Final answer:
A grip where the palms face each other is called a neutral grip, which is used in various exercises like hammer curls. In a neutral grip, palms are neither pronated nor supinated, but instead, face each other directly. The correct answer is options C.
Step-by-step explanation:
Supination and pronation are movements of the forearm that describe the orientation of the palm. Supination refers to the movement that turns the palm to face anteriorly (as in the anatomical position) or upward, while pronation refers to the motion that turns the palm to face posteriorly or downward. When the palms are facing each other, they are not in a fully supinated or pronated position, making c) Neutral grip the correct answer.
