The Claim

In recreationally trained adults, traditional-set bench press training results in greater velocity loss during sets than cluster-set training, with a large effect size (g = 1.50), indicating that cluster-set training reduces neuromuscular fatigue accumulation under conditions of equivalent training volume.

Cause and effect
1 study reviewed
In plain English

When recreationally trained individuals perform bench presses, using cluster sets leads to less decline in movement speed during a set compared to traditional sets, even when the total amount of work is the same, suggesting cluster sets may limit the buildup of neuromuscular fatigue.

Why this might work

When you do bench presses with short breaks between reps, your muscles don't get as tired during the set, so your nerves can keep telling your muscles to contract strongly. Without those breaks, your muscles get worn out faster, your nerves can't activate them as well, and your movement slows down. The short breaks let your muscles recover just enough to keep pushing hard, so you don't lose speed or power as much.

  1. Study: Effect of Set-Structure on Upper-Body Muscular Hypertrophy and Performance in Recreationally-Trained Male and Female

    When people do bench presses with tiny breaks between each rep, they don’t get as tired during the set as when they do all reps back-to-back—even if they lift the same total weight. This study proved it with hard measurements.
