Query: Most Worthless Workout!

This has to be the most worthless workout I've ever done. I'm mad for wasting my precious workout time on this but am glad that I only rented it. I never felt the urge to turn it off more than with this one and I'm a workout DVD addict. The cardio portion is an absolute joke. A few taps and stretches that's it. I think a Leslie Sansone warmup is more challenging. She is barefoot throughout, that should be a clue that there is no cardiovascular challenge. I felt completely unsatisfied after this workout, my heart rate was never elevated and I never broke a sweat.
