The shoulder muscle that is considered the strongest supinator is the biceps brachii.
The biceps brachii is the strongest supinator of the body. It is a powerful muscle located in the upper arm that helps to rotate the forearm into a palm-up position.
The muscle that is considered the strongest jaw muscle is called the masseter muscle.
The biceps brachii muscle is primarily responsible for elbow flexion. It crosses both the shoulder and elbow joints and is a strong supinator of the forearm.
The biceps brachii muscle acts as a synergist for supination of the hand. It works in coordination with other muscles, such as the supinator muscle, to rotate the forearm and bring the palm facing upwards.
The antagonist for the supinator muscle is the pronator teres muscle. These muscles work in opposition to each other to produce rotation of the forearm.

The masseter muscle in the jaw is often considered the strongest muscle in the body based on its ability to generate powerful biting force.
The masseter muscle in the jaw is often considered the strongest muscle in the human body based on its force of bite.
supinator muscle hold your arm like u r holding a bowl of soup, hand facing up. pronators pour out the soup, hand facing down.
This is mostly achieved by the Pronator Teres and hte Pronator Qudratus muscles.
