Query: Exercises that can be done by anyone

I suffer from fybromialgia (Chronic Fatigue Syndrome) , it makes it very difficult to exercise because of the level of pain I experience every day. The exercises in the book can be done while sitting in bed. It is still early for the results, but I hope they will help me with time to improve my strenght and flexibility.
