In other words, the only thing that the left wrist should be doing during the swing is ulnar/radially deviating. The left wrist is the opposite of the right, and it can only move in a vertical plane of motion. Additionally, this is a source of "over swinging" at the top of the swing, which throws off rhythm and timing. When the right wrist deviates in either direction, the club shaft and the right forearm will no longer remain aligned through impact. This provides maximum force through impact, and allows for maximum directional control, as all the forces are moving in one plane of motion rather than two. The reason we want to eliminate any ulnar/radial deviation of the right wrist is to keep the right forearm "on plane" throughout the swing. This is the most important component of the right wrist movement, but we must also discuss the ulnar and radial deviation of the right wrist, and why this is not recommended in the golf swing. It may seem impossible to do this, but by properly supinating/pronating (releasing) the forearms through the impact zone, this dorsiflexion ("right arm flying wedge") can remain intact. In the golf swing, the right wrist should maintain a fairly constant amount of dorsiflexion throughout. When the right wrist experiences palmar flexion, this automatically creates the opposite (dorsiflexion) in the left wrist (as described in B.J.'s video), which we know from the two-lever model post that this is a major fault in the golf swing. There is a clear reason why this is the case but requires an understanding of the two-lever model of the golf swing. In other words, the right wrist should never experience ulnar/radial deviation, and should only experience varying amounts of dorsiflexion. The right wrist and arm act as a "support" for the left arm and club, and should only move in a horizontal plane of motion. Below is one of the lessons from my Break 90 in 90 Days Training Course that further elaborates on these concepts. Homer called them the "flying wedges" because the forearms and wrists form a wedge (simply an angle), and they fly through space while maintaining their wedge shape. If either wrist falls out of its "intended" plane of motion, power and accuracy will suffer. I speak in more depth about this in my instructional series, but for now, I will be sticking with the basics.Įssentially, the flying wedge concept explains the planes of motion which each wrist can move in during the swing. In The Golfing Machine, Homer Kelley introduces a concept called the "flying wedges," which explains how the wrists and forearms must move during the golf swing. Throughout the instructional series, if I do not specify, I am referring to the motion of the left forearm, as this is the arm which controls the golf swing. For example, in the backswing, the left forearm is pronating while the right forearm is supinating. Pronation and supination are slightly confusing because they are different based on the particular forearm you are talking about. Pronation and Supination ("rolling/releasing the forearms") I will start off by defining (with pictures) the two types of wrist movement, and how the forearms move: Ulnar and Radial Deviation ("Wrist Cock")ĭorsiflexion and Palmar Flexion ("Wrist Bend") These concepts may seem dry and inapplicable at first, but after you integrate this knowledge with the rest of the instructional series, the golf swing suddenly becomes much easier. The concepts below are from The Golfing Machine, one of the most influential instructional books of our time.
