In a brightly lit indoor space with a high ceiling, a middle-aged man in a black hoodie is instructing a young woman in black athletic attire with a weightlifting belt and white knee-high socks. The man demonstrates a stance or posture, looking down at his feet. The woman is attentively following the instruction. Another younger person in similar athletic clothing stands to her right, while a fourth person looks on from behind the woman on the left. There are spectators seated nearby, evidenced by the backs of heads and wooden chairs. A tall ladder stands against a brick wall in the background. A window lets in light. The floor is made of light-colored hardwood.
