Why do we swing our arms when we walk? Ask Steven Collins, a biomechanical engineer at Delft University in The Netherlands.

Walking Workout


In his experiment, he observed the walk of volunteers, exercising on a treadmill. He found that people who held their arms still during workout spent 12% more energy, and those who moved arms in synchrony with the legs wasted a staggering 26% more. According to scientists, on the one hand, we now know that swinging arms is energy efficient, on the other hand, fitness instructors may focus on exercises with “tied” arms for people who’s seeking to lose weight.
