Gritty fitness portrait by old-school boxing ring AI Image Prompt

A gritty, realistic fitness lifestyle portrait of {argument name="subject" default="a male athlete"} leaning back against the ropes of an old-school boxing ring inside a worn vintage gym. Mid-length vertical composition, framed from about mid-thigh to slightly above the head, with the subject centered and facing the camera. He wears an oversized heather-grey pullover hoodie with the hood up, visible drawstrings hanging down, soft cotton texture, natural folds, and a front kangaroo pocket; black satin-like athletic boxing shorts with white trim and curved white piping near the hem; and white hand wraps on both hands, slightly frayed and loosely wound. His posture is relaxed but strong: both arms draped outward and resting on the ring ropes at left and right, shoulders open, torso square to camera, hands hanging naturally over the ropes. Hair is dark brown, short-to-medium length, slightly messy and visible under the hood at the forehead. The physique is natural and athletic with realistic proportions and understated muscle definition. The boxing ring shows exactly 3 visible rope colors: a red rope in the upper background, a pale grey-white rope crossing behind the hands and waist, and a dark blue rope across the lower foreground. Background is softly blurred with distressed beige walls, scattered vintage gym posters and banners, industrial wear, and dim training-space atmosphere. Lighting is soft natural indoor light mixed with ambient gym light, creating gentle shadows and a moody cinematic tone. Photorealistic texture, subdued earthy colors, shallow depth of field, high detail in fabric, wraps, skin, and ring ropes, editorial sports portrait style.
