A large number of exercise apps have a target of 10,000 steps per day, such as the default fitness tracker on Galaxy Watches and so forth. This equates to perhaps 1.5–2 hours of walking for most people, depending on pace.
However, official exercise recommendations are often lower: for instance, the US Department of Health recommends 150–300 minutes of moderate exercise per week, which is under 45 minutes per day on the high end; similarly, the Mexican government recommends 30–60 minutes of moderate exercise per day.
As such, where does the common fitness app recommendation of 10,000 steps come from? Is it based on specific research?
