Fast walking is the exercise between walking and race walking. A study shows that fast walking has become the most popular exercise in China and many people walk more than 5,000 steps a day. The results of the study are from QQ users. About 37% of the people choose fast walking as their favorite exercise; over 23% choose running and more than 14% choose riding bikes.

Fast walking and running are easy, cost little and work well, so they are popular. And many people would rather do exercise in nature than go to gyms(健身房). It’s best to walk fast for at least 10 minutes at one time and walk up to 6,000 steps every day.
