prime mover (agonist)
Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
It is known as the prime mover or agonist.
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
Pronation of the forearm and the flexion of the elbow

Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
The Main muscles used when you do elbow curls are the bicep muscles.

In hyper flexion of elbow, I hope you are refering to biceps brachii
Prime mover is the bicep and the antagonist is the tricep.
The Biceps flex the elbow The Triceps extend the elbow
