Hi, I just read about your evening of sports. I don't think this is the way to go about starting doing exercise. It is a little too violent for someone who has not been physically active. If not done properly, sports could kill you. So, take it easy, one step at a time. This is your MOTHER speaking.
You know, even on crutches, I know what's good for you.
Please take care of yourself.
bye, love Mom
