A woman exercises on a stair-climbing machine at a gym. She wears a sports bra, leggings, and headphones, and her hair is pulled back in a ponytail. The machine is black, and there are exercise balls attached to the frame above her. Other gym patrons are present in the background, including a man in a red shirt and a woman in gray athletic wear. The gym features industrial-style ceilings with exposed ductwork and fluorescent lighting.
