Rating of Perceived Exertion
The Perceived Exertion and Talk Test Chart provides an easy way to tell if you are training in the correct heart rate zone without actually taking your heart rate. In simple chart format, it uses different factors to determine your intensity level, including how difficult it is to talk while exercising and your perception of how hard you are working. Use this chart to become more in tune with your body while exercising and boost your overall fitness level.
RPE is often used by group fitness instructors to help participants self monitor their exercise intensity level. It is also used by those on medications that can influence heart rate.
