My knees, my knees, my knees

Boy did I ever have a wake up call last class.  My knees were not letting me do things I used to do.  I felt like I was back after surgery.  I really need to work on getting my legs back into shape so that they support my knees. So that is my current goal. I still can't do too many pushups because I still have chronic bursitis by the shoulder blade. I have to start going to massage and see if that will work it out.
