The scene shows a woman standing in front of a large mirror in the free-weights area of a gym. She wears a black long-sleeved zipped jumpsuit and light-colored sneakers. Her hair is pulled back into a loose bun, and her makeup is polished and flawless. She holds a water bottle in one hand and a smartphone in the other, with a workout app visible on the phone screen. The mirror reflection reveals gym details including a power rack and a rack of dumbbells. Natural daylight streams in from large gym windows, creating a clean, authentic look.
