Have you seen those new computer treadmill combos they are starting to put in offices?
I saw it on GMA I think a few weeks ago. It's a slow moving treadmill fitted up to a desk with a computer and phone on it. So while you're doing computer work, talking on the phone, etc. you're walking the whole time instead of sitting. They did a scientific study on this and everyone in that experimental office lost pounds as in quite a few for all of them. They were all hooked.
One lady improvised for this at home and took out the middle section of her kitchen table and laid it across the treadmill in the front and hooked her computer up so that it sat on the table insert and she walked away while answering her email and such.
Got me to thinking.
