Taking a little longer break between sets of weightlifting (more than a minute) might help your arms and legs grow slightly bigger, but the difference is so small it might not even matter in real life.

Give it a rest: a systematic review with Bayesian meta-analysis on the effect of inter-set rest interval duration on muscle hypertrophy

Systematic Review With Meta-Analysis
Human

The common advice to rest only 30–90 seconds between sets to build muscle might need updating — longer breaks (over a minute) seem to help a little, but not enough to be sure it’s worth changing your routine.

If you rest longer between weightlifting sets (2.5 minutes instead of 1 minute), your arms grow bigger over 10 weeks — even if your strength doesn’t change.
