Ultra-Realistic Gym Fitness Portrait

Create an ultra-realistic 8K HD fitness portrait of a handsome young adult man with a completely different, original face, thick textured black hair, a neatly trimmed beard, expressive eyes, and a muscular athletic physique. He is sitting on a gym workout bench, leaning forward with his elbows resting on his thighs and his hands loosely clasped over a weight plate. He wears a fitted black sleeveless gym tank top, black athletic joggers, blue-and-white high-top sneakers, black wrist wraps with subtle green details, and white wired earphones. Add a small realistic tattoo on his upper arm and natural sweat on his skin. His expression is confident and focused as he looks slightly to the side. The background features a modern professional gym with weight plates, workout equipment, textured dark walls, rubber flooring, and soft window light. Use cinematic directional lighting, realistic skin pores, detailed muscle definition, natural body proportions, sharp facial details, realistic fabric textures, professional DSLR photography, a 50mm lens, shallow depth of field, balanced contrast, and premium editorial color grading. Keep the entire seated pose, both arms, hands, legs, and sneakers naturally proportioned and visible. Square 1:1 composition, photorealistic quality, ultra-detailed 8K-style finish, no collage, no duplicate person, no extra fingers, no distorted anatomy, no cartoon effects, and no watermark.
