The Claim

People who did more sets didn’t lift heavier weights—they just did more reps and sets. The weight stayed the same, but the total work went up.

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People who did more sets didn’t lift heavier weights—they just did more reps and sets. The weight stayed the same, but the total work went up.

See the scientific wording

Resistance training volume load increases significantly with progressive weekly set additions, but average training load per set remains unchanged across groups, indicating that volume differences are driven by set quantity, not intensity.

What the research says

1 study

  1. Study: Effects of Different Weekly Set Progressions on Muscular Adaptations in Trained Males: Is There a Dose–Response Effect?

    The study found that doing more sets each week made people stronger, but they didn’t lift heavier weights per set—so the extra strength came from doing more sets, not lifting harder.
