yeah, i have heard of it before... P90X stands for Power 90 Extreme Workout.
its 3 months of killing yourself everyday. The workouts you do everyday are not slow burns, they are really hard on you. It's a max out type thing. Some people don't even qualify to be fit enough to take P90X and have to just do P90.
I'm going to start it in February, I think, haha
