A young woman with reddish-brown hair in a high ponytail is taking a mirror selfie in a gym. She wears a black sleeveless romper and a gold necklace. She holds a light pink smartphone in her right hand and a stack of white papers in her left. She smiles and poses. The background, reflected in the mirror, shows several treadmills, other gym equipment, and a dark ceiling with two hexagonal white lights and a blue LED strip light. A red surface is visible in the bottom foreground.
