The video shows two men in a gym demonstrating a self-defense technique. One man is wearing a black shirt and the other is wearing a gray shirt. The man in the black shirt is holding the man in the gray shirt in a headlock, and then he uses his hand to push the man's head down and break the hold. The man in the gray shirt is then released and steps back. The man in the black shirt then walks away. The gym has a black floor and white walls, and there are various pieces of gym equipment in the background.
