Dear Dr. McGill,
Thank you for your input on inversion. Your methods have helped me enormously, after growing up following bodybuilding pinciples which have caused me a lot of over use injuries and a current auto accident. After going to therapy I discovered your research and have both of your books. Your “big three” are part of my daily life and have helped enormously. In addition to their functional benefits, they really toughen up your core. I have been continually practicing and learning your methods. I only wish I would have discovered you many years ago. Thanks again for your help.
