Why Volume Matters — and Why More Isn't Always Better
Volume — the total amount of work you do for a muscle group over a week — is one of the primary drivers of hypertrophy. More volume generally means more muscle growth, up to a point.
That point varies significantly between individuals, muscle groups, and training history. Go below it and you're leaving gains on the table. Go above it and you're accumulating fatigue faster than you can recover — which stalls progress, increases injury risk, and makes training miserable.
Finding the right volume for each muscle group is one of the most practically useful things you can do for your training.
The Research Framework: MEV, MAV, MRV
The clearest way to think about training volume comes from the work of Dr. Mike Israetel and the RP Strength team, who formalised a framework around three thresholds:
MEV (Minimum Effective Volume): The least amount of training needed to make progress. You'll gain muscle on this, but it's the floor, not the target.
MAV (Maximum Adaptive Volume): The volume at which you make the most progress relative to the recovery cost. This is where you want to spend most of your training time.
MRV (Maximum Recoverable Volume): The upper limit before recovery is compromised. Training here briefly is fine (during peak phases), but staying here long-term leads to overtraining.
Most lifters should train somewhere between MEV and MAV — closer to MAV when things are going well and recovery is high, closer to MEV during deloads or periods of life stress.
General Recommendations by Muscle Group
These ranges represent MEV → MAV for most intermediate lifters. Beginners often do well at the lower end; advanced lifters may need more.
| Muscle Group | Sets Per Week (MEV → MAV) |
|---|---|
| Chest | 10–20 |
| Back | 10–20 |
| Shoulders | 8–16 |
| Biceps | 8–14 |
| Triceps | 6–12 |
| Quads | 8–16 |
| Hamstrings | 6–12 |
| Glutes | 8–16 |
| Calves | 8–16 |
| Abs | 8–16 |
Important caveats:
These are *direct* sets. Compound exercises also provide indirect stimulus — your triceps get volume from bench press, your biceps from rows, your rear delts from any horizontal pull. Factor this in or you'll over-programme.
These are also weekly totals across all sessions, not per-session recommendations. 16 sets of chest per week might be 8 sets on Monday and 8 on Thursday.
What Does a "Set" Count As?
For volume purposes, count any set taken to or within 1–3 reps of failure, with a weight that genuinely challenges you in the target rep range (typically 6–20 reps for hypertrophy).
Sets done far from failure with very light weight don't count. Warm-up sets don't count. Half-effort sets don't count.
Quality sets matter more than raw set count.
How to Find Your Own Optimal Volume
Generic recommendations are starting points, not prescriptions. Here's how to dial in volume for your own body:
Start at MEV. Begin a training block at the lower end of the range. This gives you room to add volume over the weeks as adaptation occurs.
Add sets progressively. Each week (or every two weeks), add 1–2 sets per muscle group if recovery is good and you're making progress. This is mesocycle progression — a structured way to build volume over time.
Watch for signs of MRV. You're likely approaching your maximum recoverable volume when: joints start feeling beat up, sleep quality drops, motivation tanks, and performance stalls despite adequate nutrition and sleep.
Deload when needed. After 4–8 weeks of building volume, take a deload week (reduce volume by 40–60%). This clears accumulated fatigue and often results in noticeable performance improvements in the following week.
Reassess between blocks. Your MEV and MAV change as you get stronger and adapt. What was plenty of volume six months ago may be maintenance volume now.
Frequency: How Often Per Week?
Evidence suggests most muscle groups respond best to 2 direct training sessions per week rather than 1. The same weekly volume (say, 16 sets of quads) produces better hypertrophy split across two sessions than hammered in one.
3x per week per muscle group is supported by research as slightly better than 2x in some studies, but the difference is smaller and the practical trade-off (more training days, less recovery time) often makes 2x the more sustainable choice.
For most people: train each muscle group twice per week and distribute volume evenly across sessions.
A Practical Example: Intermediate Push Day
If you're targeting 14–16 sets of chest per week across two push sessions:
Session A (Monday):
- Barbell bench press: 4 sets
- Incline dumbbell press: 3 sets
- Cable fly: 2 sets
Session B (Thursday):
- Dumbbell bench press: 4 sets
- Incline cable press: 3 sets
That's 16 sets — split across two sessions, varied in exercise selection, all working the chest from slightly different angles. Add in triceps and shoulders and you have a full push day.
Tracking Volume to Optimise It
The problem most people have with volume optimisation is that they don't track consistently enough to see patterns. If you're logging workouts sporadically or not at all, you can't identify when you're under-recovering or under-stimulating a muscle group.
Good workout tracking — including RPE data — is what turns these guidelines from theory into practice. When you can see that your bench press RPE has been climbing for three weeks despite the same weight, you're likely approaching MRV and need a deload.
Soma tracks sets, reps, RPE, and volume per muscle group, and uses that data to inform your AI-generated programme adjustments. It's the difference between guessing at your volume and actually knowing it.
