身材勻稱的運動系女子穿黑色比基尼跪在健身房地板上

A full-body photograph of a fit, athletic young woman with long wavy brown hair, looking directly at the camera with a subtle expression. She is wearing a minimalist, cut-out black strappy bikini top and matching skimpy black bikini bottoms, seated in a kneeling pose on the rubberized floor of a gym. The background features modern gym equipment, including weight racks, benches, and mirrored walls under bright indoor overhead lighting, captured with a sharp focus and photorealistic detail.
