A man in a gray shirt, black shorts, a black baseball cap, and light blue sneakers is lying on his back on a grassy field. He is performing a core exercise. His legs are bent at the knees and lifted off the ground. He claps his hands together, sometimes over his head and sometimes in front of his knees. Behind him is an orange metal structure with horizontal bars. In the background, there is a fence, trees, a building, and a cloudy sky.
