ab ripper x complete

For anyone brave enough to do the ab ripper -it's from the P90X series and is more involved than the rest of this month's challenge but really does some major core work!  I did do a 5 minute ab work out on day 4 but that was just from a workout app I found and it certainly made me realize it has been a while since I've done any sit ups of any kind.  Shame on me! ;)
