Which position describes the body lying horizontal with the face down?

The position where the body is lying horizontally with the face down is referred to as being prone. In this position, the front of the body is facing the ground, making it distinct from other postures. This orientation can be used in various contexts, such as during certain exercises, physical therapy, or when assessing posture. Understanding body positions like prone is important for activities such as structural training, rehabilitation, or even in yoga practices, where specific poses require the body to be positioned in this manner.

To clarify the other terms, supine describes the position when the body is lying face up, upright refers to the body being straight and vertical, and seated indicates a position where the person is sitting. These distinctions provide clarity in exercises and movements, making the understanding of body positioning essential for proper technique and safety in physical activities.
