My treadmill has been sitting quietly for some time now, all alone in the corner of my kids' playroom, completely neglected and collecting quite a blanket of dust. I noticed the dust yesterday, just more than four weeks after our last run together, and I felt sorry for it. No, I felt sorry for me. It's been 30 days since my tummy tuck surgery, and the spotting the dust on my trusty treadmill symbolized just how inactive I've been. Doctors orders, I know. But I simply had to clean that thing off and take it for a spin.

My spin wasn't too much -- just a walk, at 4.5 miles per hour, with no incline. I managed quite easily for two miles, all the while dreaming ahead two weeks when my doctor gives me the OK to start running again. How great it will be.

Is your treadmill -- or elliptical, or stationary bike, or whatever it is you're ignoring in the corner of your house -- collecting dust? If so, give it a quick wipe-down, hop on, and take that thing for a whirl. It'll do you a world of good. It did me.
