Which plane of movement divides the body into left and right sections?

The plane of movement that divides the body into left and right sections is known as the sagittal plane. This plane runs vertically, separating the body into two equal halves—one side representing the left and the other the right. Movements that occur in the sagittal plane include flexion and extension, such as when performing a bicep curl or a squatting motion. This movement pattern is fundamental in activities that emphasize forward and backward motions.

The other planes of movement serve different purposes. The frontal plane, often referred to as the coronal plane, divides the body into anterior (front) and posterior (back) sections and is associated with movements such as abduction and adduction. The transverse plane (also known as the horizontal plane) divides the body into superior (upper) and inferior (lower) sections, involving rotational movements. Understanding these planes is essential for proper movement analysis and exercise programming within the Pilates method and other physical training disciplines.
