Hitting
Fat is caused by incorrect posture effecting spine angle and creating
poor swing mechanics. Some of the common problems are listed below are:
Your
centre of gravity
is on your front foot so you can't move through the shot with your hips
and legs. This means your balance will be poor with your head too far
forward. With the centre
of gravity, weight will be too far forward in your stance, your
legs will move before you complete your back swing, consequently power
supplied by your arms and shoulders only.
If the centre
of balance is wrong due to disturbed posture, as indicated in the
diagram (above left) by the yellow line, your head will move too far
down on the right away from the target during the downswing or the back-swing
resulting in a distorted swing arc. You will drop your left shoulder
causing you to chop down on the ball, thus causing you to hit fat.
Poor biomechanics
will also cause you to sway your body back during your back swing and
then not coming forward to your original position during your back swing,
will result in your shot hit fat or you will top the ball through poor
distribution of weight as you swing through the ball. With poor posture
causing the wrong centre
of gravity the body will sway causing lack of balance and this will
lead to backward movement on the back-swing and forward movement on
the follow through. The hips will not rotate but will slide creating an exaggerated flat swing.
The diagram (above left) shows the typical hitting fat posture at impact with the red lines indicating the shoulder and hip relationship and the green line indicates the centre of gravity. The purple arrow indicates the direction the hips are turning at the point of impact.
Note: The centre of gravity (COG) refers to the line in the midline from your forehead to the centre of your stance. Changes in the centre of gravity, as indicated by the green line, will alter your centre of balance (COB).
The diagram, (above right), shows the typical hitting fat posture with
the centre of balance indicated by the yellow line. The swing arc is
indicated by the blue line, which in this case travels along the flat swing plane.
Point your mouse over the image to see the golfer dressed in blue which
is the correct posture (red lines indicate the centre of balance) and a straight and correct swing arc travelling along the ideal swing plane indicated by the purple line. The
correct posture should have a spine angle of 30 degrees, or as demonstrated
in the diagram by the red lines (red lines also indicate the centre
of balance), at 11 o'clock or 1 o'clock depending if you are right or
left handed. The correct swing plane is shown in purple.
Swing Summary: Changes in centre
of gravity are due to; the body leaning too far forward (i.e. the wrong spine angle) and too much weight being supported on the target-side leg.
Note: The clock diagram indicates a general swing arc for
hitting fat and both diagrams illustrate the posture at the point of impact.
