Should I Join the Gym?!?

I'm 14 too, JOIN THE GYM! you wont regret it :P my gym has shows like biggest loser playing while working out, so I'll be doing elliptical for like two hours and listeining to music, magazines, whatever. at home you can be less motivated or trick yourself into not doing as much, and the gym clears your head more. I LOVE AB RIPPER! i might have huge hips but I actually have some really good abs from the p90x, i want to get the whole set one of these days. Oh and I'm not sure, but if your a girl (or you could be a guy but that could be weird...) I suggest zumba, great calories, and it's really fun. also no i dont believe that weight lifting will stunt your growth, I'm a long distance runner and I lifted, and I'm fine though yeah, I'm 5'2 so I'm not the best example. But think about it, what about those farm kids who are always lifting heavy items working all the time? Why in the world would it stunt your growth? Just be careful not to over train
