The Claim

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

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.

In plain English

Whether you push your muscles to complete exhaustion or stop a few reps short doesn’t change whether longer breaks between sets help you build more muscle.

See the scientific wording

Training to muscular failure or stopping short of failure does not meaningfully alter the relationship between inter-set rest interval duration and muscle hypertrophy in the arms or thighs, suggesting rest interval effects are independent of proximity to failure.

What the research says

1 study

  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

    Multivariate analyses of studies stratified by failure/non-failure showed nearly identical effect sizes for thigh and arm hypertrophy across both conditions, with overlapping credible intervals and no statistically meaningful interaction.
