A young male, appearing to be in his late teens or early twenties, is observed taking a mirror selfie in a gym. He is positioned centrally, wearing a long-sleeved gray shirt, navy blue athletic shorts featuring the word "ARMOUR" in white (seen reversed as "ЯUOMRA"), and black athletic shoes with white soles. His hair is short, dark, and wavy, and a black earbud is visible in his left ear. The individual holds a dark-colored smartphone in his right hand, directing his gaze downward toward the screen, while simultaneously using his left hand to lift his shirt, exposing his abdomen, which displays defined musculature. The gym environment features a dark rubber mat floor and prominent floor-to-ceiling glass windows in the background. Reflections of interior lighting, including horizontal fluorescent fixtures, and indistinct external structures are visible in the windows. Structural elements such as white diagonal support beams and gray vertical pillars are visible. Gym equipment includes several weight benches with black padding, one featuring red adjustment levers, and various barbells and weight plates. A large black weight plate rests on a silver barbell in the lower-left foreground, while additional barbells lie on the floor to the right, adjacent to a weight rack holding a loaded barbell. Other gym machinery is partially visible in the background and reflections. The specific location within the city of Plovdiv, Bulgaria, cannot be determined from the provided visual information.
