Exercise heart rates for 66 year olds
Target heart rate
At 66, your heart rate for moderate exercise is about 77 to 107 bpm. For vigorous exercise, it's about 108 to 131 bpm.
Heart rate zones at 66
Your estimated maximum heart rate is 220 minus your age, or 154 bpm. For women, a second formula from a 2010 study (206 − 0.88 × age) gives 148 bpm at 66. The zones below use the first estimate.
| Zone | Heart rate |
|---|---|
| Light | Under 77 bpmUnder 50% |
| Moderate | 77–107 bpm50–70% |
| Vigorous | 108–131 bpm70–85% |
| Above target range | 132–154 bpmOver 85% |
| Above estimated maximum | Over 154 bpmOver 100% |
What it means
How your zones are set. Your zones are based on an estimated maximum heart rate of 220 minus your age, the same for women and men. This is the estimate on the American Heart Association target heart rate chart. Moderate exercise is 50% to 70% of that maximum, and vigorous exercise is 70% to 85%.
A second estimate for women. A 2010 study by Gulati and colleagues estimated a woman's maximum heart rate as 206 minus 0.88 times her age. We show that number for comparison. It doesn't change your zones.
Zones describe effort, not results. Moderate and vigorous describe how hard you're working. They don't promise any particular result from a workout.
How to check your heart rate during exercise
- Count the beats for 15 seconds, then multiply by 4.
- Compare that number with the zones for your age.
- Stop and get help if you have chest pain, feel faint or have trouble breathing.

Common questions
Short answers about how these calculators work.
Why isn't the women's estimate used for the zones? The American Heart Association target heart rate chart uses 220 minus age for everyone. We show the second estimate for women so you can compare the two.
Does being in a zone mean my workout is safe? No. A zone is an estimate of how hard you're working. Chest pain, fainting or trouble breathing needs medical help, whatever your heart rate.
