For my August 14 column, I share some information about a professor who re-engineered an office to allow for increased physical activity. As a result, 18 individuals lost a total of 156 pounds. In the column, I provide some advice for re-engineering your own space and work habits, such as using a mobile phone so you can walk while talking and replacing your chair with an exercise ball (thanks for the idea, Emma!). Let me know what you've done to work more fitness into your work.
