I have off for almost 2 weeks from gym so i was worried about the same thing. My coach suggested I do some conditioning and stretching on my own at home. Nothing too hard, but enough to keep you from totally losing strength and flexibility. So what I've been doing is doing some workout stuff during TV commercials. I'll be sitting there watching TV, and when the commercial comes on I try to do as much as I can of a certain thing until the show comes back on. And then the next commercial break, something else. And so on. Not like your really doing anything during commercial breaks anyway. I usually do some V-ups and push-ups and something for legs, but you can do whatever you want to do if you don't like those (or do whatever you need to do). I've done that every other day, and on days when I'm not doing that I go running. But I actually like running so its not as much of a chore for me as it is for some other gymnasts but its still good for ya.
Let us know what u end up doing!
