For years, 10,000 steps a day has been the magic number on every fitness tracker. But that goal was never based on solid science. A major review of data from more than 160,000 adults has found where the real benefits of walking begin to level off, and for many people, it is a much more reachable number.
In short
- The 10,000-step target originated in a Japanese promotional campaign, not in a scientific study, as NPR reported.
- A review led by Melody Ding of the University of Sydney, published in The Lancet Public Health, analyzed data from more than 160,000 adults.
- Around 7,000 steps a day, the benefits start to level off, though more steps are never a bad thing.
Where 10,000 steps came from
The famous figure did not come from a laboratory. According to NPR, it originated in a Japanese promotional campaign and stuck around for decades, simply because it was round and easy to remember.
What the research found
Researchers led by Melody Ding, a public health professor at the University of Sydney, pooled data from more than 160,000 adults around the world. Compared with people who took only 2,000 steps a day, those who reached about 7,000 steps had a nearly 50% lower risk of dying during the study period. Even going from 2,000 to 4,000 steps was linked to a risk nearly 36% lower.
“7,000 steps tends to be the range where there seems to be diminishing return on investment for increasing more steps,” Ding told NPR. In other words, the biggest gains come from moving from very little to a moderate amount.
Other benefits linked to walking more
At higher step counts, the review also found lower risks of type 2 diabetes, cardiovascular disease, depressive symptoms and dementia. The researchers noted that some of these results are preliminary, because they rest on a smaller number of studies.
Age makes a difference
Amanda Paluch, a researcher at the University of Massachusetts Amherst, has found that the benefits plateau earlier for older adults: around 6,000 to 8,000 steps a day for people in their 60s and older, compared with 8,000 to 10,000 for younger adults.
And speed matters less than you might think. “We actually don’t see an association once we consider the total number of steps,” Paluch said, according to NPR.
Should you stop at 7,000?
Not if you already walk more. Ding says people who already reach 10,000 steps or more have no reason to cut back. And as William Kraus of Duke University put it: “Anything is better than nothing, more is better than less.”
How to reach your number
- Start from where you are, and add steps gradually rather than aiming for a big number overnight.
- Split your walking across the day: a short walk after meals adds up quickly.
- Pair walking with simple strength moves, like this wall exercise for upper-body strength.
- Choose gentle, regular movement, the approach Jane Fonda now swears by.
The studies show associations between steps and health, not proof that steps alone cause these benefits. Still, the message is encouraging: you don’t need 10,000 steps to feel the difference. Every walk counts.
