What plane of the body divides it into right and left portions?

The correct identification of the plane that divides the body into right and left portions is the sagittal plane. This plane runs vertically from front to back and splits the body into two symmetrical halves, creating a right side and a left side.

When referring to body planes, the sagittal plane is distinct from others such as the frontal (or coronal) plane, which divides the body into anterior (front) and posterior (back) sections, and the transverse plane, which separates the body into superior (upper) and inferior (lower) parts. Understanding these planes is essential for personal trainers, as this knowledge helps in the analysis of movement patterns and the development of effective training programs tailored to the body’s mechanics.

By recognizing that the sagittal plane specifically pertains to the right and left division, personal trainers can better understand how to target muscles and movements associated with this plane, such as flexion and extension exercises.
