Hate reading? Watch the video! (More info here, though.)
This is my treadmill desk! As of this writing, I have been using this for five months. This is not a new idea (I’ve wanted to do this ever since I saw this video five years ago), but I haven’t seen anyone use these particular parts. If you’re interested in “building” one, this page will give you Amazon links, prices, and advice (though I’m certainly no expert). Prices are what I paid on Amazon; they may have changed since then. Links will open in new tabs.
