Three individuals are bent over, perhaps stretching or bowing

Three individuals are bent over, perhaps stretching or bowing. One wears a gray shirt, another a red shirt, and the third a black shirt with blue and white striped pants. They appear to be on a concrete surface with white lines, possibly a court. A backpack lies on the ground, along with a pair of black shoes. The scene suggests a physical activity or exercise taking place outdoors. Part of a person wearing jeans is visible in the upper left corner.
