Human Weapon

Bill Duff: (referring to Higaonna Sensei's lessons) This wasn't Karate as a sport, this was Karate as war fare and self-defense. The moves were dirty, brutal and violent designed to kill or maim.

Bill Duff (referring to Karate master Higaonna Sensei) You know for a guy who is almost 70 years old to be that strong, that's absolutely incredible. The way he trains his hands, pounding stone, this guy is like the Rocky of Okinawa.

Jason Chambers: (describing the Karate move Jodan Mawashi Geri) Because the area of impact is focused on the small part of the foot, it magnifies the force of the blow making it capable of dropping 1000 pounds of force on your head. It's like getting whacked in the head with a Louisville Slugger.

Bill Duff: (describing the Karate move Gedan Mawashi Geri) The kick's power comes from the snap of the knee. The snap is created when the quadriceps, the largest muscle in the body, contracts and pulls the tendon connected to the foot over the knee. Using the knee as a pulley the strength of the quad is enough to accelerate your foot to speeds close to 30 miles per hour.

Jason Chambers: (describing the Karate move Seiken Choku Zuki) But the key is rotating your fist 180 degrees right before it strikes the intended target. The twisting snap of the arm maximizes the speed of the punch and magnifies the force of the blow by concentrating the impact on the first to knuckles of your hand. Done correctly it can deliver as much energy as a bowling ball dropped from the top of a house.
