I have a sore knee today so I decided not to go running. I don't know why it is sore, it is inflamed. Instead I went to the gym and did 35 minutes on the elliptical cross trainer. Then spent 10 minutes lifting weights. I am lucky there is a Gold's gym just across the street from where I work. When I am running in the morning I will go over there for what I call my 10 minute work out to lift some weights.
