Female slave needs exercise tasks

Well you can get an exercise bike, replace the seat with a dildo. Make her use different holes at different times. Never allow her to sit. Make her squat. This will build up her legs quickly with tone.
Do you have or want to use one of those shocking toys? If you do I know a good many tasks for her to do that will tone her. But it won’t make her look like a huge body builder either.
Be looking to here from you.
