Query: Great Workout!

I just tried the workout and it was great! I love being able to take a real yoga class in the comfort of my own home. I dont always have time to schedule a class so this DVD is perfect for me. The workout was challenging and easy to follow. The explanation of the poses was easy to follow. This is definately not a DVD that will collect dust in my closet.
