Introduction to the Workout Heart Rate Range
During workouts, the band will calculate your heart rate range based on your personal
information.
The heart rate range can help you understand the effect and intensity
of your workout.
The band will display your current heart rate range after the heart rate value.
When the workout finishes, you can view the workout duration of each heart rate range on the
“Details” page of the app's record for this workout.
The band provides six ranges by default:
The default heart rate range is calculated based on the estimated maximum heart rate. The band
calculates the maximum heart rate by deducting the age formula from the commonly used 220.
