I've been doing upper body exercises, that I can do sitting in a chair. I've also been doing exercises I was doing in PT. Lynne, I cannot get down on the floor. Not right now with my knee. Even if I got down there, I wouldn't be able to get back up. (help...i've fallen and cant' get up). I'm moving, and thats what counts. After surgery and my healing is in progress, I will be able to do more and more. Sandy
