Spiegelselfie in der Fitnessstudio-Umkleide

Mirror selfie of a [confident blonde fitness girl in her early 20s] posing in a trendy gym locker room. She has an athletic, toned physique with defined abs, smooth natural skin texture, and blonde hair styled in a sleek high ponytail with soft flyaways. She is wearing a [clean white sleeveless crop top] and [pastel pink GAP joggers], with one hip slightly popped and making a [playful double finger-gun gesture] toward the mirror. A modern smartphone is visible in her hand. Background features geometric rows of [vibrant orange glossy gym lockers] with reflective surfaces. Cinematic interior lighting with soft rim lighting outlining her silhouette, gentle highlights on cheekbones, and shallow depth of field. Realistic smartphone photography aesthetic with natural mirror edge reflections.
