If you're stuck doing bodyweight exercises, I recommend getting a weight-vest, pullup bar, and maybe some adjustable dumbbells (good for goblet/box squats and overhead presses). You can certainly get fit on an all-bodyweight regime, but you don't really get those juicy muscle growth hormones without getting under some serious weight.
