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 7) 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.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your default heart rate zones. You can set
separate heart rate zones for sport profiles, such as running,
cycling, and swimming. For the most accurate calorie data
during your activity, set your maximum heart rate. You can also
set each heart rate zone and enter your resting heart rate
manually. You can manually adjust your zones on the device or
using your Garmin Connect account.
