The same man as in the reference sheet (same face, hair, body, black shorts with a lime waistband, blue running shoes), photorealistic. Strict side view, he holds a perfect forearm plank on a gym floor: forearms flat on the floor, elbows under the shoulders, body in one straight line from head to heels, hips level, glutes and thighs tight, head neutral. Subtle red highlight on the abdominal and glute muscles. Bright modern gym with a blurred background, soft even light. The whole body from head to both shoes is fully inside the frame with clear empty margin on all sides, nothing cropped. No text.
