The video shows a woman in a gym, wearing a black tracksuit, throwing a volleyball. She is standing in front of a group of people who are sitting on the floor. The gym has a wooden floor and a large window with white blinds. The woman has her hair tied up in a bun and is holding the volleyball with both hands. She throws the ball with a smooth motion, and the ball flies through the air. The people sitting on the floor are watching her, and one of them is wearing a black shirt with the number 12 on it.
