The Claim

In resistance-trained males with over one year of experience, inter-set rest intervals greater than 60 seconds result in modestly greater improvements in strength compared to inter-set rest intervals less than 60 seconds, with a pooled standardized mean difference of -0.74, due to enhanced neuromuscular recovery and load maintenance enabling higher force output across sets.

Cause and effect
1 study reviewed
In plain English

Among experienced male resistance trainers, resting more than 60 seconds between sets leads to greater strength gains than resting less than 60 seconds, as measured by standardized performance differences.

See the scientific wording

In resistance-trained males with over one year of experience, inter-set rest intervals greater than 60 seconds likely result in modestly greater improvements in strength compared to intervals less than 60 seconds, with a pooled standardized mean difference of -0.74, suggesting that longer rest periods enable higher force output across sets by supporting neuromuscular recovery and load maintenance.

Why this might work

When someone lifts heavy weights, their muscles use up energy quickly. If they wait more than a minute between sets, their muscles rebuild the energy they used, which lets them activate the strongest muscle fibers again in the next set. This lets them lift heavier weights each time, which makes them stronger over time.

  1. Study: Investigating the Impact of Less Than or Greater Than 60 Seconds of Inter-Set Rest on Muscle Hypertrophy and Strength Increases in Males with >1 Year of Resistance Training Experience: Systematic Review with Meta-Analysis

    For experienced weightlifters, taking more than a minute of rest between sets helped them get slightly stronger than taking less than a minute, because their muscles and nerves had more time to recover and lift heavier weights.
