The biceps and the triceps.-McKenzie
An Antagonist
The triceps muscles extend (straighten) the arm, while the biceps muscles flex (bend) it at the elbow joint.
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.

When you bend your arms, the muscles in your biceps contract, causing your forearm to move towards your upper arm. This movement occurs at the elbow joint, which allows for the bending motion. Additionally, bending your arms can help you lift, push, or pull objects.
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
