When extending an arm into a straight position, the triceps is considered the agonist muscle and the biceps is the antagonist, since the triceps muscle generates the motion to straighten the arm and the biceps contracts to return the arm to the original position.
The biceps muscle is in the front of your upper arm. It helps you bend your elbow and rotate your arm. It also helps keep your shoulder stable. Tendons attach muscles to bones. Your biceps tendons attach the biceps muscle to bones in the shoulder and in the elbow. If you tear the biceps tendon at the shoulder, you may lose some strength in your arm and be unable to forcefully turn your arm from palm down to palm up.
