I preordered the step & sculpt one, and just got Basic step from the Ya Yas. I did the 30-minute step w/o from Basic Step and really enjoyed it! I have to admit that I love the other music from Cathe's w/os better (i.e. Buttercup & Tainted Love immediately come to mind), but this w/o felt perfect for my 5-month pregnant body!
I think my only regret on the presale was NOT ordering Muscle Max but oh well, it's not as if I don't have enough OTHER w/os! LOL
