The Claim
Training to momentary failure (0–3 or 0 RIR) in trained men is associated with higher dropout rates and protocol deviations compared to submaximal training, indicating reduced feasibility and potential safety concerns.
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.
In trained men, lifting weights until complete muscle failure leads to more people quitting or deviating from the training plan, and raises more safety issues than lifting with some effort left in reserve.

Pushing muscles to complete exhaustion causes intense nerve and muscle fatigue, which overwhelms the brain's ability to keep sending strong signals to move. This makes the person feel like they can't continue, and their body starts losing control of movements, leading them to quit or perform the exercise incorrectly.
What the research says
1 studyIn the study, guys who lifted weights until they couldn’t do another rep quit or messed up their workouts more often than those who stopped a few reps short. This means training to failure is harder to stick with and may be riskier.
