Take a look PERHAPS at my earlier post featuring Jessica Walden
Most sensational Kukkutasana B ever? Plus 25 Laws of Self practice for Ashtangi mums AND Ashtanga Yoga, Pregnancy, Birth and Motherhood
and her youtube page
And while we're at it how about the earlier Supta kurmasana tutorials.
UPDATE: New website offered by Lu Duong with interviews containing interviews with Authorised and Certified Ashtanga teachers, it's along the lines of the Guruji book. First interview is with Jessica.
Also, David Keil's book just arrived, review to come in a week or so but how about some interactive blogging, let me know what YOU would particularly like to know about the book, whether in comments or via fb and I'll try and work it in to the review.
