The Claim

When performing the same number of sets and repetitions at 80% one-repetition maximum, 3-minute rest intervals result in a higher volume load than 1-minute rest intervals due to enhanced recovery enabling maintenance of heavier loads across sets.

Cause and effect
1 study reviewed
In plain English

Using 3-minute breaks between sets allows lifters to maintain heavier weights across more sets compared to 1-minute breaks, resulting in a greater total volume of weight lifted when performing the same number of sets and repetitions at 80% of their one-repetition maximum.

See the scientific wording

Volume load is higher with 3-minute rest intervals compared to 1-minute rest intervals when performing the same number of sets and repetitions at 80% one-repetition maximum, due to greater recovery allowing for heavier loads to be maintained across sets.

Why this might work

Longer breaks between heavy lifts let muscles refill their energy stores and clear out waste products, so each next lift can be done with the same strength. Shorter breaks leave muscles tired and weak, so later lifts get lighter and total weight lifted drops.

  1. Study: Volume Load Rather Than Resting Interval Influences Muscle Hypertrophy During High-Intensity Resistance Training

    When people rest 3 minutes between heavy lifting sets, they can do more total weight over the whole workout than when they only rest 1 minute, because their muscles get more time to recover. This study showed that longer rests led to more muscle growth, which means people lifted more overall.
