I've been doing yoga for years, and I just found these routines didn't capture any of the things I like about yoga. The movements are often very complicated and the instructor moves so quickly through them that it is hard to follow. Also, the movements are more akin to fluid dance moves than yoga postures that help in stretching. I understand the concept of vinyasa, but I have found the flow of the breath better captured in other DVDs such as Yoga: Gentle Practice. Also the music played during the routine is loud and distracting. Finally, the instructor talks incessantly during the routines and tends to add a lot of abstract comments meant to capture the spirit of the session, but I found all of this talking distracting as I was trying to keep up with the movements. I am returning it to Amazon for $2: it's not even worth that much to me.
