Endless Belt Effect (2-K)

Endless Belt Effect- The change of the clubhead from Linear Motion to Angular Motion. The clubhead and belt (hands) travel at exactly the same speed; however there are two (2) different surface speeds between the pulley and the clubhead.

The belt (hands) speed never changes but the clubhead speed increases as it goes around the pulley. The hands act as the belt they must not speed up, slow down, or become jerky. The hands do not change speed during the release.

The smaller the pulley the slower you can swing. The later the delay the slower the hand speed. The faster you swing the harder it is to keep the club from flying out.

The later the delay the slower the hand speed. The faster you swing the harder it is to keep the club from flying out. 

This is directed towards the throwout action of the Clubhead providing Maximum Power. Imagine a golf club on a Belt as pictured below.

As the club reaches the pulley the hands continue around at the same speed but he Clubhead Speed increases as it goes around the pulley. The larger the pulley the slower the Clubhead Speed.

The hands represent the belt. The club is attached to the belt. When the belt starts to curve, that's when Release starts. So with a Circle Delivery Path, there is no straight line portion in the Endless Belt.
 

With a Snap Release, there would be a larger straight line portion, with a sharp turn as it reaches the curved part of the Belt.

The Clubhead speeds up instantaneously as is reaches the curved portion of the Belt. During the Linear or straight portion, the Clubhead travels at the same speed as the belt.

Remember, the Endless Belt Effect is only one concept. It should not be considered on its own. For example, during release there is extension of the Lever Assembly, which, via Conservation of Angular Momentum, means the belt has to slow down (since more mass gets further away from the centre).

The pulley is actually the release point in the downswing. The smaller the pulley the faster the Clubhead speed (Centrifugal Acceleration).

How to increase your speed

The majority of golfers think that to hit it farther they must swing harder. The reality is we must swing faster, not harder. To swing faster the speed of the hands must not increase during the backstroke and down stroke. Here's an example;

Imagine 2 pulleys, one above the other. Around these 2 pulleys is a belt, on this belt there are golf clubs attached. When the club goes around the pulley does the club speed up? Absolutely! But, did the belt speed up? NO! Think of the arms and hands as the belt, as long as they stay at a constant speed the club will automatically speed up.

By trying to swing harder and changing the backstroke and downstroke speed the club will actually slow down! This causes the surface speed to change and the result is a slowing down of the golf club. 

Try this drill - Hold the club by the Clubhead so that the grip end of the club is pointed at an imaginary golf ball. Start swinging back and forth and listen to the sound the club makes.

You'll hear a "swishing" sound. Where you hear this sound is the fastest moving point of the swing. Get the "swish" to happen past Impact, (release is a power loss). This means that the club will be accelerating at Impact! If you hear the "swish" before Impact then the club has no choice but to slow down (decelerate)! 

In reality, when the club and ball meet the club will slow down, but this is a drill to train ourselves to accelerate through Impact , not before Impact!

In addition, there has been a lot of talk about the low point of the arc. Some say it is at the sternum.

Let me just say this, if in fact this was the case then there would be no divot in front of the ball unless every ball was played back of center of the chest!  

The Low Point is, and always will be, directly in -line and under the Left (target side) shoulder!

The only exception is when the target side wrist is in an arched condition and the shoulder is behind the Impact point of the golf ball.

Then the target side wrist becomes the Fulcrum of the swing and the Low Point..ie, Brad Faxon.
