The Claim

In resistance-trained young adults, training to muscle failure results in a small but statistically significant increase in muscle hypertrophy compared to training that stops short of muscle failure, indicating that training to failure may enhance muscle growth in experienced lifters.

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're someone who already lifts weights regularly, pushing your muscles until they can't do another rep might help you grow slightly bigger muscles than if you stop before reaching failure.

In resistance-trained young adults, training to muscle failure produces a small but statistically significant increase in muscle hypertrophy compared to training that stops short of failure, suggesting failure may enhance muscle growth in experienced lifters.

What the research says

1 study
  1. Study: Effects of resistance training performed to repetition failure or non-failure on muscular strength and hypertrophy: A systematic review and meta-analysis

    The study found that for people who already lift weights regularly, pushing muscles to failure during workouts leads to a tiny but real boost in muscle growth compared to stopping before failure.
