Training volume

Training volume: what is it?

Volume is the dose of training. Intensity decides how hard each set is; volume decides how many of those sets a muscle gets. Almost every programming decision, adding an exercise, moving from three sets to four, planning a deload, is really a decision about volume. The difficulty is that "volume" gets counted several different ways, and the counting method changes what the numbers mean.

Hard sets per muscle per week

The most practical unit for hypertrophy programming is the number of hard sets a muscle receives in a week. A hard set is a working set taken close to failure, roughly RPE 7 or harder. Warm-ups do not count, and a set stopped at RPE 5 counts as much less than one at RPE 9. Counting this way makes programs comparable across exercises and rep ranges: 4 sets of 6 on a squat and 4 sets of 15 on a leg press both add 4 sets to the quads.

Widely used coaching ranges put most trained clients between about 10 and 20 hard sets per muscle per week, with beginners responding to less and advanced lifters sometimes tolerating more for a limited period. Those are starting points to adjust from, not targets to hit.

Volume landmarks

The landmark model gives coaches a vocabulary for adjusting volume per client. The minimum effective volume is the lowest weekly set count that still produces progress. The maximum recoverable volume is the highest the client can recover from before performance drops. Between them sits the range where most productive training happens. A mesocycle typically starts near the low end and adds sets week to week until recovery signs appear, then a deload resets the count.

Counting rules

Two questions decide how a set is counted. First, which muscles get credit: a compound lift usually counts as a full set for its primary mover and a partial set (often half) for secondary muscles, so a row counts fully for the back and partly for the biceps. Second, was the set hard: only sets near failure count in full. Being consistent matters more than which convention you pick, because volume is compared across weeks for the same client.

• Count working sets only; warm-ups and technique sets are excluded.
• Give full credit to the primary muscle, partial credit to synergists.
• A set at RPE 5-6 is not a hard set; do not count it as one.
• Track per muscle group, not per workout, or a leg day hides an underworked back.

Tonnage versus sets

Tonnage, sets multiplied by reps multiplied by load, is the traditional volume measure in strength sports. It is useful for tracking a single lift over time: if a client's weekly squat tonnage rises while reps and RPE stay steady, they are getting stronger. It is a poor way to compare muscles or exercises, because 100 kg on a leg press and 100 kg on a curl are not comparable work. For hypertrophy planning, count sets; for monitoring load on one lift, tonnage is a good complement.
