What does an RPE of 13 indicate in terms of exercise intensity?

An RPE of 13, which stands for Rate of Perceived Exertion, indicates that the individual is experiencing what is termed "somewhat hard" exercise. This scale, typically ranging from 6 to 20, correlates with heart rate, offering a subjective measure of perceived exertion during physical activity. At an RPE of 13, a person feels challenged but can continue exercising for a sustained period, suggesting that the intensity is indeed elevated but still manageable.

Understanding the RPE scale is essential for tailoring workouts to individual fitness levels and goals. For instance, lower scores indicate lighter effort levels, while higher scores reflect more strenuous exertion. In this context, a score of 13 fits well within the "somewhat hard" category, distinguishing it from both easier and more strenuous workouts.
