Fibromyalgia Support Group
You're not alone in your pain. Fibromyalgia is a condition that can be difficult to diagnose and manage. If you're trying to cope with pain throughout your body, sleep problems, general fatigue, or other common fibromyalgia symptoms, you're in the right place. The community is here for you to talk about therapies and share your challenges.

This page has instructions and diagrams for "chair yoga" which anyone of any physical condition can do. I have a lot of problems with yoga because my upper body strength sucks - always has no matter how much I work out - but anyone can do chair yoga. http://www.livingwordsofwisdom.com/chair-yoga.html
If you google "chair yoga" you'll find more sites with more pictures, and also some videos on YouTube - if I think of anything else I'll come back and update but this gives you a few places to start.
