School is over and i need to get into shape. I would like to get in shape within 2 months! I weigh 205 pounds and im 6 feet 1 inch tall. My belly sticks out like 2-3 inches(its groose)
I want to mainly lose my belly fat and man tits. Also i would like to gain muscle in my legs. As for my arms im just going to do push ups and lift some dumbbells.
