Target Heart Rates

Aiming for 85%*[220-age]

Take your pulse on the inside of your wrist, on the thumb side. Use the tips of your first two fingers (not your thumb) to press lightly over the blood vessels on your wrist.
Count your pulse for 10 seconds and multiply by 6 to find your beats per minute. You want to stay between 50 percent to 85 percent of your maximum heart rate. This range is your target heart rate.

This table shows estimated target heart rates for different ages. Your maximum heart rate is about 220 minus your age.

AgeTarget HR Zone 50-85% Average Maximum Heart Rate, 100%

35 years 93-157 beats per minute 185 beats per minute
40 years 90-153 beats per minute 180 beats per minute
45 years 88-149 beats per minute 175 beats per minute
50 years 85-145 beats per minute 170 beats per minute
55 years 83-140 beats per minute 165 beats per minute

If your heart rate is too high, you’re straining. So slow down. If it’s too low, and the intensity feels “light” or “moderate/brisk,” you may want to push yourself to exercise a little harder.

During the first few weeks of working out, aim for the lower ranger of your target zone (50 percent) and gradually build up to the higher range (85 percent). After six months or more, you may be able to exercise comfortably at up to 85 percent of your maximum heart rate.
