The Claim

The total volume of resistance training (measured as sets performed) is a more consistent driver of muscle hypertrophy than proximity-to-failure, as no moderating effect of volume load or relative load was observed on the hypertrophy response when comparing training to failure versus training away from failure.

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

Doing more sets of weightlifting seems to build muscle more reliably than how close you get to failing on each set—whether you stop short or push to exhaustion doesn’t change the muscle growth much if you’re doing the same number of sets.

See the scientific wording

The total volume of resistance training (sets performed) appears to be a more consistent driver of muscle hypertrophy than proximity-to-failure, as no moderating effect of volume load or relative load was found on the hypertrophy response to failure vs. non-failure training.

1 study
  1. Study: Influence of Resistance Training Proximity-to-Failure on Skeletal Muscle Hypertrophy: A Systematic Review with Meta-analysis

    The study found that whether you lift until you can't do another rep or stop before that, it doesn't make much difference for muscle growth — what matters more is how many total sets you do.
