Push Up Streak is a core-exercise tracking app for Android and iOS. There's a number of core exercise icons with customizable names and fully customizable daily, weekly and monthly targets. It also has automatic counters for pushups, squats and situps within the phone app. This watch companion app allows you to log reps down the gym or out on a run without the need to have your phone present. When the watch next syncs with your phone the reps are uploaded to the main app.

Activate Garmin watch sync within the General Settings of the Android / iOS app.  Watch sync is a PREMIUM app feature, with a free trial period.

Background sync added so app only needs to be open on the phone to sync activities with the watch.  Watch now shows current set which auto-increments after 1 minute.
