The Claim
Repetitions in Reserve scale accuracy during resistance training is greater when sets are performed closer to muscle failure, particularly in upper limb exercises, indicating that proximity to failure enhances perceptual accuracy in resistance training monitoring.
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.
When people lift weights until they're almost too tired to continue, especially with arm exercises, they get better at guessing how many more reps they could do. It's like training your body to feel its limits more accurately.
See the scientific wording
Repetitions in Reserve scale accuracy in resistance training among adults is greater when sets are performed at greater proximity to muscle failure, particularly during upper limb exercises, suggesting that closeness to failure enhances perceptual accuracy in resistance training monitoring.
What the research says
1 studyThe study looked at how well people can guess how many more reps they have left in weight training, and it found that when they lift weights until they're very close to failure, especially with arm exercises, their guesses are more accurate. This matches the claim exactly.
