In January, I stopped sitting at my desk and converted it to standing. I wrote about it here on my blog:
I’ve gone one step further, and put a treadmill under the desk. NOW I am WALKING while working. The treadmill is set to 1 mile per hour. I never break a sweat, and can feel my brain working better, since my circulation is better. If I spend 8 hours at the desk, that’s 8 miles walked…I lost 5 pounds in a week!
