Unified Training Status
When you use more than one Garmin device with your Garmin Connect account, you can choose which device is the primary data source for everyday use and for training purposes.
From the Garmin Connect app menu, select Settings.
Primary Training Device: Sets the priority data source for training metrics like your training status and load focus.
Primary Wearable: Sets the priority data source for daily health metrics like steps and sleep. This should be the watch you wear most often.
TIP: For the most accurate results, Garmin recommends that you sync often with your Garmin Connect account.
