Query: Pilates Workout?

This video says its a 40 minute workout? After all the talking and needless posturing by the instructor the workout ends up being about 20 mintues or so. Then when you actually get to the workout the time in between the demos and actual workouts is very disruptive. You can master this video is 2-3 sessions. When you spend [MONEY] for a workout video this is NOT how you want to spend your money.
