The Claim
Individuals performing resistance exercise can accurately estimate repetitions to failure when near failure, with average estimation errors of approximately 1 repetition for actual repetitions to failure between 0-5, compared to errors exceeding 2 repetitions for actual repetitions to failure between 7-10.
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 are lifting weights and getting really tired, they're pretty good at guessing how many more reps they can do if they're almost done—only off by about one rep. But if they could do a few more, their guess is less accurate, off by more than two reps.
See the scientific wording
People performing resistance exercise can accurately estimate repetitions to failure when they are close to failure, with estimation errors averaging approximately 1 repetition when the actual repetitions to failure are between 0-5, compared to errors exceeding 2 repetitions when actual repetitions to failure are between 7-10.
What the research says
1 studyStudy: Accuracy in Estimating Repetitions to Failure During Resistance Exercise
The study directly tested whether people can guess how many more reps they can do during weightlifting and found they're very close when almost exhausted, just like the claim says.
