You don't have to go to the gym to bulk up. By bulking up I don't mean that you're trying to be Ms. Olympia but I'm guessing you mean you want to tone up, get some definition. There are physical strength excercises that will do just that without having to by weights, etc. Situps (tummy), squats and lunges (legs, thighs, butt), and push ups/pull ups (biceps, triceps, forearms). Turbo Jam DVDs are excellent for this.
If everyone here were in NY, we'd all be totally hanging out and making fun of everyone who just can't seem to get their act together and eat healthy!
