Query: Great Controlled Power

I am enjoying this DVD. It is great Power Yoga without quick movements. Instead you move into each pose and really get into each pose and what it is doing. Although it is not quick, you still feel the workout and power of the pose. I have taken some of the quicker moving power yoga courses, but had found them too fast moving when I started and really like the slower controlled power on this DVD.It has helped improve my yoga practice, including being able to work into some of the faster power yoga practices I previouosly could not do, and if you are looking for something that is powerful but not quick, this is a good option. The instructor's really provides great guidance and I am now working through the Intermediate section, which is a very good workout so far.
