On Kuzushi and Judogis    
Our school’s approach to creating striking power is perhaps the most widely sought after element of our training and the one most widely admired by those many students who come to train with us from outside our system. There has been no shortage of practitioners from other systems who expressed a desire to acquire the punching speed and power that is so readily apparent in many of our intermediate and advanced practitioners. Oddly enough it is still quite a task to convince such practitioners to adopt our training methods despite their desire to possess the results such training confers. This is due primarily to the faulty concept that is shared by many non-practitioners and experienced players alike about the relationship between relaxation and striking power. In short, most practitioners in an effort to create maximal results perform techniques with a maximum degree of muscular tension and exert a maximal degree of effort. On the surface this seems a sound enough concept on which to base one’s training; increase the degree to which your muscles exert themselves and increase one’s efforts, to produce greater striking power. Unfortunately training results do not bear out this hypothesis well. When asked to strike a horizontally held striking target with a hammer fist even the novice is able to generate a certain degree of power, in fact, in some instances he able to create the same or even more power than an inappropriately trained practitioner. When asked to hit the target “as hard as they can” generally, although the degree of exertion is raised exponentially, the degree of impact felt by the target holder is raised not at all, very minimally, or in some instances, less than in the case of the first strike thrown. Yet if asked the practitioner will ‘feel’ he is hitting the target much harder. The simple but hard to accept fact is that perception of power and the actual creation of it are two quite different matters. Asking the same practitioner to raise his or her hand up as if brushing their hair back, thereby using only the necessary amount of force to raise one’s hand in a relaxed manner, and then asking them to loosely swing their arm down as if it were made of rubber, in the vast majority of cases, results in a much greater degree of impact power as perceived by the target holder while the practitioner exerts far less energy and thereby perceives the strike as being less powerful. Obviously the practitioner’s ‘feeling’ is less than accurate as it relates the power being produced by such strikes and yet the results are undeniable and the behaviour of the target is also readily perceived by the striker as well. Such results are found not only in the world of striking inanimate objects for fun but can also be readily discerned in simple tasks such as hammering a nail into a piece of wood. The master carpenter rarely appears to be flailing away at a head of a nail with an unfocused barrage of energy but rather utilizes long, smooth swings, accelerating as he reaches the head of the nail to ensure proper contact and direction at the point of impact. His long easy swings quickly sink the nail all the way into the wood while most of us would still be employing our shorter, jerkier, impacts in greater number to achieve the same job. The carpenter however allows the weight of the hammer to do the work for him, letting it drop while adding only a little acceleration to its natural speed in order to achieve his efficiency. He trusts in the hammer rather than in the strength of his arm to achieve the task. It seems only fitting that we should take as a model for our ‘hammer fist’ the proper use of the real thing. Relaxation is of course not the only element which contributes to power in striking. There is also rhythm, timing, speed, weight and focus. We need a good rhythm within our own body’s internal movement for it to move in a fluid and natural way. Joints and muscles must be employed in the right order and with the appropriate speed in relation to one another in order to be used to maximum effect. Rhythm provides us with the knowledge of the essence of that correct timing. The timing between our setting of our bodies into motion, and the stopping of our bodies’ motion, in relation to the moment of a strike’s impact is of crucial importance and thus the reason we spend so much time on working the relationship between when we plant our feet and when we strike in everyday practise. In our approach we look not so much at how fast a strike is thrown but at how much it accelerates to the point of impact. Stressing the increase in speed to the point of impact rather than how fast it is launched. Speed, by itself, sometimes seems all that is necessary to create power and yet we have all watched what appears to be a blinding barrage of punches thrown in a professional boxing match which produced very little ill effects on the opponent. Weight commitment is a key component in the effectiveness of strikes and body position, posture and the movement of the striker all help to create this weight commitment. Focus is also of paramount importance in the pin pointing and directing of one’s energies into a small, well chosen target. A blow thrown at a point of impact that is not carefully chosen stands a good chance of landing poorly or roughly on broader point of contact thereby reducing its impact power to some degree. Focus also allows us to choose more vulnerable targets and/or direct or energies on the most effective angles for gaining ‘purchase’ on said target. But the importance of relaxation is probably the most difficult element for beginners to comprehend and put into practice. Tension in the shoulders when punching is probably the most difficult element to eliminate from one’s movement. Undo flexion, or snapping of the elbow joint is also a challenge for those new to striking. Our approach to beginning training in throwing a straight right hand is to break one’s movement into three main steps which show the most efficient use of one’s energy; shift, turn and punch. Shifting to start the weight moving from back foot to front, turning to make good use of the centrifugal force involved in turning the torso and hips from our side stance and punching to get our arm moving last, properly supported by the movement of our bodies. Using the analogy of a person whipping out a chain, if any of the links in said chain are, stuck, fused or immobile the chain will not move as well as it would have if all links were moving freely. In the same way if any of the muscles around our joints are flexed tightly it will interfere with the speed and ease with which we are able to move and also the degree with which our force is able to be conveyed, from link to link, up from the ground into the hand or foot. In delivering a straight right hand we first get our bodies moving in a straight line, then employ circular movement by getting our upper bodies turning in a movement that is generated from the hips and lastly allow the acceleration which has been created by the prior two movements to flow through our loose, relaxed arm, moving through our fist and into the target. If we were to describe the movement employed by the arm itself it should be like a rock on the end of a rubber band. The body creates the movement, our arm is like the rubber band allowing the force to flow through it unhindered and our fist is like the rock creating dead weight which has been hurled at the target. It is an often observed phenomenon that big people tend to hit harder given the same level of skill and this is not one we would attempt to refute. However we might offer a differing reason for why this is true than the average fellow might hold to be true. Many would come to the logical conclusion that bigger athletes strike harder because they have stronger, more muscular limbs that create greater muscular power. We might argue however that the bigger skilled athlete strikes harder mostly because he has greater amount dead weight to launch into his strike and that the more relaxed and faster he gets that weight moving the heavier his strike will become. If we look to the world of professional boxing and technicians who seemed to be very relaxed when striking we could think of athletes such as Mohammad Ali, Joe Louis, Sugar Ray Leonard, Larry Holmes and George Foreman. Larry Holmes’ jab came out loose like a whip dictating the distance at which the fight would be fought, Joe Louis’ left hook was seemingly pure technique devoid of any apparent ‘muscling’ and later era Foreman appeared so relaxed and slow moving that he appeared an easy target for the younger up and comers. That is until they felt the end of one of those punches! He seemed to be moving very slowly but he was very relaxed and using pure acceleration. The ends of those fists, even in his later years, were not moving slowly at all. The late, great Any Hug of K-1 kickboxing fame, who although not known for the looseness of his punching technique made up for it in the relaxed execution of his kicks, had this telling remark to offer in describing the role of relaxation and striking as it applied to a lackluster performance in the ring, “In preparing for this fight I had taken a lot of antibiotics due to an virus and this interfered with my performance this evening. I couldn’t relax enough in the ring to fight really well.” Although obviously one cannot be relaxed all the time when one is fighting but it is one of the critical differences we can see in very experienced fighters and in fighters who seem to possess speed and power out of proportion with their apparent physical attributes. Also it is a critical that one be relaxed at the moment of striking in order to have the necessary speed to maximize the power in one’s strikes. Relaxation allows power to happen. Matt Rogers |
