I just got Core Max today. But I also had to order a new stability ball (mine's in the basement & has been through a rather unpleasant sewage backup--'nuff said) & a 10 lb med ball (the only one I have is 20 lbs & I'm thinking I might need something less for this workout) so I can't do it yet. It makes me crazy to have a new Cathe DVD sitting on my shelf that I can't use. x(
