Ten thousand steps a day has become the default goal on fitness trackers and phones. It sounds scientific. It isn’t, really. The number’s origin is murky, but Harvard researchers have pointed out that it may trace back to 1965, when a Japanese company marketed a pedometer called the manpo-kei, which translates roughly to “10,000 steps meter.”
That doesn’t mean step counts are meaningless. Over the past decade, researchers have collected step data from hundreds of thousands of people wearing devices, and the picture that has emerged is more encouraging than the old target suggests. Here’s what the evidence says, and how to use it.
The big picture: 7,000 is a strong target
The most comprehensive look so far is a 2025 systematic review and meta-analysis in The Lancet Public Health, led by researchers at the University of Sydney. They pulled together 57 studies, with 31 included in the pooled analyses covering more than 160,000 adults.
Compared with people taking about 2,000 steps a day, those taking around 7,000 had:
- a 47% lower risk of death from any cause
- a 25% lower risk of cardiovascular disease
- a 38% lower risk of dementia
- a 22% lower risk of depressive symptoms
- a 28% lower risk of falls
- a 14% lower risk of type 2 diabetes
- a 6% lower risk of cancer
For most outcomes, the benefits beyond 7,000 steps were modest, although heart health kept improving at higher counts. As one of the authors, Dr. Katherine Owen, put it in the university’s summary, extra benefits past 7,000 were small for most of what they looked at. The lead researcher, Professor Melody Ding, described the goal as shifting the focus from perfection to progress.
Even a little more helps
One of the most consistent findings in this research is that the biggest gains come at the low end. In the Lancet review, moving from about 2,000 to 4,000 steps a day was already associated with measurable improvements.
An earlier study of older women backs this up. Published in JAMA Internal Medicine in 2019, it followed 16,741 women with an average age of 72 for a little over four years. Women who averaged about 4,400 steps a day had a 41% lower risk of death than those averaging 2,700. The benefit kept rising with more steps until it leveled off at about 7,500.
In other words, if you’re currently fairly inactive, you don’t need to leap to a big number to see a difference. Adding a couple thousand steps is a meaningful start.
Does the right number depend on age?
It may. A 2022 meta-analysis in The Lancet Public Health, led by Amanda Paluch at the University of Massachusetts Amherst, combined 15 international cohorts with nearly 50,000 people. The three most active groups had a 40% to 53% lower risk of death than the least active group, which averaged about 3,500 steps a day.
The researchers also found that the benefit leveled off at different points depending on age:
- Adults 60 and older: around 6,000 to 8,000 steps a day
- Adults under 60: around 8,000 to 10,000 steps a day
So 10,000 isn’t wrong for everyone. It just isn’t a magic threshold, and it isn’t necessary to get most of the benefit.
Does walking speed matter?
Less than you might think, at least for longevity. In the 2022 meta-analysis, total steps mattered more than pace once total volume was accounted for. The 2019 study in older women found the same: among women taking the same number of steps, walking intensity wasn’t associated with risk of death.
That said, brisk walking still counts as moderate-intensity exercise. The CDC recommends that adults get 150 minutes a week of moderate-intensity activity, such as brisk walking, plus muscle-strengthening activity on at least two days a week. A daily walk at a pace that makes you breathe a little harder can help you meet both a step goal and the aerobic guideline.
The catch
Almost all of this research is observational. People who walk more may be healthier to begin with, and not every study could fully account for things like age, frailty or existing illness. The Lancet review’s authors noted that the evidence for some outcomes, including cancer and dementia, comes from a small number of studies and has low certainty. The numbers above are associations, not guarantees, and they apply to groups, not individuals.
Still, the overall pattern has been remarkably consistent across countries and study designs: more daily movement is linked to better health, with the steepest gains for people who are starting from very little.
How to use this in real life
1. Find your baseline
Most phones count steps automatically when you carry them, and so do fitness watches. Look at your average over a typical week rather than a single day. Keep in mind that a phone left on a desk or in a bag won’t record every step, so treat the number as a useful estimate rather than an exact count.
2. Add in small chunks
If you average 3,000 steps, aim for 4,000 to 5,000 first. Once that feels normal, add another thousand. Gradual increases are easier to stick with than a sudden jump, and they give your feet, knees and hips time to adjust.
3. Build walking into things you already do
- Take a short walk after meals.
- Walk during phone calls.
- Park farther away, or get off transit a stop early.
- Take the stairs when it’s practical.
4. Pick a target that fits you
For many adults, 7,000 steps is a realistic and well-supported goal. If you’re under 60 and enjoy walking, going higher has some evidence behind it. If you’re older or managing a health condition, smaller increases still count.
5. Don’t forget strength
Steps don’t cover everything. The CDC’s muscle-strengthening guidance, two days a week, matters too, especially as we age.
Steps or minutes: which should you track?
Step counts are popular because devices measure them automatically, but they aren’t the only way to keep score. If you swim, cycle, use a wheelchair or do strength training, much of your activity won’t show up as steps at all. In that case, tracking minutes of moderate activity against the CDC’s 150-minute weekly guideline may be a better fit.
Many people find it helpful to use both: steps as a daily nudge to keep moving, and minutes as a weekly check on whether they’re getting enough sustained exercise. Pick whichever measure you’ll actually look at.
It also helps to treat your number as a range rather than a pass/fail line. A busy day at a desk and an active weekend will look very different, and the research is based on averages over time, not any single day.
The bottom line
Ten thousand steps is a fine goal if you like it, but it was never a medical cutoff. The research points to a simpler message: if you move very little, any increase helps, and around 7,000 steps a day appears to capture most of the benefit for most adults. If you have a health condition or haven’t been active in a while, check with your doctor about what’s right for you.
