Common collocations

Cultural note

The 10,000 steps per day guideline actually originated in Japan in the 1960s with the marketing of a pedometer called 万歩計(まんぽけい) (literally 'ten-thousand-step meter'). The name itself helped popularize the 10,000-step goal worldwide. Today, 歩数計(ほすうけい) is the more technically precise term, but 万歩計(まんぽけい) remains far more commonly used in everyday speech.
