Query: Disappointing

Much too slow and too short. I'm not yet at the intermediate level of pilates and I still found this too easy. While it was hard for me to do some of the positions, at the end I wasn't even tired nor did my body feel like it had been worked out. I found the simpler 10 Minute Workout more satisfying even though it was at a lower level. Very disappointing.
