P90X Series: Ab Ripper X
Tony HortonYear Released: 2004
Categories: Abs/Core
11 exercises. 25 reps.
These are killer. If you want a super-duper-unbelieveably tough ab workout, this is it.
The last exercise has 40 reps (I think even 50, for bonus.) It is really really challenging, and I really feel it (i.e. it hurts to laugh the next day, which for me, means I'm hurting)

Tony is Tony!
