How many sets per muscle per week?

For most people building muscle, about 10 to 20 hard sets per muscle per week works well. Beginners grow on less. Here is what counts as a set, how to count compound lifts, and how to find your own number.

The short answer

You are	Hard sets per muscle per week
Starting out, or short on time	6–10
Training regularly for a year or more	10–20
Keeping what you have	About a third of your usual sets

These are ranges, not targets. Research on training volume finds that more sets bring more growth up to a point, with smaller gains each time you add more, and the point is different for every person and every muscle.

What counts as a hard set

A hard set ends close to failure: with about three reps or fewer left in the tank. Warm-up sets don’t count, and neither do sets you stop with ten easy reps to spare. Ten sets taken close to failure do far more than twenty easy ones.

Counting compound lifts

A bench press trains the chest most, but the triceps and the front of the shoulders work too. A simple way to count it: a full set for the muscle an exercise mainly trains, and half a set for each muscle that helps.

So 3 sets of bench press count as 3 sets for the chest, 1.5 for the triceps and 1.5 for the front delts. That is why many programs need fewer direct arm sets than you might think: rows and pulldowns already give the biceps a good share.

Spread them across the week

Twenty sets for one muscle in a single session is too much to do well: the last sets are done tired and add little. Split them across at least two sessions. A rough ceiling is around 6 to 10 hard sets per muscle in one session. This is the main reason splits that train each muscle twice a week are popular (see how to choose a split).

Finding your number

Start near the bottom of your range for a few weeks.
If your lifts keep going up, stay there. More sets are only worth it when progress slows.
If a muscle stalls and you recover well, add one or two sets a week for it and give it a few weeks.
If you feel worn out, sleep badly or your lifts go down, you are doing more than you can recover from. Cut back.

See your sets per muscle

Every program on this site lists its weekly sets per muscle, counted the same way. In Musclist, every workout ends with a muscle map: the darker a muscle, the more sets it got, so gaps in your week are easy to spot. The optional weekly coach report adds up your sets per muscle and suggests what to adjust.
