There are first impressions reviews (viewed the workouts but haven't tried them yet) up on the Video Fitness forum. From their comments:
Low Impact Circuit looks much better than the clip - but has some freeze issues during the triceps (two people mention this). No torquey movements, easier choregraphy than Low Max, but with a good fun factor. High rep, low weight muscle work.
The review of Butts and Gutts is interesting - supposedly the TOUGHEST lower body workout ever. Pace of Leaner legs, Killer hams/quads workout, killer stability ball section. And the floor work with ankle weights will make sure you don't walk.
I'm stoked...
