The Claim
Individuals performing resistance exercise underpredict the number of repetitions remaining until task failure by an average of 0.95 repetitions, with substantial variability across individuals and conditions, indicating a consistent systematic error in self-assessment of exertion during strength training.
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.
During strength training, people consistently estimate they have more repetitions left than they actually do, with an average error of 0.95 repetitions, regardless of individual differences or training conditions.
See the scientific wording
Individuals performing resistance exercise tend to underpredict the number of repetitions remaining until task failure by an average of 0.95 repetitions, with substantial variability across individuals and conditions, indicating a consistent systematic error in self-assessment of exertion during strength training.
As muscles tire during lifting, signals from the muscles and nerves become less clear, so the brain misreads how close the body is to stopping, causing a person to think they are more tired than they actually are.
What the research says
1 studyWhen people lift weights and guess how many more reps they can do before quitting, they usually think they’re closer to giving up than they really are—by about one rep on average. This study checked lots of people and found the same pattern: everyone tends to guess too low.
