This video is, as others have said, for those with some yoga experience, but beginners who persevere will benefit as well. The scenery and the music is very relaxing and helps you to focus on your postures. If you follow at your own pace, you will slowly progress and be thrilled as you become more flexible, more relaxed and more energized. I have several yoga tapes, this is my favorite. It is long (almost 1 hour) but I see that as a positive. We all need to slow down and this is a healthy and challenging way to do that.
