This book is a tome of body science for yoga teachers with over 1000 pages in the second edition. I purchased it a few months ago. While I've skimmed the entire volume, I've spent the most time on the appendix related to balance in yoga postures.
Most yoga instructors can tell you a handful of things that improve balance such as a gazing point, engaged muscles of the standing leg, and mental concentration. Mel Robin has written 80 pages on this subject. He covers gravitational effects on yoga postures; aspects of mechanical metastability; generating counter-torque when falling; balance sensors, and neural repatterning among many, many other topics. This one section alone has changed the way I practice balancing asanas and how I teach them to my students.
With the recent publication of William Broad's controversial book The Science of Yoga: The Risks and the Rewards it's more important than ever for yoga teachers to understand if and how science backs up claims related to the medical benefits of yoga. Robin's book does just that. It looks at the science behind the asanas.
I understand that he is working on his newest edition…
