The Claim

In recreationally trained young men, resistance exercise performed to muscular failure results in a higher internal training load, as measured by session-rated perceived exertion (RPE), compared to non-failure resistance exercise when training volume is equalized.

What the research says

Supports is higher

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.

Cause and effect
1 study reviewed
In plain English

If you lift weights until you can't do another rep, your body feels like you worked harder than if you stopped before failure—even if you did the same total number of reps and sets.

See the scientific wording

Training to failure during resistance exercise results in higher internal training load (as measured by session RPE) than non-failure training with equalized volume in recreationally trained young men.

  1. Study: Acute effects of equated volume-load resistance training leading to muscular failure versus non-failure on neuromuscular performance

    When people lift weights until they can't do another rep, their bodies get more tired than when they stop before failure—even if they do the same total amount of lifting. This study shows that failure training leaves you more drained for much longer, which means it feels harder and puts more stress on your body.
