How are dumbbell exercises counted?
-iOS: You have the option to adjust how you would like your dumbbell exercises to be counted. If you go to the Profile tab > Settings > Bonus Options you'll find a "Count Dumbbells Twice" option. If you enable it, it will calculate the total volume for a workout, as well as the volume charts for that exercise. If you disable it, volume will not automatically be doubled.
-Android: All dumbbell exercises are automatically doubled
