X-Factor Lag – Fundamentals of the ESPY Golf Swing

The X-Factor Lag

Synch and Preset of the wrists develops the X-Factor lag of how the golfer’s shoulders coil in relation to the hips. This develops the golfer’s Power and Speed at impact. If you want to create lag in your golf swing, the X-Factor lag is one of two places to accomplish this. The X-Factor creates power that can be transferred through the arms, forearms, and club through impact. I have a degree in engineering, and spring coefficient was one of the subjects of our studies. The X-Factor is where the hips lag the rotation of the shoulders to create coil.

This lag is developed along the entire body. To diminish this effect of hip lag, the golfer only has to turn the hips the same amount as the shoulders are turned. A great demonstration of this is with a rubber band balsa wood airplane. If you turn the propeller clockwise six rotations, hold the torque on the propeller. Have someone go about halfway down on the rubber band and turn the rubber band about four rotations, clockwise, with their thumb and index finger. You will feel torque being reduced off the propeller. This is exactly why the golfer wants to create lag in the hips naturally.

X-Factor Lag

Balsa Wood Rubber Band Airplane

In the case of the golfer, the propeller’s hub represents the shoulders, and the rubber band is the golfer’s core muscles. Your friend’s finger, intentionally rotating the middle of the rubber band, represents the golfer intentionally rotating their hips. This eliminates lag, or the X-Factor. The golfer creating the X-Factor Lag wants to naturally coil the hips with the shoulders, instead of rotating the hips independently. The shoulders in the golf swing are rotated between 70 to 80 degrees, while the hips coil naturally between 35 to 45 degrees. Professionals can rotate their shoulders much more than the amateur’s 80-degree rotation.

The fundamental of The ESPY Golf Swing Coach uses the golfers dominant elbow to sync and preset with the shoulders. The golfer is essentially treating the elbows and shoulders as sprockets, like the sprockets on a ten-speed bicycle below. If you focus on how the ten-speed bicycle functions, you’ll notice how the size of the driving sprocket determines either how POWER or SPEED is developed.

The Sprocket Mechanics in Golf

The ESPY Golf Swing Coach takes the X-Factor Lag to a totally different level in the golf swing and maximizes it. This doesn’t just provide a mechanical advantage only, but also gives the golfer a mental advantage of confidence. Physics of Sprocket Mechanics 101 which states the following, in regard to the right-handed golfer:

  • Takeaway– the small sprocket (right elbow) rotates the large sprocket (shoulder) to develop the POWER to coil the muscles in the core body. This allows the hips to naturally respond to the coiling of the shoulders.
  • Downswing– the large sprocket (shoulders) rotates the small sprocket (right elbow) to produce SPEED and to transfer the power through the arms and forearms through the golf club at impact.

The critical sequence of Sync and Preset sets up the sprocket mechanics, using these two simple elements of placing the wrists and right elbow into the Lock position. This is demonstrated in the figure below. This also produces another advantage in golfer’s swing, confidence. Presetting and locking the golfer’s wrists and right elbow allow the golfer to establish 80 percent of the golfer’s swing. This also creates the X-Factor Lag during the Yaw element in the golfer’s swing.


EVERLAST Boxing Gloves

Yaw is an aviation term for the horizontal rotation of an object or, in this case, the shoulders around a vertical axis, or spinal axis. This three Sync, Preset, and Yaw elements create the critical X-Factor Lag component. This is all accomplished by properly presetting the EVERLAST boxing gloves wristbands with the Cam and Cam-over maneuvers setting the nodular, Ulna Styloid Process and the Flexor Capri Ulnaris muscle. This nodular and muscle sets three other pairs of muscles to initiate the golfer’s muscle memory. These three muscles are the Thenars, Pronator Quadratus and the Brachio-Radialis.
