P90/x is insane. Its actually a good base system at the core, but all their 'success stories' come out looking freaking weird in my opinion.

Surprisingly enough, that keeps me from actually attempting it. The back day had ridiculous exercises like the 'corn on the cob' pull up. Or maybe that was the original? Either way, it is intense- let me know what you think of it. The whole no rest push yourself till you bleed from every orifice idea is something I do weekly, but only once a week, not 5 times.
