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.
The device has separate heart rate zones for running
and cycling. For the most accurate calorie data during
your activity, you should set your maximum heart
rate. You can also set each heart rate zone. You can
manually adjust your zones on the device or using your
Garmin Connect account.

About VO2 Max� Estimates
VO2 max. is the maximum volume of oxygen (in
milliliters) you can consume per minute per kilogram
of body weight at your maximum performance. In
simple terms, VO2 max. is an indication of athletic
performance and should increase as your level of
fitness improves.
On the device, your VO2 max. estimate appears as a
number and description.
On your Garmin Connect account, you can view
additional details about your VO2 max. estimate,
including your fitness age. Your fitness age gives
you an idea of how your fitness compares with a
person of the same gender and different age. As you
exercise, your fitness age can decrease over time.
