Interpreting the Results
The displayed target heart range is a guideline for people in good health at your age. It should not be used if you're taking heart medication or suffering from asthma, heart disease, or hypertension. If you are under medical care or are beginning a fitness program, consult your health-care professional first.

During exercise, you can measure your heart rate from your wrist or neck. See the illustrations on the results page for more information.

The target heart rate calculator is not applicable to children. Their maximum heart rates can approach 200 beats per minute. Healthy children do not need to restrict activity for cardiovascular reasons.
