Description: When you use the resistance chute to exercise, the resistance of the air will produce an backward drag force, so the faster you run, the greater the drag force. Through this exercise, can improve the ability of the user's acceleration, muscle endurance, and enhance the ability to adjust the direction of the high-speed running.
