Physical Activity

Got back from the second week of volleyball and I am nowhere near as sore as I was at this point last year. I'm playing better too. Throughout the match, though, I feel as if I'm carrying around a bit of dead weight. I need to drop about 20 pounds and really get back into running shape. What can I do to really motivate myself? I've been trying to start up running again since my senior year in college, and that was 10 years ago. It's the same reason every time. I've gotten lazy and until something can snap that - until I can snap it, I'm going to stay out of shape.
