Your Rate of Exertion (RPE) measures the rate of exercise intensity. The scale indicates the level of exertion from 6 (the level you feel at rest) to 20 (the level you feel at exhaustion). To benefit the most from your walking program, your exercise intensity should be "somewhat hard" to "hard" or 12 - 15 on the Borg Rate of Perceived Exertion Scale.
| RPE | Exercise Intensity |
| 6-8 | Very, very light |
| 9-10 | Very light |
| 11-12 | Fairly light |
| 13-14 | Somewhat hard |
| 15-16 | Hard |
| 17-18 | Very hard |
| 19-20 | Very, very hard |
