SmartGymApp
Improve workout support by recognizing strength training metrics such as total volume, sets, reps, estimated 1RM, muscle groups trained, and weekly training load from apps like SmartGym, and others.
SmartGymApp is a strength training app for iOS. Not possible as this app does not make any of its data available to users by API or by writing its metrics to Apple Health, as far as I can tell.
