moderate intensity minutes by analyzing your steps per

calculation of intensity minutes.
 Exercise for at least 10 consecutive minutes at a
moderate or vigorous intensity level.
 Wear your device all day and night for the most
accurate resting heart rate.

such as walking, running, biking, swimming, and elliptical
training, for at least 10 minutes. You can view the event

Heart Rate Features
The Forerunner device has a wrist-based heart rate monitor
and is also compatible with chest heart rate monitors. You
can view heart rate data on the heart rate widget. If both wrist-
based heart rate and chest heart rate data are available, your
device uses the chest heart rate data.
There are several heart rate-related features available in the
default widget loop.
Your current heart rate in beats per minute (bpm).
The widget also displays a graph of your heart rate for
the last four hours, highlighting your highest and
lowest heart rate.
Your current stress level. The device measures your
heart rate variability while you are inactive to
estimate your stress level. A lower number indicates
a lower stress level.
Your current Body BatteryTM energy level. The
device calculates your current energy reserves based
on sleep, stress, and activity data. A higher number
indicates a higher energy reserve.
The current saturation of oxygen in your blood.
Knowing your oxygen saturation can help you
determine how your body is adapting to exercise
and stress.
NOTE: The pulse oximeter sensor is located on the
back of the device.
Wrist-based Heart Rate
Wearing the Device
 Wear the device above your wrist bone.
NOTE: The device should be snug but comfortable. For
more accurate heart rate readings, the device should not
move while running or exercising.

motionless.
