It is vital that both legs, but particularly the right leg,
remain in the original address condition of being slightly bend
throughout the back swing and the down swing movement, it must
not straighten nor must it be allowed to bend any further, the
bend in the leg that is adopted at the address position must be
maintained at all times.
The only movement the legs should make is as follows:-
During the back swing movement the left knee moves slightly
forward from the original address position whilst simultaneously
the right knee moves slightly backwards from the original address
position.
During the down swing movement, the left knee returns to the
original address position before moving slightly backwards from
the original address position as the left leg straightens, whilst simultaneously the right
knee returns to the original address position before moving slightly
forward from the original address position.
This action prevents the body lifting and dropping as the
hips rotate.
Therefore you must not allow the right leg to bend during
the down swing movement otherwise you will cause the whole body
to dip thus effectively increasing the loft of the relevant golf
club in your hand nor must be allowed to straighten.
