As these photo show in a very basic form, from the address position the hips are level and during the back swing the right hip is forced into the fully raised position whilst the left hip drops.
During the down swing movement the hips gradually return to the level position before the left hip is forced to rise to the fully raided position whilst the right hip drops.
From the moment the down swing movement begins, the left leg begins to gradually straighten, thus assisting in the action of pivoting and turning the hips towards the target area in the correct manner.
During
the back swing movement, as the compact upper body unit rotates around the central core
of the spine, the muscles of the right leg remain in firm condition and
the heel of the left
foot must remain firmly on the ground thus offering a slight resistance to the movement of the upper body unit whilst the hips follow the movement of the upper body -
thus forming the whole body into a fully twisted condition.
The top class golfers rotate the shoulders and the hips around the central
core of the spine until the body is fully twisted, thus building the muscles connecting the upper body
to the lower body to a very high torsion, but if you observe these
golfers very closely, you will notice that just before the shoulders
reach the absolute end of the back swing movement, the hips are
forced to rotate towards the target area, thus creating an
overlap between the back swing and the down swing movement.
(Just to clarify, the overlap is where the shoulders are still moving
towards the end of the back swing, whilst the hips are already beginning
to rotate towards the target area, a situation that most amateur
golfers do not create.)
It is important to understand that as the hips rotate towards the target area during the down swing/follow through movement, the hips must also begin to pivot in order that the left leg is fully straightened by the time the club head strikes the ball.
It is vital that you practice this action of forcing
the hips to rotate whilst simultaneously straightening the left leg as described above, whilst compact upper body unit to forced to rotate around the axis of the spine.
Importantly, this action will ensure that the hips will
almost be fully facing the target area at the impact
position.
