I like that Sherwin Nicholson book explains about how to self treat back pain both easily and safely, with illustrations and pictures of real people doing the exercises with explanations. I'm a read and see kind of gal! I can remember doing some of these actually in physical therapy pre and post the lumbar surgery. From the excerpt about his book, "Learn how to self treat chronic low back pain easily and safely with this fully illustrated, instructional, low impact, pain-safe, exercise guide long term. The majority of cases of chronic low back pain are either related to, or worsened by specific muscle
weaknesses and imbalances. This specifically designed guide carefully teaches the correct method to move, train and strengthen your body to properly relieve back pain. It uses nonsurgical, non medicinal, and safe methods for all ages and all difficulties. It will help with your current pain, to prevent the return of pain, and to reduce your dependency on medication and surgery. "
It has different sections in his book on limited mobility exercises, progressive exercises, challenging exercises, and maintenance exercises. I like this book very much and have found it to be quite helpful and informative, and a great helper with my lumbar pain issues. I suggest that you stop by his site for more information: Low Back Pain Program I have a picture on Instagram of my calf stretch!
