Query: Wish I had not bought this.

I guess studio time must be very expensive, cause Denise Austin rushes through the exercises like the set is on fire. Maybe if she had cut down the intro, there would have been more time for exercising.It seems a little disjointed with the constant change from floor to standing exercises. Before you can get to the floor, the exercisers are on rep 2 or 3. Then it's back up again.There's a lot of talking going on, with exhortions to "sqeeze, sqeeze, sqeeze!" Perky is an understatement.
