I love my treadmill desk
I've been using it for two years now and have gone through several different setups before finally arriving at something that really works well for me. If you haven't read James Levine's (Mayo Clinic) "Move a Little, Lose a Lot" book you absolutely must to understand why treadmill desks work and aerobic devices like under-the-desk cycling pedals don't do the same thing. The key is *not* to go aerobic but to raise your basal metabolic rate. I've experienced fantastic weight loss and reduction in diabetes/glucose ever since integrating the treadmill desk into my daily routing - typically under 3 hrs a day realistically given meetings and certain tasks like precision graphics work that I still need to do sitting down. The treadmill desk has changed my life and several of my colleagues got one, too, after trying mine out when I was out of town. We all swear by it.
