A judo class, primarily of young boys, is taking place in an indoor gym. The gym is equipped with yellow and black mats covering the floor. Several of the boys are wearing judo uniforms, in varying colors. Other boys are wearing blue athletic pants and are shirtless. In the background, there's an exposed brick wall that has a red and white stripe near the ceiling. Some boys are performing gymnastics-like movements, such as handstands, cartwheels, and rolls. An instructor, wearing blue pants and a black t-shirt, is walking around.
