Perceived exertion
Getting to know your body is fundamental in understanding how it works, where it excels and ultimately where its limitations may lie. Despite all of the technology that’s available today, it’s important to learn from, and listen to, your body. After all, no one knows it as well as you do.
Perceived exertion is how hard you feel that your body is working and can be rated on a scale of 0-10, with zero being nothing at all and ten being very, very, heavy exertion. Although a simple means of judging your effort Rated Perceived Exertion (RPE) is an effective and low cost (it doesn’t get much cheaper than free) means of judging the effort that you’re putting in, but as it’s based on the ‘feel-factor’ it’s harder to use this measure alone to accurately monitor training and progression.
