RPE (Rate of Perceived Exertion)
Definition: A self-reported scale (typically 1-10) measuring how hard a set felt. RPE 7 = could do 3 more reps, RPE 8 = 2 more, RPE 9 = 1 more, RPE 10 = failure. Used to auto-regulate training intensity.
Detailed Explanation
Rate of Perceived Exertion (RPE) is a subjective scale from 1 to 10 used to measure workout intensity. RPE 10 represents absolute failure, while RPE 8 means you have 2 reps in reserve.
Practical Application & Guide
Use RPE to auto-regulate your training. If you feel exhausted, adjust the weight down to hit the prescribed RPE target instead of forcing a predetermined number.
Common Pitfalls & Mistakes
Misjudging your proximity to failure. Most beginners underestimate their capacity, rating a set as RPE 9 when it was actually RPE 7.
