Definitely indoor exercise. See if you can do the 100 pushups a day challenge, and maybe look on craigslist and see if you can find things like pullup bars, weight vests, and dumbbells on the cheap.
I don't know how you feel about cooking, but I find it to be a good stress reliever. If you're bored, try doing some prep work like chopping onions, mincing garlic, parboiling sweet potatoes, cooking meats, etc. so you have easier access to meals later on.
