I have my guy Semi who is my on the road - he's my personal trainer. He helps me out with training and stuff like that, and he's shown me a lot of things I can do on the road. We were trying to figure out something that I can do everywhere, like in my hotel room, so I don't have to have a gym.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
