how to calculate your target heart rate range
Hittinâ the Target. Now youâre ready to determine your target training heart rate. 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.
