How many sets per muscle group per week?

The short answer

If you train to build muscle, a sensible weekly target for most muscle groups is somewhere between 10 and 20 hard sets. Where you land in that range depends mostly on how long you have been training, how well you recover, and how much a particular muscle matters to you right now.

A few rules of thumb cover most situations:

These ranges are practical starting points, not laws. The research behind them shows a clear trend (more sets lead to more growth, up to a point), but it does not hand everyone the same number. Start near the low end of your range, run it for a few weeks, and let your own results tell you whether to add more.

Two things matter as much as the number itself. The first is that only hard sets count: sets taken to within a few reps of failure. Ten easy sets are not ten sets of stimulus. The second is that the sets need to be spread sensibly: twenty sets of chest crammed into one Monday session is not the same week as ten on Monday and ten on Thursday. Both points get their own section below, because they decide whether a given weekly number actually works.

If you only remember one thing from this guide, make it this: pick a number in the range, log every set, and change the number based on what your log shows, not on what someone else does.

What counts as a set

Weekly volume is only useful if you count it the same way every week. Three rules keep the count honest.

Only hard sets count. A hard set ends close to failure, roughly three or fewer reps short of it, which is about RPE 7 or higher. If you rate effort with RPE, anything at 7 and above counts; a set at RPE 5, where you could have done five more reps, mostly does not. The RPE chart explains the scale if you are new to it.

Warm-ups don’t count. Ramping up to your working weight is useful preparation, but those sets are too easy to drive growth. Leave them out of the total, and make sure whatever you log in leaves them out too.

Count direct and indirect work differently. A barbell row trains your lats and upper back directly, and your biceps and rear delts along the way. Counting the row as a full set for every muscle it touches makes your arm volume look far higher than it really is. A common fix is to count a set as one set for the main muscle and half a set for each helper. A large review of the research by Pelland and colleagues used exactly that kind of fractional counting for indirect work.

Example: counting a push day. Say Monday is 4 sets of bench press, 3 sets of incline dumbbell press and 3 sets of triceps pushdowns, all taken close to failure. Chest gets the 7 pressing sets as direct work: 7. Triceps get the 3 pushdowns directly plus half of the 7 presses: 3 + 3.5 = 6.5. Front delts get half of the presses: 3.5. The same session looks like 10 sets of everything if you count it carelessly, and that is how arm and shoulder volume quietly ends up far higher than planned.

Drop sets and other intensity techniques are the one grey area. Each drop is a hard effort, but it is a short one, and most lifters count a drop set as one extra set rather than three. Pick a rule and stick to it; consistency matters more than which rule you choose.

What the research shows

The idea that more sets build more muscle, up to a point, comes from a fairly consistent body of research, with some important limits.

The most cited starting point is a 2017 meta-analysis by Brad Schoenfeld, Dan Ogborn and James Krieger, which pooled 34 groups of lifters from 15 studies. Treating weekly sets as a sliding scale, each additional set per muscle per week was associated with a small but real increase in muscle growth. Splitting the data into fewer than 5, 5 to 9, and 10 or more weekly sets per muscle pointed the same way, with the most growth in the 10-plus group, though that comparison fell just short of statistical significance. The authors also noted that they had too little data to say anything about volumes far above 10, and that very few of the studies used experienced lifters.

A 2019 study by Schoenfeld and colleagues looked at trained men specifically. Thirty-four of them did 1, 3 or 5 sets per exercise, three times a week for 8 weeks. Strength went up about the same in every group. Muscle size, measured in the arms and thighs, grew more in the higher-volume groups. That pattern, size responding to volume more than strength does, shows up repeatedly.

The largest analysis so far is a preprint by Pelland and colleagues, which pulled together 67 studies and over 2,000 participants. It found that both muscle growth and strength rise with weekly volume, but with diminishing returns: the first few weekly sets do the most, and each extra set adds a little less. Strength gains flattened at much lower volumes than muscle size did. Training frequency mattered more for strength than for size. Because it is a preprint, treat its exact numbers as provisional.

There is a fair counter-argument to all of this. Most studies run for 8 to 12 weeks, many use young men or beginners, and the dose-response curve describes averages, not individuals. Some people grow well on modest volume; others need more. That is exactly why the practical advice in this guide is to treat the research as a starting range and your own log as the final word.

How many sets for your level

Experience changes the answer more than anything else, because the same weekly volume is a big stimulus for a beginner and a maintenance dose for someone with years of training behind them.

In your first year. Six to ten hard sets per muscle per week is plenty. A beginner full-body program with three or four main lifts, done three times a week, lands in that range without trying. The bigger risks at this stage are inconsistency and poor technique, not too little volume. Adding sets does little when you can still add weight to the bar almost every week.

After the first year or two. Progress slows, and volume becomes a real lever. Ten to fifteen hard sets per muscle per week is where most intermediate programs sit, usually spread over two sessions per muscle. This is also the stage where tracking matters most, because the difference between 10 and 15 sets is easy to lose track of across a busy week.

After three or more years. Twelve to twenty sets per muscle is common, and some lifters push a priority muscle past twenty for a block. At this level it pays to specialize: raise the volume for the two or three muscles you most want to grow, and drop the rest to maintenance, around four to six hard sets a week, so the total workload stays recoverable.

When you mainly train for strength. Strength responds to volume too, but it flattens out sooner, and heavy sets are more fatiguing per set. Four to ten hard sets per main lift per week, with most of them in lower rep ranges, covers most strength programs. Muscle you build along the way helps, so many strength lifters add a little higher-rep accessory work on top.

When life gets in the way. Poor sleep, a calorie deficit, a stressful month at work or a lot of other sport all eat into recovery. Dropping to the low end of your range for a few weeks is a better plan than grinding through a volume you can’t recover from.

Sets for each muscle group

Not every muscle needs the same number of direct sets, because compound lifts already train several of them. The table below gives practical starting ranges for an intermediate lifter, counting hard sets of exercises aimed at that muscle, and notes where compound lifts already cover a lot of the work.

Three patterns stand out. Front delts and glutes often need little or no direct work, because pressing and squatting already train them hard. Side delts and calves are the opposite: almost nothing else trains them, so if you want them to grow, nearly all their volume has to be direct. Arms sit in between: rows and presses give them meaningful indirect work, which is why counting indirect sets as halves matters most for biceps and triceps.

If a muscle is not growing and you are sure you are counting its sets correctly, the fix is usually more direct work for that muscle, not more volume everywhere.

Spreading sets across the week

Once you have a weekly number, how you split it matters. The total drives growth, but the distribution decides whether each set is a good one.

Train each muscle about twice a week. For muscle size, the evidence suggests frequency matters less than total volume, but two sessions per muscle is the practical default for a simple reason: it keeps each session to a manageable number of sets. Fourteen weekly chest sets become seven on Monday and seven on Thursday, rather than fourteen in a row. A six-day push pull legs routine builds this in.

Keep each session to roughly 6 to 10 hard sets per muscle. Past that point, most lifters find the later sets get sloppier, lighter, or both. If a muscle needs more than about 20 sets a week, a third session for it usually works better than longer workouts.

Here is a four-day upper/lower week for an intermediate lifter:

The arm totals count each row, pull-up, pull-down and press as half a set, as in the counting section above. That week lands chest at 11, back at 14, quads at 11, hamstrings at 9, side delts at 8 and calves at 8, all inside the intermediate ranges in the muscle table, and no muscle gets more than 7 hard sets in one session. If chest growth is the priority, adding a set of bench on Monday and a set of incline on Thursday takes it to 13 without making either session much longer.

Order matters too. Put the muscles you are prioritizing first in the session, when you are freshest, and push the maintenance work to the end.

When to add or cut sets

The right weekly volume is the one you can recover from that still drives progress. Your log answers that better than any table, if you look at it the right way.

Step 1: hold your volume for three to four weeks. Changing sets every week makes it impossible to tell what worked. Pick a number in your range for each muscle and keep it steady for a block.

Step 2: check progress on the main exercise for each muscle. What done looks like: over those weeks, the weight or the reps at a given weight went up on most of your main lifts, and an RPE 8 set still feels like an RPE 8 rather than creeping toward 9 or 10. If that is happening, keep the volume and keep going. More sets would only add fatigue.

Step 3: if a muscle has stalled but you recover well, add two sets. Recovering well means no soreness lingering into the next session for that muscle, sleep and energy are fine, and your other lifts are still moving. Add two hard sets per week for the stalled muscle, not for everything, and run another three or four weeks.

Step 4: if you’re behind, meaning performance is dropping, cut instead. If several lifts are going backwards, sets that used to be RPE 8 are landing at 9 or 9.5, or joints ache going into sessions, the volume is outrunning your recovery. Take a deload week, then restart about 20 to 30% below where you were. The deload guide covers how to run the easy week and how to come back from it.

Step 5: repeat. Most lifters find their productive range settles within a few blocks, and it tends to creep up slowly over years of training.

One caution: change one thing at a time. Adding sets in the same block as switching exercises, starting a diet or doubling your cardio makes it impossible to tell which change caused the result.

Mistakes when counting volume

Most volume problems come from counting, not from choosing the wrong number.

Counting warm-ups and easy sets. If half your logged sets are warm-ups or sets stopped far from failure, your “15 sets” is really seven or eight. That is the most common reason a program seems to have plenty of volume and still produces little.

Forgetting indirect work. Three sets of curls looks like a small amount of biceps work until you add the halves from six sets of rows and pull-downs, which brings it to six. Counting only direct sets leads lifters to add arm volume they don’t need, and then wonder why their elbows ache.

Copying advanced lifters. A competitive bodybuilder running 25 sets for a lagging muscle has years of training and recovery behind that number. Starting there as an intermediate lifter usually means a lot of sets, a lot of soreness and little extra growth.

Giving every muscle the same number. As the muscle table shows, front delts and side delts need very different amounts of direct work. Twelve sets for everything over-trains some muscles and under-trains others.

Adding volume and effort at the same time. Pushing more sets closer to failure in the same week stacks two kinds of fatigue at once. Raise one, see how you recover, then consider the other.

Junk sets at the end of a session. Sets done after your performance has clearly dropped, with lighter weights and too little rest between sets just to hit a number, add fatigue without much growth. If the last sets of a session are always bad, spread the work over another day instead.

What not to rely on

Some signals feel like they measure volume but mislead more than they help.

Soreness. Muscle soreness mostly tracks how new or unusual the work is, not how much it made you grow. A muscle you train often stops getting sore while still growing, and a new exercise can leave you sore for days after a modest amount of work. Use soreness as a recovery check, not as proof the volume was right.

The pump. A good pump is pleasant and may play a small part in growth, but it is a poor guide to whether your weekly volume is right. Easy, high-rep sets can give a big pump while being far from failure.

Tonnage as your only volume measure. Weight × reps × sets is useful for tracking one exercise over time, but it misleads across exercises: a leg press session racks up several times the tonnage of a dumbbell curl session without being several times the stimulus. For planning, hard sets per muscle are the better unit.

A plain notes app or paper log. Both record what you did, but neither adds up your sets per muscle across a week or separates direct from indirect work, so the weekly picture stays in your head, where it is easy to get wrong.

Fitness trackers that count steps and calories. They say a lot about daily activity and very little about lifting volume. A heavy leg day and a long walk can look similar on a calorie estimate.

What actually helps is a log that keeps every set with its weight, reps and effort, and that adds up sets per muscle for you.

Tracking weekly sets in Arclift

Arclift is the app I build, so read this section knowing I have a stake in it. It is also the part of this guide that the app does for you.

Logging is free. Every set you log, with its weight, reps and RPE, goes into your history, with last time’s numbers shown beside the field you are filling in. Warm-up sets are marked as warm-ups when you log them, so they never inflate your counts. You can log a set with one thumb on Arclift’s keypad and save each training day as a reusable workout template, so the week you planned is the week you do.

The body map counts your weekly sets per muscle (Pro). Arclift’s recovery and load map shows the last seven days of work for every muscle group, counted as weighted sets: each completed, non-warmup set counts fully toward the muscles an exercise mainly trains, and partly toward the ones it only helps, the same idea as the half-set rule above. It ranks the muscle groups you have been neglecting, and shows how recovered each one is right now, so you can see at a glance whether this week’s volume matches your plan. The bodybuilding page shows how it fits a hypertrophy split.

The progression coach turns the sets into next week’s numbers (Pro). Once your volume is set, the coach handles the other half of the job: it sets the weight and reps for each exercise’s next session, flags stalls and calls deloads. The progressive overload page covers how it decides.

Other apps do parts of this too, some for free. Hevy charts sets per muscle group by week in its free plan, for up to three months back, which Arclift only does with Pro. The comparison of Arclift and Hevy covers where each app is stronger. The one-rep max calculator is there if you want to turn a hard set into an estimated max as you go.

What the research can’t tell you yet

The volume research is better than most areas of training science, but it still leaves real gaps, and it helps to know where they are.

Individual differences are large. Every study reports averages. Within the same study and the same program, some participants grow a lot and some barely at all, and we can’t yet predict in advance who needs more volume and who needs less. That is the main reason to treat any range, including the ones in this guide, as a starting point.

Most studies are short. Eight to twelve weeks is typical. Whether the volumes that work best over two months also work best over two years, as fatigue, motivation and life accumulate, is mostly unknown.

Most participants are young. Older lifters, women and people training around jobs and families are under-represented, so the averages may not fit them as well.

Counting rules vary between studies. How to count indirect work, what counts as close enough to failure and how drop sets are treated all differ, which makes the exact numbers less certain than they look. The newest analyses address this by counting indirect sets as fractions, which is a step forward, but those findings are partly still preprints.

So the honest summary is this: more hard sets build more muscle, with diminishing returns, and the useful range for most people sits somewhere around 10 to 20 per muscle per week. Where you fall within it is something only your own training log can show, which is why logging every set, and looking at the numbers every few weeks, matters more than picking the perfect number on day one.
