Fitness & Wellness — Side-by-Side Results
Prompt
"A woman in her mid-20s with messy dark hair in a high ponytail, light sweat and flushed cheeks, wearing a charcoal sports bra and high-waisted sage leggings, holds her phone up for a gym mirror selfie while glancing near the camera with a half-smile. She’s standing by a cable machine with earbuds in, towel over one shoulder and a shaker bottle in hand, captured like a quick TikTok check-in between sets. Bright overhead gym lighting with a slightly smudged mirror, candid framing, realistic phone-camera look."
