Which anatomical plane divides the body into anterior and posterior sections?

The anatomical plane that divides the body into anterior (front) and posterior (back) sections is the frontal plane, also known as the coronal plane. This plane runs vertically from side to side, creating a separation between the front of the body (such as the chest and abdomen) and the back of the body. Understanding this division is crucial in Pilates, as it influences how movements and exercises are performed, particularly those that involve lateral or side-to-side movement.

The frontal plane is especially relevant in Pilates exercises that engage the body's lateral muscles, promoting balanced strength and coordination between the anterior and posterior aspects of the body. This balance is important for improving posture and stability, which are key components of Pilates training.
