A woman with long brown hair is exercising in a room that appears to be a workout studio or changing area. She is wearing a black sports bra, gray cargo pants, and white socks. Her stomach is visible, and there is a tattoo on her left side. The woman is positioned on a large gray exercise ball, with her hands on the ball and her legs extended behind her. She is lifting one arm straight out to the side, performing an exercise that likely engages her core and upper body. The room has a gray floor, a light-colored ceiling with visible pipes and fixtures, and a row of dressing rooms or changing areas behind her, distinguished by gray curtains and wooden-framed mirrors. Three round light fixtures hang from the ceiling above. The lighting in the room is bright.
