Well, I think I'll be happy with any results, so my goal is quite vague... I know that p90x will give me more muscles (which I'd like), but from what I understand, to a certain and lesser extent - Insanity will help me do that as well by losing fat.
Again, I'm not overweight, but I do have some fat I'd like to lose.
Also, I plan on doing it with a friend (havn't told him yet, LOL) and while hard as fuck from what I read in the past hour here on gaf, Insanity might be better for him since he needs some cardio workout.
As for nutrition, I'd like to think that other then the occasional sin, I eat quite well. Not amazing, but not shit. Usually a sandwich with cheese for breakfast (and egg on weekend), launch might be another sandwich, and dinner is some meat with either rice, pasta or potatos.
Maybe I eat too much bread, since somedays I eat around 6 slices. It's just the easiest thing to get while I'm at the university...
Thanks for the help
