Hey HN,

I wrote an article about the negative effects of sedentary work, how I wanted to reduce them, and the solution I ended up building.

The idea is not to scare you into doing something by quoting scary research numbers, but to increase awareness of the dangers that desk work is exposing us to, and to hopefully inspire people to take their health more seriously. I'd also love to discuss what works and what doesn't work for people who are already trying.

For transparency:

- The article mentions Limberly, an app I am building. It's not publically available yet, but I'll happily invite you to be a tester if you get on the waitlist.

- I'm not a native English speaker (writer), so I used Claude and LanguageTool as an editor/proofreader. The actual content, research, and thinking is done by me.

- Limberly is built with Flutter and is NOT vibecoded. I do use Claude Code for being faster at building widgets and quickly testing things out, but I am strict about building the core myself. I want to always understand the codebase so I can maintain and develop the app.

This is my first HN submission, so if I've broken any rules, sorry; I'll happily edit or resubmit an updated post if required.
