Two young boys in judo uniforms are practicing on a yellow mat in a judo studio. The first boy, wearing a plain white belt, performs a throw, flipping the second boy, who has a green belt, onto the mat. The boy who was thrown briefly gets up onto his hands and knees. Then both boys stand, bow, and engage in a grappling hold. The studio is well-lit, with a black ceiling and gray walls. There is a climbing ladder against one wall.
