A young adult male is depicted in a mirror selfie taken within a gymnasium located in Aldoar, Foz do Douro e Nevogilde, Portugal. The subject stands centrally, wearing a dark grey tank top, light grey athletic pants, and off-white sneakers, with black over-ear headphones. He holds a smartphone in his right hand to capture his reflection, while his left arm is flexed, presenting his bicep. The gym features dark grey interlocking rubber floor tiles and light-colored walls and ceiling, equipped with recessed lighting. Various black fitness machines are visible in the background and reflections, including a large cable machine on the left, a weight bench directly behind the subject, and other strength training apparatuses. A 'MATRIX' brand logo is visible in reverse on background equipment. A white towel is draped over a machine to the right of the subject's reflection, and a chrome-colored cable machine attachment lies on the floor in the bottom right foreground. Distant figures are faintly visible in the background, suggesting other individuals are present in the facility.
