I don't want to review the entire video. I just want to add my opinion about the hi/lo portion. Although I think a lot of the moves are "fun," these teach segments really slowed down my heart rate, and as the others said, a lot of time is spent teaching moves that just look cool, and don't do much for my heart rate. Also, there is a lot of high impact which bothered my knees a lot.
