i've heard some good things about p90x. never tried it out myself. just wondering, does p90x use any of the barbell exercises? especially the 3 powerlifts: squat, bench, deadlift. looks interesting though, most traditional workouts have you working out every part of your body every week, except on break weeks, p90x has you doing a body part about 1/2 of the total 11 or 12 weeks.
P90X is the sh*t, that stuff will kick your ass and make you look great.
If I could afford it, and if I had enough space in my house, and if I had a pair of matching dumbbells, and if I had a pull up bar, I would do the P90X. But I'm going to a university this fall, I'll see what I can do then.
