For over a decade at StrongFirst, we have advised against pushing sets to failure and advocated always keeping a few reps “in the tank.”
In recent years, we have heard more and more often from well-known strength coaches and on the web about the Rate of Perceived Exertion (RPE) and Reps in Reserve (RIR).
It seems like many are finally coming to the conclusions we came to a long time ago. In fact, these are the conclusions that many Soviet sports scientists reached in the late 1900s, which we have endorsed and implemented in our system.
But what are RPE and RIR all about? |
