In a well-lit indoor gymnasium with a yellow and blue mat, a bald man in a white judo uniform with a black belt demonstrates a martial arts move. He is barefoot and facing the camera, with his right leg raised high and his arms extended for balance. Several young people in similar judo uniforms, some with yellow or green belts, stand observing him. The background includes hanging exercise ropes, a wall-mounted poster depicting martial arts stances, and a fenced-off area. The ceiling features a complex network of steel beams and fluorescent lighting fixtures.
