I don't do a lot of
sport sport, though I'd love to go running and cycling more.
I'm a dancer (I'm not sure if that counts on this thread

), and I have regular rehearsals so I don't do a lot of sport outside that. I know a particularly murderous choreographer that has us doing a plank for about five minutes every rehearsal, plus push-ups and squats so I'm quite strong from that!
I mostly work on flexibility, though - I stretch every day, even when I'm not in a show, because it's so easy to lose my splits (I'm not naturally bendy). Dance/workout games are always great fun as well.
