Detailed explanation-1: -Examples of antagonistic pairs are: ⚫ Biceps and triceps-at the elbow joint. As the biceps bends or flexes the elbow joint by contracting, the triceps relaxes. As the arm straightens, the opposite occurs.
Detailed explanation-2: -For example, the biceps muscle, in the front of the upper arm, is a flexor, and the triceps, at the back of the upper arm, is an extensor. When you bend at your elbow, the biceps contracts. Then the biceps relaxes and the triceps contracts to straighten the elbow.
Detailed explanation-3: -When you do a triceps extension, the roles are reversed-your biceps are the antagonists and your triceps are the agonists.
Detailed explanation-4: -During elbow extension, triceps is agonist muscle and biceps is antagonist muscle.
