Why the 10,000-step myth started—and why science disagrees

The popular 10,000-step daily target was never based on science. Instead, it began as a clever marketing trick tied to the 1964 Tokyo Olympics. Over time, this number became widely accepted as a health guideline—despite lacking strong evidence. In 1964, a Japanese company launched the Manpo-kei, the world’s first pedometer. The name translated to '10,000-step meter,' a nod to the Olympics that year. The device’s branding pushed the idea that walking 10,000 steps would keep people fit.

Recent studies now show that 7,500 steps a day is sufficient for good health. Beyond this number, extra benefits start to fade. For older adults, an even lower range—between 6,000 and 8,000 steps—proves safer and more effective. Speed and effort also matter. A brisk walk delivers far more health benefits than a slow, casual stroll. Simply hitting a step count isn’t enough—how you move plays a key role.

The 10,000-step rule remains popular, but research suggests it’s unnecessary for most people. A daily total of 7,500 steps—or fewer for older adults—can provide the same advantages. The focus should shift from step counts alone to the quality and intensity of movement.
