How Many Sets per Muscle Group per Week

What the research says about weekly volume

Once sets are hard, weekly sets per muscle is the training variable with the most consistent dose-response link to muscle growth. The findings:

• More sets grow more muscle, up to a point. A 2017 meta-analysis by Schoenfeld, Ogborn and Krieger found a graded dose-response: groups doing 10 or more sets per muscle per week grew more than groups doing fewer than 5, with 5 to 9 in between.
• The returns shrink as sets go up. Going from 4 to 10 sets a week is a large step. Going from 16 to 22 is a small one, and costs a lot more recovery. A 2022 systematic review by Baz-Valle and colleagues put the useful band for trained lifters at roughly 12 to 20 sets per muscle per week.
• Indirect sets count, but not fully. A 2024 meta-regression of 67 studies by Pelland and colleagues found that counting a set as half for muscles that only assist predicted growth better than counting it as zero or as a full set. The same analysis found returns flatten faster for strength than for size.

Rep ranges and effort per set are covered in sets and reps by goal; anywhere from about 5 to 30 reps, growth per hard set is similar.

How to count sets: the five rules

1. Only hard sets count. A hard set ends at failure or with up to 3 reps left in the tank. If you could have done eight more, it was practice, not volume. The RPE and RIR chart shows how to estimate reps in reserve honestly.
2. Warm-up sets never count. The ramp from the empty bar to your working weight is preparation.
3. Prime movers get 1, helpers get 0.5. Rows and pulldowns: 1 for back, 0.5 for biceps. Bench press: 1 for chest, 0.5 for triceps and front delts. Overhead press: 1 for front delts, 0.5 for triceps and side delts. Squats and lunges: 1 for quads, 0.5 for glutes. Romanian deadlifts: 1 for hamstrings, 0.5 for glutes.
4. One-sided exercises count once. A set of split squats on the left leg and then the right is one set, not two.
5. Count the week, not the session. Four sets on Monday and four on Thursday is eight sets. Missed a session? Let the week be short rather than cramming the sets into the next day.

Small muscles get most of their work from big lifts. Front delts get plenty from pressing; most people need no direct front-delt work at all. Biceps and triceps get 4 to 6 sets' worth of half credit a week from a normal program before any curls or pushdowns.

A worked example: counting one real week

A four-day upper/lower split, all sets hard, 3 sets per exercise unless noted:

• Upper A: bench press, barbell row, overhead press, lat pulldown, lateral raise, curl (2 sets), triceps pushdown (2 sets)
• Lower A: squat, Romanian deadlift, leg press, lying leg curl, calf raise
• Upper B: incline dumbbell press, seated cable row, pull-up, lateral raise, curl (2 sets), overhead triceps extension (2 sets)
• Lower B: hip thrust, Bulgarian split squat, leg extension, seated leg curl, calf raise

The program looked balanced and was not: chest had half the volume of back, a common result the first time people count. The fix is 4 sets a week of one isolation exercise, about 6 minutes per upper day, not a new program.

Weekly volume by split

The split decides how many sessions share the weekly total. The table shows sets per muscle per session needed to hit 10, 14 or 18 sets a week. The workout split guide covers how to choose the split itself.

The practical limit is per session. Research has not pinned down an exact number, but most coaches cap one muscle at about 8 to 10 hard sets per session, because later sets are done tired, with less weight, and add little. Session length is the other limit: every set adds its working time plus the rest after it, and rest between sets shows how supersets fit more sets into the same hour without cutting rest on the main lifts. When a muscle needs more, spread it over another day. That is also why intermediates often move from 3 full-body days to 4 or 6 split days: 14 sets for every muscle no longer fits into three sessions of sane length.

Sets per muscle: a starting week for intermediates

Muscles are not equal. Big muscles that do most of the work in compound lifts need the most direct sets; small ones pick up a lot of half-credit volume. A starting point for someone one to three years in:

Women use the same numbers; the studies behind them include women. To bias glutes and legs, move sets rather than adding them everywhere: take 3 sets from upper-body isolation work and give them to hip thrusts.

If you are over 50, returning after a long break, or eating in a calorie deficit, start at the low end of each range and stay there for a full block before adding anything. If you have a heart condition, high blood pressure or a joint injury, check with your doctor before raising training volume.

When to add sets, and how many

Turn volume up slowly:

1. Exhaust progression first. As long as the weight or reps keep rising on the same sets, more sets add nothing but fatigue. Progressive overload is the first lever; volume is a later one.
2. Add only to a stalled muscle. No progress on its main exercise for 3 weeks, while sleep, food and attendance are steady.
3. Add 2 sets a week, not 6. One set to each of two sessions. Hold it for 3 to 4 weeks, and log weights and sets in the printable progressive overload tracker so you can see whether it worked.
4. Pull back after a hard block. After 4 to 8 weeks of rising volume, a deload week cuts sets by about half, and the next block starts a little below where the last one ended.

A worked example. Quads are at 10 sets a week (5 per lower day) and the squat has sat at 100 kg (225 lb) for 4 × 6 for three weeks. Add one set of leg press to each lower day: 12 sets. If the squat reaches 102.5 kg (230 lb) for 4 × 6 within four weeks, hold 12 sets until it stalls again; the next step is 14. If it has not moved after 4 weeks, more volume is not the answer, and the strength plateau guide walks through what to check next.

Signs you are doing too many sets

Too much volume does not feel like hard training. It feels like getting weaker for no reason. Watch performance first; soreness alone is a poor guide.

Signs of too little are quieter: sets feel easy, the weights stopped moving, and you recover with energy to spare. Then add sets, 2 at a time, to the muscles you care most about.

Questions people ask

How many sets per muscle group per week for hypertrophy?

About 10 to 20 hard sets for most lifters. Beginners grow well on 6 to 12. Start low and add sets only when progress stops.

Is 10 sets per muscle per week enough?

Yes, for most people in their first two years, as long as the weights keep going up.

Is 20 sets per week too much?

For one or two priority muscles, it is a fair upper target for experienced lifters. For every muscle at once, most people cannot recover from it.

How many sets per muscle per workout?

Usually 3 to 8 hard sets. Past about 10, spread them over another day.

How many sets to maintain muscle?

Far fewer than it took to build it. In a 2011 study by Bickel and colleagues, younger adults kept their muscle size for 32 weeks on one ninth of their original training: one session a week, one set per exercise. Adults over 60 needed a third of it and still lost some size. Keep the weights heavy and the sets hard.

Does weekly volume matter for strength?

Less than for size. For strength, heavy sets of the lift you want to improve matter more; 3 to 5 heavy sets of a main lift two or three times a week covers most people.

Where these numbers come from

The dose-response between weekly sets and muscle growth comes from Schoenfeld, Ogborn and Krieger, Dose-response relationship between weekly resistance training volume and increases in muscle mass (Journal of Sports Sciences, 2017). The 12 to 20 set band for trained lifters is from Baz-Valle and colleagues, A systematic review of the effects of different resistance training volumes on muscle hypertrophy (Journal of Human Kinetics, 2022). Half-credit counting for assisting muscles follows the dose-response meta-regressions by Pelland and colleagues on weekly volume and frequency.

Beginner starting volumes are in line with the ACSM position stand Progression Models in Resistance Training for Healthy Adults (2009), which recommends 1 to 3 sets per exercise, 2 to 3 days a week, for novices. Maintenance volume is from Bickel, Cross and Bamman, Exercise dosing to retain resistance training adaptations in young and older adults (Medicine & Science in Sports & Exercise, 2011).
