During elbow extension, which muscle acts as the agonist?

Explanation:
During elbow extension, the triceps brachii is the primary muscle that shortens to straighten the forearm. It pulls on the olecranon of the ulna, extending the elbow joint. The biceps brachii would be used to bend the elbow, so it acts as the antagonist during this movement. The latissimus dorsi and deltoid mainly move the shoulder and do not drive elbow extension. So the triceps is the agonist for extending the elbow.
