A group of about 10 children are performing exercises on a yellow and black martial arts mat in a well-lit room. The children are lying on their stomachs and lifting their legs in the air. Most of them are wearing athletic clothing or martial arts uniforms. The room has a brick wall on one side and a window on the other. The ceiling is black with bright lights. There is a red stripe near the ceiling on the wall near the window. The overall impression is of a martial arts class or sports practice for young children.
