For starters, there is a bit of false advertising. It says it's 30 minutes, 15 on each body part. Actually, it is only 21 minutes. Perhaps when this was on ExerciseTV it accounted for commercials or something. I don't know because I never watched the channel, I just did the workouts on-demand.
Despite this, it's a pretty good workout. I was sweating from the get go, and my heart rate was up the entire time. The first part involves a lot of squats, and the second part involves a variety of ab moves. I have a feeling I will be sore tomorrow from this workout.
