Wysportowana kobieta w stroju w panterkę na bieżni

A full-body fitness portrait of a stunning young woman with long, silky [platinum-blonde] wavy hair standing on a treadmill in a bustling modern gym. She turns slightly to look over her shoulder at the camera with a playful, confident smile. She has a lean, athletic physique with a defined back, sculpted waist, and toned legs. She is wearing a [leopard-print sports bra] with thin crisscross back straps and [matching high-cut leopard-print booty shorts], paired with white ankle socks and white sneakers. One hand rests casually on the treadmill handle while the other hangs naturally. The background features rows of cardio equipment, overhead TV screens, motivational wall signage reading "[NO JUDGEMENT ZONE]", and vibrant gym interior lighting. Realistic skin texture, fine hair strands, fabric detail, high-energy fitness aesthetic.
