What level of exercise intensity does an RPE of 15 represent?

An RPE, or Rate of Perceived Exertion, is a subjective scale used to measure exercise intensity based on how hard an individual feels they are working. The scale typically ranges from 6 to 20, with lower numbers indicating easy intensity and higher numbers indicating more challenging efforts.

A rating of 15 on this scale corresponds to a "hard" level of intensity. At this level, individuals are likely to be experiencing significant exertion, characterized by a rapid heartbeat and noticeable fatigue. They can still maintain the exercise for a period, but it requires considerable effort and may not allow for prolonged conversations.

Understanding the RPE scale can help individuals gauge their workout intensity and facilitate better training decisions. The "hard" level signifies that while exercise is challenging, it is still within the capabilities of most individuals, particularly those who are accustomed to regular physical activity. Recognizing this intensity can aid in setting goals and tracking progress in a fitness regimen.
