I’ve used a treadmill under my standing desk for the last 8 years
I’ve used a treadmill under my standing desk for the last 8 years. I love it, and I believe it’s a competitive advantage.
Here’s why:
1. 10k steps a day is generally recommended for good health. I easily hit that goal by walking 2 mph for part of the day while I’m working.
2. Walking reduces my stress and improves my mood.
3. If I sit too long I get restless and groggy. When I walk, I feel more alert.
4. Studies show it aids memory retention and creativity.
5. I’m in my 40s and weigh the same as I did in school. I think the treadmill played a role.
6. “I’m too busy to exercise” isn’t an excuse anymore. I walk and work.

People often ask “Isn’t it hard to walk and type?”
I’ve found it’s quite natural after a few hours if you’re already good at typing.
But I recommend using an ergonomic keyboard since it feels more natural while walking.
I use the Microsoft Sculpt.

Some have claimed the 10k step number is "made up".
This 2020 study found taking 8,000 to 12,000 steps a day was linked to lower risk of dying of any cause during the study, compared with 4,000 steps a day.
