How long should you rest between sets?

Short answer
Rest 2–3 minutes on compound lifts and 1–2 minutes on isolation exercises. Longer rest preserves performance in the next set. For hypertrophy, rest beyond 90 seconds adds little on average.
Figures
- 2–3 min · compound lifts
- 1–2 min · isolation exercises
- 3 vs 1 min · more strength with 3 min (Schoenfeld 2016)
- 1.5 minutes of rest between sets: 90 s: longer rest added little extra muscle on average (Singer 2024)
- 3 minutes of rest between sets: 3 instead of 1 min: more strength gain in trained men (Schoenfeld 2016)
What the studies show
Schoenfeld and colleagues had trained men lift for 8 weeks with 1 or 3 minutes of rest. The 3-minute group gained more strength and, in some measures, more muscle. The meta-analysis by Singer and colleagues found little extra growth beyond 90 seconds.
Extend rest when needed
Start the next set once your breathing and focus are back. On squats or deadlifts that often takes more than 3 minutes. Rest that is too short costs reps and therefore volume.
Keep sessions comparable
When you compare progress, keep rest similar. Fewer reps at the same load after shorter rest are not a regression.
