Book excerpt: The first of a three part series. Most abdominal books or magazines show pictures of exercises that are meant for the advanced or people who do not suffer from lower back pain. But, I have taken a different approach. I picture the body as a house; there are certain steps to take to ensure that a house stays strong and sturdy for many years.
