muscular forearm 3d model

Generate a full 3D model of a muscular, well-defined human forearm together with the hand. The model must include the entire forearm from the elbow up to the wrist, plus the hand. The palm is facing straight up. The fingers are tightly clenched into a fist, with the thumb resting on top of the index and middle fingers. The forearm should look athletic and toned, with visible muscles and tendons. Do NOT generate only a hand without a forearm. The forearm is required and must be clearly connected to the hand.
