A young woman is captured in a mirror selfie within a gym identified as Obsidian, located in Munggu, Indonesia. She stands in the mid-ground, holding a grey smartphone in her right hand to take the photo, with her left arm resting on a barbell equipped with a black padded shoulder protector. She has light brown hair, a neutral expression, and is wearing a black sports bra with a "New Balance" logo band, black leggings, yellow wired earphones, and a black lanyard. Tattoos are visible on her left arm. The barbell on her left is loaded with multiple black weight plates, each marked "OBSIDIAN" and "50 kg". The background, visible in the mirror's reflection, depicts an active gym environment. Various red-framed strength training machines and cardio equipment are present. Several other individuals are visible: a man on a cardio machine and another standing further left, two women in athletic wear standing together near equipment in the mid-right, and a man further right. Large windows along the gym's back wall reveal green foliage outdoors. The gym features a dark ceiling with rectangular LED light fixtures and a dark grey floor, with a section of light wood flooring visible on the left, also marked "OBSIDIAN".
