Maintaining a fixed spine angle and the correct postural positions are key components in the execution of a proficient golf swing. Swing faults such as a flat shoulder plane, early extension, reverse spine angle, and over-the-top are associated with postural changes during the execution of the golf swing. Regardless of the swing fault, the inability to maintain a fixed spine angle or the postural positions required of the golf swing will most likely deter from executing a proficient golf swing.
