While running today on the treadmill, my knee popped and my workout came to a screeching halt. Not sure what the problem might be but I'm going to take it easy for a few days, in hopes that it is nothing major. Taking it easy is not something that I have experience with because I tend to have an all or nothing attitude about working out. I purchased a knee brace and have been icing it. Could be interesting moving around my classroom and school tomorrow. Maybe my fourth and fifth graders will take pity on me and be angels. Nah! Fat chance of that one.
