Training

There is a fundamental law that applies to many areas of life. It is as follows:
If you want more, you have to do more.
This principle seems to apply almost everywhere. You will get more in many areas if you invest more. Do you want to get ahead in business? Then work hard at it and you will have the best chance of success.
Do you want a more fulfilling relationship with friends and family? Then spend more time building that relationship. Do you want to be the best player on your team? Then train harder and longer than your competitors and you will slowly stand out from the crowd.
I think you know where I'm going with this. When training with weights, however, it's not quite so simple. The "more is better" approach only works up to a certain point...and then it stops working. At a certain point, more will even become counterproductive.
When it comes to building muscle, strength and endurance, more training is generally better than less training...but once you exceed your body's recovery capacity, things can quickly go south.
Here's a short list of what will happen next:
- You'll struggle to finish your workouts
- You will lose strength and endurance
- You will sleep poorly
- You will struggle with exhaustion and lethargy
- You will feel strange aches and pains
- You will get sick more often
These are all signs that there is a systemic imbalance between work and regeneration. Scientifically, this symptomology is known as 'overtraining syndrome' (1) and the likelihood is that you will struggle with this problem at some point in your fitness career.
This article can help you avoid this problem. You will learn how to recognize overtraining before it becomes a serious problem and what you can do to prevent overtraining in the first place. You will also learn what you can do if you have reached a state of overtraining.
First, let's start with the common (and often false) clichés about overtraining.
Is overtraining real?
If you've been training for any length of time, you'll probably have heard two things about overtraining:
1. "There is no such thing as overtraining. There is only insufficient recovery."
The underlying idea here is that people who are physically overwhelmed by their training sessions are not training that hard at all, but simply not recovering enough from their training.
2 "If you do more than 2 to 3 heavy weights and low intensity cardio workouts per week, you will inevitably end up in a state of overtraining."
This line of thinking is generally supported by the view that more than a few intense workouts per week will overload the central nervous system.
And if you've spent any time on either side of the debate, you've probably heard reasonable-sounding arguments for both positions. But as usual, the truth seems to lie somewhere in the middle (2).
Training heavy with weights puts a lot of stress on your muscles and central nervous system, but most people can train harder than they are right now without negative physical side effects
For example, consider a study conducted by scientists at the University of Sydney (3). The subjects were young men in their twenties and thirties who had at least two years of experience training with weights and were capable of doing an average of 155 kilos of squats.
Each of these subjects performed two upper body and two lower body training sessions per week, which corresponded to four training sessions with weights per week. For squats, the men were divided into three groups:
- Group 1 performed 1 set of squats to the point of muscle failure with 80% of 1RM weight.
- Group 2 performed 4 sets of this type.
- Group 3 performed 8 sets of this type.
After 6 weeks, all groups had increased in strength, with group 2 and 3 building significantly more strength than group 1 and group 3 showing the greatest strength gains. If you've ever done squats with 80% of your 1 RM weight (which is a repetition range of 5 to 7 reps), then you know how tough this training program was. One squat session of this type per week is demanding and two of them are downright grueling. And yet no signs of overtraining were observed.
An even better - and more extreme - example can be found in a study conducted by scientists at McMaster University (4). In this study, 40 young, overweight men were divided into two groups.
One of these groups was put on the following program:
- 40% calorie deficit
- High protein intake (2.4 grams per kilo)
- 6 training sessions with weights/HIIT training sessions per week
The other group did the same, but only ate half as much protein. If you showed this to most personal trainers, they would say you're crazy and that all you're going to achieve with this is muscle loss.
Well, after four weeks, the subjects in the high protein group had lost an average of 10.5 pounds of fat while gaining 2.5 pounds of muscle. The subjects in the lower-protein group had lost an average of 8 pounds of fat and gained no new muscle mass.
My point here is not that you should do 16 heavy sets of squats per week or maintain a massive calorie deficit with several hours of intense training per week. I just want to illustrate how much you can abuse some people's bodies before negative effects become visible.
Exactly how far you can go depends on many things, which include your age, genetic makeup, exercise history, diet and sleep hygiene, but I can promise you this: It's far harder to get into a state of overtraining than most people think.
I have worked with many exercisers and can say with absolute certainty that if you are a relatively healthy adult, you can do very well with something like the following:
- 3 to 6 hours of heavy training with weights per week (3 to 5 workouts)
- 1 to 2.5 hours of cardio per week (depending on your goals)
- 20 to 25% calorie deficit with a high protein diet and high carbohydrate intake
8 signs of overtraining you should know
It may be hard to get into a state of overtraining - and it may be more of a psychological state than a physical one - but it can happen. I had my first experience of this a long time ago while working with a personal trainer.
He had me doing workouts 6 days a week for 2 or more hours that took me well past the point of physical exhaustion - to the point of mental exhaustion. After 5 or 6 weeks of this ordeal, I was exhausted. I wasn't sleeping well, everything hurt and I could barely muster enough energy to finish my training sessions.
He advised me to take a week off training to recover and 7 days later I felt like I had come back from the dead. If I had known then what I know now, I could have spared myself the agony.
Overtraining doesn't happen overnight. It's like quicksand - it slowly pulls you down and the harder you fight it, the faster you sink. For this reason, I'd like to look at some of the signs of overtraining below to show you that it's time to take your foot off the gas (5).
1. your training sessions feel particularly heavy
When your body is exhausted, the perceived effort during training increases. This is to be expected if you've just finished a set, but if this becomes the norm, it could be an indication that your body needs a break (6).
2. you lack motivation to train
If you normally look forward to your training sessions but suddenly don't feel like going to the gym anymore, this is a red flag (7).
For me, it got so bad at some point that I was no longer able to finish my training sessions. I was so physically exhausted that I couldn't even force myself to try anymore.
3. you suffer from depression
For some people, the mood disturbance caused by overtraining goes far beyond training. They lose all motivation to do anything (8).
4. you suffer incessantly from sore muscles
Muscle soreness is a part of training with weights, but as you become more experienced, you will experience less and less muscle soreness regardless of what you do. (This is not a bad thing, by the way, as muscle soreness is not an indicator of muscle growth).
However, if you overdo it with your training, you may experience persistent muscle soreness that doesn't go away completely (9).
5. you are not sleeping well
If you push your body too hard, your nervous system can become overstimulated. This will make it harder for you to fall asleep and feel fully rested (10).
6. you are constantly tired
If you don't sleep well, you'll be tired. No surprise so far. However, if your body is constantly overworked, you may feel constantly tired and exhausted even when you do get enough sleep.
7. you feel strange pains
This is one of the first things I notice when it's time for a break. First my shoulders start to hurt, then my wrists and then my knees. These symptoms usually start after 8 to 10 weeks of intense training with weights and they go away after 3 to 5 days off.
(I should mention at this point, however, that joint pain can also be caused by other things such as poor exercise form or lack of flexibility).
8. you get sick more often than you normally would
Prolonged periods of intense training can suppress the function of the immune system, which will make you more susceptible to illness (11).
In the second part of this article, I will go into more detail about what you can do to avoid overtraining in the first place.

By Mike Matthews

The trick is to start with a high box and slowly reduce the height as your confidence increases. You should also be careful never to just drop onto the box, lose your body tension or do any of the other stupid shit I see everywhere online. The box is a tool, not a springboard. Sit down, hold the tension and maintain control.
Another way to do this is to use a power rack. Placing the safety pins slightly below the lowest position of the movement can give the exerciser the peace of mind they need to move the weight all the way down without fear of not being able to get back up.
Master the excitement
Understand that there is such a thing as too much arousal and too little arousal. Although not being ready to perform an exercise can obviously be a problem, being too aroused can be a huge energy drain, especially when you're under the bar.
Forget the excuses
Any exerciser who performs modestly on squats has a plethora of excuses for why they suck at squats. I don't have time for people like that. If you suck at squats, then annoy someone else with your excuses who might be interested - i.e. nobody. And if you hate squats, then don't train squats. Do something else - and preferably far away from me. Do you seriously think that anyone cares about your weak knees or your back problems? Every exerciser has problems they need to take care of. So go to the doctor and shut up.
Squat training is hard - accept it
There's no way around it: a set of squats with 10 to 15 reps will make you feel like your heart is about to explode. One repetition with your 1RM weight can make you see stars. There are no magic tricks that will make squats suddenly feel easy. Man up and get under the bar!
Here's something I've never understood. Squats are so problematic for so many exercisers and yet everyone will struggle with hard stool on the toilet at some point. And what do you do then? Take a deep breath, push yourself, push like crazy, get a bright red head and give it your all. If this doesn't work, then keep at it until you have completed your task. So most exercisers work harder on the toilet than in the squat rack.
Tip: Find your ideal squat stand
Most powerlifters are better off with a wide stance, but you need to use what's right for you. Here's your guide
By Dave Tate
Source: https://www.t-nation.com/training/tip-find-your-ideal-squat-stance
Proper squat technique is a complicated topic because there are so many different styles of execution that can work. For example, I advocate a wide stance, but this doesn't mean that this is the ideal style of exercise execution for every exerciser. So the first thing you should do is find the best stance for your physiology, injury history and goals.
Here are some criteria:
- If you suffer from shoulder problems, choose a medium to wide grip
- If you have a short back, then choose a medium to wide stance
- If you have a long torso, then choose a medium-wide stance (the longer the torso, the narrower the stance should be).
- If you have long legs and a long back, then choose a narrow to medium-wide stance
- If you have long legs and a short back, then congratulations - you can do squats any way you want
If you're using supportive equipment, a wider stance is obviously better as the equipment will support the hips. The reason I like wide squats so much is the efficiency. This way of performing the exercise shortens the distance the bar has to travel to reach the lowest point, which is important for powerlifting.
A good squat
Next, you need to do the right thing. A good squat looks like this:
- Body tension (from your hands on the bar to your feet on the floor)
- Arched back
- Chest up
- Elbows under the bar
- Tight upper back
- Belly is full of air. Breathe into your stomach and not your chest. Look in the mirror - does your chest rise when you inhale? If so, learn to draw the air into your stomach. The reason for this is as follows: if you draw air into your chest, what happens when you breathe out? Your chest falls and the bar drifts forward.
- Grip the bar as tightly as possible without feeling any discomfort in your biceps or shoulders.
- Load your hips first and then bend your knees. This increases gluteus and hamstring involvement.
- The knees move in line with the ankles.
More important than anything else is that you consciously pay attention to the path of the barbell. Seen from the side, the barbell should move straight down and straight up again, as if you had simply dropped it vertically. The bar should move along the line that describes a plumb line hanging vertically downwards. This is possible with any stance and depends 100% on how the trainee is built. If you are unsure whether your stance is correct for you, then start here.
However, it is very difficult to go from a narrow stance to a wide stance. It can take up to two years to relearn the movement and develop the necessary flexibility, especially if the exerciser is very tense. Many exercisers will give up and simply go back to their original stance and I can't even blame them. However, if the plumb test - vertical movement of the bar - reveals that you should use a wider stance, then you will never reach your full potential if you don't change your stance.
Watch your knees carefully. Some forward movement is fine (this is unavoidable with a medium-wide stance), but the knees should never go beyond the middle foot and should never move inwards or outwards if you don't want to tear ligaments or tendons.
You should also remember that if your knee moves forward, this will increase the distance you have to travel until your thighs are parallel to the ground. The most extreme example of this is Sisyphus squats - at the lowest point of the movement, your knees are almost on the floor. You're so damn far down, but your thighs aren't even close to being parallel to the floor. So you have to compensate for any forward movement of your knees with additional force.
Don't get me wrong, I like Olympic-style squats with a close stance. I think these are great looking squats and I know a lot of very strong men who do squats this way. However, the fact is this: For those for whom this works, it's because this is the right type of squat execution for them. Most powerlifters, on the other hand, would be far stronger if they used a wider stance.
Tip: Rethink your recovery days
For faster gains, perform some non-eccentric training on your training days. Here's why.
From TC Luoma
Source: https://www.t-nation.com/training/tip-re-think-your-recovery-days
No one makes progress by training. Instead, we make progress when we recover from training. Rest and sleep are essential, but too many people overdo the concept of recovery. Unless you've just run an ultra marathon with an Atlas Stone, you don't need to spend your non-training days mimicking a corpse on the sofa.
Instead, you should use active recovery techniques such as weight sled work, kettlebell swings, sledgehammer work, medicine ball throws or cycling uphill.
Training with weights involves both eccentric and concentric movements, but it is the eccentric movements (lowering the weight) that cause muscle damage and soreness and it is the eccentric activity that you need to recover from.
The best exercises for active recovery are non-eccentric or mainly non-eccentric movements. As such, you can perform them on your recovery days to increase your blood flow, which will improve your recovery and burn a few extra calories after a cheat meal on your recovery day that would otherwise be stored as fat.
You don't have to do these exercises on every single non-training day, but there's no reason not to do them twice a week and enjoy a completely non-training rest day. It could look like this, for example:
- Monday: Training
- Tuesday: Training
- Wednesday: Active regeneration
- Thursday: Training
- Friday: Training
- Saturday: Active regeneration
- Sunday: Completely training-free rest day
Tip: Perform motorcycle rowing for the latissimus
Vary your back training with two variations of this latissimus exercise
By Christian Thibaudeau
Source: https://www.t-nation.com/training/tip-do-the-motorcycle-row-for-lats
This exercise has become one of my favorite bodybuilding exercises for the back. It is quite simply second to none when it comes to focused latissimus dorsi development with a targeted emphasis on the lower part of the latissimus. This exercise is derived from Vince Gironda's Motorcycle Rowing.
The classic motorcycle row
(https://www.youtube.com/watch?v=i-9oVuWe1_s)
I prefer the same movement pattern, but with only one arm. The unilateral aspect of this exercise allows for greater activation of the high threshold motor units in the latissimus while allowing for a greater range of motion.
The angle of the trunk prevents the involvement of the rhomboids, which means that most of the effort is concentrated on the latissimus. The key aspect is to achieve a really good extension of the latissimus in the starting position and pull towards the hip with the elbow of the pulling arm.
Tip: Perform deadlifts for an increase in total body strength
This brutal deadlift variation will make you stronger for pull-ups, Olympic weightlifting exercises and more
By Christian Thibaudeau
Source: https://www.t-nation.com/training/tip-do-sweeping-deadlifts-for-overall-strength
I started using this exercise to teach my athletes to use their latissimus more in deadlifts and Olympic weightlifting exercises, but I quickly found that this variation can turn deadlifts into an even more comprehensive and complete exercise for the entire back.
Deadlift deadlift
Regular deadlifts work well for training the lower and middle back, as well as the trapezius. There is some latissimus involvement to keep the bar close to the body, but this is not enough to stimulate maximum growth.
By using a resistance band attached to the bar and an immovable object in front of your body, you can dramatically increase the force your latissimus needs to produce. This deadlift will help you build strength in all the muscles of your back. This is such a good exercise for building total body strength that it will even help you with your pull-ups.
Perform 4 to 6 sets of 4 repetitions. Use a weight that is about 70% of your maximum weight for deadlifts and go far enough back to feel good tension in the latissimus.
An even better exercise for the upper back and latissimus is the same exercise using another handle. Alternate between the two. Use about 15 to 20% less weight for the wide grip variation.
Tip: Train heavy lockouts to develop bigger triceps
For thick, strong triceps you need to train the lateral muscle head. Here's the best way to do this
By Christian Thibaudeau
Source: https://www.t-nation.com/training/tip-for-bigger-triceps-do-heavy-lockouts
The best way to increase the thickness of your triceps is to get the lateral muscle head of the triceps to grow. Heavy lockouts during pressing exercises are the key here.
Flat bench presses, reverse incline bench presses and shoulder presses are good choices for training in the lockout position (hyperextended elbow position). Place the safety pins of the rack in the power rack so that you can only move the barbell 20 to 25 centimetres during these exercises. The lateral muscle head of the triceps responds best to heavy weights and these are the exercises that allow you to load the triceps with the greatest resistance.

He will forever be known as the "Iron Guru". Learn more about Vince Gironda's old-school bodybuilding philosophies, nutritional recommendations and sample workouts!
If you're a fan of bodybuilding or physique competitions, then you may know that many of the top champions work with a trainer and/or nutritionist to help them prepare for their competitions.
Many of the people these athletes hire are known as coaches or "gurus". You may recognize the names of some of the top "gurus" of today, but there is one bodybuilding guru who could be considered the original.
He was the "Iron Guru" of the golden era of bodybuilding and worked with many champions of the time including the original Mr. Olympia, Larry Scott, Lou Ferrigno, Frank Zane, and even Arnold Schwarzenegger.
Who was Vince Gironda?
Vince Gironda was born in the Bronx in 1917 and moved to Los Angeles with his family after his father got a job as a stuntman. The young Vince originally wanted to follow in his father's footsteps, but then turned to training with weights after seeing a photo of the then famous bodybuilder John Grimek.
At the age of 22, Gironda began training at the local YMCA before moving on to train at the Easton brothers' gym. They taught him everything he needed to know to become a trainer. During this time, he took part in bodybuilding competitions himself.
Even though he never won a competition, in 1962 he came 2nd in the Mr. Universe competition with a body weight of just under 80 kilos. The spontaneous apprenticeship with the Eastons ended when Gironda decided to open his own gym in North Hollywood called "Vince's Gym".
During the fifties and sixties of the 20th century, his reputation as a trainer grew thanks to the aforementioned champions who won competitions and claimed to owe it to him. This led to him becoming a trainer to the stars, working with numerous Hollywood stars over the years including Clint Eastwood, Denzel Washington and Sean Penn.
The Vince Gironda training mindset
Gironda was one of the first to talk about the role of the mind when it came to developing the body. He made sure that all the people he trained didn't just focus on what they were physically doing during the workout. They also had to believe and trust that they could achieve the goals they had set for themselves.
How Vince Gironda shared his knowledge
In addition to his personal training, Gironda was also a talented author who wrote many articles on muscle building over the years that were read by many people across the country. Gironda's knowledge and passion when it came to training was shared by those who followed him until his death in 1997 - a month before his 80th birthday. While many of his ideas were originally published in the fifties and sixties and later ignored in favor of more modern discoveries, some of his principles are still propagated and continue to help many people today.
Vince Gironda's nutritional philosophies
Even though he was primarily known as the iron guru, Gironda also helped many people with their nutrition programs. His philosophy was that bodybuilding is 85% nutrition. Many consider Gironda to be ahead of his time, as he promoted low-carb diets long before they became popular.
He also promoted the use of nutritional supplements. The products he recommended included dried liver tablets, kelp tablets, digestive enzymes and glandular products.
Some of his dietary recommendations were controversial. Among his favorites were fertilized chicken eggs and cream. Other foods he recommended were based on the particular athlete and what he believed was needed. He did not have a one-size-fits-all approach to nutrition.
Principles that Vince Gironda rejected
Gironda was known almost as much for what he disliked as what he favored. Regardless of the athlete he was training, for example, he was totally against the use of anabolic steroids and he spoke out against their use throughout his career.
Other topics he spoke about included his exercise selection. Gironda's focus was primarily on bodybuilding and body development and his exercise selection reflected this.
For example, he was not a fan of squats. As a result, there was no squat rack in his gym. Gironda believed that squats train the gluteus and hips, which can affect their proportions compared to the thighs. He occasionally made an exception for women who competed and, in his opinion, had deficits in these areas. Otherwise, he recommended leg extensions, leg curls and other exercises that isolate the quadriceps and hamstrings.
He was also against sit-ups and was among the first to criticize this exercise as one that doesn't really target the abs.
Bench press to the neck and Gironda dips
Another exercise that Gironda disliked was barbell flat bench presses. He felt that this exercise recruited the front shoulder muscles too much, which to him meant that it wouldn't help the chest. Instead, he developed and promoted the Gironda bench press to the neck. This variation of the bench press uses a wide grip and the exerciser lowers the weight to the lower part of the neck instead of the chest.
Another exercise he modified according to his preferences was classic dips. His Gironda dips had the exerciser looking down and the chin touching the chest. The hands are positioned so that the fingers are inside the handles. The elbows are extended and the legs are stretched forward instead of being bent under the body. Gironda felt that performing dips in this manner would isolate the pectoral muscles and minimize triceps involvement.
Vince Gironda's "honest" training programs
Although Gironda's contributions to the world of fitness and bodybuilding were numerous, there is one that still stands out from the rest decades later. His 8 x 8 program has been referred to as his "honest" training program, as it encouraged exercisers to use lighter weights and focus on making the muscles work rather than focusing on the weight used. This principle has also been referred to in recent years as high density training.
In this program, 8 sets of 8 repetitions are performed and the rests between sets last only 30 seconds. It is impossible to do this with heavier weights without sacrificing the correct form of the exercise, which Gironda strongly opposed. He believed that using lighter weights and shorter rests would maximize muscle fiber growth and help burn as many calories as possible in the shortest amount of time possible.
There were two different ways to train with the 8 x 8 method. You could either use a full body training program or focus on individual muscle groups, as is the case with a bodybuilding split program. Both options were intense and you could be sure afterwards that you had done a serious training session.
If you use the full-body training program, you should limit yourself to a maximum of 5 exercises. Even if this is only 8 sets for each major muscle group, this is a total of 40 sets per training session.

Having discussed the phenomenon of sarcoplasmic hypertrophy in more detail in the first two parts of this article series and looked at a number of studies and mechanisms that may be associated with sarcoplasmic hypertrophy, in this final part of this article series I will summarize the current state of research and, in the appendix, discuss more recent findings that have emerged since the original article was completed.
What about steroids?
One more thing before we get to the summary: I know I'm going to get some questions about steroids. Do they contribute to sarcoplasmic hypertrophy?
Bro wisdom says yes. A lot of people report gaining weight quickly when they start using steroids (more weight than could be explained by just myofibrillar hypertrophy) and that they also lose this weight very quickly when they stop using these substances, probably indicating shifts in the amounts of water their body is storing.
However, it is not always obvious that this water is stored in the muscles themselves (some users report that their muscles feel 'fuller', while others perceive this phenomenon more as a bloated feeling) and the two studies that have looked at this issue so far have reported no increase in intramuscular water (32, 33).
However, dosing may be an issue here: The dosages used by exercisers in the real world are rarely used in scientific studies for ethical reasons. In the MacDougall study, sarcoplasmic volume relative to muscle fiber volume was much higher in the elite strength athletes (most of whom used steroids) compared to the "normal" study participants.
On the other hand, in the single muscle fiber studies comparing bodybuilders with power athletes and untrained control group members, no significant differences were observed between the muscle fibers of bodybuilders who reported steroid use and the muscle fibers of bodybuilders who reported no steroid use.
However, in one study, steroid-free strength athletes were able to produce almost 50% more force per unit of quadriceps muscle mass than bodybuilders who used steroids (34) (although training differences are also likely to have played a role).
In other words, it's hard to say what role steroids play, if any.
Let's summarize everything:
- Sarcoplasmic hypertrophy has never been measured convincingly in humans - at least not by the standards that would convince me personally. One study showed an increase in intracellular water after exercise, but the overall hypertrophy observed in this study was very small, so I wouldn't put too much faith in these results. Another study was able to show a low degree of sarcoplasmic hypertrophy combined with very robust overall hypertrophy after six months of training, but due to the very low degree of sarcoplasmic hypertrophy measured, I would not place too much confidence in this study either. The elite strength athletes in this study had more sarcoplasmic volume relative to muscle volume, but since they were not involved in any intervention, it is impossible to know if these differences were due to training or pre-existing differences.
- Although undissolved non-protein components in muscle (such as glycogen) could potentially contribute slightly to sarcoplasmic hypertrophy, any effect would be small and temporary. An increase in the proportion of sarcoplasmic proteins relative to the amount of myofibrillar protein would be more likely to be the cause if sarcoplasmic hypertrophy were to occur.
- We know that sarcoplasmic protein synthesis and sarcoplasmic protein degradation are not directly related to myofibrillar protein synthesis and myofibrillar protein degradation and that in mammalian muscle, although a 3:1 ratio of myofibrillar to sarcoplasmic protein is typical, a 1:1 ratio has also been observed (albeit only in medium aged rabbits) with no apparent adverse effects.
- The maximum force of individual muscle fibers is more closely related to muscle fiber diameter than to muscle fiber cross-sectional area. In general, as the cross-sectional area increases, the force relative to the cross-sectional area decreases. Without alternative explanations (all of which are unlikely under most circumstances in healthy young men - things like accumulation of inorganic phosphates and post-translational modifications of contractile proteins), the most obvious reason for this decrease is a decrease in myofibrillar density - i.e. sarcoplasmic hypertrophy.
- Although the picture painted by the currently available scientific literature is blurred, it appears that strength training maintains the relationship between strength and cross-sectional area as muscle fibers grow. And it could be that this is not the case with bodybuilding style training. However, some of the studies that showed increased strength per muscle cross-sectional area used lighter weights (60% of 1RM) and one study even showed that bodybuilders' quadriceps torque relative to muscle cross-sectional area was higher than that of powerlifters.
- It could also be that the likelihood of sarcoplasmic hypertrophy increases as muscle fibers become significantly larger. As muscle fibers grow, capillary density decreases relative to muscle fiber cross-sectional area and mitochondrial density also decreases, causing the muscle to rely more on anaerobic metabolism, which is carried out by sarcoplasmic proteins. Even in elite powerlifters, it was more muscle thickness that correlated very closely with strength (although this study did not measure muscle fiber cross-sectional area, it may have shown an equally strong correlation).
- Based on the currently available data with highly trained subjects, there are too many potentially confounding factors to say whether different training styles increase the likelihood of sarcoplasmic hypertrophy. In vivo measurements are influenced by muscle insertion points, muscle activation, cocontractions of antagonistic muscles, motivation, muscle lever arm, muscle flexion angle, etc. So far, most of the direct comparisons we have are in vivo comparisons, which means that there are not many studies at the level of individual muscle fibers from which we could see what is going on at the cellular level (which is the level to look at if you want to study sarcoplasmic hypertrophy). The only study that has compared muscle fibers of bodybuilders and power athletes seems to indicate sarcoplasmic hypertrophy in the bodybuilders, but this could also be related to innate differences that are independent of training or how much larger the muscle fibers of bodybuilders are.
I have to admit that I'm ending this article with a different opinion than I started it with. About 5 days ago I was sure that sarcoplasmic hypertrophy was either a myth or at best played a trivial role in muscle hypertrophy. Now I'm pretty sure that sarcoplasmic hypertrophy is happening, and while I'm still not completely convinced, I'm now much more open to the idea that it has a significant effect on overall muscle growth.
I remain skeptical when it comes to whether training in a specific way can either minimize the "risk" of sarcoplasmic hypertrophy (from a powerlifter's perspective) or increase the chance of sarcoplasmic hypertrophy (from a bodybuilder's perspective), but I am open to the idea that this may be possible.
Ultimately, this is a question that can't be answered conclusively until we have more high-quality studies on individual muscle fibers (or until a few brave souls are willing to donate a cubic centimeter of their muscles to science).
People with a wealth of knowledge on the subject of muscle physiology can be found on both sides of the debate. Dr. Stuart Phillips (35) and Dr. Anders Nedergaard (36) believe that sarcoplasmic hypertrophy is nonsense, while Dr. Brad Schoenfeld (37) believes that it occurs but plays only a small role in overall muscle growth and Lyle McDonald (38) seems convinced that sarcoplasmic hypertrophy does occur and can play a significant role in muscle growth.
I hope that this article has at least given the reader a better understanding of this topic and raised some questions that not every reader would have thought of.
Addendum, June 2017
A study published in 2007 by Cribb et al (39) adds another aspect to this discussion. I had overlooked this study in my original search as it was more of a supplement study (looking at the effects of creatine and whey protein) than a muscle physiology study.
The study participants were recreational bodybuilders who had a reasonable amount of training experience - the average performance at the start of the study was 100 kilos. These subjects were divided into four groups:
- One group supplemented with carbohydrates
- One group supplemented with carbohydrates and creatine
- One group supplemented with whey protein
- One group supplemented with whey protein and creatine
All subjects trained for 11 weeks with a Max-OT program.
The study examined (among other things) the muscle content of contractile proteins: the amount of contractile protein per unit mass. If the contractile protein content increases, then this is an indication of relative myofibrillar hypertrophy, while a reduction would be an indication of relative sarcoplasmic hypertrophy.
The groups taking whey protein and/or creatine showed greater increases in contractile protein content than the group supplementing carbohydrate alone (p<0.05). In addition, the two groups using creatine tended to have greater increases in contractile protein than the group using only whey protein (p=0.07-0.08).
But there are two other interesting notes to this study:
Increases in contractile protein content were independent of increases in 1RM weight during squats, and increases in contractile protein content correlated strongly with hypertrophy of all three primary muscle fiber types. This means that myofibrillar hypertrophy was the primary cause of overall muscle fiber hypertrophy in this study.
It is also worth mentioning that the changes in contractile protein content were quite small: up to 40 mg/g. This means that the proportion of muscle fiber weight consisting of contractile proteins had increased by a maximum of 4%. However, although this is a relatively small increase, it contrasts with the MacDougall study, which observed a small reduction in contractile protein content during exercise.
This may give us an indication that training style may actually influence the ratio of sarcoplasmic to myofibrillar hypertrophy. The subjects in the Cribb study trained with sets of 4 to 6 repetitions, while the subjects in the MacDougall study trained with sets of 8 to 10 repetitions.
However, it is always uncertain to make comparisons between studies, so this certainly cannot be taken as evidence that training style affects the ratio of sarcoplasmic to myofibrillar hypertrophy.
In addition, a study by Moore et. Al. found that even though protein consumption affects both myofibrillar and sarcoplasmic protein synthesis, strength training (10 sets of 8 to 10 RM weights) only affects myofibrillar protein synthesis (40). However, the question of training style remains unanswered, as the sarcoplasmic protein synthesis response could have been different with a different training intervention.
Lastly, this is a good study to share with people who claim that creatine only causes muscle growth (i.e. sarcoplasmic hypertrophy) via an increase in water content in the muscles. The groups that used creatine in this study had the greatest increase in contractile protein content - and even when the water content of the muscles had increased, it was outweighed by the observed increase in contractile protein content.
Addendum, January 2018
A recent meta-analysis by Schoenfeld et al. that looked at the effects of training load on hypertrophy, dynamic strength and isometric strength helps to refute one of the main arguments used by people to prove that light training with high repetitions causes sarcoplasmic hypertrophy. These people claim that because strength gains are greater with heavier training, heavy training must build more contractile protein (myofibrillar hypertrophy), while lighter training must increase muscle mass without building as much contractile protein (sarcoplasmic hypertrophy). I have already described earlier in this article why this is not a completely logical argument, but this meta-analysis gives us more direct evidence to refute this.
Unsurprisingly, this meta-analysis also concluded that heavy training is better for dynamic strength. However, there is a technical component to dynamic strength and heavier training helps to train these technical skills. On the other hand, there was no significant difference between high load and low load training for gains in isometric strength (i.e. a strength release where virtually no technical component comes into play).
This suggests that low training load builds contractile proteins just as effectively as high load training - low training load training is simply not as good a training for how to effectively use these contractile proteins for maximal dynamic contractions (e.g. maximal attempts).

Earlier this week, I was fortunate enough to spend some quality time with a friend of mine who recently completed his training as a physiotherapist. As we discussed the relative merits of different training protocols, my friend lamented that people in his profession rely too heavily on standard protocols for rehab training their patients. In his view, many physical therapists tend to prescribe programs of 3 sets of 10 repetitions to their patients regardless of training experience, age and personal preference.
My friend has been strength training for about a decade, which may explain his enthusiasm for varying repetition ranges for different populations. Over the course of their training careers, exercisers use 5 x 5, 3 x 8, 1 x 20 and a variety of other set and repetition schemes. For this reason, they know the effects that different training protocols can have. But even outside the world of physiotherapy, it is common to see exercisers following certain training protocols with almost religious fervor. When was the last time you heard anyone promote a program with 4 sets of 11 repetitions? That would be sacrilege...repetition ranges must be divisible by 2 for the vast majority of exercisers!
In fact, it's not just the world of physiotherapy that has fallen in love with 3 sets of 10 repetitions. Many programs for beginners and advanced exercisers also propagate this scheme. When I completed my first "real" 5 x 5 program, I was encouraged by older exercisers to move to a 3 x 10 program as an introduction to bodybuilding. With that in mind, in this article I'd like to explore the history of the 3 x 10 training program - a training protocol favored by many exercisers and physical therapists alike.
In search of the founder...
In my articles, I regularly deal with the fact that exercisers take conventional wisdom in the field of weight training and bodybuilding for granted without questioning it. Barbell squats appear to be a timeless exercise, but if you take a closer look at their history, you will see that they only appeared on the scene in the early twentieth century. The same applies to the traditional bench press. Our basic exercises are actually quite modern. The same is true for a 3-set, 10-rep workout - a training protocol popularized during the late 1940s and early 1950s.
However, our story begins in the early decades of the 20th century with a boy from Alabama who was born in 1917. Thomas Lanier DeLorme experienced a number of adversities during his formative years. He struggled with the poverty of the "Great Depression" years and a nasty bout of rheumatic fever. His youthful body was therefore quite fragile. Although he eventually reached a height of over 180 centimeters, DeLorme was confined to bed for four months during his teenage years to aid his recovery from a fever that had slimmed him down to 63 kilos. As reported by ranking physical culture elders Jan and Terry Todd, DeLorme used his time to study both medicine and muscle building.
Initially, DeLorme chose to study medicine because he wanted to help others who needed help. This selfless goal was accompanied by his second decision to not only rebuild his body, but to improve his physical development as well. Therefore, this young man spent his time flipping back and forth between medical textbooks and issues of Strength&Health - a strange, but admittedly profitable combination. In 1939, DeLorme was accepted to the University of Alabama for medical school. From there, he went to New York to continue his studies and change the world of mucoskeletal rehabilitation.
The war, weightlifting and Watkins...the experiments begin
Once in New York, DeLorme was contacted by a sergeant named Walter Easley, who wanted to discuss his recent knee surgery with DeLorme. After being told by doctors that his knee would never fully recover, Easley sought out the young man from Alabama in his search for help. Easley had followed instructions to do light training for his rehabilitation with almost religious fervor. Such advice was backed up by leading American physiotherapist R. Tait McKenzie, who believed that heavy training was counterproductive on the road to recovery. This advice was followed by many physiotherapists. But DeLorme was not one of them.
Instead, DeLorme advised Easley to use the maximum amount of weight with which he could perform as many repetitions as possible. Using iron shoes, Easley performed up to 70 repetitions of leg extensions per leg. This was an unorthodox approach that resulted in near-complete rehabilitation. As news of Easley's rehabilitation spread, DeLorme's reputation and notoriety increased. Other members of the Army began to follow DeLorme's advice, which promoted heavy resistance training.
Fortunately for DeLorme - and unfortunately for his patients - the United States was in the midst of World War II when DeLorme's career in rehabilitation began. This meant an almost endless supply of soldiers looking for help rehabilitating and healing damaged ligaments, bones and stress fractures. These were the perfect subjects for DeLorme's theories. DeLorme soon joined the Army with Dr. Arthur Watkins, who held similar views, and these two men began to make history.
In 1945, DeLorme wrote a paper entitled "Restoration of muscle power by heavy-resistance exercises," which was published in the Journal of Bone and Joint Surgery. Using 300 case studies, he observed an excellent response in muscle hypertrophy and strength combined with an improvement in symptoms when patients followed his method of 7 to 10 sets of 10 repetitions. The exercisers started with a relatively light weight and increased it until they reached their maximum weight for 10 repetitions.
In 1948 and again in 1951, DeLorme and Watkins changed their views as experience had shown that this volume was too high and in most cases 20 to 30 total repetitions led to better results. Fewer repetitions allowed training with heavier weights, which led to stronger and faster muscle hypertrophy.
Training with progressive resistance: 3 x 10 Magnum Opus
DeLorme and Watkins therefore began to promote fewer repetitions and a focus on heavier weights instead. They did this using scientific studies. Studies that were more replicable than the advice of the muscular guy in the gym. Along with several other authors, the two wrote the scientific treatise Progressive Resistance Exercise, a medical textbook published in 1951 and one of the first large-scale exercise books of the era. This book was in many ways a starting point for exercise science.
Frustratingly, I owned a copy of this book, but unfortunately it was lost when I moved house. Such is life... But thanks to the excellent Dave Draper Forum(https://www.davedraper.com/fusionbb/showtopic.php?tid/21871/ ) we can find some excerpts of this book on the internet without buying a new copy.
On the speed of repetition:
"The development and release of tension should be smooth and without pause at the highest or lowest point of the movement. The weight should neither be moved ballistically upwards with momentum nor dropped downwards under the influence of gravity."
On the number of repetitions:
"The number of contractions per repetition is arbitrarily set at 10. If fewer repetitions were necessary, the weight could be increased. Whether 10 is the optimal number for rapid gains in strength has never been determined by any criteria other than empirical experience of exercisers. However, it is probably the number that is close to the optimum."
On the duration of rests between sets:
"The length of rest intervals between bouts is important only insofar as it affects the total work that can be performed during a treatment phase. Short rest intervals are likely to reduce the number of repetitions that can be performed with the prescribed number of repetitions of 10. All existing data tends to suggest that prolonged training is not the primary prerequisite for increasing strength. Strength development - the amount of work performed within a unit of time - is important. A short but intense effort is the goal that should always be kept in mind."
On warming up/increasing weight from set to set:
"The increased temperature within the muscle is believed to affect the viscous and elastic properties of the contractile tissue in a way that increases the work performed during the same energy production, based on an acceleration of the chemical processes involved.
By initially using light weights and increasing the weight after each set of 10 repetitions, the muscle is warmed up and prepared to release its maximum force for 10 repetitions...
Performing only 10 repetitions with the 10RM weight would result in roughly the same strength gains as performing 3 sets. If it were not necessary to physiologically prepare the muscle for a maximum effort, then one set of 10 repetitions would be sufficient.
This has been demonstrated time and time again in the clinical treatment of injuries in young athletes... As amazing as it may seem, many athletes have developed great strength by never performing more than 5 repetitions of a single exercise. The amount of weight moved appears to be the key factor in stimulating hypertrophy.
Some scientists believe that it is the amount of work performed in a unit of time that is responsible for strength. Although not conclusive, observations suggest that it is the tension that the muscle has to develop that is largely - if not exclusively - responsible for stimulating hypertrophy and increasing strength.
The warm-up should not interfere with performing 10 repetitions with the 10RM weight. In other words, if the patient is too fatigued to perform 10 repetitions with the 10RM weight after performing the first 10 repetitions with the first weight (50% of the 10RM weight) and 10 repetitions with the second weight (75% of the 10RM weight), only 5 repetitions should be performed on the first two sets so that the patient is fresher and more rested for the 10 repetitions with the 10RM weight.
Another option is to skip the middle set of 10 repetitions (75% of the 1RM weight) and go straight to 10 repetitions with the 10RM weight after the first set of 10 repetitions with 50% of the 10RM weight.
Patients are regularly unable to perform 10 repetitions with the 10RM weight if they have not previously performed a set with a lighter weight."
On the training effect on the muscle:
"An increase in strength is accompanied by a measurable increase in size, which is attributable to hypertrophy of pre-existing muscle fibers rather than hyperplasia. The amount of connective tissue also increases and the sarcolemma becomes thicker. There is an increase in the number of capillaries and the content of muscle hemoglobin, phosphocreatine and glycogen increases. The net effect of these changes is an increase in endurance, which is sometimes impressive."
On the optimal number of total repetitions:
"In the first publications dealing with progressive resistance training, 70 to 100 repetitions were advocated, with these repetitions performed as part of 7 to 10 sets of 10 repetitions. Further experience has shown that this number is too high and that in most cases 20 to 30 total repetitions provide far more satisfactory results. Fewer repetitions allow training with heavy weights and lead to stronger and faster muscle hypertrophy."
Perform three sets of 10 repetitions. On the first set, use 50% of your maximum weight for 10 reps. Use 75% of your maximum weight for 10 reps on the second set and use 100% of your 10RM weight on the last set.
An explanation for the popularity of this training protocol
For physical therapists, the appeal of this program is easy to explain. DeLorme and Watkins had provided replicable evidence that this program helps build muscle and make patients more flexible and stronger. This was scientific evidence at its best. In addition, this program was easy to explain to patients and short enough to ensure compliance.
Whether the modern physiotherapists my friend referred to actually follow these protocols to the letter is another matter. It seems that many simply recommend 3 sets of 10 reps, with no emphasis on progressively heavier weights. However, this is a completely different story for another day and is no doubt influenced by the fact that for some strange reason, not everyone has the ability or interest to go to a gym.
When it comes to bodybuilders, the appeal of this approach is a little harder to pin down. While DeLorme and Watkins were primarily targeting the medical community, their interest in training brought them into contact with the world of bodybuilding and strength training. In fact, in the 1940s, DeLorme was known to be in contact with the likes of John Farbotnik, the 1950 Mr. America.
There is also speculation that bodybuilder George Eiferman knew DeLorme, although this is harder to pin down. The truth may in fact be that DeLorme and Watkins had simply found the scientific rationale for a training protocol that had been used before in the field of bodybuilding. Certainly the old Bob Hoffman courses already propagated 10 to 15 repetitions.
What was probably new about the DeLorme and Watkins approach was the recommendations on the weights used (i.e. 50%, 75% and 100%). The longevity and popularity of their protocols could be attributed to the fact that they are effective. This is something that anyone who has tried them will tell you and for this reason, this approach is still being promoted by modern trainers.
