Whoa, calm down strongman before you blow your ass out from all of that intense squatting. You're right, this IS an MMA forum. I don't care if you're a powerlifter and P90X is a bitches routine in your eyes. It is still an MMA based forum and I am giving my opinion on what I think is an overlooked program(again, mostly in the flexibility area). Squating, deadlifting, and being a jackass are all perfectly fine. So is talking about something that doesn't necessarily involve those things but is still good.
Anyway, I also think I'll point out that while the Legs/Back routine in P90X is good, it wouldn't be a bad idea to add in legitimate squats if you have access to a rack at your house.
