Using the RPE (Rate of Perceived Exertion) chart is important when completing a physical activity because it allows individuals to subjectively gauge their own exertion levels during exercise. This can help them monitor and control the intensity of their workouts, ensuring that they are working hard enough to see results but not pushing themselves to the point of injury or exhaustion. Additionally, the RPE chart can help individuals set appropriate goals, track their progress over time, and adjust their workouts accordingly.
