Fitness & Wellness — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy brown hair in a black sports bra and high-waisted gray leggings takes a gym mirror selfie right after a workout, slightly flushed with a few loose strands stuck to her forehead, holding her phone up while the other hand adjusts her ponytail, looking near the camera with a casual half-smile. Real commercial gym locker area with slightly messy bench, water bottle and resistance bands in the background, fluorescent overheads mixed with natural window light, candid “post-leg-day check-in” vibe like an Instagram story. Shot on phone camera with minor grain and imperfect framing, authentic and unpolished."
