How many sets per muscle per week? An honest answer from the evidence

TL;DR: For most trained lifters, the working range is 10–20 hard sets per muscle per week. Newer lifters grow on 6–10. Past 20 you hit diminishing returns unless you've earned the recovery capacity through years of training. The honest answer isn't a number. It's a window, and your job is to find where in that window you live right now.

If you've spent any time on lifting forums, you've seen the fight. A 5×5 purist will tell you 5 sets of squats a week builds world-class legs. A bodybuilder coming off a Jeff Nippard video will tell you to hit quads with 25 sets across three sessions. Both will cite research. Both will have before-and-after photos. Both will be partially right, because the truthful answer to "how many sets per muscle per week?" is not a single number. It's a range bounded by your training age, your recovery, and the specific muscle in question.

What follows is what the evidence actually says, translated into numbers you can program against tomorrow.

The Schoenfeld dose-response review

The single most-cited paper on this question is Brad Schoenfeld, Dan Ogborn, and James Krieger's 2017 meta-analysis, "Dose-response relationship between weekly resistance training volume and increases in muscle mass." It's the paper every coach who claims a number has either read or pretended to read.

Schoenfeld and colleagues pooled 15 studies that varied weekly set volume and measured hypertrophy. The headline finding: more sets produced more muscle, in a graded, dose-dependent way. Specifically, studies that used more than 10 sets per muscle per week produced significantly greater hypertrophy than those using fewer than 10. The effect size favoring higher volume was roughly 0.24, a meaningful but not overwhelming advantage.

That's the result people quote. It's also the result people oversimplify. A few things the paper does not say:

It does not say more is always better without limit. The studies included mostly fell in the 5-to-10-plus range. Almost none went past 20 sets per muscle per week, so the meta-analysis can't speak to what happens above that. It shows a rising line where we have data; it does not extrapolate that line to infinity.

It does not say 10 is the magic number. The threshold was the cleanest place to cut the data, not a biological constant. A lifter doing 9 sets is not meaningfully worse off than one doing 11. Ranges, not thresholds.

It does not equalize proximity to failure. Some studies took sets to failure; others left reps in reserve. Volume without intensity context is noise, which is why the same paper's authors have since argued that effective volume (sets taken close enough to failure to recruit high-threshold motor units) is what actually drives growth.

Schoenfeld's later work, and Krieger's follow-up analyses, refined the picture. The dose-response relationship is curvilinear: each additional set adds a little less hypertrophy than the last, and at some point the curve flattens. A 2019 paper from Schoenfeld's group specifically tested high volumes (up to 45 sets per week for a muscle in resistance-trained men) and found that beyond roughly 20 sets per week, returns were not reliably better, and in some subjects, worse.

The practical synthesis most coaches have converged on: 10 sets per muscle per week is a strong baseline for trained lifters, 15 is often better if you recover well, and 20 is an upper bound you should approach only if you've systematically earned the capacity for it. That's the shape of the Schoenfeld curve if you read it honestly.

The Israetel MV/MEV/MAV/MRV landmarks

Dr. Mike Israetel and the Renaissance Periodization crew took the research and built a more usable framework around it. Instead of one number, they defined four landmarks for every muscle group. Once you see training through these, the "how many sets?" question stops feeling ambiguous.

MV, Maintenance Volume. The minimum number of weekly sets required to hold the muscle you already have. If you drop below MV, you will measurably lose size over weeks. For most muscles in a trained lifter, MV sits around 4–8 sets per week. Useful during deloads, illness, travel weeks, or when you're prioritizing a different muscle and just want to hold ground on this one.

MEV, Minimum Effective Volume. The minimum weekly sets that actually produce new growth. Below MEV, you maintain. At MEV, the needle moves. This is the floor of a serious hypertrophy block. For most muscles in a trained lifter, MEV is roughly 8–10 sets per week. For small muscles like biceps, triceps, side delts, and calves it can sit a few sets lower (and yes, biceps and triceps do need direct work to reach MEV in most programs).

MAV, Maximum Adaptive Volume. The sweet spot. The volume at which you grow fastest without digging a recovery hole you can't climb out of. MAV is the range programs should spend most of their time in. For trained lifters, MAV typically lives between 10 and 20 sets per week, depending on the muscle and the person. This is the band where Schoenfeld's dose-response curve is still rising and recovery can still keep pace.

MRV, Maximum Recoverable Volume. The ceiling. Past MRV, you're adding stimulus your body can't process into growth. Performance drops from session to session, joints complain, sleep suffers, mood falls. For most muscles MRV sits around 20–26 sets per week, though it varies sharply by muscle. Quads and back tend to tolerate more; pecs, biceps, and side delts tend to tolerate less.

Practical per-muscle numbers the RP team publishes, in rough round ranges for an intermediate-to-advanced lifter:

• Chest: MEV 8, MAV 12–20, MRV ~22
• Back: MEV 10, MAV 14–22, MRV ~25
• Quads: MEV 8, MAV 12–18, MRV ~20
• Hamstrings: MEV 6, MAV 10–16, MRV ~20
• Shoulders (side delts): MEV 8, MAV 16–22, MRV ~26
• Biceps: MEV 8, MAV 14–20, MRV ~22
• Triceps: MEV 6, MAV 10–14, MRV ~18

Don't treat these as decimal-precise. Treat them as a window for programming that gets you out of the "just do more" trap. The RP model's real innovation isn't the numbers. It's the idea that volume should be periodized within a block: start near MEV, progressively add sets week to week as you adapt, approach MRV only at the end, then deload and restart. That's a structure, not a prescription.

If your lifting has plateaued on a fixed "3×10 everything" template, the Israetel landmarks are the single most useful mental upgrade you can make. Read our thesis for how we build that progression into Grov's programming rather than leaving it to guesswork.

Direct vs indirect sets

Here's a question that trips up set-counting: a barbell row is a back exercise, but your biceps are working the entire time. Does that set count toward your biceps volume?

Yes, partially. Electromyography studies and practical coaching experience both support a simple convention: direct work counts as 1.0 sets, indirect work counts as roughly 0.5 sets for the assisting muscle.

Concretely:

• A heavy barbell row: 1 set for back, ~0.5 set for biceps.
• A chin-up: 1 set for back, ~0.5 set for biceps (often closer to full for biceps if the grip is supinated and the rep range is moderate).
• A close-grip bench press: 1 set for chest, ~0.5 set for triceps.
• An overhead press: 1 set for shoulders, ~0.5 set for triceps.
• A Romanian deadlift: 1 set for hamstrings, ~0.5 set for glutes and lower back.

Why this matters: if you're rowing and chinning twice a week and then bolting on 12 sets of curls, your biceps are probably well past MAV and possibly at MRV. The extra curls might not be helping. They might be the reason your elbows are cranky.

The rule of thumb: count direct work first toward MEV/MAV, then treat indirect work as a buffer that usually gets you most of the way. For compound-heavy programs, a few sets of direct arm and calf work is typically enough. For isolation-heavy programs, direct volume is almost all the volume there is. Both can work; what doesn't work is double-counting everything at full weight and convincing yourself you're doing 30 sets of biceps per week.

Why volume alone isn't enough

Two lifters both do 12 sets of bench press per week. Lifter A stops every set with 4 reps in reserve. Lifter B pushes every set to technical failure. Same volume on paper. Very different training effect. The research community has increasingly converged on a term for this: effective volume, sets taken close enough to failure (typically within 0–3 reps of it) to recruit the high-threshold motor units that drive hypertrophy.

Schoenfeld, Helms, and others have argued for years that sets left far from failure don't count equally toward the weekly tally. A set at RPE 6 produces much less muscle-building stimulus than a set at RPE 9. If half your sets are warm-ups in disguise, you might be nominally hitting 15 sets a week while effectively training at 7.

This is where autoregulation by RPE stops being a nice-to-have and becomes the mechanism that makes volume numbers meaningful. If you don't know how close to failure your sets are, you don't actually know your effective volume. You just know how many times you touched the bar.

Two practical implications:

1. When you count sets, count sets taken within ~3 reps of failure. Everything else is warm-up and technique work. It has value, but not as hypertrophy volume.
2. MEV and MAV numbers assume hard sets. If you're hitting 15 sets but only 8 of them are hard, your effective volume is 8, and you might be undershooting MEV without realizing it.

This is why we obsess over RPE at Grov rather than just set counts. Read our guide to RPE autoregulation for the practical side of dialing in effort.

How antagonist pairs let you hit volume in less time

Here's the operational problem with the volume numbers above: 15 sets for chest plus 15 for back plus 15 for quads plus 15 for hamstrings plus arms, shoulders, and calves gets to a lot of sets. If you rest three minutes between every set (as most hypertrophy research uses), you're looking at a two-hour session four days a week. That's unworkable for most lives.

Antagonist supersets solve the math. Pair a push with a pull (dumbbell press with a row, overhead press with a chin-up, leg extension with a leg curl) and rest ~90 seconds between the two exercises rather than three minutes between every set. The chest rests while the back works, and vice versa. Research on contralateral and antagonist pairing (Robbins, Robinson, and others) shows that performance on the second movement is largely preserved, and total session time drops 30–40%.

This isn't a gimmick. It's the only way most intermediate lifters can realistically accumulate 15+ sets per muscle per week without living at the gym. The trick isn't finding extra hours; it's not wasting the hours you have on rest periods that aren't doing anything.

We structure Grov's programming around antagonist pairs specifically because the volume math doesn't work any other way for people with jobs. Read more on how we build antagonist pairs for the exercise-selection side of this.

So, how many sets should you do?

Rules of thumb you can program against this week:

• New lifter (first 1–2 years): 6–10 hard sets per muscle per week. You grow on almost anything; don't overcomplicate it.
• Intermediate (2–5 years): 10–16 hard sets per muscle per week for most muscles, with progression across a training block.
• Advanced (5+ years, recovering well): 14–22 hard sets per muscle per week, periodized from MEV toward MRV across a block and then deloaded.
• Small muscles (side delts, biceps, triceps, calves): Often tolerate and need slightly higher volume than compound-trained muscles because they get less indirect work.
• Lagging muscles: Push them toward MAV while keeping maintaining-volume on everything else.
• When in doubt: Start low, add sets every 1–2 weeks, and watch your performance. If bar speed, load, or rep counts are improving, you're below MRV. When they stall, you've found your current ceiling. Deload and restart at MEV.

The honest answer to "how many sets per muscle per week?" is: somewhere between 8 and 22, depending on who you are today, which specific muscle, and how close to failure each set is. That's not a cop-out. It's the shape of the actual evidence. Anyone telling you a single number is either selling a program or hasn't read the literature.
