People have asked if Mike Austin mentioned the QL in my lessons. The answer is “yes”. The QL is the quadratus lumborum, the muscles which attached the pelvic bone to each side of the spine.
There’s been much study and some dispute of late as to the precise function of the QL. Some argue that it aids in lateral flexion, as in a side bend. Others say that it has little to do with that motion. What is intriguing is the studies generally agree with how Mike Austin told me to utilize the QL. Namely, when one side is activated it brings the lowest rib (the 12th rib) down toward the hip.
To get a feel, stand erect and act as if you are going to raise your left heel but don’t allow the foot to raise. You are activating the left QL.
What does that mean to us as golfers? At address the right knee (for a right hander) is flexed. You then straighten it which bumps the right hip to 4 o’clock. At the same time you utilize the QL to crimp in (concave as Mike would say) your left side. That lowers the left hip and shoulder and sets the plane upward. Now your swing can move on the previously discussed “in curve” and the path of the club will naturally move up as it travels along the upward plane set by the left hip and shoulder. But remember our past lesson. You don’t move your head. (You’re not a dinosaur!) How is that possible? You start raising you left heel which allows the turn.
