ภาพพอร์ตเทรตหญิงสาวเกาหลีสายสปอร์ตในฟิตเนส

A professional photograph of a [20-year-old athletic Korean woman] with a toned, feminine physique. She has a high ponytail and wears a crownless tennis visor headband clipped to her forehead. She is wearing a fitted black cropped t-shirt ending at the navel and modern breathable black athletic tights with perforated panels. Standing in a slight S-curve pose with her head tilted slightly forward, she pulls the hem of her shirt slightly upward with one fingertip to reveal defined abs, while her other arm is held slightly away from her body with a clenched fist, flexed with subtle vascularity. Set inside a gym with a softly blurred background. Dramatic cinematic lighting, with realistic skin texture and a light sheen of sweat.
