Key Points

Spine flexion and extension are movements that involve bending forward (flexion) and backward (extension) at the waist.
These movements occur around a coronal axis, which runs horizontally from side to side through the body, and in the sagittal plane, which divides the body into left and right halves.
When performing spine flexion and extension, the movement occurs in the sagittal plane, with the body bending forward or backward along the coronal axis.
This is because the primary motion of the spine during flexion and extension occurs in the anterior-posterior plane, which is aligned with the sagittal plane.
