In what appears to be a gym changing room or common area in Amsterdam, Netherlands, a woman with long, light brown hair styled in a half-updo records herself in a mirror using her smartphone. She is wearing a black sleeveless crop top, black cycling shorts, and a belly button piercing. White wireless earphones are visible in her ears, and she has a subtle bracelet on her left wrist. The woman smiles and poses for the camera, shifting her weight slightly and placing a hand on her hip. The background features bright orange walls with rows of orange lockers, some open. Large windows provide natural light. On the orange wall, a white sign with inverted text is visible in the mirror's reflection, reading "TRAINEN MET HANDDOEK IS VERPLICHT" (Training with a towel is mandatory). Another similar sign is visible further down the wall. The floor is light-colored wood laminate, and a dark bench is seen on the left side of the frame.
