Why walking helps developers
Long debugging sessions and code reviews benefit from low-grade movement. Walking at 1.5–2 mph keeps blood flowing without pulling attention from logic-heavy work. Many developers report that walking helps them think through architecture problems they'd otherwise stare at.
When to stop walking
Pair programming over video, live demos, and high-precision mouse work suffer. If you spend half the day screen-sharing, plan to stop walking for those blocks rather than fighting the bounce.
What matters most for developers
Deck stability during typing is non-negotiable. A narrow or wobbly belt makes bracket-heavy code miserable. Noise also matters — mic pickup during standups is a real concern. And since developers tend toward long unbroken sessions, the treadmill needs to handle 60–90 minutes without overheating or feeling punishing.
