Automatically Tracking Exercise
The SmartTrack feature automatically recognizes and records your runs and other
exercise for you, even when you forget. Whenever you wear your Fitbit Charge HR
and participate in any continuous, high-movement activity of 15 minutes or more,
including walking, running, outdoor biking, and elliptical, Fitbit Charge HR detects
your activity and automatically records it for you. When you sync your Fitbit Charge
HR, you’ll see your exercise summary on fitbit.com or in the Fitbit app. You can
adjust your SmartTrack settings to detect exercises and activities anywhere from 10-
90 minutes.
SmartTrack does not record more precise exercise stats. If you want to track a
specific exercise with precise stats, you should use exercise mode on your Fitbit
Charge HR.
