Hi there. I urge you to look for Matt Furey on the internet as soon as possible. His site contains the information you need to banish your back pain forever. You will probably be best to purchase the "combat conditioning" book advertised, but I will attempt to explain the movement involved to you. It is called 'bridging' and it involves you supporting your entire bodyweight on only your forehead and feet. Stay with me. You of course work up to this. U can start with standing upright and bending your upper body as far back as it will go, then back to upright, then progress to "wall walking" , stand against a wall take three steps heel to toe forward until you are about three feet from the wall, then lean backwards and walk down the wall using your hands. I realise this might sound like a joke to you but I am deadly serious, I know how bad back pain can be and this method cured me and others I have taught it to. But this exercise might end your years of misery.
