PUB/PLB??
The only Combo Bonus I can think of, and it may not even be listed as such on the DVD, is on the Pyramid Upper & Lower Body dvd. I just looked at the Workout manager, and it's not listed as a premix of either dvd. From what I can remember, it's a pyramid up of both routines without the ab section, and lasts approximately an hour. HTH!!
