How many steps a day do you really need?
Your watch wants ten thousand steps. You get six thousand and feel you fall short, or you get fourteen thousand and wonder whether you have now trained. Where does that number come from, and what does it say about you?
Where ten thousand comes from
The number is older than the step counter on your wrist and younger than you think: 1965. In the run-up to the Tokyo Olympics, a Japanese manufacturer released a pedometer called manpo-kei, literally "ten-thousand-steps meter". Ten thousand sounded good, and the character for ten thousand resembles a walking person. It was a product name, not a research finding.
That the number sits on every watch half a century later says mostly something about how good it sounds. Round is easy to remember and ambitious enough to feel like a goal. Research into what steps do for your health only came decades later, and it came out somewhere else.
What research does show
The large studies of recent years follow tens of thousands of people with a step counter over years and look at who falls ill or dies. A pooling of fifteen of those studies from 2022 shows a clear picture: risk falls sharply from few steps to more steps, and that fall levels off. For people over sixty that levelling off lies around six to eight thousand steps a day, for younger adults around eight to ten thousand.
The most important lesson is not at the top but at the bottom. The biggest gain sits between three and seven thousand steps: from very little to ordinary movement. Whoever is at four thousand and goes to six thousand does more for their health than whoever goes from ten to twelve thousand. Ten thousand is not wrong; it is just not the threshold it seems.
Pace plays a smaller role in this than count. Brisk walking helps a little extra, but the difference between walking and strolling is far smaller in those studies than the difference between moving and sitting.
Steps are not training
A step counter measures movement through the day: to the bus, through the office, a walk around the block. That is valuable, and it is something other than training. Training is a stimulus large enough to make your body adapt: your heart, your lungs, your muscles and tendons. Twelve thousand steps spread over a day do not give that stimulus, however good they are otherwise.
The reverse also holds. Half an hour of running yields a few thousand steps and counts in your step counter like a brisk walk. As a stimulus it is something else entirely. Whoever puts both on one counter sees a number that says something about both and enough about neither.
That is why they belong side by side: a step goal for your daily movement, and a training plan for your stimulus. One does not replace the other. A day with a lot of walking is no reason to skip a session, and a session is no reason to sit for the rest of the day.
What a step is worth differs per person and per watch
A step is not a fixed measure. A tall person with long strides needs fewer of them for a kilometre than a short person: roughly twelve to fifteen hundred steps per kilometre walking, and fewer running. So a kilometre is thirteen hundred steps for one person and fifteen hundred for another, and both are equally far.
Watches count differently too. A counter on your wrist reads arm movements, and it misses steps when you push a pram or carry a shopping bag, and adds some when you gesture busily while seated. The difference between two brands on the same day can be hundreds of steps. So compare yourself mainly with yourself, on the same device.
Your own goal from your own weeks
A fixed goal of ten thousand tells someone at three thousand to triple, and someone at fifteen thousand that they may do less. Neither is good advice. A goal that works sits just above what you do now: high enough to ask something, low enough to reach.
That goal comes from your own days. Take your steps of the past four weeks, look where your ordinary days lie, and put the goal a bit above that, not at double. If you reach that a few weeks in a row, the goal shifts up with you. That way it grows with you instead of telling you from day one that you fall short.
What Trimetra does with this
Your step goal in Trimetra comes from your own days of the past four weeks: the app picks a point above your ordinary days, with a lower and an upper limit, and says what the number rests on. If your days lie below the band, the goal is a starting point to grow towards and it says so; if they lie above it, it is a floor you already reach.
Steps come in through your connection, and which brand delivers them is in the article on what the app reads from your watch. They count as daily movement and stand apart from your load: a session counts in your load, a walk counts in your load and in your steps, and a busy day at the office counts only in your steps.
Frequently asked questions
Are 10,000 steps a day necessary?
No. The number comes from a Japanese product name from 1965. In research the health benefit levels off around seven to nine thousand steps, and the biggest gain sits between three and seven thousand. More is not bad; fewer than ten thousand is not falling short.
How many steps is 5 kilometres?
Walking, roughly six to seven and a half thousand, depending on your stride length; running fewer, because your strides are longer. You see your own ratio by putting a measured distance next to your steps.
Do my running steps count towards my step goal?
Yes, your watch simply counts them. But as a stimulus half an hour of running is something other than the same steps spread over the day; that is why your step goal sits next to your training plan and not inside it.
What if I am far below 7,000?
Then that is where the biggest gain is. From three thousand to five thousand does more for your health than from ten thousand to twelve thousand. Start with a goal just above your ordinary days, and let it grow with you.
Trimetra derives your step goal from your own days of the past four weeks and keeps it next to your training plan, not inside it. That keeps steps what they are: a measure of your day, not of your training.
