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 

(

Heart Rate Zone Calculations

, page 16

) 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.
