I have been doing yoga for about a year and this video has become one of my favorites. I started off with an AM/PM DVD with Rodney Yee and enjoyed it but did not feel very challenged. I moved to a Power Yoga DVD by Rodney Yee and found it very challenging. I did that for about 6 months and then needed something different. Bryan Kest instructs more during the video then Rodney. He walks you through all of the posses and makes you really feel part of his class. Rodney goes through the posses with out any type of conversation. If you need encouragement during your workout then this Power Yoga would be a great choice. The DVD has three workouts each one harder then the next.
