The Claim
In advanced resistance-trained individuals, occasionally performing resistance exercise sets to muscular failure during short-term training phases may help overcome training plateaus by increasing motor unit activation and growth hormone release; however, training to failure is not essential for improving strength or muscle hypertrophy and may increase the risk of overtraining when used too frequently.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're an experienced lifter stuck in a plateau, doing some sets until you can't lift anymore might help you break through — but only if you do it once in a while. Doing it too much could lead to burnout or overtraining.
See the scientific wording
Performing resistance exercise sets to failure may help advanced lifters overcome training plateaus when used occasionally in short-term training phases, potentially through increased motor unit activation and growth hormone release, but it is not essential for gains in strength or muscle size and carries risks of overtraining if used too frequently.
What the research says
1 studyStudy: The application of training to failure in periodized multiple-set resistance exercise programs.
The study says going all the way to muscle failure during weight training can help experienced lifters get past plateaus if done occasionally, but doing it too much can lead to overtraining — just like the claim says.
