In a brightly lit indoor gym, a martial arts instructor in a black t-shirt and blue pants oversees a class of children in various states of exercise. The children, wearing blue judo pants and some shirtless, are practicing floor exercises on a yellow and black padded mat. Some are doing back bridges, others are rolling, and some are standing or walking around. The instructor walks among them, observing and occasionally gesturing. The gym has white walls on one side, exposed brick on the other, and a dark gray ceiling with visible ducts. There are exercise bars mounted on one wall. The video is shot from a static position, showing the full scene.
