Do you need 10,000 steps a day?
Ten thousand steps is a popular target, but it is not a minimum you must reach for walking to benefit your health. Studies find benefits at lower counts, most of all when people increase from very little activity. A phone or watch can help you track that increase, alongside the separate goals for aerobic exercise and strength.
Where did the 10,000-step target come from?
Most accounts trace the target to a Japanese pedometer marketed in the 1960s as the manpo-kei, meaning a ten-thousand-step meter. It was a memorable product goal.
No clinical trial produced the figure. It was a target that sounded right, and it was round. The pedometer sold well, walking clubs in Japan adopted the number, and it spread from there. In the 2000s, almost every wearable device shipped with the figure as its default daily goal, and every smartphone later did the same.
Ten thousand steps may suit someone who enjoys walking and can manage that amount. For another person, a lower starting target may be more practical. The increase in suitable activity is what counts, and you do not need to reach a universal number.
What have step-count studies found?
Since wearable step counters became common, researchers have been able to follow large groups of people, record their daily steps, and see how their health turned out years later. Researchers have now published several such studies, and they show a consistent shape.
- Very low counts carry the highest risk. People who take only a few thousand steps a day have the highest rates of early death and heart disease in these studies.
- The benefit curve is steepest at the start. Going from 3,000 to 5,000 steps a day produces a larger improvement than going from 8,000 to 10,000.
- The point of diminishing returns varies. A 2022 pooled analysis found the mortality association levelled off around 6,000 to 8,000 steps for adults aged 60 or over and around 8,000 to 10,000 for younger adults. These are observational findings and do not amount to personal prescriptions.
- Pace matters less than count. Several studies found that the total number of steps predicted outcomes better than walking speed did, though brisk walking has its own benefits for fitness.
One much-cited study followed older women in the United States and found that the risk of death fell as steps rose, and levelled off at around 7,500 steps a day. A later pooled analysis of many studies confirmed the general shape across age groups. The precise number at which the curve bends varies between studies and populations, so 7,000 to 8,000 is a working range rather than a fixed line.
More walking can be useful well below 10,000 steps. There is no single count that captures all the benefits of walking or applies to everyone. Age, health, pace, other activity and the outcome studied all affect the interpretation.
How accurate is your step counter?
A phone step counter uses an accelerometer, a small sensor that detects the rhythm of walking. It is accurate enough when the phone is in a pocket or a bag that moves with the body. It records nothing when the phone is on a desk, in a locker or charging on the kitchen counter.
A watch or band on the wrist counts more of the day, because you keep it on. It also counts some arm movements as steps, such as brushing teeth or chopping vegetables, and it can miss steps when the hands are still, such as when pushing a trolley or a pram.
Using the same device in the same way makes comparisons more useful, although measurement error can still change. Look at several days together, and remember that carrying the phone for more of the day can increase recorded steps without increasing actual walking.
Time-based measures are the alternative. The WHO guideline sets a target of 150 minutes of moderate activity a week, and a brisk walk at about 100 steps a minute over 30 minutes comes to around 3,000 steps. With that conversion, you can read a step count against a minutes target.
Finding walking time in Singapore
The pattern of a Singapore day shapes the count. A walk to the MRT, a transfer at an interchange, a walk to the office, a hawker-centre lunch and the return trip can reach 4,000 to 6,000 steps for someone who does not drive. A person who drives from an HDB carpark to an office carpark can finish the day below 2,000.
The heat pushes walking into the early morning and the evening. Park connectors, the void deck loop and the air-conditioned links between malls in town are the practical places for the extra steps. You may find the shortfall easiest to make up after dinner, when a 20-minute walk around the estate adds around 2,000 steps at a comfortable pace.
HPB's National Steps Challenge has used a step tracker and reward tiers for several seasons, and it has made step counting familiar to a large number of Singaporeans. HPB sets the reward tiers and changes them from season to season, so check them in the current Healthy 365 app.
Choosing a realistic step target
Start by using the step counter to establish a baseline. Track a week of ordinary days, carrying the phone as usual, to see your typical count. From there, a modest increase, such as 1,000 to 2,000 steps a day, is a realistic first goal.
Keep these points in mind.
- Regular opportunities to walk help make activity sustainable. A busy or low-step day does not erase the activity you did earlier; look at your usual pattern and build from there.
- A short day is still a day of walking. A day of 5,000 steps includes a fair amount of movement, and stopping short of a round number does not undo it.
- Sitting time is a separate matter. You can reach 8,000 steps in a morning and then sit still for nine hours. Breaking up sitting is a different habit, and we cover it on its own page.
- Include strength work too. Walking works the legs and can improve function, but in most cases ordinary walking does not provide enough resistance for all the major muscle groups.
A target should reflect your baseline, abilities and health. Counts below 10,000 can still represent useful activity, and the appropriate goal can change as fitness or circumstances change.
Using your count to build a habit
Ten thousand steps is a useful optional goal, and it is not a medical pass mark. Studies support increasing activity from a low starting point and show benefits below that count. Choose a target that fits your abilities and can grow in small steps, rather than treating a device default as a requirement.
Anyone with a joint problem, a heart condition or a recent operation should ask their doctor how much walking is sensible and how quickly to increase it. Anyone who feels chest discomfort, unusual breathlessness or dizziness when walking should see a doctor before adding more.
A practical next step
Track a normal week, then choose a manageable increase. More walking can help below 10,000 steps. Keep brisk activity, strength exercises and breaks from sitting in your plan too.
