What is "power walking"

vb. (present participle of power walk English)

n. a form of cardiopulmonary exercise consisting of rapid walking accompanied by vigorous swinging of the arms

Power walking or speed walking is the act of walking with a speed at the upper end of the natural range for the walking gait, typically 7 to 9 km/h (4.5 to 5.5 mph). To qualify as power walking as opposed to jogging or running, at least one foot must be in contact with the ground at all times (see walking for a formal definition).
