Most high handicapped
golfers allow the left heel to lift off the ground as they make
a back swing movement simply because it makes it easier to complete
a "full back swing"
However, a back swing movement that is carried out whilst
keeping the heel of the left foot firmly on the ground builds
up the torsion of the muscles to their maximum with a shorter
back swing movement.
In addition, it will also result in the ball going further
and with better control.
By keeping the heel firmly on the ground, it allows you to consistently achieve the maximum amount
of torsion within the muscles of the body every time you
perform a full back swing movement, subsequently
this gives the golfer a consistent level of energy to expend as
the down swing movement is performed, thus
allowing the golfer to accurately predict the distances the ball
will fly through the air for any particular golf club.
But in addition, by keeping the left
foot firmly on the ground also restricts the swaying effect of
the upper body as the back swing movement is performed.
So if you wish to have a consistent
back swing movement, you must not allow the heel of the left foot
to lift off the ground.
In addition, during the down swing movement, you must not allow
the heel of the right foot to lift off the ground until the precise moment the club head
strikes the ball.
You must keep both feet firmly on the ground throughout the
back swing and the down swing movement.
