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.

About Lifetime Athletes

A lifetime athlete is an individual who has trained intensely for
many years (with the exception of minor injuries) and has a
resting heart rate of 60 beats per minute (bpm) or less.

Setting Your Power Zones

The values for the zones are default values and may not match
your personal abilities. If you know your functional threshold
power (FTP) value, you can enter it and allow the software to
calculate your power zones automatically. You can manually
adjust your zones on the device or using your Garmin Connect
account.

Activity Tracking

The activity tracking feature records your daily step count,
distance traveled, intensity minutes, floors climbed, calories
burned, and sleep statistics for each recorded day. Your calories
burned includes your base metabolism plus activity calories.
The number of steps taken during the day appears on the steps
widget. The step count is updated periodically.

Auto Goal

Your device creates a daily step goal automatically, based on
your previous activity levels. As you move during the day, the
device shows your progress toward your daily goal
