now that exams are over i've decided to join a gym and get rid of the extra 15 pounds i gained. i was wondering what the best way is to lose this gut and get some abs....also, what types of excersices are good for gaining and which ones are good for definition?

any help is appreciated

ps: if u suggest a certain excersice, try to post some kind of visiual aid so i know how to do it.....i hate written instructions.
