According to Mas Oyama, the founder of Kyokushin Karate,also knwon as the "GOD HAND", making a proper fist is essential for delivering powerful strikes and minimizing the risk of injury. Here is a step-by-step guide on how to make a fist, as described by Mas Oyama:
Start with an open hand: Begin by extending your fingers fully and relaxing your hand.
Curl your fingers: Begin curling your fingers inward, starting with your pinky finger and gradually moving towards your thumb. As you curl each finger, make sure they fold naturally, with the fingertips resting on the lower section of your palm.
Thumb placement: Once your fingers are curled, bring your thumb across the top of your fingers, resting it against the base of your index and middle fingers. The thumb should not be too tightly pressed against the fingers but should provide support and stability to the fist.
Proper alignment: Ensure that the top knuckles of your fingers (the ones closest to the fingertips) are aligned in a straight line. This alignment allows for maximum force transfer when striking.
Maintain tension and relaxation: While the fingers and thumb should be firmly closed, it is important to find a balance between tension and relaxation. Avoid excessive squeezing, which can tire your hand and reduce mobility, but also ensure that your fist is tight enough to maintain structural integrity.
Wrist position: Keep your wrist straight and aligned with your forearm. Avoid bending your wrist downward or backward, as it can increase the risk of injury upon impact.
Practice and conditioning: Making a proper fist requires practice and conditioning to develop strength and flexibility in your hand muscles. Regularly perform fist-strengthening exercises, such as squeezing stress balls or gripping exercises, to enhance your hand's ability to form a strong fist.
Remember, it is crucial to receive proper instruction from a qualified martial arts instructor to ensure you are making a fist correctly and to avoid any potential injuries.
