Hello guys.
This sub is one of the first places where I started my journey with workouts in general. People here were very helpful, I've learnt a lot from them. I wanna say thank you and now it's my turn to share with you my experience. I've learnt a lot since then, read a lot of researches, because that's the main source that I'm learning from.
I'd like to start a series of posts about... everything related with muscle and strength building etc. Everything is based on science literature.
I leave a link to my instagram at the end of the post. You can find there this post with pics. I'll be grateful if you give me a like, follow and share it with friends
I hope that I won't be banned because of that.
TL;DR + summary at the end
Minimum and the best number of sets for noticeable results
Do more sets will always mean better results? Is there a maximum number of sets per workout/week? How to choose the right number of sets if our goal is muscle growth?
Many people find it difficult to choose the right number of sets. It used to be difficult for me as well. First let's find out what factors affect the number of sets.
*This is a bit simplified and assumes that the rest of things remain the same and the only variable is the issue being described.
1.Number of workouts per week. Example: we've got 3 workouts per week, on each of them we do 4 sets of push ups (12 sets of push ups per week in total). Suddenly something happened in our life and now we have time for only 2 workouts. If we expect the same results as before we should increase the number of sets per workout to 6 so we still have 12 sets in total per week.
2.Reps in reserve (RIR). In general it's not the best idea to do each set to failure. Someone who does this, e.g. in each set does as much push ups as he/she can will not be able to (and probably shouldn't) as many sets as someone who keeps a rep or two (or more) in reserve ("tank").
3.Recovery. Someone who sleeps well and enough, who don't stress as much in general in life will be able to recover better from harder workout.
4.Energy availability. The more calories we eat, the more we can do.
5.Training experience. Someone who is just starting their adventure with resistance training doesn't regenerate as well as someone who has several years of experience.
6.Drugs usage. External "boosters" allow us to do more and harder workouts in general.
So what is the minimum number of sets we should do for muscle growth?
Let's start with the minimum number of sets that's necessary for muscle growth. We've got a few papers here, e.g. D. B. Starkey et al., 1996; Bent R. Rønnestad et al., 2007; M. Bottaro et al., 2010; Heiki Sooneste et al., 2013. They show us that even 1 set to failure per workout performed 2-3 times per week is enough to notice muscle growth in untrained people. Karl J. Ostrowski et al., 1997 shows us that 2-3 sets to failure per week is enough even for experienced people.
This is also confirmed by this meta-analysis (a research that analyzes more researches). Here's what we can read in summary: performing 1 set to or close to failure, 6-12 rep range, 2-3 times per week is enough to make significant progres in muscle mass growth and strength (1RM).
In this interesting study one group did 3 sets of knee extension and 1 set of bicep curls, the 2nd group vice versa. 8-12 rep range, 2 times per week. There was a significant growth of bicep brachii in both groups, but not in rectus femoris. It can be caused by the reason that we use the rectus femoris muscle much more in our daily life than bicep and it's already not that easy to grow that muscle. Or some muscle groups need more volume than the others? We don't know yet, but more likely it's beacuse the first reason.
It seems that for both unexperienced and experienced people 2-3 sets to failure per muscle group per week for significant muscle growth. But to be 100% sure I'd suggest to do twice as much if you're already experienced in resistance training.
If training is not a priority for someone and doesn't care about maximizing results, even such a short workotu will be MUCH better than doing nothing.We can use this fact e.g. if we are on holiday or if we don't have enough time to do a full workout.
What's the best number of sets which result in the best muscle growth and strength? Where's the upper limit above which we will not notice any greater gains? Or maybe more always = better?
F. Damas, 2019 shows us that doing 12 sets results in only slightly more MPS increase (the most important process in muscle building, like adding another bricks to the wall which are our muscles) than doing 8 sets per muscle group per workout to failure and that difference in MPS increase was probably caused by more muscle damage in 12 sets group (bricks had to be used for repairing the wall rather than building bigger wall).Conclusion: the upper limit of number of sets per workout per muscle group is somewhere between 8 and 12.
K. J. Ostrowski, 1997 were 3 groups: 1st was doing 7 sets for tricep, 2nd 14 sets, 3rd 28 sets divided into 2 training sessions per week. Growth of triceps for each group:Group 1, 7 sets: 2,3%Group 2, 14 sets: 4,7%Group 3, 28 sets, 4,8%
We can see that the difference between group 2 and 3 was very little, almost unnoticeable.Conclusion: the upper limit of number of sets per workout per muscle group is somewhere between 7 and 14 sets (similar to the above research)
B. J. Schoenfeld, 2016 meta-analysis summarized 15 studies comparing 1-4 vs. 5-9 vs. 10+ sets per muscle group per week. Muscle growth in 10+ sets was almost twice as large as in 1-4 sets. It is worth mentioning that the increase in 1-4 sets - although smaller - was still at a really good level. Generally speaking, 10-20 sets per week per muscle group is the best choice. If you do below 10 and the progres is a bit slow, then you should consider increasing the number of sets. On the other side, if you do more than 20 sets and you've reached plateau or the progres is slower and slower, you should consider decreasing the number of sets.
S. R. Heaselgrave, 2019, 3 groups: 9 sets, 18 sets and 27 sets for bicep per week. The greatest increase in muscle mass were in 18 sets group, even though the difference between all groups wasn't that big.
We should keep in mind a few things:
1.10-20 sets/week is an average value. There were single people in the study who responded better to a lower or higher number of series.
2.All sets were taken to or close to failure, 6-12 rep range.
3.Both too small and to many sets are not optimal for building muscle mass. It's worth remembering and start looking in that 10-20 set range per muscle group.
4.More is not always better! If the upper limit of sets is 20 it doesn't mean that we always should do 20 sets per week per each muscle group. Our body will quickly say "enough" and we'll not see any further progress. Muscles don't grow during our workouts, but afterwards. It's our body's response to the stimulus of workout that results in an increase in muscle mass. That's why must find a happy medium between a hard workouts and recovery.
5.The more advanced we are, the more sets we need. Closer and more frequently in 15-20 sets range per week than 10-15 (14 actually)
There's no one the best number of sets. It's very individual. This post is only a general guidline.
Minimum number of sets for muscle growth: 2-3 for beginners, 3-6 for advanced, per week per muscle group, to failure.
Optimum number of sets for muscle growth per workout: 5-10 per muscle group, to or close to failure
Optimum number of sets for muscle growth per week: 10-20 per muscle group, to or close to failure
No progress and you do 5-8 sets per muscle group per week to or close to failure? Increase number of sets
No progress and you do 20-25 sets per muscle group per week to or close to failure? Decrease number of sets
More does not always = better!
