What is the range of numbers on the "regular" Borg scale for perceived exertion?

The regular Borg scale, which is used to measure perceived exertion during physical activity, has a range of numbers that goes from 6 to 20. This scale was designed to correlate with the physiological exertion levels typically experienced during exercise.

Each number on the scale represents a level of effort, with a score of 6 corresponding to no exertion at all and a score of 20 indicating maximal exertion. The design of the scale effectively allows individuals to communicate their perceived level of effort in a way that can be easily related to heart rate. For instance, a Borg score of 12-13 generally corresponds to a moderate level of exertion, while scores above 16 indicate a higher level of intensity.

Understanding this scale is critical for fitness professionals in order to gauge participants' exertion levels during workouts, making adjustments to intensity accordingly. The other options do not reflect the standard Borg scale for perceived exertion and would not provide the appropriate framework for assessing exercise intensity.
