Unfortunately Apple Watch devices are kind of garbage as fitness trackers. They have good optical heart rate sensors but none of the other stuff really works well. For better or worse it's just not a use case that Apple cares about. If this matters to you then you might be better off with different smart watch from the likes of Garmin, Coros, Amazfit, etc.
