Ha. Just kidding.
Sarah's treadmill dance workout
This girl has some great videos. Will give you an idea how to start. Get comfortable forward, practice some backwards, then put them together for a turn... get used to the sides and how to jump onto them when you lose balance.
I don't use the handholds or jump or do kicks like that. My ankles are already toast.
I had to put socks over my rubber soles to do spins.
I would recommend a longer track, hers is pretty short.
