The Claim

Does training to failure change how rest intervals affect muscle growth?

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.

In plain English

Whether you push your muscles to complete exhaustion or stop a few reps short doesn’t change how much rest you need between sets to grow muscle.

See the scientific wording

The hypertrophic response to inter-set rest interval duration is not meaningfully altered by whether resistance training is performed to muscular failure or stopped short of failure, as effect sizes for both conditions are similar and confidence intervals overlap substantially.

  1. Study: Give it a rest: a systematic review with Bayesian meta-analysis on the effect of inter-set rest interval duration on muscle hypertrophy

    The study found that whether you push your muscles to complete exhaustion or stop a little earlier doesn’t change how much muscle you gain when you rest longer or shorter between sets — so the claim is right.
