health π 10k steps goal: Myth or reality?
The popular 10,000 steps daily target actually originated from a 1965 Japanese pedometer ad, not scientific research. This target was set by Yamasa Tokei Keiki for their Manpo-kei device, timed around the 1964 Olympics. Modern trackers inherited this number, which is now the default across fitness apps globally. Phone step counts are estimates based on accelerometer data, not literal foot strikes, and accuracy varies widely. The iPhone's pedometer showed up to an 85% error rate during jogging tests against dedicated systems. πΆ
