A beautiful young american woman with fair skin, long straight brown hair with bangs and a few loose strands framing her face, in a modern gym. She is doing a side stretch pose: both arms raised high above her head, hands clasped together, elbows extended, torso slightly twisted and leaning to the side, hips angled, looking directly at the camera with a confident and slightly seductive expression, full lips, sharp eyeliner.
She is wearing a loose-fitting cream-colored ribbed tank top that drapes over her body with deep side cutout, showing subtle cleavage and underboob shadow, and matching cream-colored tight athletic shorts. Toned athletic body, visible abs, defined arms and legs, glowing skin with light sweat.
Background: bright modern gym with large mirrors reflecting her back in the same pose, black cable crossover machine on the right, white ceiling with recessed lights, air conditioning unit visible. Professional studio photography, cinematic lighting, soft highlights, sharp focus, 8k photorealistic, highly detailed, realistic skin texture, natural colors.
