The Claim

Based on a meta-analysis of longitudinal studies in adults, when training volumes are not equalized, resistance training not performed to failure produces greater strength increases than training to failure, with a standardized mean difference of -0.34 (p = 0.048).

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.

Quantitative

In plain English

When people lift weights without pushing to their absolute limit, they actually get stronger faster than if they push to failure, as long as the total amount of lifting isn't the same. This comes from a big review of studies on adults.

What the research says

1 study
  1. Study: Effects of Resistance Training Performed to Failure or Not to Failure on Muscle Strength, Hypertrophy, and Power Output: A Systematic Review With Meta-Analysis.

    The study found exactly what the claim says: when training volume isn't equal, not pushing to failure gives better strength gains than pushing to failure, with the same numbers.
