u/Importance_Typical

I just learned that Garmin, when you do a workout, it automatically knows where the muscle that you target is. So, for example, if you do bicep curls, they know exactly it's the biceps. But it seems like for Coros, you need to manually add it. If not, it will not detect it automatically. Why can't Coros do it? Is it because of hardware limitation, software limitation? What is it?
