A companion to Jeet Kune Do: A Core Structure Training Manual, this guide examines and explains the center line theory, the mechanics of developing power and speed, advanced footwork and kicks, tactics, hand strikes, and use of the elbows, knees, and head. It presents an entire chapter each on focus gloves (the most valuable piece of training equipment), sparring, grappling, and escape on the ground. The art of Jeet Kune Do is difficult to define because its founder, Bruce Lee, wanted individuals to undertake their own journey of self-discovery and self-expression, and hated referring to his art as a style or system. However, the author captures the very essence of JKD and provides the reader with an understanding of both the roots and true development of the art, as well as advanced training concepts and progressions. A glossary is also included of the fencing terminology used in JKD.
