Took my kids to see a movie called Nim's Island a while back. Not entirely memorable, but there is one scene that sometimes crosses my mind. It's the one with Jodie Foster working away on her laptop while walking on a treadmill. Now that takes coordination, I remember thinking while sitting all cozy in my theater chair. There is just no way I could ever do that.

Walking while working may not be that far off, and it seems the practice could really pay off. Researchers in one study developed a workstation with a treadmill so employees could exercise while working. Obese volunteers took this scenario for a ride and walked for one hour at one mile per hour while typing a document. They burned 191 calories. Those who did the same work seated at a desk burned 72.

Not a bad idea, this treadmill office set-up -- if you can manage it. I just don't think I can. How about you?
