An offspring of William Chow's Chinese Kenpo Karate, Ed Parker's American Kenpo system is of of the largest and most well organized systems of Kempo. Parker took what William Chow taught him and organized every technique and movement into a format that could be broken down into levels for all students. Parker felt that innovations he added to his Kenpo eventually made up 85% of the system and thus he renamed it American Kenpo Karate. The American Kenpo system can be seen in the movies "The Perfect Weapon", and "Street Knight" starring 5th dan, Jeff Speakman, head of the American Kenpo Karate Systems and former student of Ed Parker.
