I've run through the video today (sat on my bum, deciding how much of it I could do!). Anyway, it looks good to me - the steps are straightforward and no massive amounts of jumping up and down (my boobs can't take that!) It's split into 5 sections:
3 dance sections:
cool down/stretch/floor work
At the moment, I think I'll just about manage the warm up, plus just one of the dance sections, then the cool down/stretch/floor work. I like the fact that you can choose how much/little to do and, can swap between the dance sections to stave off boredom.
There's also a free 30 min "tone up" video with it - I haven't looked at that yet.
