A plank is a long, flat piece of wood, typically thicker than a board, used in construction. It can also refer to a core-strengthening exercise where you hold your body in a straight line from head to heels, like a rigid board. Imagine it as a versatile building material or a killer ab workout. It's a fundamental element in carpentry and a popular fitness move. It's more than just a piece of wood or an exercise; it represents strength, stability, and foundational support.
