Chest, back, quads, calves — each one has a commonly cited weekly set range. The one that's actually yours only shows up after you test it.
The ranges below come from the same dose-response research and coaching heuristics behind volume landmarks. That page is the framework and its limits. This one is the practical numbers, by muscle.
These are the commonly cited starting ranges, in working sets per muscle group per week, for a lifter training with hypertrophy as a goal:
Those come from the volume landmark guidance popularized by Renaissance Periodization and Mike Israetel — the same coaching heuristic behind MEV, MAV and MRV — not from a single measurement of you. They vary somewhat by source for exactly that reason. Treat the low end as a safe place to start and the high end as a place most lifters never need to visit.
Counting every muscle a lift touches as a full working set is the fastest way to make these ranges meaningless. A bench press is direct volume for chest. It's assistance for triceps and front delts — real, but not the same dose, since those muscles aren't the ones being taken to their own limit. Count a set as direct volume for a muscle group only when that muscle is the prime mover.
The other variable that quietly changes what a set count means: how close to failure it's taken. Ten sets at 4 RIR and ten sets at 0 RIR are not the same stimulus, even though both are "ten sets." A 2023 systematic review from Refalo and colleagues and a 2024 series of meta-regressions from Robinson and colleagues both treat proximity to failure as its own studied variable, separate from the raw number. If your effort target drifts mid-block, your week-to-week counts stop being comparable to each other.
A 2017 meta-regression from Schoenfeld, Ogborn and Krieger, across 34 treatment groups, established that weekly resistance training volume has a real dose-response relationship with muscle growth. That's the finding underneath every landmark table you'll see published, including the one above.
What that paper doesn't do is hand you a per-muscle figure. It says more volume tends to produce more growth, up to a point. It doesn't say your chest's point is 18 and your hamstrings' is 12. That's why published ranges disagree with each other by a few sets in either direction — they're coaching heuristics layered on top of a real relationship, not a table of measured optima.
The usable process, the same one behind the ranges above: start a block near the bottom for the muscle you're prioritizing, add a set or two most weeks, and keep going until performance stalls or recovery visibly degrades. Wherever that happens is your number for this block — not the chart's number, yours.
Fire Your Coach counts your weekly sets per muscle group from what you actually logged, not from what the plan said, and shows this week's count next to the plan's. When a block ends, its recap keeps the weekly average for each muscle group, and the next block is written with those numbers in hand.
Once you're comparing weeks, the harder question is what a rising or flat set count actually means — that's how to track volume across blocks. And if the count keeps climbing while your numbers stall, that's usually the signal for when to deload, not for adding another set.
It depends on the muscle, but the commonly cited starting ranges are roughly 10 to 20 sets for chest, 10 to 25 for back, 12 to 26 combined for side and rear delts, 8 to 18 for quads, 6 to 16 for hamstrings, 4 to 12 direct sets for glutes, 8 to 20 for biceps, 6 to 18 for triceps, and 8 to 16 for calves. These are heuristic ranges from Renaissance Periodization-style volume landmark guidance, not a measurement of you specifically. Start near the bottom of the range for the muscle you care about and let a few weeks of your own progress move the number.
Only for the muscles doing the primary work. A bench press counts fully toward chest and partially toward triceps and front delts, since those muscles assist but are not the prime mover. Counting every assisted muscle as a full set inflates every total on the list and makes the ranges meaningless. The practical rule: count a set as direct volume for a muscle group only when that muscle is the one being taken close to its own limit.
No. Weekly volume has a real dose-response relationship with growth up to a point, but past that point added sets mostly add fatigue without added stimulus, which is what the upper end of each range represents. A set count rising while your top-set numbers stall or drop is the same pattern that means it's time to bring a deload forward, not add more work.
Start a block near the bottom of the published range for the muscle you're prioritizing. Add a set or two each week. Keep going until your numbers stop improving or recovery visibly degrades - that's your practical ceiling for this block, not a number off a chart. The next block starts a little higher, because now you know where the roof actually is.
Not exactly. Smaller, more resilient muscle groups tend to recover faster and often respond better to higher frequency spread across more sessions rather than a few large ones, which is why calves and rear delts commonly land toward the higher end of their relative range. The landmark framework still applies; the practical difference is how you spread the sets across the week.
