@lioness Are you on Facebook? If so try Silver Sneakers. They have a number of chair exercise routines. I will keep my eye open for other ones too, I am always looking for different exercises and sometimes come across ones that are designed to be done sitting. I have even seen a chair yoga one.
For those of you who might like to take advantage of things like that on Facebook but do not want to have it as a social setting, you can set it up so no one can see that you are on there, or set it up so only a few chosen people can know you are. There are some worthwhile things there, such as the Silver Sneakers exercises.
