How Many Sets Per Muscle Group Per Week: A Practical Guide

"How many sets should I do for chest?" is the wrong question until you add "per week"

When I started lifting, I counted sets per session. Monday was chest day, I did 16 sets of chest, and I walked out convinced I had crushed it. The rest of the week, chest sat idle. The result was that I hammered one muscle past the point of usefulness on a single day, then gave it zero stimulus for the next six.

Everything changed when I started counting volume per week instead of per session. A muscle does not know whether you did those 16 sets on Monday or split them into 8 on Monday and 8 on Thursday. All it knows is how much stimulus it received over the week, and whether it had time to recover.

This article answers the question almost every lifter eventually asks: how many sets per muscle group per week should you do to actually grow. We will walk through concrete ranges, beginners vs advanced lifters, how to count working sets, and how to spread them across sessions. No theory for theory's sake - just the things that translate into decisions at the bar.

The sweet spot: 10-20 working sets per week per muscle group

If you want one number to remember, here it is: for most muscle groups, aim for 10-20 working sets per week. This is not a rigid rule, it is the range that captures the vast majority of people training for hypertrophy.

Why a range and not a single number? Because the volume that is optimal for you depends on training age, recovery, sleep, nutrition, and how hard you push each set. Two people of the same height and weight can need different volumes to keep progressing. You can split the 10-20 range into three zones:

• Lower end (around 10 sets) - the minimum that reliably produces growth. A good starting point if you are returning from a break or just building volume up.
• Middle (12-16 sets) - where most consistent lifters land. A safe, productive zone for hypertrophy.
• Upper end (18-20 sets) - for advanced lifters who recover well and need more stimulus to keep moving.

Smaller muscles like biceps and calves often respond well to slightly lower direct numbers, because they pick up plenty of indirect volume from compound lifts. More on that shortly, when we get to counting working sets.

MEV and MAV without the jargon - two thresholds worth knowing

Online you will run into the abbreviations MEV and MAV. They sound intimidating, but they are just two points on the same volume axis. Understanding them gives you a framework for making decisions.

MEV - minimum effective volume. This is the smallest number of weekly sets at which a muscle actually grows. Below this threshold you maintain the muscle but do not build it. For many muscle groups MEV sits somewhere around 8-10 sets per week. That is good news: you do not need huge volumes to start seeing results.

MAV - maximum adaptive volume. This is the range where you get the most growth per unit of work. Above it, you go home tired, but the extra sets stop delivering proportional growth - and at some point they start eating into your recovery.

The practical takeaway is simple. Start near MEV, the lower end of the range, and add sets gradually over time when recovery allows. Do not open at 20 sets per week - because if that does not work, you have nowhere left to go. For more on the logic of adding volume over time, see the training volume guide.

Beginner vs advanced - why less is often more

This is where many people go wrong. They look at an advanced bodybuilder's plan with 20 sets per muscle and copy it from day one. That is the wrong order.

Beginners grow on surprisingly low volume. Your body responds to almost any reasonable stimulus, because everything is new to it. 10-12 sets per week per group is plenty to keep progressing for many months, and lower volume leaves you room to grow: if you start at the ceiling, you have nothing left to push the stimulus higher when progress slows.

Intermediate lifters usually need 12-18 sets per week, because adaptations come slower and it takes more work to force growth. Advanced lifters may require 16-20+ sets for some muscle groups, but only when recovery, sleep, and nutrition are all keeping up.

The single most important principle: only increase volume when your current volume stops producing results. Volume is a resource you spend, not a level you start at. The higher you begin, the faster you run out of options. That is why patience at lower numbers is an investment, not a sacrifice.

How to count working sets - and what not to count

Before you spread volume around, you need to know what you are actually counting. Here are a few rules that clean up the math.

Count working sets, not warm-ups. A light set of 15 loose reps is a warm-up, not a growth stimulus. What counts are sets taken close to failure - roughly 0-3 reps in reserve (RIR). If you finish a set with five reps left in the tank, it does very little for hypertrophy.

Compound lifts count toward multiple muscles - but use judgment. Bench press is primarily chest, but triceps and front delts get a solid stimulus too. As a rough rule, count such a lift as a full set for the primary muscle and half a set for the assisting muscle. This is why biceps and triceps need fewer direct sets - they pick up plenty of volume during rows and presses.

Example. In a week you do 4 sets of bench press, 4 sets of flyes, and 4 sets of incline press. That is 12 direct sets for chest. Your triceps pick up maybe 6 indirect sets from those movements, so you only add 6-8 direct triceps sets to land in range, instead of grinding out 16.

Doing this math in your head during a workout gets tedious fast. That is where a tool that does it for you comes in - I will come back to that at the end.

How to split sets across sessions - frequency matters

Say you have settled on 16 weekly sets for back. The question is: all in one day, or split across two?

Research and practice largely agree: spreading the same volume across 2-3 sessions usually works better than cramming it all into one day. Two reasons.

First, set quality. The sixteenth back set in a single session is far weaker than the first - you are fatigued, form slips, RIR creeps up against your will. Two sessions of 8 sets give you 16 fresher sets.

Second, more frequent stimulus. Muscle protein synthesis after training stays elevated for roughly a day or two. Training a muscle twice a week keeps it "switched on" for more of the week than one heavy day does.

A practical rule: at 10-12 sets per week, one or two sessions are enough; at 14-20 sets, split across 2-3 sessions. This naturally leads to upper/lower or push-pull-legs structures that hit each muscle twice a week. For how to match a split to your number of training days, see the workout split guide.

A sample weekly layout

So this does not stay theoretical, here is what weekly volume might look like for an intermediate lifter training four days a week on an upper/lower split:

Muscle group	Weekly sets	Distribution
Chest	14	7 + 7 across two upper sessions
Back	16	8 + 8 across two upper sessions
Legs (quads)	14	7 + 7 across two lower sessions
Shoulders (side delts)	12	6 + 6, plus indirect from presses
Biceps	8	4 + 4, plus indirect from rows
Triceps	8	4 + 4, plus indirect from presses

Notice that the smaller muscles have lower direct set counts, because they get a solid dose of indirect volume from compound movements. This is not less work - it is more accurately counted work. Every group lands in the 8-16 range and gets hit twice a week.

How Pully helps you track this

This whole conversation about volume comes down to one thing: you need to know how many sets you actually do, not how many you think you do. Memory lies, and "I feel like I do a lot of back" is not data.

In Pully you log every set in two taps, with auto-fill pulling your last session's weights. That gives you a real record instead of estimates.

A view of weekly volume shows how much total work you put in during a given week. This is a good first signal of whether you are doing a lot, a little, or about right overall, and how that changes week to week.

Pully can also show you the breakdown into specific muscle groups - exactly how many weekly sets landed on chest, back, or shoulders. This is what shows whether each individual group sits in the 10-20 range, or whether one muscle gets 6 sets while another gets 22. Without it, it is easy to unknowingly neglect one group while overdoing another.

To be clear: one view tells you how much you train overall, the other tells you exactly where that work lands per muscle. Both run off the same logs - it is a matter of how deeply you want to break them down. See the features page to view how it looks.

Summary - the numbers worth remembering

How many sets per muscle group per week? Here is everything from this article in five points:

1. Aim for 10-20 working sets per week per muscle group - the range most people fall into.
2. Start low - closer to 10 than 20, especially as a beginner. Volume is a resource you add gradually.
3. Count only working sets, taken close to failure (RIR 0-3), and account for indirect work from compound lifts.
4. Split larger volumes across 2-3 sessions - fresher sets and more frequent stimulus beat cramming everything into one day.
5. Increase volume only when your current volume stops working, not because someone online does more.

Most important of all: these numbers mean nothing if you do not track them. Whether you use a notebook, a spreadsheet, or Pully - start counting weekly sets per muscle, stay in the range, and add volume with intent. It is one of the simplest changes that genuinely speeds up your results.
