The session-RPE (rating of perceived exertion) gives you the possibility to reflect your subjective feeling of stress after each session. This evaluation should be given without much thinking and directly after the session.
From a scale of 1-10, developed by Forster et al (2001), you can indicate how strenuous you found the session. This information will help us to individually tailor your next training sessions in order to avoid under- or overtraining or even injuries.
The scale has been designed to accommodate the exponential increase in heart rate during a workload.
If you have forgotten to enter the intensity after a session, this session is automatically described with an RPE of 5.
