How many steps a day do you really need? Where 10,000 came from and how many are enough

How many steps a day do you need to walk for it to do you good? Everyone knows the number 10,000 — but it wasn’t scientists who came up with it, it was marketers. We look at where the target came from, what large studies showed, and how to reach your own number without forcing yourself.
You close the app at 6,400 and feel like you’ve lost: once again, you fell short of the “target.” On social media this argument goes round in circles — some call 10,000 steps a myth, others consider it the minimum, and in the summer of 2025 a big review in The Lancet Public Health added fuel to the fire. The uncomfortable truth is that your 6,400 steps may already give you most of the benefit. And fitness’s most famous target was born in an advertising department.
Where did the 10,000 steps a day target come from?
From a pedometer ad. In 1965, a Japanese company released a device called “manpo-kei,” which translates as “10,000-step meter” (Harvard Health).
Harvard Medical School epidemiologist I-Min Lee calls the name a marketing tool outright: the round number sounded good and was easy to remember. No one set out to test it in research. The number then simply migrated into fitness trackers as the default setting — and turned into a “norm” that no one ever set.
How many steps a day do you need to be healthy?
Fewer than people think: for most people, the benchmark is about 7,000 steps, and noticeable benefits start even earlier.
In 2025, scientists at the University of Sydney pooled 57 studies in which participants wore pedometers and trackers. Compared with 2,000 steps a day, 7,000 steps were linked to a 47% lower risk of death, 38% lower risk of dementia and 27% lower risk of type 2 diabetes. Above 7,000, the extra benefit for most measures was modest, and even going from 2,000 to 4,000 steps had a measurable effect.
I-Min Lee’s team had seen a similar picture earlier. Among nearly 17,000 women with an average age of 72, those who walked about 4,400 steps a day had a 41% lower risk of death than those who walked 2,700. The benefit grew up to about 7,500 steps — and then leveled off.
