Heart Rate Zonesnotice

Consult your physician to specify heart rate zones/targets that are appropriate for your fitness level and health condition.

Many athletes are using 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 1–5 according to increasing intensity. The device sets the heart rate zone ranges (see the table on page 41) based on your maximum and resting heart rates set in your user profile (see page 26).

Using Accessories

You can also customize your heart rate zones in your user profile of Garmin Connect or Garmin Training Center. After customizing your heart rate zones, transfer data to your device.
