Gym Mirror Selfie Pose

Please strictly follow the uploaded reference images, preserving the person's face, proportions, skin texture, and hairstyle 100% accurately, without any alterations, beautifications, or reinterpretations. Ultra-realistic gym mirror/selfie style images showing the same woman in a modern gym, three-quarters of her back view. She is dynamically posing, lifting one leg high behind her, performing natural flexible stretches or playful kicks, then turning to look at her right shoulder with a confident smile. One hand casually holds a black fingerless weightlifting glove, with a relaxed and athletic posture that emphasizes a fit and well-proportioned physique, without exaggeration. She wore a black slim-fit long-sleeve cropped top with a thumb hole and a small white heart logo on the sleeves, high-waisted gray seamless sports shorts, a small white tracksuit logo in the center of the back belt, and white sneakers with black accents. Her hair was tied into a high ponytail, with a few loose strands, and her skin was natural with highlights. The environment is a clean, modern gym with rubber floors, dim, cool fluorescent lights overhead, and faint red jump boxes, black sandbags, and fitness equipment in the background. The lighting is moody and authentic, creating soft shadows and subtle highlights on skin and fabric. Authentic smartphone candid fitness photography, with clear subject focus, natural movement, and high-detail textures. Negative tips: facial or hair changes, frontal view, extra limbs, distortion, beauty filters, plastic skin, cartoon/anime, blur, text, watermarks, extra characters, messy focus.
