The Claim

Training to failure in resistance exercise produces meaningful physiological adaptations only when performed at a high intensity, defined as a high percentage of one-repetition maximum, and when sufficient training volume and load are maintained; otherwise, adaptations are unlikely.

Cause and effect
1 study reviewed
In plain English

If you're lifting weights and want to see real gains, pushing yourself to failure only works if you're using heavy weights and doing enough sets and reps. If the weight or volume is too low, it probably won't help much.

See the scientific wording

Training to failure in resistance exercise is only effective when performed at a sufficiently high intensity, defined as a high percentage of one-repetition maximum, and is unlikely to produce meaningful adaptations if volume or load is inadequate.

What the research says

1 study
  1. Study: The application of training to failure in periodized multiple-set resistance exercise programs.

    The study says that pushing your muscles to failure during weight training only works if you're lifting heavy enough. If the weight or number of reps is too low, it won't help much.
