Bruce Lee was essential in providing Jesse Glover with the guidance and tools that developed into Non-Classical Gung Fu. When they first met, Bruce was still primarily working with Wing Chun and other forms of traditional arts. After meeting Jesse and several others however, Bruce began modifying these traditional ideas to counter larger, stronger, fast opponents. After Bruce moved to California, Jesse continued to hone and revise the ideas he got from Bruce. In particular, he utilized the Wing Chun principles of closing, straight punching and chi sao.

Bruce Lee eventually developed his own form of martial art called Jeet Kune Do.
