I got an under desk treadmill. It's flat -- doesn't have the bar that standard treadmills have. It only goes up to 6km/h; but I typically run it around 2km/h anyway. At this speed I can do most things - email, coding, etc. I do have to stop it during meetings where I'd love to run it the most since walking helps me concentrate. I do stop when I really have to concentrate. I've been averaging about 8km/day on work days and apart from associated weight loss I noticed that my back doesn't hurt anymore, I can engage my core better and I don't fatigue as much. Sitting for prolonged periods (ie driving) is now acutely uncomfortable.
