Bryan Kest's Spinal Strengthening-Live Bootleg This CD is a well-rounded, flowing, hatha yoga class, with the flow directed toward the spine and its circumference of support. This routine comes from nearly 10 years of working intimately with back problems. Even if you do not have a back problem, you will love this unique and invigorating routine. Bryan himself, along with Anya, are photographed in over 100 asanas in the accompanying booklet. Run Time: Approx. 90 Minutes, 8 Tracks.
