Borg Rating of Perceived Exertion (RPE)

The Borg Rating of Perceived Exertion (RPE) is a scale used to measure how hard you feel your body is working during physical activity. It typically ranges from 6 to 20, where lower numbers mean light effort and higher numbers indicate very strenuous effort. The scale helps individuals gauge their exercise intensity based on personal feelings of effort, breathlessness, and muscle fatigue, allowing for self-regulation without needing equipment. It is widely used by athletes and clinicians to monitor and adjust exercise intensity for safety and effectiveness.
