How many sets per week per muscle group?
The short answer
Most lifters do well somewhere between ten and twenty hard sets per muscle per week. Below about ten, you are usually leaving growth on the table. Above twenty, the extra sets tend to buy less and less while costing recovery you need elsewhere, so more volume stops being the answer and starts being the problem. Only sets taken close to failure count toward that total.
Two of Nirfit’s coaches take this one in opposite directions. Both are AI, and each one is built on a different real training methodology. Read the cases and pick the one you buy. If you want the bigger picture first, here’s why fitness advice conflicts in the first place.
The Bodybuilding coach
More sets, as long as you can recover from them.
Volume is the lever with the most room in it. You can only get so strong so fast, and you can only push intensity so far, but you can almost always do another couple of hard sets. That's where the growth in a stalled muscle comes from.
The people who preach low volume are usually already big. They built it on volume and now they maintain on less, then tell you the maintenance dose is the recipe.
Push it up gradually and watch what happens. If your performance holds and you're recovering between sessions, the volume isn't too high yet. Your body will tell you where the ceiling is long before a spreadsheet does.
The Science coach
Fewer sets, taken properly. Most junk volume is a quality problem.
Half the sets people count were never hard enough to count. Stopping four reps short does very little, and doing twenty of those is not high volume training, it is a long workout.
Once effort is genuinely high, the returns flatten fast. Adding sets past that point mostly buys fatigue, and fatigue is what stops you training hard on the next session, which is where the real cost shows up.
So audit the effort before you add anything. Ten sets you could not have done an eleventh rep on will beat twenty comfortable ones, every time.
Where they agree
Both coaches count the same way: only sets taken close to failure go on the tally. Neither has any interest in a set you finished feeling fine. The argument is about how many of those hard sets are worth doing, not about whether easy ones count.
How to settle it for yourself
- Count your current hard sets per muscle per week honestly. Most people find the real number is lower than they assumed.
- If you are under ten and not growing, add sets before you change anything else.
- If you are over twenty and stalled, cut back rather than adding. Stalling at high volume is rarely fixed with more of it.
- Add volume in small steps and hold it for a few weeks. Jumping straight to the top of the range tells you nothing about what you needed.
Common questions
- What counts as a set for weekly volume?
- A working set taken close to failure, roughly one to three reps short. Warm-up sets and sets stopped well short of that contribute very little and should not go on the tally.
- Is 20 sets per week too much?
- It is at the upper end of what most lifters recover from, and it is not automatically better than fifteen. If performance is dropping week to week at that volume, it is too much for you right now.
- Do compound lifts count toward multiple muscles?
- Partly. A row trains your back and your biceps, so it counts fully for the back and partially for the arms. Most coaches count direct work fully and indirect work as roughly half.
