Interesting. I went through a marathon training program that used a similar approach to help people who hadn’t been runners (like myself) build endurance. We would run for 5 minutes, walk for 1 minute (or 4/2 or whatever interval is best for your condition).

They make “interval timer” stopwatches that allow you to set multiple intervals (e.g. countdown from 5 minutes, then countdown from 1 minute, repeat).

I actually looked for a Windows desktop equivalent of that “interval timer” stopwatch, because (like you) I thought that would be an effective way to “build endurance” in my work habits.

Would love to hear from anyone who knows of a desktop equivalent of an “interval timer” stopwatch.
