In September 2008 I had a lumbar lamentomy fusion. I just had another x-ray and the prognosis from the surgeon seems promising. I am grossly out of shape and need to start getting back in shape. I still experience sensation such as pain when I turn when sleeping and I want to get my abdominal muscles back in tone. I am 55 years old and in realtive good health. Aside from walking is the a start program to rebuilding by stomache?
