Ultra-realistic documentary phone-snapshot in an ordinary Chinese community gym, vertical about 3:4. A clearly adult, stunning 23-year-old East Asian woman, fashionable, confident and gentle in temperament, leans alone against the treadmill handrail, head down looking at her phone. The photographer stands slightly ahead-left in the aisle, about 35–50mm, capturing her head, thin low-neck bust line, slim waist and hip-thigh curves; the equipment must not block her chest and waist; also keeping a partial view of the neighboring machine, the mirror and wall notices.
She has a well-proportioned full figure: naturally full bust with natural weight and soft rounded contours, obvious bust-waist difference; slender waist, real soft volume in hips and thighs. Not too thin, not flat, no bodybuilder muscles.
One foot steps on the treadmill deck, the other touches the ground, upper body slightly turned toward the aisle. Head lowered at the screen, not looking at the camera. The sideways angle reveals both the fullness of her bust and the waist-hip curve; the thin fabric gently clings with each breath. Expression quiet.
Jet-black long hair in a high ponytail falling to the shoulder blades, wispy bangs sticking to her face. Oval face, fair skin, light makeup: thin brows, natural eyeliner, light blush, moist bean-paste lips. Not smiling.
Top: a mist-pink ultra-light crossover-strap sports camisole, thin straps, deep V opening to the upper edge of the cleavage, narrow lace trim at the neckline. Thin knit fabric, slightly translucent, skin-hugging and supporting the bust's weight, crossover pleats cinched at the waist sides, hem ending just below the ribs leaving the whole midriff exposed. No jacket.
Bottom: light khaki high-waist lightweight sports shorts with a cutout knit band at the side waist, very short hems just covering the hip line; when standing, the hip-thigh curve is wrapped by the thin fabric. Bare legs.
Feet: white lightweight sports shoes with breathable mesh upper, not bulky running shoes. A thin gold chain resting on the collarbone, small gold earrings, thin bracelet.
A mini woven bag hangs on the treadmill cup holder, next to it a half-open bottle of water. On the right, the neighboring machine shows only half the shoulder of a person in a grey T-shirt. On the wall are notices "请擦拭器械 / Wipe equipment" and "请勿占用器械". Cool-white ceiling lights plus daylight from floor-to-ceiling windows, hitting the thin camisole. Phone documentary style, medium depth of field, background clear, no studio look.
