Oooh, I wish I've read your post earlier. I've already bought a couple of books and neither of them is the "7 steps". The books I got are: "The Back Doctor" by Dr. Hamilton Hall, and "Healthy Back Bible" by Dr. Stephen Reed and Penny Kendall-Reed. Oh well.
I didn't know that strengthening abdominal muscles help with back problems. Guess I should do more situps.
Which Toyota car chair did Dr. McKenzie design? I drive a Corolla.
