The Claim
In volume-matched resistance training programs among experienced men, higher intra-session set volume (5–6 sets) for compound lower-body exercises such as the barbell back squat is associated with greater ratings of perceived exertion (RPE) compared to lower intra-session set volume (2–3 sets), indicating that the distribution of sets within a session influences fatigue perception independently of total weekly training volume.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If experienced guys do more sets of squats in one workout—like 5 or 6 instead of 2 or 3—they’ll feel more tired during that session, even if their total weekly workout volume stays the same.
See the scientific wording
In volume-matched resistance training programs for experienced men, the number of sets performed per session for compound lower-body exercises like the barbell back squat influences perceived exertion, with higher intra-session set volume (5–6 sets) linked to greater RPE compared to lower intra-session volume (2–3 sets), suggesting that session structure affects fatigue perception independently of total weekly volume.
What the research says
1 studyStudy: Effects of training frequency on muscular strength for trained men under volume matched conditions
The study found that doing more sets of squats in one session made workouts feel harder, even if the total weekly work was the same, which supports the idea that how you spread out your sets affects how tired you feel.
