place where you find self-control difficult then ask yourself why? Why are you more tempted by foods when at home than anywhere else? Is it because of boredom, access to delicious foods, loneliness, habit, or lack of routine? If you’re able to find what pulls that trigger you can then think of ways to prevent it. Through working with clients I’ve found boredom, access to tempting foods and habit to be the main reasons they lapse when at home. Why not set yourself a new healthy habit. When you’ve got home and relaxed for a while, why not go for a daily 20-minute walk to increase your step count and prevent you eating?

3. The window between 6:00pm-9:00pm is the dangerous time for diets! This makes a lot of sense as most people will be returning home from work, often feeling stressed, hungry and tired, so will pop the kettle on for cup of tea, in which case biscuits are usually nearby, or they may pour themselves a glass of wine (or two, three, and four… oh God, I’ve drunk the bottle).

Habit plays a huge role here as there are many actions such as walking through the front door, popping the kettle on, sitting down to watch TV, that all spark an unconscious cue for self-reward. Being aware of these actions and the cues they spark can really help you to reduce the acts of self-reward, and therefore what’s being put in your mouth. – If you wish to know more on why habits exist and how they can be changed, I strongly recommend the book: The Power of Habit by Charles Duhigg.

4. Emotional state dictates whether a person is likely to lapse. If we’re bored, stressed, lonely or sad we tend to reach for the snack cupboard to help cheer ourselves up. Last week I talked about how tryptophan can help alleviate some of these emotional-based carvings.

Boredom and stress seem to be the biggest culprits for food cravings. Boredom often occurs in the evenings when we’re sat around with nothing really to distract us. Plan your evenings with activities such as going for a walk after dinner, attending a local book club, signing up to a team sport, or even going to the gym. These will help to provide structure and alleviate boredom, all while taking your mind off food.

5. The feelings of hunger and deprivation led to a greater lapse rate –  Opt for higher satiety foods to help minimise the feelings of hunger and deprivation, which impact lapse risk. Meals that are high in protein and fibre will help to keep you feeing fuller for longer. Also, look at foods with a high-ranking Fullness Factors (FF); these are foods that are more likely to satisfy your hunger with fewer calories. Examples include potatoes, watermelon, beansprouts, eggs, popcorn, porridge and steak.

These are just a few strategies you can put in place to help ensure you stay on track. Admittedly, it would be unrealistic to expect everyone who starts on a diet to adhere to it 100% of the time, we’re only human after all. So it’s important to be aware there will be times when you encounter a lapse, and although you may not be able to fight it you can reduce it. Swapping certain foods for others can help reduce the caloric intake of a lapse.
Here are some great food swaps that you can use:

• Ice cream swapped for Alpro ice cream
• Slice of cake swapped for a protein bar (try a Grenade bar)
• Crisps swapped for popcorn
• Glass of wine or beer swapped for gin and slim line tonic
• Sugary beverages swapped for diet versions
• Crackers or biscuits swapped for oatcakes or rice cakes
There you have it, a few stretgies that may just help prevent you from having a minor stumble off the band wangon.

Do you crave carbohydrates when you’re dieting? Well, this could be why…

Tryptophan is an amino acid that is converted to 5-HTP, which in turn up-regulates the production of serotonin – the happy hormone of the brain!

Low levels of tryptophan will undoubtedly lower the uptake of serotonin, and expose you to:

• increased susceptibility to depression
• increased craving for sugary foods
• low mood
• increased aggression
• increased hunger  – these symptoms seem to be a lot more magnified in women

Unfortunately, tryptophan does get depleted when dieting, by as much as 15-20% when calories are set at 1,200 or lower (Strasser. 2015). It’s a big reason why it becomes very difficult to actually stick to a diet and not be tempted to binge and overeat.

Why?

Well, it’s important to know that increases in glucose and insulin in response to a high carbohydrate consumption will trigger an increase in brain tryptophan and serotonin synthesis (Benton. 2002).

If you’re someone who experiences any of the above symptoms when on a calorie-controlled diet then it may well be worth increasing your consumption of tryptophan. Only recently, scientists from the University of Barcelona were able to show that treatment with tryptophan-rich protein foods improved emotional processing, mental energy levels and reaction time in middle-aged women.

Taken in dosages of 400-1,000mg/day, it has been shown to:

• reduce food intake (up to 18% more than placebo in a 1989 study w/ obese women | Ceci. 1989)
• increase weight loss – found in a 12-week study with obese women (Cangiano. 1992)
• reduce the food intake – specifically carbohydrate intake in both male and female with type II diabetics (Cangiano. 1998).

Where can I find Tyrptophan?

You can either choose to supplement tyrptophan in the form of 5-HTP (the easiest way) or to increase your intake of tryptophan rich foods for example:

• Elk
• Spinach
• Eggs
• Spirulina
• Soy protein
• Crab
• Halibut

A go-to supplement I recommend would be this one as it’s rather potent at 200mg per cap!

So, if you find yourself ‘pulling your hair’ out when dieting or dreaming about dancing doughnuts and prancing pretzels, it may be a sign that your serotonin levels are a little low and upping your tryptophan may not be a bad idea.

Last Friday I talked about the mind-muscle connection, and how if we think about a specific muscle working, we can in fact increase its activation and the amount of force or effort it’s exerting on a load.

Today, I want to talk about how we can spark this link from mind to muscle and establish this all important connection.

It’s no secret; people who are new to training tend to have a poor biomechanical feedback mechanism, meaning they find it difficult to feel a muscle when exercising it. As their training age progresses, so too does their ability to engage the right muscle for the exercise.

In all the years I’ve been a personal trainer I’ve (typically) found the muscles we’re unable to see i.e. our glutes, lats, upper back and hamstrings, tend to be harder to feel and engage compared to those that we can see, such as the biceps, quads, abs and shoulders.

So, how can we teach people to start engaging their muscles and to improve their mind-muscle connection?

Well there are two tricks we can use,

1.Internal and External Cues
2.Touch

all of which have proved to be very beneficial. But today I want to talk about internal and external cues.

Cues can typically be categorised into those that have an internal or an external focus. Internal cues are instructions that direct a person’s attention towards a part of their body, such as muscles and joints. External cues have a more external focus, instructing a person to focus their attention on their surroundings, outside of the body. These are generally used when the goal is to produce power or increase performance.

Generally speaking internal cues help to:

• maximise muscle contraction
• maximise muscle activation
• improve technical form

whereas external cues help to:

• maximise strength
• maximise power, speed, velocity and acceleration
• maximise precision and coordination
External cues have been shown to be far superior to internal cues for maximising performance (Bredin, Dickson & Warburton 2013). If you’re an athlete or competitive sportsman/woman then focusing mainly on external cuing would certainly be the way to go however, we’re not athletes (well, I’m certainly not).

Most of us are simply looking to be able to effectively activate certain muscles in the right order, at the right time –  cue internal cueing.

For years, bodybuilders have been implementing the use of internal cues to help improve the mind-muscle connection. Research has shown by directing your attention and focus internally to a muscle or joint you can increase a muscle’s engagement and the level of contraction (Snyder & Fry. 2001).

Here at Hall Training, we often provide internal cues to our clients to help them to feel and engage certain muscles.

Here are just a few we like to use:
The Lats:
When performing a lat pulldown, we encourage the client to keep their chest up and imagine driving their shoulder blades back and down into their hips, leading with the elbows –  internal verbal cues help to increase latissimus dorsi activity compared with no cue (Snyder 2009).
The Glutes:
For glute engagement, we encourage the client to imagine they’re trying to crack a walnut when coming up into hip extension, or to imagine they have a five pound note between their buttocks which they’re trying desperately to keep a hold of – both cues really help to keep the glutes squeezed and muscles contacted. Researchers have reported providing internal cues during a hip extension led to increased muscle contraction (Lewis et al. 2009).
The Pecs:
When performing a bench press, it’s common for most people to feel it in their triceps or shoulders rather than the muscle they’re trying to work, which would be the chest. By instructing the client to push their hands together against the bar as they push upwards,  along with imagining the two elbows coming together in an arch motion, it’ll make the exercise more focused on the chest muscles.

Research has also concluded that in response to chest cues, subjects were able to increase the amount of activity (22% increase) placed through the chest muscles during the bench press (Snyder & Fry. 2011).
The Biceps:
For men this is never really an issue, but females tend to have a hard time contracting their biceps. Why? I have no idea, maybe because they’re not as vain as us men! Anyway, one trick we use is to imagine the elbow coming up to meet with the shoulder when performing a bicep curl, and then really squeezing it at the top like a balloon, imagining you’re trying to pop it – these internal focuses help to increase bicep activation and recruitment.

So, there you have it; a few little tricks to help bridge the connection between mind and muscle. The next time you go to the gym, try directing your attention away from what’s around you and start thinking about what’s going on inside you… you never know, it may just help you to feel muscles you never knew existed.

This month our level 4 trainer, Pete reviews the latest fitness and nutrition research from July. This month, Pete looks into how much protein you need to build muscle strength and size – more isn’t necessarily better. Can caffeine actually make us stronger… and how a simple trick can increase the recruitment of your glutes in a squat.

So pop the kettle on, sit back and enjoy!

1. Periodising your training will make you stronger
OK, so here’s something some of you may have been wondering. Is it actually worth getting a proper periodised training programme from a personal trainer instead of just rocking up to the gym and doing a workout? Well, this month Williams et.al conducted a meta-analysis (a study which examines the results of lots of different studies) looking at whether periodised models elicited a greater increase in maximal strength as opposed to non-periodised methods. And the answer is . . . yes they do! The results of multiple studies corroborate the findings that periodisation of programming saw a greater benefit for maximal strength in upper body and lower body multi-joint movements.
I was very happy to read that all the time we spend writing out weeks of programme cycles for clients will be helping them to achieve their results faster.

2. Protein supplements will help your gains
The easiest way to think of this second study is as the daddy of studies into protein supplementation! It is another meta-analysis that took data from 49 studies and evaluated the results in order to ascertain the:

“effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults”.
Clearly, with so many studies included in the analysis, there was a great deal of variation with regard to the subjects that were used; there were a few studies who used trained individuals but the majority of the interventions were carried out on un-trained subjects. All of the studies had the subjects training ≥ 2 times per week, and lasted for between 4-52 weeks. The majority of the studies supplemented with whey protein but soy, casein, pea, milk, whole foods and protein blends were also used. It is also important to note that although the protein intake was increased the total daily energy intake did not increase.
The meta-analysis revealed that:

 “protein supplementation increased 1RM strength (by 2.49kg), fat-free mass (by 0.30kg), muscle fiber cross-sectional area (by 310μm2) and mid-thigh muscle cross-sectional area (by 7.2mm2).”

What these numbers show is that adding supplemental protein will aid with both size and strength.

The type of protein did not seem to have a significant effect on the results, and it’s also interesting to note that there did not appear to be any benefit of increasing protein above 1.6g per kg of bodyweight every day.

3. Will caffeine make me strong?
When you read this title I’m sure that many of you are thinking “please say yes!!”. Caffeine has been studied lots regarding endurance, but not as extensively when it comes to maximum strength. This month we had a study that looked into precisely that, and what’s even more exciting is that the subjects of the study were trained individuals (as often studies will be done with untrained individuals).
In summary, the results showed that ingesting caffeine had an acute impact on maximum lower body strength and on maximum upper body high-velocity strength. It was surprising that there appeared to be no reason as to why maximal lower body strength was increased but the same was not true about maximal upper body strength.
For those of you who are keen to pop this bit of info into practise, the numbers used in the study were 6mg of caffeine per kg bodyweight and it was ingested 1 hour prior to training.

4. Should we ban(d) squats to target the glutes?
Sorry for the teasing title and for getting a few hopes raised the research had shown that everybody should stop squatting immediately! Unfortunately not, this piece of research is actually about what we can do to get more bang for our buck from the squat. The aim was to find out whether popping a band around the upper thighs would increase glute activation, and to see if it would have any effect on the number of reps that could be performed at a given weight.
Interestingly, the only effect that was seen through adding a band was that EMG for the gluteus maximus and gluteus medius were increased for both the eccentric and concentric phases of the squat. EMG amplitudes for the bicep femoris and vastus lateralis were unchanged when the band was added. There was also no change in the amount of reps that could be performed at either 80% or 60% of 1 rep max.
All in all, if you have a resistance band and you’re looking to get a bit more glute work into your training, try popping it around your thighs when squatting and it will make the glutes work harder without negatively affecting other muscles.

5. Train quicker to get faster
Here’s an interesting one with slightly surprising results! This final piece of research was designed to compare the effects of different forms of hamstring training on strength, activation and sprint performance. Some of the subjects carried out low volume training with a heavy load but low velocity while others used a resistance band at high velocity. As you would expect, the heavy load training increased 1 rep max strength on the leg curl while there was no difference in the banded group. However, when sprint times were measured both from a static and a flying start, the banded group improved on both, while the subjects using the heavy load saw no improvement. High-velocity training seems to have a better transfer to high velocity athletic activity. If you want to be quick then train quick!

Many personal trainers, coaches and gym-goers seem to think that if you a lift a weight from A-to-B, the muscles involved in that lift will be activated, while others (more sensible folk) believe a muscle is only really activated in a lift when you’re thinking about it – this is known as the mind-muscle connection.

So who’s right, and do we really need to be thinking about the muscle we’re trying to work, or can we afford to let our mind wander elsewhere?

Well, the research on this topic is limited and mostly anecdotal, however I’ve managed to dig up a few studies that can shine some light on the topic.

The largest study I found was by glute expert, Bret Contreras. He took a group of subjects and using EMG data, found whether the load, cadence, and form dictated muscle activation, or whether it’s possible to mentally steer muscle activation to individual muscles using the power of the mind.

It’s very important to note that the load, speed, grip-widths, stances, bar movements and joint ranges of motion were all kept constant between the two groups as otherwise these factors would ultimately sway the outcome.

The results are somewhat surprising! There’s certainly evidence to support that the mind-muscle connection does in fact exist, but only for certain muscles:

(source: t-nation.com)

The glutes seem to have the greatest influence of recruitment, with a 32% difference in recruitment when thinking about them working to not working. During a back extension, muscle activation only reached 6% when subjects weren’t thinking about them compared to a staggering 38% when they were actively thinking about them. Overall, glute activation was a lot higher when subjects were really thinking about them working during hip extension exercises such as RDL’s hip thrusts, squats and back extensions.

Other muscles that were found to respond well to the mind-muscle link were the pecs and the triceps; focusing on the pecs while pressing limited the work the triceps had to do, placing more load through the pecs. This was easier to do when performing a push up rather than a bench press.

For puling muscles such as the back, mid-traps and the biceps it was really dependant on the movement being performed at the time. Lat activation didn’t change too much during a chin up, but they really came into play when thinking about them during an inverted row.

On the whole there is evidence to suggest there is a mind-muscle connection, and we should really think about muscles working if we want to improve the amount of work they’re contributing in a lift. However, there are a few other things to bear in mind:

1. The amount of weight being used – steering your thoughts to a muscle when using lighter weights seems to a lot easier to do than when lifting heavy weights (Snyder & Fry 2012), this may be why the push up trumped the bench press.

2. How experienced you are – as with anything, practice makes perfect. Typically, people who are new to training tend to have a poor bio-mechanical feedback, meaning they struggle to feel muscles working when performing an exercise. As your experience in the gym grows, so will your ability to start thinking and contracting your muscles during certain movements. This should then lead to better progression and recruitment! (Moreside JM et al. 2008)(Sumiaki Maeo, Takumi Takahashi et al. 2014). 

So there you have, and I personally believe the mind-muscle connection does exist as we see it day in and day out with our clients too. A great way I explain this to clients is to look at the connection like revising for an exam:

When you revise for an exam, it’s one thing reading the information you need to learn, but just because you’ve quickly read it doesn’t necessarily mean you’ve understood it or will even able to recite it. However, if you think about what you’re reading and really visualise it, then you’ll have a much greater understanding and retention rate – muscles are no different. Think about the muscle you’re trying to work and really hone in on it. I guarantee it’ll add a whole new dimension on to your training.

Next week I’ll be talking about how you can create this link between mind and muscle.

From eccentric and concentric training, to blood flow restriction and hamstring training, June’s fitness research has covered it all. Our level 4 trainer George has sifted through it all to bring you some gems you can apply to your own training straight away – enjoy!

1. Eccentric training beats concentric training – over a long time period
A recent meta-analysis study – which is the epitome of all studies and one we should definitely listen to – showed that with equal volume, eccentric-only training produced marginally greater increases than concentric-only training. Now, although the increase was relatively small, it would make sense that over time (I’m talking years) we’d likely see an exponential gap form between the two different methods.

As muscles are able to contract against more load during the eccentric, with less energy expenditure for an equal amount of mechanical tension (volume load), the eccentric proves to be of definite importance to any workout – especially hypertrophy and strength programs.

So what should you do with this information? Well, I’m certainly not advising removing concentric contractions. Both eccentric and concentric are essential elements in your training routine. They’re not even different methods, they’re just the two different phases of a rep, so make sure your training covers both. After all, it’s not likely that you’d ever perform just eccentric reps without the concentric – deadlifts would be off the cards!

2. The jury’s out on making bloodflow restriction comfortable
If you’ve ever done blood-flow-restriction (BFR) you’ll be able to recall how uncomfortable it can get! Can we get around this by applying the wraps post exercise, instead of during the set? Typically, wraps would be applied throughout the set to prevent the build-up of metabolites within the muscle from clearing, and then be kept on for an additional 60 seconds post-set.

A recent study tested out completing normal sets, then applying wraps for 5 minutes after the set (instead of while the contractions were taking place), against the same protocol but without post-set wrapping. Results showed that very similar outcomes were found across both groups.

From this study, it was concluded that the accumulation of metabolites isn’t the cause of an increase in muscle cross-sectional area (CSA), but that the BFR causes an increase in motor unit recruitment and that’s why an increased muscle CSA would occur. Taking this, and my previous point into account, seems that an increase in metabolites hasn’t been considered as a potential cause of increased CSA. As the wraps weren’t applied throughout the sets, I’d say that only applying the wrap at the end of the set would likely have allowed much of the metabolic waste to clear. After all, muscles don’t want to be full of metabolic waste, they want to get rid of it as fast as possible and are constantly flushing out that contractile by-product. They won’t be waiting until the last rep has been completed to begin this process.

There we are; as it stands the jury is still out on the exact BFR method to use.

3. Drop sets are best for size, multiple sets are best for strength
I have no idea who came up with the drop set phenomenon but it sure was a great idea, especially as it was likely done out of pure intuition and not backed by science! Numerous studies have shown the benefits of drop sets on muscle size, and here’s the freshest member to the club.

With total load lifted being evenly matched across two different groups, the drop set group increased overall muscle cross-sectional area (CSA) by 10%, beating the 5% in the normal, multiple set group. Although the difference seems minimal, again, added up overtime this could lead to the difference between 15” & 20” pythons!

But what about rep strength instead of size? Even though in this study, drop sets proved to increase muscle CSA by an extra 5% and indicators of fatigue were higher, rep strength didn’t increase. However, in the multiple set group it did. It’s likely that a huge component of this increase would be via metabolic stress (one of the primary mechanisms of hypertrophy) due to increased metabolite build-up within the muscle during the exercise. This decrease causes lower threshold fibres to work and at a higher number of reps, resulting in greater metabolic stress.

Mechanical tension still plays a huge role as another mechanism of hypertrophy and should be varied within your training programme using a phased approach – cycling between mechanical tension, muscle damage and metabolic stress.

Because the multiple set group completed the same total load using higher threshold fibres, greater mechanical tension would have been created therefore a greater increase in strength was observed.

4. The Nail in The Coffin for No Knee Over Toes? Finally!
I’d like to think that this old cliché is dying out and hope that June’s latest study will put it to bed for good. This study pitted ‘knees over the toes’ against its rival ‘knees not-over the toes’ – I guess you’d call it?

I’m not sure whether this study was designed to describe the sheer force created by a knee over the toe approach, but please bear in mind that ‘joint stress’ isn’t a bad thing at all. I’m sure if we exchanged it for ‘joint torque’, some heads would sure turn as it sounds much more conducive to strength and hypertrophy results. Torque is all we’re ever creating around joints when we lift something – from cup of tea to max effort squat – even though the torque values do vary greatly!

All in all, less knee flexion was shown to produce less joint torque (shocker). However, taking the squat for example, you might be able to squat 100kg by flexing to 100^o of knee flexion, and 120kg by flexing to only 80^o but you added load to the ‘shallower’ squat and would have most definitely still increased joint stress.

Throughout a training program less knee flexion would likely show decreased gains in the quadriceps’ strength and size due to reduced torque, and subsequent muscle stress throughout its entire contractile range.

Anyway, knees over toes is about as arbitrary a measurement I think you could find.

Assuming that the elbow is effectively the knee of the upper body – why haven’t we created an “elbow must not flex further than the hand” movement? Not so crazy, right? I’d like to add that nowhere in this study were exploding patella’s noted during any of the lifts.

5. Curl away for solid hamstrings!
No, unfortunately not bicep curls but Nordic Curls, an old-school hamstring exercise. Along the lines of our founder – Chris’s post in our Facebook Community page – one recent piece of research investigated the effect of eccentric hamstring training on total hamstring strength using two primary exercises, Nordic Curls and the Russian Belt.

Hamstring strain is common in many sports – especially football – and something we want to prevent, hence the need for building rock-solid hamstrings!

Eccentric loading alone of the hamstrings using Nordic Curls and Russian Belt exercises was shown to increase hamstring strength but interestingly, only the Nordic Curl seemed to improve asymmetrical imbalance between legs.

Most Personal Trainers will focus on the hamstrings’ function during hip extension and knee flexion, thinking only about the concentric phase. It’s important to remember their role in the opposite direction, when the hip is flexing and knee extending – acting as stabilizers of those joints. The hamstrings and calves work synergistically to provide stability across the knee, and therefore act like a force decelerator as the foot strikes the floor. Without this you’d have to kiss goodbye to your poor knees!

The biggest takeaway is that both exercises are eccentric loading exercises, therefore a protocol of eccentrically overloaded prone lying leg curls should display the same result. Muscles only response to muscle tension, they’re unaware of the actual exercise performed.

There we have it – curl away for immense hamstrings!

In April, I took another trip to Ben Pakulski’s Mi40 Gym in Florida. Mi40 is a world-famous facility specialising in hypertrophy, and I went specifically to increase my knowledge of exercise execution, selection and unsurprisingly push some mental boundaries when it comes to effort in the process.

I want to share a few thoughts about maximising hypertrophy gains that rubbed off on me during my trip, and the top three mistakes people make when it comes to hypertrophy training. Although there are loads of studies and theories about the best way to do this, it’s pretty hard to argue with some of the most mammoth human beings I’ve ever had the pleasure of meeting. Their theories must work, right? There’s always a perfect blend of science and application, and these guys have nailed it.

There are a few main points I want to cover in this blog post. Firstly, all the personal trainers at Mi40 are sticklers for technique. Now, I’m not talking about your typical “bar must touch the chest on bench press” kind of form; it’s a totally different level of technique critique!

Secondly, none of the exercises they use are special in any way; they are simply variations of basic exercises most gym-goers will have in their exercise library. All variation is done intelligently, with a proper thought process, as opposed to variation for variation’s sake, which is something we see far too often from some personal trainers!

Lastly, knowing how to apply focused effort is key to maximising your hypertrophy gains. I say ‘how’ because it seems there isn’t an inherent lack of work being done by most gym-goers, but the focus is often misdirected.

Mistake 1: Putting Periodisation Before Exercise Execution

The importance of exercise execution in training for hypertrophy that has been somewhat neglected by many in the fitness industry lately due to the arrival of the new kid on the block – periodisation.

Bold statement alert. There’s been a lot of discussion in the personal training industry recently about periodisation, and why it is the most important element of hypertrophy training. While there is definitely serious merit to a phased approach to training in everyone’s programme, it shouldn’t be made the determining factor of whether a programme is great or not. Linear, wave or pyramid – I don’t care! Put simply, each and every one of these are methods of altering total workload (volume) across a period of time.

If you ever hear claims of the perfect programme, please turn away from the personal trainer in question, and re-read this blog post. Essentially, you could have the most perfectly periodised training programme known to man, but I can guarantee that if your execution is off, you just might as well throw that plan in the bin!

Before you address periodisation; focusing on executing exercises correctly, and maintaining that perfect execution throughout your entire workout is unbelievably important. If you aim for perfection with each rep, you’ll be open to a greater margin for error within your training, allowing for greater hypertrophy gains.

Mistake 2: Random Exercise Selection

The second element is exercise selection. This is where things get interesting and seemingly unconventional. When it comes to hypertrophy:

• Yes – Free-weight exercises can be great exercises
• Yes – You’ll likely get bigger arms doing barbell skull crushers
• Yes – Chin-ups can build you a bigger back

However, the above exercises may not be your best options for maximum hypertrophy. Stick with me here. By being clever with our exercise selection, we can design more efficient and far superior workouts. Please put aside all prejudices about your favourite exercises and read the following statement carefully.

Essentially, the most effective exercise for a given muscle is one that has the ability to perfectly match the output capability of that muscle throughout its entire range of motion.

And to those who think we’re overcomplicating things here and reply – “But people have been getting big and strong by doing compound basics for years!” – Correct, they have. But, what if we never progressed our thinking? What if we still assumed that pigeon post was the most effective way of getting a message out? I have no idea how many pigeons I’d have to send in order for you all to read this…

There’s an entire plethora of fancy adaptations you can make to achieve a more optimal exercise resistance profile such as employing resistance bands, heavy chains & varying cable angles. Although throwing a resistance band on something may get you more looks in the gym it doesn’t always make the exercise more beneficial, in fact it could be making it worse! They must be used in the right way when it comes to hypertrophy, taking a lottery approach to your exercise selection isn’t likely to get you far. I’ll be doing another blog post on selecting optimal exercises shortly – keep your eyes peeled!

Mistake 3: Misplacing Your Efforts

So, effective execution and the correct exercise selection are crucial to a good hypertrophy programme, or workout. But we’re missing the third key ingredient – good old fashioned hard work.

We need all three elements – execution, selection and effort – present in order to elicit a maximal training response. In fact, we need execution and selection in place first to even qualify to use effort!

You see, most people complete 200% workouts using 50% reps, meaning they go mad for an hour with a tonne of unnecessary sets and flamboyant zero-resistance exercises. I’ll go all in and say that if we focused a little more on selecting more efficient exercises and squeezing the last drop out of every inch of each rep, you could easily cut your training volume and gym time in half. You’d even have more time for changing room selfies!

Look around, judging by the screwed-up faces and endless grunting, it’s not a lack of intensity that’s holding you back. I see 10/10 for effort but a modest 2 for concentrated focus and effort. Actual effort is what counts, it doesn’t matter how much effort it looks like you’re putting in.

The goal isn’t to “win” the workout. The goal is to progress, and enjoy yourself along the way. If you can get that done more effectively & in less time, then it would be foolish not to. Let’s be honest, nobody relishes in the thought of ten sets of Back Squats!

Please come back and tune in soon, when I’m going to lift the veil on ‘the 5 Factors of Optimal Exercise Selection.’

Hall Training Systems has rebranded to Hall Personal Training, and today unveiled its new logo, tagline and website to support its evolution over the last year.

The underlying ethos of the brand remains the same: we are still committed to providing the very best service to our clients, going above and beyond other personal trainers in Oxford. We are still committed to achieving results through science, but we blend the most up to date health and fitness theory with our years of industry experience, ensuring the best approach for each client as an individual. Finally, we still take a ‘systemised’ approach. Now this doesn’t mean cookie cutter programmes or nutrition – that is completely against what we stand for! For each individual we do everything from scratch, based on your individual goals, exercise history and the time available. But it means we have tools and systems that we know work, and processes we can employ to make sure our results are among the best in the industry, let alone in Oxford.

So, why the rebrand?

Well, when it was founded, Hall Training Systems was the brainchild of our founder, Chris. He loves practical application and science and information, and treating clients as individuals – and the old brand reflected that. But since then, the company has grown, and we now work with an amazing, hand-picked team of personal trainers across Oxford. When we got together to decide what makes us us and sets us apart, our truly personal approach for each individual client shone through. So we wanted to put the personal back into personal training, and back into our brand. We’ve kept the good of the old Hall Training, and made it better.

Now for the strapline…

“Results through science” has been replaced with “Stronger. Healthier. Happier.” Results through science is what we focus on as professionals, but it’s not why our clients come to us. We spoke to our awesome community and asked them to summarise why they wanted a personal trainer in the first place, and most importantly, what we’ve helped them achieve. Being stronger, healthier and happier people was the unanimous feedback we received, and what we, as a team, want our clients to feel when they work with us. From the comments that came back to us, it looks like we’re getting it right!
Finally, you’ll notice we have a shiny new website! We owe our thanks to the fantastic team at Rare Form New Media in Oxford for their help with this. We wanted something that reflected our vision for our clients, our ethos as a team (friendly and approachable, down to earth, but damn good at our jobs), and the fact that we work with people of all ages, abilities and backgrounds. Hopefully you agree that this is what we now have. We hope you enjoy exploring it!
