Oh there's more than one of us! I also have a stationary bike under my standing desk. It's a cheap recumbent. It's not amazing in terms of ergonomics, so I use it for about 20-30 mins at a time, a few times a day. I used to walk on a treadmill but I found that my head moved enough that focusing on text could be quite annoying. Also, I'd rather get my steps outside. My head still moves on the bike, but it's much less. Also, this way I can just raise my desk and slide the bike under, whereas with the treadmill I was unplugging and going to another room which was less convenient. I have a TV dinner tray thing with a secondary wireless keyboard and trackball that sits just above my knees so I can work while I pedal. And yes it's great for warming up and staying warm all day!
