The ten thousand steps target was invented to sell pedometers.
In 1965, riding the fitness wave that followed the Tokyo Olympics, a Japanese clockmaker called Yamasa brought out a step counter named the manpo-kei — roughly, “ten thousand step meter”. The number was chosen because it was round, memorable and looked good on the packaging, and because the Japanese character for ten thousand happens to resemble a walking figure. There were no studies behind it. It has since been printed on more watch faces than any figure in health, and a great many people who walk eight thousand steps a day now believe they’ve failed.
So it’s worth asking what the number should actually be, and then asking a better question than that one.
What the research broadly says
Ten thousand isn’t wrong, exactly. It’s just arbitrary, and arbitrary in the direction of discouraging.
The consistent finding across the large pooled analyses of recent years is that the benefits start accumulating well below ten thousand, and that the curve flattens rather than climbing forever.
Measurable benefit appears surprisingly early — a 2024 umbrella review put the protective threshold at somewhere around three thousand steps a day, which is to say the gap between almost nothing and a bit of walking is where the steepest part of the curve lives. From there it keeps improving, then bends. The plateau tends to land around six to eight thousand for older adults and eight to ten thousand for younger ones. A 2025 dose-response review in The Lancet Public Health landed on roughly seven thousand as the point where you’ve collected most of what’s available, while noting that more is still better if you’re already active.
Two things follow from a bending curve, and they matter more than any single figure.
The first is that the biggest single improvement available to most people is not the jump from eight thousand to ten thousand. It’s the jump from two thousand to five. If you have a desk job and a car, that’s the move on the table, and it’s a bigger one than any watch will congratulate you for.
The second is that if you’re already walking a decent amount, chasing a bigger number isn’t where your next improvement lives. Strength work is. Ten thousand steps a day does very little for muscle mass or bone density, and those are the things that decide how the next few decades go.
For what it’s worth, the UK guidance doesn’t mention steps at all. The NHS asks adults aged 19 to 64 for at least 150 minutes of moderate intensity activity a week, or 75 minutes of vigorous, plus strengthening activities working all the major muscle groups on at least two days. Brisk walking counts towards the first half. Nothing counts towards the second half except actually lifting something.
Three things worth doing
Take a Baseline Fortnight before you set any target. Most people are wrong about their own step count, usually in the optimistic direction, and a target set from a guess is a target set by accident. Carry whatever you already own — a phone in a pocket counts most of them — and don’t change your behaviour. After two weeks you’ll have a real number, and the honest one is often somewhere around three or four thousand for anyone with a desk job and a car. Now you have somewhere to move from, rather than a figure off a watch face.
The other half of being wrong about your steps is being wrong about what they add up to. Stride length varies with height by a surprising margin, which means two people can walk the same distance and finish several thousand steps apart, and both of them will believe the number on the screen means the same thing. The step calculator converts between the two using your height, so you can see what your own baseline is actually worth in miles before you decide whether it needs moving.
Set a Floor, Not a Target. A target is a number you hit on good days and miss the rest, which converts most of the week into failure. A floor is the number you can hit on a bad day — raining, late finish, nothing in the tank — and it works the way a bill works rather than the way a wish does. Set it low enough to be genuinely embarrassing. Six thousand when your baseline is four. Then treat everything above it as ordinary rather than exceptional. The floor is what keeps the habit alive during the weeks that would otherwise end it, which is the same job the smallest possible session does in the gym.
Stack Steps Onto Things Already Happening. Nobody sustains a daily walk that exists purely as an errand of self-improvement. What survives is walking attached to something with its own reason to exist: parking at the far end, getting off a stop early, the shop instead of the delivery, taking the phone call standing and moving, walking the long way back from the school run. Stacked steps don’t need motivation because they’re not a separate decision. This is also the cheapest way to add a thousand or two without carving out any new time, which most people haven’t got.
Pace, and the bit the counter can’t see
A step count is a volume measure. It knows nothing about intensity, which is the part that does a lot of the work.
Twenty minutes of brisk walking — the pace where your breathing has changed and you could talk but not sing — is doing something quite different from the same number of steps accumulated shuffling around a supermarket. Both count for something. Only one of them is training your heart and lungs.
The practical version: if some portion of your daily steps happens at a pace you can feel, the number matters much less. If all of your steps are slow, the number matters more and still isn’t buying you much fitness.
There’s a test for this over in the Fitness pillar that does the job better than any counter will: the Legs-and-Lungs Test, which asks whether you can feel it in your legs and whether your breathing has changed. Two questions, no device, and it settles in about thirty seconds what a step count cannot tell you at all.
Hills are the free upgrade. Steps and slopes turn an ordinary walk into something that leaves you slightly out of breath at no extra time cost, which is the best deal available to anyone with twenty-five minutes and a decent route.
Where the number stops being useful
Counting works right up until it starts running you.
There’s a version of this where someone walks laps of the kitchen at eleven at night to close a ring, and a version where a missed target reads as a personal failure rather than a Tuesday with a lot on. If the count has started producing that, the count is now costing more than it returns, and turning it off for a fortnight is a reasonable thing to do. The walking can continue perfectly well unmeasured — people managed it for a long time before watches.
And the honest caveat: if you’re recovering from illness, managing a heart or lung condition, dealing with joint pain, or you’ve been told to be careful with exertion, the sensible starting number is the one a GP or physio gives you, not one from an article. Walking is about as safe as exercise gets, which isn’t the same as it being right for every body on any given week.
This is Pillar 04: Mindset
Measure first. Set a floor you’d hit on your worst day. Attach the rest to things you were doing anyway.
This sits in Mindset rather than Fitness for the same reason the walk does, and it isn’t a filing accident. The steps are the easy part. What actually decides whether you keep walking is what the number means to you when you look at it — whether eight thousand reads as a good day or a failed one, and who decided that. Ten thousand isn’t a bad number to land on. It’s just a bad number to be judged against, because it was never yours and it wasn’t derived from anything. A floor of six thousand that holds every day for a year is worth considerably more than a target of ten thousand that holds for three weeks in January.
That is the whole pillar in miniature: not the behaviour, but the story running underneath it. A metric you chose is a tool. A metric you inherited off a watch face in 1965 is a verdict you’ve agreed to be judged by without ever reading the terms.
Walking already does another job in this project — the thinking kind, which has nothing to do with the count. The two go together nicely. One of them is measured and one of them isn’t, and you’d struggle to say which does more.
If you want the rest of the Mindset pillar — the mechanisms for the head that runs everything else, and the same systems-over-willpower thinking applied across all four pillars — you’ll find it at thequietreset.uk.
Not a new life. A new direction — starting with the number you can hit on a bad day.
