Golf Swing & Body Mechanics
The goal of the golf swing is to direct as much kinetic energy as possible into the club head so when it comes into contact with the ball, all of the energy will transfer to the ball, sending it into flight. Before a swing is taken the golfer first adopts their stance. This is usually a partial crouch because it allows for a more effective range of movement whilst also preloading the muscles. The stance is critical in making sure that the golfer has a low center of gravity in order that they may remain balanced throughout the swing path. The swing starts with the arms moving back in a straight line. When the club head reaches the level of the hip, two things happen: there is a stern wrist cock that acts as a hinge along with the left knee (for a right-handed swing), building up its torque by moving into the same line as the belly button before the start of the upswing.
As the golfer's hips shift towards the target and begin rotate, the right elbow will drop straight down, hugging the right side of the golfer's torso. As the right elbow drops, the wrists begin to snap through from the wrist cock in the backswing. A solid extension of the arms and good transfer of body should put the golfer leaning up on his right toe, balanced, with the golf club resting on the back of the golfers neck. Importantly, all of the movements occur with precise timing, while the head remains completely still with eyes focused on the ball throughout the entire swing.
