Bottom
of Swing Arc. (Changed-
22/04/2010)
I do not consider the down swing movement to
be fully completed until the club head reaches the bottom of the
swing arc, therefore during the down swing movement you concentrate
on swinging the club head so that it stikes the ball with a descending
blow thus compressing the golf ball, this will automatically cause
the club head to swing to the bottom of the swing arc - a position
that is well after the ball has been struck.
However in order to perform this action correctly,
you must keep the head
firmly fixed in the original address position until well after the
ball has been struck and the right heel firmly on the ground until
just before the club head strikes the ball.
If you allow the head to sway away from the original
address position during the back swing movement and fail to return
the head to the original address position at the precise moment
the club head strikes the ball you will almost certainly his the
ground before you strike the ball. ( See
below for further details.)
Bottom of the Swing Arc.
This
Photograph shows the difference between the way High Handicapped
golfers and Professional golfers strike the ball.
The bottom of the swing arc for the average PGA Tour player
is approximately four inches in front of the golf ball.
However in contrast, the bottom of the swing arc for 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 for the
bottom of the swing arc.
In other words, if you want to break a scoring barrier, focus
on improving your club's position through the impact zone so that
the bottom of your swing arc is four inches beyond the ball position.
Therefore you must focus on striking the ball with
a descending blow thus fully compressing the golf ball - this will
ensure that the club head swings to the bottom of the swing arc
- which is well after the ball has been struck!!
This also applies to the short game.

Digest"
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.
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 then
continued to rotate the upper body unit beyond the original address
position, you will note that as long as you hold the height of the
body at a constant level, 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 only applicable as long as
the golfer ensures that head
remains firmly held in the original address position throughout
the complete golf swing movement. Why is it so important?? -- let
me explain.
If your head moves ahead of the
original address position during
the down swing movement ( 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 also
swayed slightly towards the target area, thus causing the bottom
of the swing arc to move forward by the same amount.-- However
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 your head sways
away from the original address position during the back swing movement
( away from the target)
and remains in this position
until the precise moment the club head makes contact with the ball,
it means that the whole body has swayed slightly away from the target
area, thus causing the bottom of the swing arc to move backwards
by the same amount.- However
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"
So concentrate on holding the
head in the original address position from the moment you begin
the back swing movement - right through until the follow through
movement has been completed.
