Your target heart rate is what you should aim for when exercising to get the most aerobic benefit.
| Low: | 91-119 |
| Medium: | 120-137 |
| High: | 138-155 |
| Very High: | 156-173 |
| Maximum: | 174-183 |
Target heart rate is only a guide. Each individual is different, so pay attention to how you feel, how hard you are breathing, how fast your heart is beating, and how much you feel the exertion in your muscles.
