What position does "prone" refer to in physical orientation?

The term "prone" refers specifically to a position where an individual is lying face down. In this position, the front side of the body is facing the ground, making it distinct from other positions, such as lying on one’s back, which would be described as supine. Understanding these terms is crucial in fitness instruction because they denote foundational body orientations that are often referenced during exercises, stretch routines, or rehabilitation processes. This knowledge aids instructors in effectively communicating exercise positions to clients, ensuring proper form and safety during workouts.
