Now youâre ready to determine your target training heart rate. As you exercise, periodically: 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. Know Your Numbers
Calculate your pulse. Note or remember how many heartbeats you counted. Your pulse rate is measured in beats per minute. For example, if you counted 41 for 30 seconds, double it to get 82 beats per minute. If you counted for 10 seconds, multiply the beats counted by 6, and if you counted for 15 seconds, multiply by 4.
