The sit-stand experiment
Updated 4 September 2026: the rhythm described here has since been corrected. The finding says get up every twenty minutes; it never says for how long. Mosey now stands by for twenty minutes and walks you three to twenty, each walk its own length — fifty-two of them.
On the first of June I had a completely random thought: alternate between sitting and standing, at most twenty-five minutes standing per round. Only during working hours, nine to three. No app, no goal, no streak. The emphasis was on the switching, not on the standing.
I’d done the standing-desk thing a few years earlier, the way everyone did it: stand for most of the day, white-knuckle it, feel virtuous. After three months I was incredibly stiff and my ring said nothing had changed. Not fitness, not weight, not sleep. Nothing.
The experiment was different because there was no pressure behind it. In the first week I managed about three full rotations a day, sit to stand to sit. In weeks two, three and four it stayed about the same. And that was fine. Nobody was counting.
What actually happened
Three things, none of which I expected.
The transitions got cheaper. All day, not just at the desk. Lying flat on the couch in the evening I’d get up for something I would have left until morning. Standing at the counter I’d notice, sooner, that it was time to sit. The experiment had quietly trained away two rules I didn’t know I was following: once you sit, you stay sitting; once you stand, you stay standing.
The flat got cleaner. Once you’re already standing you put the thing away, you move the other thing. Nobody plans that. It’s a side effect of being upright at a moment you’d normally be horizontal.
And by the first of July the question had changed from what if I stood to what if I walked. So I ordered a walking pad.
The lesson Mosey is built on
The magic was the gentle switch, not the duration. Twenty-five minutes was never the point; it was just short enough that stopping never felt like failing. What mattered was that a change of state arrived on its own and I could take it or leave it.
That’s the whole design of the Nudge. The pad starts. Twenty-five minutes later it stops. Twenty-five minutes after that it starts again. Nothing counts your rotations, nothing turns red, nothing remembers whether you skipped yesterday. It nudges transitions; it never enforces streaks.
Streaks punish. Nudges forgive. I got a month of three rotations a day out of a thought with no pressure behind it, and it still worked. That’s the counter-story to every app that thinks guilt is a feature.
