"How many sets should I do?" is the question that sits under almost every beginner programme. The honest answer is a range, not a number, and the range is smaller than the internet makes it look. This guide shows you how to count your own week, so you can see where you actually are.
A set is one run of reps without putting the weight down. For volume, only hard sets count: sets that end with about one to three reps still in the tank. Warm-up sets and sets where you stopped far from effort don't add much. If "reps in reserve" is new to you, our guide on judging effort covers it.
Volume is usually counted per muscle, per week. A week gives you a stable unit: it doesn't matter whether you train three full-body days or four split days, only how many hard sets each muscle gets in total.
A widely cited 2017 meta-analysis (Schoenfeld, Ogborn and Krieger) found that muscle growth rose with weekly volume: fewer than 5 sets per muscle gave the least, 5 to 9 gave more, and 10 or more gave more again. The 2026 American College of Sports Medicine resistance-training guidance likewise points to roughly 10 sets per muscle group per week for muscle growth, and says that training all major muscle groups at least twice a week matters more than chasing a perfect plan.
Two cautions. First, that research is mostly on people who already train; new lifters grow on much less, because almost anything is new to the body. Second, more is not endlessly better: returns shrink as sets pile up, and extra volume costs recovery time. For a beginner, a sensible path is to start low, around 4 to 6 hard sets per muscle per week, and build toward about 10 only if you are recovering well and want faster progress.
Pick how many hard sets of each exercise you do in a typical week. A bench press set mostly works the chest but also loads the triceps and shoulders, so helper muscles get half a set of credit. That is a simplification, but it matches how most coaches count.
The shaded band on each bar is 4 to 9 sets, the range where most beginners can grow well while still recovering between sessions. Try the "2 full-body days" preset: with only three or four exercises per session, most muscles land in or near that band. That is why simple programmes work for beginners.
If one muscle shows zero, it is not a problem by itself; the bars do not count every possible exercise. They simply show where your plan is thin. If a muscle is above 15, ask whether those sets are truly hard sets, and whether you are sleeping and eating enough to get value from them.
Add sets slowly, and only for a reason. A good rule: if you finish most sessions feeling fine, your weights or reps are creeping up, and your joints feel normal, add one or two sets to a muscle you want to grow, hold for a few weeks, and check again. If your lifts stall or you dread sessions, adding more is rarely the fix; sleep, food and effort quality usually matter more.
Drop back if soreness lingers for days, your performance falls week after week, or you feel run down. Sharp or persistent pain, or a health condition that makes exercise a question mark, is a reason to speak to a doctor or physio, not to adjust sets.
This is a starting guide for general muscle and strength gains. It is not tuned for sport-specific training, for people coming back from injury, or for anyone with a medical condition that affects exercise. In those cases, get advice from a professional who can see you.
