Phyllis, there's a big crew of BFL alumni in the
Weight and Resistance Training forum and I know they be happy to answer any questions for you or tell you about their experiences. I see that there's a BFL thread there right now that you might want to check out too.
Bill Phillips' brother Shawn just came out with
Strength for Life, which is supposed to expand and complement BFL. I haven't read it yet but it's received good reviews.
Good luck! BFL is a wonderful program that's gotten some amazing results.
