Borg Rating of Perceived Exertion Scale

The Borg Rating of Perceived Exertion Scale or RPE scale is a self-report tool to measure the amount of effort needed to do a particular activity.

Theory
The scale scores perceived effort from 6 (no effort at all) to 20 (absolute maximum, exhaustion). Fitter people feel like they are putting in less effort than less fit or deconditioned people who are doing the same activity.

Evidence
The World Health Organization has suggested using the RPE scale to assess effort when covering from COVID-19.

Cost and availability
The RPE scale is free to use and readily available.
