Target Heart Rate Calculator
Use the Target Heart Rate Calculator to determine the intensity of your exercise and the effect on your heart rate. You want to be sure to exercise at a safe rate and not overwork your heart.
Your heart rate is calculated by subtracting your age from 220; the result is your maximum heart rate. For most healthy people, the American Heart Association recommends an exercise target heart rate ranging from 50 to 75 percent of your maximum heart rate.
Remember that exercise is only one factor related to risk for disease. Consult your healthcare provider if you have questions or concerns about how your exercise can impact your health.
