I never thought Billy could pick up the ante... This is it..those bands add an aspect that really makes this the ultimate... I have been doing this for 6weeks now and the difference it has made is amazing..... it works, but not without sheer effort, and loads of sweat...I am a huge Taebo fan and have loads of the collections.. I also own this whole set.. The cardio is not that well put together, but alternate the ultimate with basic and the abs, and you are working.... strength, stamina, endurance, I have them all. If you like Billy, and love Taebo, then you will LURVEEEEEEEEEEE these!
