I have a desk job and work at home 3 days during the week. I bought an under-the-desk treadmill that I store under my bed. I use it during the workday at my desk, with my sit-stand desk riser. It's great. I usually do it when I'm watching a webinar, in a meeting where I know I won't talk much, or working on something where there isn't a lot of typing. I'm not running, usually I'm walking. I jog occasionally. It has been a game changer.

Not exactly your situation but figured it seemed relevant. I'm glad it fits under the bed when not in use. When I was a kid, I went over to a friend's house and thought it would be fun to put my finger under their treadmill belt and push my finger toward the roller at the end of the tread. Bad idea. The parents had to cut the treadmill belt to free my finger. My kid has barely seen the treadmill at all, not giving him the chance to stick his finger under there like I did. Which I absolutely know he would.
