I got the P90x Plus discs as a bonus with mine. I haven't really checked them out yet. I will, though. It's definitely a tough program.

There's some pretty damn impressive transformations. This guy was a 370-pound lard ass and dropped 180 pounds in a year and a half and is cut up. His first round he lost 60 pounds, and about another 60 on round two.

This guy was also a total lard ass and after a year on the program is ripped and has BF in the single digits.
