I recently did this video and must say although it was tough, I felt some of her other videos (like Bodymax) were tougher. I was expecting a harder workout. I think this was because some of the 'intervals' (there are 10), were tough for me to do, not because I'm not advanced enough, they were just uncomfortable. I did, however, like the setup of the video. Before each interval, you did a little step routine, so you won't get bored. I do recommend this video to mix things up, but it's not my favorite. My grade: B+
