The Claim

Training to momentary muscular failure with drop sets may result in greater muscular performance gains compared to training to a self-determined repetition maximum without reaching failure, even when total training volume is lower, indicating that intensity of effort could be a more critical determinant of strength adaptation than volume.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Working muscles to complete fatigue using drop sets might lead to better strength gains than stopping before full fatigue, even if you do fewer total repetitions, suggesting that how hard you push may matter more than how much you do.

See the scientific wording

Training to momentary muscular failure with drop sets may lead to greater muscular performance gains than training to a self-determined repetition maximum without reaching failure, even when total volume is lower, suggesting intensity of effort may be a more critical determinant of strength adaptation than volume.

Why this might work

When you push your muscles until they can't move the weight anymore, and then lower the weight and keep going, your body is forced to use more muscle fibers than usual. This forces your brain to send stronger signals to those fibers, and over time, your muscles learn to use more of their fibers at once, making you stronger—even if you didn't do as many total reps.

    This study found that lifting weights until you can't do another rep, even if you do fewer reps total, leads to better strength gains than doing more reps but stopping before exhaustion. So, going all-out matters more than doing more reps.
