Final answer:
An uppercut is a punch that uses the biceps brachii muscle to power the fist from a low starting point to finish straight up in front of the face. The correct option is (1).uppercut.
Step-by-step explanation:
The biceps powered punch that begins with the fist low and ends up with the fist straight up in front of the face is called an uppercut. This punch utilizes the biceps brachii, which is a two-headed muscle that crosses the shoulder and elbow joints to flex the forearm while also assisting in supinating it and flexing the arm at the shoulder.
The biceps brachii, along with the brachialis and brachioradialis, work together to flex the forearm. When performing an uppercut, you typically pivot your hips and shoulders, utilizing these muscles to generate power from a lower position to an upward trajectory towards the target, which is usually an opponent's chin or body.
