Authentic Japanese shonen sports-anime illustration, the exact same character as in the reference sheet (short spiky dark-brown hair, shirtless, black shorts without waistband, bright blue sneakers). Strict side view, full body in frame with space above the head and below the feet. He stands ready to start a burpee: knees bent, torso leaning forward, arms swinging down, intense focused eyes, dynamic action pose. Bold line art, sharp dynamic cel shading, light speed lines, subtle red glow on working thigh muscles. Bright clean white modern gym background in anime style with soft blur. No text, no watermark.
