Very encouraging, Might M! Love the story about your mom and how exercise makes stairs not painful for her. And about the carbs building muscle! My muscles disappeared while on paleo–flat rear, 1000-pound legs, etc., even though I only weighed about 125 (low for me). Those chair squats are a good idea, too. Wish I could do the PT, but I don’t have insurance right now. On the knee exercise DVD comments, I read that several folks thought the info there was the same as they’d paid thousands for through PT, so I think I definitely need one for direction. I appreciate that y’all care. When pain is present, it’s hard to push past it in order to not have pain, but I know it is time to do so.
