The term that describes the bottom surface of the foot is "plantar." This terminology is derived from anatomy, where the plantar surface refers specifically to the sole of the foot. It is essential for group fitness instructors to understand this terminology as it relates to movement, exercise selection, and client communication regarding foot mechanics, injury prevention, and proper footwear.

The other terms have different meanings in anatomical context. "Dorsal" refers to the upper surface of the foot (the top side), which is opposite to the plantar surface. "Distal" is a term used to describe a position further away from the point of attachment or origin of a limb, and while it can be relevant in discussions of limbs and movements, it does not refer to a surface of the foot. "Palmar" pertains to the palm side of the hand, which again, is unrelated to the bottom surface of the foot. Understanding these distinctions is crucial for effective teaching and ensuring safe exercise practices.
