A normal heart rate during exercise varies depending on age and fitness level, but generally falls within a target heart rate zone.
The University of Iowa Health Care provides the following target heart rate zones and average maximum heart rates, which can give you a good idea of what's normal:
Target Heart Rate Zone During Exercise
| Age | Target Heart Rate Zone (50-85%) | Average Maximum Heart Rate (100%) |
|---|---|---|
| 20 | 100 to 170 beats per minute | 200 bpm |
| 30 | 95-162 bpm | 190 bpm |
| 35 | 93-157 bpm | 185 bpm |
| 40 | 90-153 bpm | 180 bpm |
These ranges represent 50-85% of a person's maximum heart rate, which is a generally recommended range for exercise.
