I came across this article in a magazine in a doctor's office, and then I found it online. It's written by a PT who works with patients with chronic illness. This article is directed toward people with FM and CFS, and I thought his advice was stellar. He has some great recommendations on how to get started, how much is enough, and how much is too much. He also encourages that even small steps are steps in the right direction.
