Which action is the opposite of pronation, turning the palm upwards?

The action that is the opposite of pronation and involves turning the palm upwards is known as supination. Supination occurs when the forearm rotates outward, allowing the palm to face forward or upward. This motion is significant in various physical activities and exercises, as it affects grip and power during lifting or other movements.

In contrast, rotation, circumduction, and extension refer to different types of movements. Rotation involves turning around an axis, which can include pronation but is not limited to hand position. Circumduction is a circular movement that combines flexion, extension, adduction, and abduction, while extension refers to the straightening movement that increases the angle between body parts, typically at joints.

Understanding supination is essential for Force Fitness Instructors as it plays a role in technique during various exercises, ensuring that individuals maintain proper form and prevent injuries.
