Rate of Perceived Exertion or RPE is a way of measuring physical activity intensity level. Perceived exertion is how hard you feel your body is working. It is based on the physical sensations a person experiences during physical activity, including increased heart rate, increased respiration or breathing rate, increased sweating, and muscle fatigue. It is rated as a number between 1 and 10.
Workout RPE Load
It is the Rate of Perceived Exertion times the duration it took to complete the Training Load. For example, if perceived exertion is 6 and the workout took 50 minutes to complete, the RPE Load would 300.
Workout Training Load
Training Load can be calculated as Sets X Reps X Weight. For example 4 sets of 6 reps of 75lbs would be 4 X 6 X 75lbs = 1800
The amount of time it took to complete a particular workout or set of exercises.
