Fitness & Wellness — Side-by-Side Results
Prompt
"A candid phone-camera selfie of a woman in her mid-20s with a messy high ponytail and minimal makeup, wearing a cropped hoodie over a matching sports bra and high-waisted leggings, slightly sweaty and smiling while looking near the camera in a gym locker room mirror. She’s holding a shaker bottle and adjusting her earbuds with one hand, towel draped over her shoulder, with realistic fluorescent gym lighting and a slightly cluttered background (lockers, benches, water bottle). The vibe feels like a quick post-workout Instagram story, unfiltered and everyday."
