It's definitely a cardio workout as well as a toning workout.
When I first used it, I was a bit disappointed because I felt it was much more basic than previous PS workouts. Then I got into it, and considered the first 15 minutes or so as technique practice (the intensity builds more slowly than in the other workouts).
The camera work is pretty odd at times: the camera operator seems obsessed with Ilaria's armpit sweat and with Patricia's face!
-I think it's odd they chose to do THIS one on DVD, since they may be using its sales as an indication of whether or not other DVD's would do well.
