Re: Male, wanting to tone/reduce chest
Diet and cardio is what will get rid of the flab. You can't spot reduce (lose fat in only one place) so you'll have to work on losing fat all over, and the man-boobs will follow. To tone the muscle, doing bench presses, pec flys, pushups and such will help. Although I would recommend working out *all* of your muscles so you can maintain a symmetrical appearance for aesthetics and strength balance for functionality and to prevent injury. Not to mention, putting on muscle all over will help you lose fat all over throught raised metabolism.
