The original Rating of Perceived Exertion (RPE) scale, developed by Gunnar Borg, is a tool used to measure the intensity of physical activity based on the individual's perception of exertion. On this scale, a rating of 19 corresponds to 'very hard' exertion. This level of intensity is typically described as being extremely challenging, where an individual feels they are exerting themselves to a significant degree and may find it difficult to continue for much longer without rest.

In contrast, the other options represent different perceived exertion levels: 15 indicates 'hard', 13 signifies 'somewhat hard', and 20 reaches the extreme level of exertion, often described as maximal effort. Each number on the RPE scale allows both trainers and clients to communicate effectively about workout intensity and to ensure that exercise is conducted safely and effectively. Understanding the scale and its corresponding descriptions is crucial for personal trainers in designing appropriate and individualized workout programs.
