| The lever configuration and its application is a significant power related issue in the golf swing. There are many levers in the golf swing if you consider the body, however , we are discussing only the lever formed by the lead arm and the club shaft. The clubshaft itself is a lever as well, but we are only going to talk about the first lever. A lever is actually a simple machine. At the same time we do work on one end of the lever, the other end does work on the weight (load). A lever is used to multiply force. The golf swing is an application of a form three lever. A form three lever is arranged with the force between the fulcrum and the weight. See: the picture below |

| The lever we are most concerned with is formed by the left arm and the clubshaft. We want the left arm and clubshaft to move through impact together. Move the whole lever not the clubhead. | |||||||||||||||
| A fishing rod is an example of a form three lever. Also a hammer acts as a form three lever when it is used to drive a nail. I have always wondered why the word "casting" is used as way of explaining an improper move from the start of the downswing. If you swing a golf club like you should cast a fishing rod you will make an effective golf swing. |

| For the front arm and the clubshaft to go through together several conditions need to be present.
1.) The shoulder sockets must be free and supple. The front shoulder socket must allow the club and arm to travel (swing) freely. Once the golf swing arrives at the both arms straight condition after impact (see picture to the left) then the club needs to swing freely from the rear shoulder socket to finish. 2.) The player should feel as though the top of the club is being move NOT the clubhead. 3.) The rear side must be very willing to move through and well beyond the ball. |

| As you watch the animation notice that as the lever stays in tack the swing tends to seek "Low point" and therefore takes a good divot. The whole body ( feet, knees hips and shoulders) provides the motion which pulls the whole club through the ball. This action will never feel quick. Rather it will feel strong and slow. | |||||||||||||||
