I'm sure this has been asked before but I had no luck with a search. I've owned Body Max for a year now and have never gotten around to doing it. It looks rather daunting, but I've pretty much mastered most of Cathe's choreo and I just did IMAX twice without much difficulty. I was wondering how tough this workout really is. My biggest problem is finding the time for a long workout, but I may schedule it on a challenge day. I know a lot of people like to break this vid up into 2 parts. Does anyone do it from beginning to end?
