柔術
Jiu-Jitsu
Brazilian Jiu Jitsu offers a great way to improve your cardio fitness, your agility, and your coordination, while learning self defense strategies and control techniques found in no other sport.
And you don’t need to be built like Tarzan to be adept at it: all you need is determination, a willingness to learn , and the heart and mindset to make it yours.
空手
Karate
Sensei Shimamoto taught Alex hard-style, aka “fighting”, which underscores the importance of balance through using one’s entire body. Traditional kicking, punching, kata, and blocking will be emphasized, as well as sparring for students who are interested and ready.
柔道
Judo
Judo means “The Gentle Way”. Its philosophy includes maximum efficiency, minimum effort and mutual benefit and welfare to all.
Judo was developed from Japanese Jiu Jitsu by Dr. Kanō Jigorō. And from Judo stemmed Brazilian jujitsu, emulating the choking and arm-bar aspects, taught in judo at the higher levels. Judo is incredibly dynamic because of the standing element whereby a fight can be won by throwing or tripping the opponent directly to their back. Judo players (“judokas”) therefore are trained to become experts in safely and painlessly taking falls.
In 1946, Judo was the first martial art to become an Olympic sport. In 2000, tae kwon do was the next (and final) martial art that became an Olympic sport. The fact that judo has been an Olympic sport for so long evidences its international reputation and popularity. Judo is regulated so the belt and practice systems are consistent throughout the globe. Judoka from 55 nations from every continent except Antarctica have won Olympic medals.
