You don't get to redefine "workout" as you see fit. In the context of Apple Watch, a Workout is brief period of concentrated exercise.LOL, don't tell me I can't track my physical activity building a house as a workout for the week I'm doing it. Hauling roofing shingles up a ladder isn't a workout?
If you work outside moving crap around, no thats not a workout in the context of Apple Watch. Set your move goal appropriately and Apple Watch will be be tracking your normal activity.
