Trying out one of the ana/ravi DVD's by chance, I now own all of them(in the space of 7months!). I used to look out for exercise videos that are short, preferable 30 minutes or less (In fact this one has sets starting at 15 minutes which is one reason I first chose it) But I happily do the Fat Free Yoga in entirety because I can feel and see the difference, I feel so good, so well, so renewed and inspired! Thank you Ana & Ravi! Because of your yoga, and your inspiring words, I have lost weight, awakened myself and feel so much more hope and strength. I so appreciate the thoughts you put into your DVD's, the instructions are crystal clear- I can almost be sure of the posture and movements even if I have my eyes close; I do not feel nagged at, I feel encouraged and supported, and I love the music! I have tried other DVD's and felt disappointed in them all. Ana & Ravis DVD's are the only way I get a whole, complete, energetic workout. I feel complete, and my spiritual self is awakened. It is very relaxing but you still get a great workout!
