“Is there a comprehensive video demonstration of effective pure kenpo technique on the ground in various jiu jitsu, judo, or wrestling holds? I truly am interested in ground kenpo.”
I would definitely recommend Master Lee Epperson’s videos. Lee is an 8th Degree Black Belt in Gaijin Ryu Ju Jitsu and also holds a 5th Degree Black Belt under Grandmaster Larry Tatum in American Kenpo Karate. Lee Epperson can lock anyone up in a pretzel in about two seconds!
Besides his tremendous skills, and devotion to the martial arts, he is truly one of the nicest guys you could ever meet.
