10,000 steps a day – this number has become deeply inscribed in our everyday lives. Why does everyone want to walk 10,000 steps? The often-quoted recommendation to walk 10,000 steps a day does not come from a scientific study – as many think – but from a Japanese advertising campaign in the 1960s. This means that 10,000 steps a day will not hurt you in any case. If you take the aforementioned 10,000 steps a day, you can burn between 300 and 500 calories, depending on intensity and body weight.
