Bottom
of Swing Arc - Master
- (Changed -04/11/2008)
Bottom
of the Swing Arc.
The Photograph shows the difference between the way High Handicapped
golfers and Professional golfers strike the ball.
The swing of the average PGA Tour player bottoms out four inches
in front of the ball. The average swing bottom of a high-handicapper
is an inch or so behind the ball.
A high-handicap golfer would reduce his or her average score
by four strokes for every forward inch of improvement made on the
swing bottom.
In other words, if you want to break a scoring barrier, focus
on improving your club's position through the impact zone. This
also applies to the short game.

Point of interest
By using the muscles of the left
shoulder to pull the passive arms to the bottom of the swing
arc whilst the right shoulder
rotates under the chin, it means that the club head continues to
travel along the straight to the target line for that important
milli-second after the ball has been struck.
Therefore as this illustration points out, if you wish to strike
the ball correctly and also hit the ball straighter, you must learn
to swing the club head at a steadily accelerating tempo to the bottom
of the swing arc (until both arms are fully straightened) -
but you must keep the head
positioned so that the left eye is slightly behind the ball and
in the Fixed Frontal
condition until well after the ball has been struck and the upper
body angles must be maintained to the end of the golf swing
movement.
As the first section of this lesson illustrates, every
top class golfer aims to bottom out the golf swing about four inches
in front of the ball, except when using the driver. This
means that when playing irons and woods the ball is struck with
a descending blow, an action which imparts back spin on the golf
ball, thus giving the ball a unique flight trajectory.
For instance, when long irons
and woods are used, it creates a moderate back spin action of the
golf ball which causes the ball to curve upwards to its maximum
height until the back spin dissipates.
However, when short irons are
used it creates a much higher back spin action and therefore the
ball moves on a much more pronounced upwards curve as it soars to
it maximum height, but importantly the ball will still be spinning
at a high rate as it hits the ground, thus causing the ball to spin
back.
However the biggest benefit to
be gained by swinging the club head to the bottom of the swing arc
is that the club head is still moving at its maximum velocity as
it goes through the contact area and theoretically it should reduce
the urge to inject extra power as the club head approaches the golf
ball, thus enabling the golfer to dramatically control the power
and the accuracy of the golf shot.
Therefore by mentally removing
the golf ball from the swing path, the increased accuracy can directly
be attributed to swinging the club head with a descending blow as
it swings to the bottom of the swing arc.
Location of the Bottom of the
Swing Arc.
To understand where the bottom
of the swing arc is located, carry out the following exercise using
a three wood:-
Adopt the normal address position
and place a marker on the ground just left of the centre of your
stance, to indicate the normal ball position.
Step back a couple of inches
so that the clubhead is adjacent to the marker.
Just before you perform a back
swing movement, hold the club head so that it is just touching the
ground.
( It is important to hold the head
firmly in the original address position throughout this exercise.)
You will note that as you slowly
rotate the shoulders into the back swing movement, the club head
moves smoothly away and upwards from the ground.
( Remember to keep the elbows
as close together as it is physically possible.)
However, if you simply rotate
the shoulders, the hands
and the club head back to the original address position and at that
point stop the shoulders from moving away from the original address
position whilst the shoulder muscles continue to slowly pull the
arms/golf club towards the target area -- -- you will note that
as long as you hold the shoulders firmly in the original address
position, the club head immediately begins to dig into the ground,
thus stopping the club head from moving any further.
This indicates that the bottom
of the swing arc of the golf swing is to the left of the ball position.
The position of the bottom of
the swing arc is adjacent to the big toe of the left foot and this
is the actual point that you must focus on as you carry out the
golf swing, but this actual point is totally reliable on the golfer
making sure that the head
is firmly held slightly behind the ball at the precise moment the
club head makes contact with the ball, why?? -- let me explain.
If your head moves ahead of the
original address position (
towards the target area)
and remains in that position until the precise moment the club head
makes contact with the ball, it means that the whole body has swayed
towards the target area thus causing the bottom of the swing arc
to move forward by the same amount.
Therefore because the ball is
stationary, it means that the ball position effectively moves back
in the stance, thus creating a situation where the golfer could
possibly hit the ball "thin"
Similarly, if the head is too
far behind the original address position at the precise moment the
club head makes contact with the ball, it means that the whole body
remains too far behind the ball position, thus causing the bottom
of the swing arc to move backwards by the same amount.
Therefore because the ball is
stationary, it means that the ball position has effectively moved
forward in the stance, thus creating a situation where the golfer
could possibly hit the ball "fat"
