Query: Challenging practice

The 60 minute main workout is very challenging, but I was really glad to see that her workouts include a shoulder stand and shoulder stretch. Although I couldn't do the advance versions of these poses, I know that I will be able to work up to them. This is not for beginners and a beginner could be someone that has done yoga for 2 years or less. Even the beginner dvd's are useful for the advanced yogini's so my recommendation is not too move to fast through your yoga journey. I really liked this DVD but it was a bit too advanced for me. I will use it as something to work up to. The morning quickie will be great a couple times a week and the pm workout twice a week. I do have other yoga workouts that I will use when I feel like I just can't do this one.
