Which muscle is used to curl the forearm at the elbow?

Explanation:
Curling the forearm at the elbow is elbow flexion. The biceps brachii is the primary muscle that shortens to bend the elbow, bringing the forearm toward the upper arm, and it also helps rotate the forearm (supination) which complements the curling motion. The triceps extends the elbow, opposing the curl. The deltoid works at the shoulder, not the elbow, and the latissimus dorsi moves the arm at the shoulder as well. So the biceps brachii is the muscle best suited for curling the forearm at the elbow.
