How can i make my stomach flat ?
Plenty of healthy food / proper diet and some kind of fitness program, whether it be your own workout or a gym / fitness membership. Having a friend on the same program with you "buddy support system" will help assure the best results. Best of luck!
Oh I dont know...A diet?...Sticking your finger down your throat?...NO NO DONT TRY THT LAST ONE! I never did and never will.
