Full-body vertical shot of a muscular man with light-medium skin and short dark hair under a white cap taking a mirror selfie. He stands facing the camera in a wide stance against a wooden door, wearing a white ribbed tank top covering his torso completely, black tight-fitting shorts ending mid-thigh revealing thick quadriceps and calves, grey knee-high socks worn barefoot. His right hand holds a smartphone at chest level while his left hand rests behind his back holding the waistband of his shorts. Soft indoor ambient light highlights defined pectorals and deltoids; clean background with minimal distractions captures confident strength in gym photography., a single uninterrupted photograph only, no written words or typography anywhere in frame, no captions, no app UI, no social-media post layout, no screenshot borders
