The Claim

In young, resistance-trained men, increasing rest periods between sets from 1 to 3 minutes during an 8-week resistance training program results in significantly greater improvements in maximal strength for both the back squat and bench press.

Cause and effect
1 study reviewed
In plain English

Among young men who regularly lift weights, extending rest periods between sets from 1 to 3 minutes during an 8-week training program leads to larger increases in maximum strength for the back squat and bench press.

See the scientific wording

In young, resistance-trained men, increasing rest periods between sets from 1 to 3 minutes during an 8-week resistance training program leads to significantly greater improvements in maximal strength for both the back squat (15.2% vs. 7.6%) and bench press (12.7% vs. 4.1%), suggesting that longer rest intervals enhance neuromuscular recovery and training capacity in this population.

Why this might work

Longer breaks between sets let muscles fully recharge their energy stores and clear out fatigue chemicals, so each set can be done with maximum effort. This increases the force pulled on muscle fibers, which triggers signals that build more muscle and improve nerve control, leading to stronger lifts.

  1. Study: Longer Interset Rest Periods Enhance Muscle Strength and Hypertrophy in Resistance-Trained Men

    For guys who already lift weights, taking 3 minutes of rest between sets instead of 1 minute helped them get stronger faster on squats and bench presses over 8 weeks.
