The Claim

Repetitions in Reserve scale accuracy decreases as the number of repetitions increases during resistance training sets among adults, indicating that longer sets reduce the reliability of self-perceived effort estimation.

In plain English

When people do more reps in a row during weight training, they become worse at guessing how many more reps they could do. This means longer sets make it harder to judge your own effort accurately.

  1. Study: Factors influencing the accuracy of the repetition in reserve scale in resistance training: a systematic review

    The study found that when people do more repetitions in their workout sets, it becomes harder for them to accurately judge how many more reps they could do. This directly supports the claim that longer sets make it tougher to estimate effort.
