This self-assessment helps individuals regulate their intensity levels, ensuring they are working within a safe and effective range for their fitness goals.

Using the RPE scale can be particularly beneficial because it is subjective and takes into account personal feelings and experiences during exercise, making it an adaptable tool for various fitness levels and conditions. For instance, someone who is new to exercising might feel a higher exertion level at a lower intensity than a seasoned athlete, and the RPE scale accommodates these differences.

While calculating maximum heart rate, measuring body temperature, and assessing muscular strength are important aspects of fitness, they do not relate to the subjective experience of how hard one feels they are working during exercise. Consequently, the main function of the RPE scale is to help individuals effectively manage their perceived exertion in
