Rate of Perceived Exertion Scale

The RPE (Rate of Perceived Exertion) scale is used to measure the intensity of your exercise. The RPE scale runs from 0 – 10. The numbers below relate to phrases used to rate how easy or difficult you find an activity. For example, 0 (nothing at all) would be how you feel when sitting in a chair; 10 (Maximal Effort) is how you feel at the end of an exercise stress test or after a very difficult activity.

0 – Nothing at all
0.5 – Just noticeable, could maintain indefinitely
1 – Very light- Easy to carry on a conversation, could maintain for multiple hours
2 – Light – Easy to carry on a conversation, could maintain for multiple hours
3 – Light – Conversational, could maintain for 2-3 hours
4 – Moderate- Shorter conversational, could maintain for 2-3 hours
5 – Moderate- Short conversational, could maintain for 1-2 hours
6 –  Upper moderate- Very short conversational, could maintain for 30-60 minutes
7 – Vigorous- Single sentences, could maintain for 15-30 minutes
8 –  Vigorous- Short phrases, could maintain for 5-15 minutes
9 –  Very Hard- Single words, could maintain for 1-5 min
10 – Maximal effort- No speaking, could maintain for no more than 1 min
