Judo
Founded on the principle of maximum efficiency with minimum effort
The art perfected by O-Sensei Phillip S. Porter, known as the Father of American Judo
WWMAA has published "The 65 Throws of Kodokan Judo" as part of our commitment to preserving this traditional art. Our Judo program follows the authentic Kodokan curriculum while honoring the legacy of O-Sensei Phillip S. Porter, who revolutionized Judo training in America.
Judo emphasizes using leverage, balance, and technique to overcome opponents of any size or strength. Through disciplined training, students develop not only physical prowess but also mental fortitude, respect, and character.
