Training volume per muscle: MEV, MAV and MRV
Volume — the number of effective sets per week per muscle group — is the main driver of hypertrophy once intensity and technique are in place. You still need to know how much to aim for.
What is an "effective set"?
Count the working sets taken close to failure (about 0 to 4 reps in reserve), on an exercise that really loads the target muscle. Warm-up sets do not count. A compound exercise counts for the muscles it strongly involves: a bench press counts for the chest, and partially for the triceps and shoulders.
The three landmarks: MEV, MAV, MRV
- MEV — minimum effective volume. Below it, the muscle does not get enough stimulus to progress. This is the floor.
- MAV — maximum adaptive volume. The range where most lifters progress best over time. This is where you want to spend most of your training.
- MRV — maximum recoverable volume. Beyond it, fatigue builds faster than you recover: progress stalls or goes backwards. This is the ceiling.
Ballpark figures (weekly sets per group)
These values vary with the individual, training age, sleep and nutrition — use them as a starting point, not as absolute truth.
- Chest: MEV ~8, MAV ~12–18, MRV ~22
- Back: MEV ~10, MAV ~14–20, MRV ~25
- Shoulders (delts): MEV ~8, MAV ~16–22, MRV ~26
- Biceps / triceps: MEV ~6, MAV ~10–16, MRV ~20
- Quads: MEV ~8, MAV ~12–18, MRV ~20
- Hamstrings: MEV ~6, MAV ~10–14, MRV ~16
- Glutes: MEV ~4, MAV ~8–14, MRV ~16
- Calves: MEV ~8, MAV ~12–16, MRV ~20
How to adjust in practice
- Start a training block around your MEV (or slightly above).
- Add 1 to 2 sets per group per week as long as you progress (load or reps) and recover well.
- When progress stops, sleep gets worse or soreness lingers, you are approaching your MRV.
- Then take a deload week (volume halved, loads around 60%) and restart lower.
Spreading volume over the week
Beyond about 8 to 10 weekly sets for a group, it is better to spread them over 2 or more workouts: the quality of the last sets drops when you stack too many in one session, and muscle protein synthesis responds well to training each muscle twice a week.
PrimeFeat automatically calculates your weekly volume per muscle from your sets and places it against these landmarks, with the recovery status of each group.
