Hey everyone I am a new user and this is my first post. I just began to lift again this month. I am 18 years old, around 6'2 and about 200lbs. I am not sure of my exact body fat percentage but i think it is around 17%. I am not noticeably chubby, but you can notice it w/o a shirt. I want to lose my fat and gain muscle. I want to lose my man boobs and turn my semi gut into a 6 pack. I was told to do all of my exercises between 12-15 reps, to interval running and not eat fatty things. Is this the right approach, and does anyone know of any good exercises? I apologize if this post is rather lengthy.
