An authentic smartphone mirror selfie in a gym, vertical 3:4

An authentic smartphone mirror selfie in a gym, vertical 3:4 frame. An adult woman aged 25 or older sits on a narrow bench inside a strength-training frame, her torso slightly turned. One hand rests beside the seat while the other holds a light-colored phone over most of her face; she looks at its screen beneath full bangs. She has naturally imperfect, shoulder-length dark brown hair and wears a slightly glossy black long-sleeved zip-front bodysuit with smoky-gray sheer tights covering her feet. Her legs are crossed, with one extending toward the mirror; the overlapping tights create natural variations in transparency. Surround her with a barbell, weight plates, metal training equipment, a blue drinks vending machine at the back left, a wall poster, and dark speckled rubber flooring. Uneven overhead gym lighting leaves warm reflections on the fabric and legs. Preserve mirror smudges, slightly tilted framing, smartphone wide-angle perspective, and mild image noise, as though she captured a quick moment between exercises.
