The original art itself is a modification of Lee's first martial art style of Wing Chun Kung Fu. So many modifications in fact that it is very hard to see some of the similarities of the two systems. The blocks and hand manoeuvres such as grabbing, sticking, and energy techniques have their roots in Wing Chun but the finished product is pure JKD. JKD has had such an influence in the martial art word the even the core art of Wing Chun has adopted JKD sparring techniques. The second of the three arts in the core of original JKD is French Fencing. Who can deny the speed and agility in the art of fencing? The footwork is a combining and modifying of fencing, Wing Chun, boxing movements, placements and displacements. And the final art of Western or American Boxing for the Muhammad Ali hand manoeuvres and punches.
