calculated based on percentages of your maximum heart rate.
Fitness Goals
Knowing your heart rate zones can help you measure and
improve your fitness by understanding and applying these
principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
• Knowing your heart rate zones can prevent you from
overtraining and can decrease your risk of injury.
If you know your maximum heart rate, you can use the table

) to determine the best
heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the
calculators available on the Internet. Some gyms and health
centers can provide a test that measures maximum heart rate.
The default maximum heart rate is 220 minus your age.
