Chudan Koken Uke is a technique in Kyokushin karate. It translates to 'Middle-Level Wrist Block.' This technique involves using the wrist to block incoming strikes aimed at the midsection or torso. The term 'Chudan' refers to the middle level, 'Koken' indicates the wrist, and 'Uke' refers to the blocking motion. It is commonly used to intercept punches, kicks, or strikes directed towards the abdomen or ribs, deflecting them away from the body and creating opportunities for counterattacks.
