In a brightly lit, indoor martial arts training area, a person in black shorts and shirt practices catching a small yellow ball while barefoot on a large grey mat. Another person in black and patterned pants walks along the back of the mat. A third person in blue shorts and shirt practices running and catching the ball as well. Cylindrical black pads are spaced around the room. There are flags on one wall and framed images on another. The person filming moves their index finger into the frame.
