Which of the following movements is not typically aligned with the sagittal plane?

The sagittal plane divides the body into left and right halves and is associated with movements that occur forward and backward. Flexion and extension are primary movements within this plane; flexion decreases the angle between body parts, while extension increases it. Walking involves sequential extension and flexion of the hips, knees, and ankles in a forward motion, which also aligns with the sagittal plane.

In contrast, lateral raises involve movement away from and towards the midline of the body, which occurs in the frontal plane. This is characterized by movements such as abduction and adduction. Therefore, lateral raises are not aligned with the sagittal plane, making this the correct choice. Understanding the orientations of these planes helps clarify movement types and their respective characteristics, allowing for a better grasp of biomechanics.
