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.
If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page 26) 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.

About Heart Rate Zones

Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their
level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart
rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
