HomeFitnessCode Walking Pad Treadmill Under Desk, 6.2MPH Ultra Quiet Treadmill <35dB, 2.5HP Running Machine for Office & Home, LCD Display, 300 Lb Capacity, Black-Q2, Black+Quiet

I (62F) have one I bought several years ago from Amazon. Before I retired, I worked remotely from home and would walk on it while attending conference calls and meetings, or during mid-day breaks; I wasn't coordinated enough to use my computer while walking, however. 🤣 I still use it in the winter when snow and cold make it hard to get out of the house to exercise. Edited to add - It's no longer available but was around $200. I wanted the simplest and quietest available at that time, no stand/arm support bar, no incline. https://a.co/d/09HB8nCR
