Optimal training volume for muscle growth

If you’ve been involved in the fitness industry in some way for the last couple of years, you’ll have noticed that there is a never ending discussion going on between two die hard camps regarding training volume. These two camps are the low volume training group versus the high volume training group. Training volume has been a hotly debated topic for pretty much the last couple of 50 years. Back in the day, when physical culture was just getting started, in the bronze era of bodybuilding, where Eugen Sandow, George Hackenschmidt and Arthur Saxon were world famous celebrities, a lower volume approach with a higher training frequency was the norm. This went on during the Silver era, with figures such as Steve Reeves promoting full body workouts performed three times per week with moderate training volumes. It wasn’t till the days when Arnold Schwarzenegger and co. dominated the fitness industry that high volume training became a thing. Through the sands of time, recommendations for training volume have changed depending on who you’d ask. But what does modern research say? What can we learn from the past and how can we combine that with wisdom from the present?

Before answering this question I want to make sure we are all on the same page when it comes to the definition of training volume. Volume refers to the amount of sets performed close to failure ( less than 3 reps of failure) per muscle group per week. Recent scientific research has taught us that in order to gain muscle mass optimally, one needs to perform between 9 and 20 sets per muscle group, per week. Obviously, there’s a massive difference between a routine involving 9 sets per week and almost the double amount of sets, 20 per week. Allow me to guide you properly when it comes to choosing the right amount of training volume for your goals.

Training volume isn’t a black and white thing where one is necessarily better than the other. There are a couple of important factors that come into play when making a decision what’s right for you.

In the beginnings: the beginner to intermediate phase

When you’re just new to the gym, or you’ve been in the gym for a couple of months or even years not knowing what you’re doing and missing out on a lot of muscle gains, you’re better off starting with a lower amount of training volume. When you haven’t gained a lot of your muscular potential yet, it doesn’t take much to gain muscle at an optimal rate and you’ll only need the minimum dose of effective volume to start growing. Therefore I’d advise you to start your training career with performing 9 sets per muscle group per week. Doing too much volume as a beginner actually hinder your gains, since your ability to recover properly will be compromised due to excessive tissue damage and your body not being able to handle all that damage properly. People automatically think that more is better, but believe me, that’s not the case. With increased volumes comes increased fatigue, joint and tendon stress. You should gradually work your way up to building a strong muscular and neurological foundation where step by step, you build up your work tolerance and recovery in regard to lifting weights.

Once you’ve made significant gains in both strength and muscular size, there will come a time where about everyone is going to hit a plateau. Hitting a plateau means that even though you consume enough protein and calories, you’re consistent with your training routine and your lifestyle (sleep, stress, etc.) is on point, you don’t seem to make any more strength and muscle gains. If you’ve made significant gains already and your lifts are respectable, this might be the time where your body needs more volume in order to stimulate new strength gains and muscle growth. It’s best to add in additional volume gradually to monitor your progress.

For example: when you normally perform 3 sets of chest work per workout, 3 times per week, you’re performing a total of 9 sets per week. By adding one set each workout, we up that volume to 12 sets per week. From there, see what happens and monitor even further. The stronger and more advanced you are, the more volume you need to keep making progress. Eventually you can add another set which will lead to you performing 15 sets per week.

Talking about 9 to 15 sets per week… This is the range where most lifters will spend the majority of their training career. If your goal is to have an amazing physique without living your life in the gym, 9 to 15 sets per week will be the sweet spot of the volume recommendations for you. This range allows itself to perfectly fit the lives of people who are only able to make it 2-4 times to the gym per week , allows you to adequately recover even during periods of other stressors in life and is a propriate amount of volume to be sustainable in the long term so you don’t burn out so that you are able to stick to your training routine and stay strong, lean and athletic for the rest of your life. Depending on whether you are on a higher calorie muscle gaining phase or a lower calorie cutting phase, your volume will fluctuate to the higher or lower end of the 9 to 15 rep range to match your recovery abilities. Since you only need 1/3rd of the volume you used to maintain the muscle mass you’ve built, it should be used to strategically to your advantage in terms of recovery.

So if we will spend the majority of our time training in the 9 to 15 sets per week range, when and why should we train with high volume using between 15 and 20 sets per week? What advantage does it have and how should we use it?

Enter high volume specialization phases

When you’re about to graduate from the intermediate to the advanced stage, you’ll most likely benefit from performing incorporating periods of higher volume in your routine. Implementing higher volume will squeeze out those last bits of additional muscle mass you’re able to pack on your frame. However, if we were to perform a very high amount of volume for each and every muscle in the body at the same time, all the time, most people would most likely burn out after a while and feel like a total mess from the excessive wear and tear. Training takes a toll on your body. Recovery is an extremely important aspect of training and gaining muscle. If recovery isn’t on point, your lifts will  even go down and you’ll actually end up sabotaging yourself.

To make sure we can maximize our potential without the negative side effects of burning ourselves out, we should use high volume specialization phases. These are periods of time – around 3 months – where you target one or two muscle groups and train them with a higher weekly training volume compared to other muscle groups. You will have to gradually work your way up to the top range of the high volume recommendations for the chosen muscle groups, while simultaneously performing the minimum amount of volume to maintain or slowly make strength and muscle gains for the other muscle groups which aren’t being specialized. This is a fantastic method to bring up certain lagging body parts or just to make certain body parts stand out.

For example, let’s say you want to focus on maximizing your chest and back size, while maintaining or slowly gaining muscle and strength in your other muscle groups. In this case we would slowly work our way up to about 18 to 20 sets per week for our chest and back musculature. At the same time, we’d only perform 9 to 12 sets for the remaining muscle groups. As I’ve mentioned before, maintaining muscle is way easier than gaining muscle. Studies have shown that for us to maintain our muscle mass, we only need to perform 1/3rd of the volume we used to build our muscle mass. This means that if you’re coming off a high volume specialization phase for a certain muscle group, you can turn down the volume significantly and maintain every bit of muscle you’ve gained, while making room for a high volume specialization phase for another group.

I’ve found that when starting a high volume specialization phase, it works best when either specializing on either one or at the most two muscle groups at a time. Taking this approach will be time efficient and be favorable for fatigue and recovery reasons.

If you do want to combine two muscle groups per time, these combinations are my recommendations:

Back and chest

● Shoulders and calves

● Legs (quads, hamstrings, glutes)

● Arms (triceps and biceps)

Each phase last around 3 months. Once the 3 months are completed you have the option to continue what you’re doing for a couple of weeks more or you can reduce the volume back to 9 – 12 sets to simply maintain what you’ve gained during the higher volume phase. If you then want to focus on specializing a different muscle group, start a new higher volume phase for a new muscle group (or two muscle groups) of choice.

However, let me stress that high volume specialization phases are the cherry on the cake. You can’t put the cherry on the cake is there is no cake yet. Therefore, don’t rush the process. Take your time to build up a solid foundation. The 9 to 15 set per week range is where you’ll spend the majority of your time as a natural lifter. This will allow you to progress optimally and stick to your routine in the long term. After all, consistency is key. Someone who lifts for 10 years with a lower to moderate volume approach will have an amazing body. Somebody who trains sporadically with extremely high volume will have nothing to show for. The most important factor in resistance training is progressive overload. Progressive overload means becoming stronger over time and being able to handle higher workloads. This process takes time and can’t be rushed. The high volume specialization phases are just a tool in the toolbox to squeeze out muscular size after a certain experience level, but can only be maintained for a certain amount of time before taking a toll on the body. Therefore, train wisely, respect your body and I can reassure you that if you gradually get stronger over time, spending the majority of your time fluctuating in the 9 to 15 sets per week range depending on whether you’re on a bulking or cutting phase, your physique will look amazing. Once you’ve been consistent for a couple of years, you can make use of higher volume specialization phases and finally put the cherry on the cake.
