Focused Gym Training Portrait

Create an ultra-realistic vertical gym portrait of a young South Asian man seated on a black padded strength-training machine. He is wearing a black sleeveless Adidas-style athletic tank top with a pink logo and navy blue track pants with three white side stripes. He sits upright with one hand firmly gripping the machine handle, looking slightly to the side with a calm, serious, focused expression. Preserve realistic masculine facial proportions, natural skin texture, subtle beard and moustache, thick dark layered hair, detailed eyes, natural lips, and authentic facial features. Show realistic arm definition and natural body proportions without excessive muscular enhancement. The background should be a modern gym with exercise machines, mirrors, weight equipment, metal frames, black leather padding, and a green artificial-turf area. Use shallow depth of field with the subject sharply focused and the background naturally blurred. Soft indoor gym lighting, realistic shadows, natural skin tones, detailed fabric and leather textures, DSLR photography, 4K resolution, photorealistic quality, crisp facial details, realistic anatomy, natural colors, and no artificial or AI-generated appearance. Maintain the original composition, pose, clothing, camera perspective, and overall atmosphere. 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.
