Donna in forma con leggings rosa in posa in una palestra moderna

A young female fitness model with fair skin and a toned physique, dark hair in a high ponytail with loose wavy strands framing her face. She wears a white Nike sports bra and bright pink high-waisted leggings with a white side stripe, visible Nike logos. Her skin has a subtle sweaty sheen highlighting muscle definition, with a small script tattoo on her left collarbone. Neutral expression, direct eye contact. Shot in a modern high-end gym, leaning one hand on a black weight bench. Treadmills and floor-to-ceiling windows behind her with a blurred city skyline. Medium shot, eye-level, shallow depth of field, strong bokeh. Bright soft commercial fitness lighting with natural window light and soft directional fill. High-end retouched, ultra-realistic, premium fitness photography style.
