The Claim

Resistance-trained men who perform tri-set training experience a 56.0% increase in training efficiency (volume load per minute) compared to those who perform traditional training with longer rest intervals.

In plain English

Resistance-trained men who use tri-set training methods complete more total weight lifted per minute than those using traditional training with longer breaks between sets.

See the scientific wording

Resistance-trained men experience a 56.0% increase in training efficiency (volume load per minute) when performing tri-set training compared to traditional training with longer rest intervals, indicating that tri-set protocols allow for greater work output in significantly less time.

Why this might work

When muscles are worked rapidly with almost no rest, waste products build up inside them, pulling water into the muscle cells and making them swell. This swelling activates signals that keep the muscle ready to work harder, allowing more weight to be lifted in less time.

    Doing three chest exercises one after another with almost no rest lets people lift more total weight per minute than doing the same exercises with long breaks in between — even if they lift less total weight overall, they do it much faster.
