Is it possible for me to lose weight? i promise ill choose a best answer!?

First off, taking prednisone is no fun! I took it and blew up like a balloon, it is the medicine, so try not to freak! Also sit ups really do nothing for you, and push ups aren't all that great of a way to tone yourself. If you want to tone yourself or lose those few extra pounds, the best thing you can do for yourself is run, or swim! Those are great ways to get in shape. But please don't cut back on your diet to much, because that could be bad for you, seeing as though you are only 13.
