How many steps a day do you really need?

Where 10,000 came from

In 1965, a Japanese company sold a pedometer called manpo-kei, which means "10,000-step meter". Japan was in a fitness boom after the 1964 Tokyo Olympics, and the name was round and easy to remember.

It was never the result of a study. That does not make it a bad target. It means nobody had measured it.

What the studies found

In 2019, researchers at Harvard followed about 16,700 women with an average age of 72, who wore a step-counting device for a week and were then followed for around four years. Women who averaged about 4,400 steps a day had a lower death rate than those who averaged about 2,700. The benefit grew with more steps and levelled off at around 7,500.

In 2022, a combined analysis of 15 studies and about 47,000 adults found the same shape. For people aged 60 and over, the risk kept falling until roughly 6,000 to 8,000 steps a day. For younger adults, until roughly 8,000 to 10,000.

Two things are worth keeping in mind. These studies observed people; they show that more steps go together with living longer, not that steps alone are the cause. And they measured how long people lived, not weight or fitness.

What that means for your goal

The biggest difference in both studies is at the low end: going from very few steps to a few thousand more. So the useful goal is not a fixed number. It is a little more than what you do now.

A simple way to start: look at your average over the last few weeks — the Health app on your iPhone shows it — and set a goal slightly above it, one you can reach on most days. A goal you hit four days out of five keeps you walking. One you miss every day stops meaning anything.

If you have a health condition, the number your doctor gives you is worth more than any study average.

Counting without thinking about it

Your iPhone already counts your steps whenever it is in your pocket or bag, and the Health app shows the daily total for free. What a step counter adds is everything around the number: a goal you can see on the Lock Screen, a streak, a nudge when you are close in the evening, and a record of the walks themselves.
