When you're working on building out your CoachMePlus Programs, you may want to use an Exercise that has Properties that you don't need at the moment, or even add ones on that weren't originally there. Simply just add or remove the different components as needed.
You can only change the properties of a pre-existing exercise from within the Program or Circuit, not in the Library after the exercise is created. It cannot be changed in the library to protect the integrity of past workout data and to protect old Completion Reports.
New exercises can have those properties edited while the exercise is initially being created.
