You’ve heard it before: walk 10,000 steps a day to lose weight!
But does that actually work? And why specifically 10,000 steps?
Is it sound fitness advice, or is it a marketing tactic designed to sell pedometers and fitness apps?
The answer: It’s kind of both. Let’s talk about it.
Where Did 10,000 Steps Come From?
The 10,000 figure wasn’t born in a research lab or recommended by a panel of doctors. It came from the 1965 marketing campaign of Yamasa Tokei Keiki, a Japanese clock and instrument company.
In the aftermath of the 1964 Tokyo Olympics, the company released the first consumer pedometer. They called it the Manpo-kei, which translates directly to “ten-thousand-step meter.” The company decided on the number 10,000 because it’s a round, memorable figure. Not to mention, the character for 10,000 (万) also carries connotations of abundance and completeness in Japanese culture. Some also note that it vaguely resembles a person walking.
Their timing was perfect. With Japan buzzing with Olympic-fuelled enthusiasm for health and fitness, and walking being arguably the most accessible form of exercise, Yamasa was able to position their device as the everyday person’s ticket to a healthier life.
Walk 10,000 steps a day. Simple. Catchy. Easy to sell.
And the figure simply persisted. The concept spread globally, and decades later, it’s still a shorthand for a healthy lifestyle. Almost every fitness tracker, smartwatch, and health app has it as a default goal.
So, Does the Number Actually Hold Up?
Yes, it’s undeniably a marketing tactic, but it’s still solid fitness advice. However, 10,000 steps a day is not some magic threshold for a measurable health benefit.
Most Americans don’t get 5,000 steps a day, which most doctors consider sedentary. But that doesn’t mean you need to double that and aim for 10,000.
A 2025 meta-analysis found that even just 7,000 steps a day was associated with a 47% lower risk of all-cause mortality compared to low step counts.
Technically speaking, yes, the 10,000 number holds up—but current science tells us it’s an overshoot if anything. Unless you have very specific goals, there’s no reason to fret if you land at “just” 8,712 steps.
Why the 10,000 Myth Persists
Why is the 10,000-step figure still popular? A few reasons.
First, it’s a brilliant round number. Memorable, psychologically satisfying, and easy to communicate. The “7,500 steps challenge” just doesn’t have the same ring to it. Additionally, 10,000 steps, also being a five-digit number, carries a weight to it—it feels like a real challenge, not just a casual stroll.
Second, the fitness industry has a vested interest in keeping it alive. Pedometers, apps, and smartwatches have all built their campaigns and notifications around the 10,000-step figure. It’s a multi-billion-dollar industry with a massive data collection footprint. If you value your privacy, use a VPN when syncing information on these apps over public networks.
Third, it’s not terrible advice. With the average American only getting 5,000 steps in, encouraging people to double their movement is not a bad thing at all. Walking 10,000 steps can potentially burn around 300-500 calories (it varies by person), which is right in line with the daily calorie deficit typically recommended for sustainable weight loss.
What You Should Actually Do
The science is clear that 10,000 steps is not necessary for a healthy lifestyle. You can walk 3,000 fewer steps and still reap similar benefits or perform other forms of exercise. After all, walking 10,000 steps means walking between 7 and 8 kilometers, which takes around an hour and a half to two hours. That’s not a realistic daily commitment for every single busy, working adult.
Of course, the extra 3,000 steps (or more) won’t hurt at all. Moving more is never a bad idea, and it can also help you lose weight depending on your diet goals.
However, if you’re just starting out, perhaps the best thing to do is not to focus on a specific number right out of the gate. Not 10,000. Not even 7,000. Instead, simply aim to move more. Track how many steps you’re averaging now, then aim to gradually increase it. If you’re averaging 3,000 steps, aim for 5,000. If you’re at 6,000, try to push toward 7,500.
But, if you prefer to do so or if your goals align with it, there’s no reason not to aim for 10,000.
Beyond Steps
Beyond the step count itself, the quality of movement matters too. Nordic walking, brisk walking, and varied terrain all engage more muscles and elevate your heart rate more than a slow stroll. Not to mention, resistance training also offers other critical health benefits that cardiovascular training doesn’t.
At the end of the day, fitness has never been purely a numbers game.
