Fit woman posing by weight machine in sunlit gym

An beautiful young athletic woman in a gym wearing a white cropped sports bra and high-waisted white leggings stands beside a green-framed weight machine. Shot from roughly mid-thigh to above the head, she angles her torso slightly, one hand on her hip and the other resting on the machine, showcasing a toned core and obliques. Natural window light pours in from large grid windows, casting warm golden highlights and soft shadows across her physique and the equipment. The background includes a bench, weight plates, and gym apparatus, with shallow depth of field to keep focus on her silhouette. Textures: glossy stretch fabric, white fabric, metallic greens, chrome accents, and wood-toned floor. Color palette: black, emerald green, warm amber, cream walls, and steel greys. Style: photorealistic, cinematic lighting, high detail, strong anatomical accuracy.
