Justin Thomas Swing Analysis

April 5, 2017

Justin Thomas is 5’10” and 145 pounds.   How does he hit the ball so far at only 145 pounds?  An article on Momentum will be emailed soon that explains how body weight contributes to clubhead speed.

 

There are two factors that contribute to producing your maximum clubhead speed at impact.  They are:

  • Fast twitch muscles.

  • Right wrist stretch reflex 0.06 seconds before impact.

Justin’s clubhead speed at impact is around 117mph. 

 

Scientific analysis of Justin’s mechanics:

 

 

Address:

(1,2,3,4)  is the two-axis four-lever mechanics of the traditional PGA tour  setup.

 

The shaft (4) and right arm (1,2,3) form two axis.  It is impossible to rotate a two axis system on a single plane.

 

His upper arm (1), forearm (2), hand (3) and shaft (4) create four levers

 

His hand height from the ground  at address is (5)

 

 

 

 

Justin’s right upper arm at the top being parallel to the ground is excellent for creating high clubhead speed.

 

The back of his left hand and clubface point in the same direction.  This is excellent.

 

Very few tour players use this grip.

 

This is the same relationship as Moe Norman’s grip.

 

 

 

The start of his downstroke is to transfer his weight to his left side, pick up his right heel and places major stress on his lower back by spinning his hip separately from his shoulders.

 

Observe that his back is still to the target. 

 

Spinning of the hips does not add clubhead speed. 

 

Spinning of the hips ads major stress on the lower back.

 

Hips connect through the spine and rotate on different plane than the shoulders

 

 

 

At approximately 0.06 seconds before impact, the right wrist stretch reflex kicks in; the second factor in producing high clubhead speed.

 

Fast-twitch muscles are developed by swinging a driver from a very young age as fast and as hard as you can.

 

Both fast-twitch and stretch reflex are difficult to develop if you did not do them when young.

 

Most short hitting amateurs have neither. 

 

 

 

 

 

At impact, both of Justin’s heels are off the ground.  His hips are a maximum angle to his shoulder that his anatomy will allow.  This is a recipe for maximum stress on the lower back.

 

Spinning of the hips is never necessary for producing high clubhead speed.

 

Justin’s shoulders are aligned parallel to the target line.

 

 

 

 

 

In this photo I have removed Justin’s lower body from the stroke. It should be obvious that the hip rotation produces nothing but major stress on the lower back.

 

Observe how high his hands are above his hand position at address.  Timing this up and back motion is as difficult as it gets.

 

 

 

 

Justin’s feet and lower body action are extremely difficult to reproduce.   When his timing and tempo are optimum, he can play at the level he did earlier this year.  It is very hard to keep timing and tempo optimum week after week.

 

 

Why The Traditional Two-Axis Four-Lever Mechanics Require The Highest Level Of Human Coordination.

 

For over 100 years the average golf score has remained the same - close to 100 for the average male golfer. The reason is very simple. The mechanics are too complex for the average coordination ability of humans.

 

The MAJOR culprit is the grip. The interlocking or overlapping grip forms an angle between the right forearm and the shaft (two-axis).  It is impossible to rotate a two-axis system on a single plane. This eliminates all single plane swing theories - Golfing Machine, Search for the Perfect Swing, Laser light trainers and plastic swing trainers. This eliminates the need to think about a single plane in the golf swing! The traditional two-axis four-lever mechanics is on Five Planes

 

 

Using two-axis and four-levers, scientific observation shows:

  • The shoulders are rotating on one plane.

  • The arms are rotating on a second plane.

  • The hands are rotating on a third plane.

  • The clubhead is rotating on a fourth plane.

  • The clubface is rotating on a fifth plane

  • While body center is moving upward and backward; with the clubhead moving around 100 mph.

 

 

 

If the clubface varies by greater than 2 degrees as it passes through impact, you will not hit a 40-yard wide fairway.

 

The motion is simply too complex for the average human to consistently have the clubface pointing in the correct direction at impact.

 

What statistics show is that you can practice all you want, play all you want, have the best equipment traditional companies offer and you will still not score better than 97.

 

If you want to reach your potential, order the training aids and get started on the Optimum-Reproducible-Mechanics program.
