What Is a Spondylitis Exercise Program?

My doctor told me to join one of the ankylosing spondylitis support groups to receive a poster showing the exercises I needed to do to help prevent my condition from getting worse.  Do you have any information regarding this?

This information regarding the poster of exercises is available from the Ankylosing Spondylitis Association (http://www.spondylitis.org/). It is, indeed, a very helpful poster.
