Grit & Focus — Cinematic Gym Portrait

Use the uploaded reference photo as the identity reference for the person's face and physique. Preserve their facial features, skin tone, and natural muscular build. Create an ultra-realistic 8K UHD photograph, 1:1 square composition, of the same person standing shirtless in a dark, gritty gym. Defined chest, abs, and shoulder muscles visible under low-key spotlight lighting. Hands resting low near the waistband of black gym shorts, calm intense expression, gaze slightly downward as if catching breath mid-workout. Background: blurred boxing gloves, a punching bag, and a motivational poster softly out of focus. Warm dramatic spotlight from one side, deep shadow falloff, authentic gym-photography grain, natural skin texture with visible pores, no plastic skin, no CGI look. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
