P90x
I tried doing it pre op and it kicked my ass. Couldn't get through a work out. Also, the whole macho thing kinda irked me, but I'm an aerobics girl, the male jokes were a little old to me. Like he does moves like "The Heisman". Its just very very male oriented. If you can deal with that and are up for a challenge, go for it. Its just not for me.
