The video shows a gymnasium where several children are practicing acrobatic moves on a yellow mat. The children, ranging in age from approximately 5 to 8 years old, are either shirtless or wearing blue or white judo pants. One child is wearing a full blue judo uniform. They are running, kneeling, and performing tumbles and flips on the mat. The gymnasium has a black ceiling with fluorescent lights, and a brick wall along one side. A red and white stripe is visible near the ceiling on the wall opposite the brick wall. The mat is surrounded by a black border. A large window is visible on the right side of the frame.
