Turn the attached photo into a realistic post-workout mirror selfie in a gym locker room. Keep the person exactly as shown in the photo, including her face, facial features, skin tone, hair, body type and natural appearance, without retouching that changes who she is. If no photo is attached, use the Person described below.
Show her standing in front of a large locker room mirror, holding a smartphone at chest height with one arm while the other arm rests naturally by her side. Place the Gym Bag on the bench or floor beside her, clearly visible but secondary to the subject. Dress her in the Workout Outfit. Include lockers, a bench, hooks and subtle signs of a real gym environment in the background. Use harsh overhead fluorescent lighting with direct highlights, firm shadows and slightly uneven exposure, preserving the candid feel of a phone selfie. Keep realistic skin texture, natural posture and believable mirror reflections. Frame the image in the Format, with no added text, warped anatomy or artificial beauty retouching.
Use these details:
Person: "woman in her mid-20s with a natural, athletic appearance"
Workout Outfit: "black sports bra, charcoal leggings and white training shoes"
Gym Bag: "black duffel bag with a small gray towel beside it"
