My great friend Karla, who is currently an exercise physiology grad student at UNC, has started a blog called Stay Moving, and it really inspires you to do just that. Move. Get some fresh air. Lay off the macaroni and cheese. I don't know anybody who, during these dreary winter months, couldn't use some encouragement in the whole physical fitness realm. I certainly do. So check out her blog if you know what's good for you. You won't regret it. And who knows, you may be up for running a marathon in a few months. Or at the very least up for running down the street a few blocks or so.
