What should i do? Please help!?

You should do a lot of cardio first to lose the fat. Then start to add in weight lifting, etc and eat more protein. Increase the amount and intensity of the chest exercises as you get better. Then, when you have your ideal body, keep the level of difficulty constant, unless your chest starts to get too big. Then you can decrease the amount and intensity a little bit, and it should get smaller pretty quickly. Good luck!
