P90X Ab Ripper X Help?

Which Ab Ripper X do you do?
In the schedule it says Ab Ripper X Days 1,3,5
do you do the Disc (disc 12) or the Ab Ripper X that plays after the work out?
when do you actually do the disc?

You will do ab ripper X after every strength workout: ie days 1,3,5. The disc 12 is just provided so that you can do the ab ripper at a later time if you desire. They are the same workout.
