This study looked at whether taking longer breaks between weightlifting sets helps muscles grow more, and it found that resting more than a minute might help a little, especially for arms and thighs — but resting longer than 90 seconds doesn’t help any more. This supports the idea that current rest time recommendations might need a tweak.
