RPE (rating of perceived exertion)

RPE is an effort scale where RPE 10 equals failure (0 repetitions in reserve).

Also known as: Rating of perceived exertion · Perceived effort

In strength training, RPE is usually tied to RIR: RPE 8 corresponds to about 2 reps in reserve, RPE 9 to about 1.

Using RPE helps keep intensity consistent even when strength fluctuates because of sleep, nutrition or fatigue.
