In an attempt to capitalise on the popularity of the 1964 Tokyo Olympics, a Japanese health science professor invented a pedometer, named Manpo-Kei, which translates as 10,000-step meter. But there was no actual research behind the 10,000 number other than it sounded good. That number has stuck ever since.
So do you really need to walk 10,000 steps a day in order to stay fit? The short answer is no. According to experts, you can get similar health-boosting results from hitting around 8,000 steps a day instead, because the benefits start to plateau after that. While walking is great for your health, research suggests 6,000 to 8,000 steps might be a better goal, and anything more than 8,000 doesn’t actually count in terms of health benefits.
