This is a really awesome yoga dvd, I would highly recommend it. The relaxing flow is especially effective, but the energizing flow wasn't exactly what I expected. It will definitely help me, though. The dvd isn't totally user friendly for naive people like me; it took awhile to figure out that to make it play, you have to click not on the word, but the little line that pops up underneath it when you hover over it. Overall, great stretch routine for about any level of ability- Jessica gives you a lot of options as to how far to take it (in difficulty), so almost anyone can benefit. I have only tried the AM and PM flows once each, but I already feel like they could be very helpful in improving posture and decreasing some of my neck and back muscle pain (I have mild scoliosis). P.S. It is totally true... no creepy chanting or spiritual component, just a good stretch. The music in the PM flow has an extremely relaxing effect.
