A selfie captures two adult females inside a gym in Mexico City, Mexico. In the foreground, a female with dark hair pulled back, wearing a black tank top and dark shorts, stands on a treadmill, extending her right arm towards the camera with a pursed-lip expression. A delicate gold necklace is visible on her neck. A light green tumbler occupies the cup holder on the foreground treadmill's console, which displays app icons on its screen. Behind her, a second female with dark hair, wearing a light blue long-sleeved top and dark leggings, stands on an adjacent treadmill, looking towards the camera, smiling, and flexing her right bicep. Multiple black treadmills with digital displays are arranged in rows, and various weight machines are visible in the background of the artificially lit indoor fitness facility.
