Query: A Great Idea, A Disappointing Workout

I eagerly awaiting the arrival of this tape as change of pace from my ususal workouts of strength training, aerobics, and yoga. I was very disappointed as I feel that it provides no challenge whatsoever. If you have never done pilates or yoga and need to work on beginning to balance your core than you may like this tape but if you work out regularly in the above practices, thus having some core strength already, than you will probably be left as unchallenged and bored as I was. If anyone knows of a challenging tape that I could get to utilize this new piece of exercise equipment please let me know, otherwise it will become yet another toy for my 2 kids.
