I wouldn't go and try and get yourself a six pack thinking that it will make her fall for you. Just don't act like you are inferior to her, act like your still the man in charge, and her age doesn't have an effect on you. A big chest, six pack, and more height isn't gonna get you this girl if you don't got your game straight. She ain't gonna look at your six pack and be like "OMG you have a six pack **** me!!", cause every other guy shes seen probably has one too. So don't wait the whole summer n ****, or she will be either taken or your chance will be gone to get with her. Lay that game down and stil try and get six pack and stuff, but don't depend on that stuff to get you the girl. Good luck
