World Jeet Kune Do Federation, also founded by Carter Hargrave, offers a DVD ranking system that is best both in sales and content. Hargrave did a revolutionary work when creating these videos because he managed to conceive them to be just like private lessons with him. They are nothing like other videos available on the market. Each one is focused on training for a certain rank level and they are all made by certified instructors. Once the student orders them he can start training at his own peace and when ready, he just has to record the moves he learned and to send them back. Hargrave personally grades all the students and takes the time to offer them advice on the things they should correct or improve at their moves. DVD training is also available for those interested in American Combat Kempo. Carter Hargrave MMA as in Bruce Lee Jeet Kune Do has often been termed the original MMA.
