I bought this book in December 1999, right after having a cervical disketomy where they replaced two ruptured discs in my neck with a bone graft from my hip. I told myself, that as soon as I felt up to working out, I would start this program.Three weeks after my surgery, I started working out and eating better using the guidelines in the Body for Life book. After two weeks on the program, I have lost 8 lbs. and am feeling great!Now, mind you... I have to work out with a neck brace on and have had to work around my injury as not to damage the work that the doctor did in December. But to date, I have had no problems... So, if I can do it, even with a neck brace on, then anyone can do it. I recommend this book for ANYONE, even persons with disabilities or obstacles to overcome!This book has the guidelines for anyone to successfully start a healthier lifestyle.
