The Spinal Engine

Great interview with Serge Gracovetsky, author of " The Spinal engine", which, it seems, is out of print. I remember Paul Chek referencing this book in his Scientific Back Training course.This interview is a very unique look at how and why we move and how critical the spine is to the process.Now, if I can find someone to sell me the book.Ebay only wants $200 for a copy!
