I ordered this product because it came as a set with Barry's Bootcamp Belly Blaster workout and Toning Power Cords. I was interested in the 1000 Calorie Workout because I wanted a hardcore workout that would burn mega calories. The two instructions features in this workout dvd is: Barry and Cindy Whitmarsh. Barry does a lot of loud yelling that can be very annoying. Cindy Whitmarsh on the other hand does not yell but it very motivating and she help keep track of the countdown to the next workout. There are background fitness people showing different variations of the workout moves to fit your needs. If you don't have the Toning Power Cord you can use hand weights or a stretch band. Each workout consist of 100 reps to be completed. In this particular workout the transformer is used during certain workouts. I do not own the transformer so I skipped over those workouts. Overall I found the workout to be very boring. I did not care for Barry's constant loud screaming and yelling.
