Heart Rate Features
The vívoactive 3 device has a wrist-based heart rate
monitor and is also compatible with chest heart rate
monitors (sold separately). 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.
Wrist-based Heart Rate

• Wear the vívoactive 3 device above your wrist bone.

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.
