This video is part of a series demonstrating the second part of the warm up: dynamic stretching.
Starting in a standing position, hinge forward at the waist by pushing the butt backward. Return to the standing position, and take a half step backward with one foot. Hinge forward again at the waist. Return to the standing position, and take a half step backward with the other foot. Repeat this motion for about 10 meters to warm up your lower back and hamstrings.
