What is RPE, and how do you actually use it?

RPE stands for rate of perceived exertion. In lifting it runs 6 to 10 and it is based on reps in reserve: how many more you could have done. An RPE 8 means about two left. You use it to decide when to add weight and when to hold, so the load tracks what you can do that day.
