Josh Waitzkin

Josh Waitzkin is an extremely decorated competitor in Chess, Chinese Push hands (Like Chinese Judo) and BJJ. He is also the author of The Art of Learning. I read this book earlier this year and I believe that it has changed my viewpoint on learning bjj which in turn has helped my performance on the mat. In this vid Josh teaches Tim Ferriss how to execute the Marcelo-tine using his special brand of teaching.
