I'll do strength training in my dressing room between shoots, and I've been known to make business calls while out jogging. I try to mute myself on Bluetooth so they can't hear me huffing and puffing, but I usually end up getting caught.

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.
