Selfie frente al espejo en el gimnasio

A realistic mirror selfie in a luxury modern fitness center, capturing two young women posing together from the back to showcase their athletic physique. On the left, a woman resembling [Sydney Sweeney] with blonde hair in a messy high ponytail, wearing an [emerald green] tight-fitting long-sleeve athletic crop top. On the right, a woman resembling [Natalia Dyer] with wavy brunette hair pulled back, wearing a [lemon-yellow] racerback sports bra. Both wear matching [bubblegum pink] high-waisted seamless scrunch leggings and white athletic crew socks. The background features rows of treadmills, weight lifting stations, and industrial exposed ceiling pipes. Cinematic lighting with vibrant neon blue and purple ambient tones, sharp focus on skin texture and fabric details.
