I wanna get like that

I am starting a good strict diet loose weight and then build muscle.
My friend was FAT in grade 9 and 10, and then since the summer of 10 and 11 hes been working out and now (since beggining of grade 12) hes honestly ripped like that, I am starting my diet all cardio and little weights now and weights like crazy after i loose 60 lbs, JUST need the will power like my buddy to do it! I need support! Hes crazy now though, he had no abs in march but now has a crazy 6 pack and so shows it off at the water park every chance he gets, I used to get more chicks then him but not any more damn, Gotta start RIGHT NOW, I wanna change for the better.
