The Claim

In resistance-trained individuals, training with cluster sets does not produce greater total training volume than traditional sets when both protocols are matched for repetitions in reserve (0–1), and this equivalence persists over an 8-week training period.

In plain English

Among people who regularly lift weights, using cluster sets with short rests between reps does not lead to more total weight lifted over time compared to traditional sets, as long as both methods leave the same number of reps in reserve.

See the scientific wording

In resistance-trained individuals, training with cluster sets does not result in greater total training volume than traditional sets when both are performed with matched repetitions in reserve (0–1), suggesting that intra-set rest does not enable higher cumulative load in trained individuals over an 8-week period.

Why this might work

When muscles are pushed to near failure, nerve signals to the muscles weaken and muscle fibers tire out so much that no amount of short breaks between reps can restore enough strength to lift more total weight over time.

    Even when lifters take short breaks between reps in cluster sets, they don’t end up lifting more total weight over time than those who do regular sets—both methods lead to the same muscle growth when done equally hard.
