Subject: Newsletter: The Double Hip

Iain Abernethy Newsletter: 15th of March 2019
 Hi All,
 
Welcome to the third edition of the new look newsletters! An especially warm welcome to the hundreds of new members! Thanks for joining us! Thanks also to those who have been spreading the word on these newsletters!
 
The first thing I’d like to share is a clarification on the article that appeared in the last newsletter. When discussing the relationship between mindset, technique and fitness I wrote:
 
Mindset > Technique > Fitness
 
I was using the symbol “>” in its mathematical sense to mean “is greater than”. I was not using it as an arrow. The intent was therefore to say that when it comes to combative function:
 
Mindset IS GREATER THAN Technique IS GREATER THAN Fitness.
 
A number of you took “>” to be a sequential arrow to mean we should get the mindset in place, and then learn technique, and then address fitness. This is entirely understandable, especially when used “>” as an arrow elsewhere in the newsletter! This caused confusion for a number of you because such a sequential order was antithetical to what I was saying about the integrated nature of the three elements in training and practise throughout the article. Sorry about that!
 
In this newsletter, the chosen question is one on the double-hip power generation method and how it relates to kata. It’s a power generation method that I strongly endorse and I hope you find my discussion on it interesting.
 
I am always happy to share my thoughts and explain why I think and do as I do. In expressing my firmly held convictions, I am conveying what experience has shown me to be right for me and mine. I am not saying, nor do I ever say, that alternative approaches can’t be valid for others. It is always up to the individual to assess things for themselves and then decide their own way forward. However, it’s not beholden on me to temper my firmly held convictions in order to avoid the potential upset of those who believe everyone must think the same as they do. It is right that everyone does what they feel works best for them. I’m a great believer in the double-hip. In explaining why that is the case, I am not seeking to covert. Nor am I seeking to denigrate alternative approaches. I’m simply explaining my own views to the reader.
 
Thanks so much for your support of these newsletters! Your feedback about how I can best serve you is always gratefully received.
 
All the best,
 
Iain

Question: “The Double-Hip; specifically, how it applies to kata”
asked by Dustin Lundy
 
For those not in the know, the first thing I need to explain is what we mean by the “double-hip”. The double-hip was a method of power generation introduced to the UK by Shigeru Kimura (1941 – 1995). One of Kimura’s UK students was Peter Consterdine (who is one of my teachers). Peter contextualised the double-hip for both full contact competitions and pre-emptive striking. Peter is hugely influential in the applied martial arts and practical self-defence worlds; and it is because of that influence that the double-hip has been widely adopted within those communities in the UK and elsewhere.

Photos of Shigeru Kimura working with sports scientists to test power generation concepts:
 
For my part, I was sold on the double-hip the first time Peter hit me! Most people think they know what a hard punch is, but Peter has introduced countless martial artists to a whole new level of hard. I’ve been a student of Peter for a long time and the double-hip is a key part of what I do and teach.
 
The double-hip is prone to a lot of misunderstanding because people see what Peter calls “The Big A,B,C Version” and then think that is the entirety of the method. That’s a little like spending 10 minutes in your first ever karate class, assuming you have learnt it all, and then pronouncing that all karate teaches is how to make a fist and punching in horse stance. I’ve been a direct student of Peter for a long time and I know first hand that there is much more to the method than those who’ve only seen the basics appreciate. Done right, it makes you faster, more efficient and way more powerful. It is a very versatile method.
 
Always hard to describe these things in words, but the essential idea is that a central pivot is avoided. The pivot point is therefore not the spine (which results in half of the body going forward and half the body going back), but the side of the hip; such that the entirety of the body is moving in the direction of the strike. This means much more mass is behind the strike and therefore it results in a more powerful strike.
 
Once the strike has impacted, the pivot point shifts to the other side of the hip for the following strike. This transitional aspect is very important and it’s a big part of the method. Some mistakenly think pivoting from the side of the hip will slow the strikes, but my experience has been the exact opposite. The whipping of the hips, and the overlapping of the strikes, provides a higher rate of fire.
 
In addition to the pivot point being the side of the hip, the hip moves before the shoulders and arms, so a torque is generated through the body. This also ensures the maximum mass is in motion at the point of impact.
 
There are two things that humans do better than any other creature on this planet; think and throw. Chimpanzees, for example, are way stronger than us; but they can’t throw with anything like the accuracy and force that we can. Our low shoulders and the nature of our muscles make us excellent throwers. I also don’t think it’s a coincidence that we say that people “THROW punches” as opposed to “thrust punches” or anything else. We intuitively know that a “throwing action” is optimal for our physiology.
 
In addition to ensuring maximum mass in motion at the point of impact, having the hip move before the limb results in the following:
 
1) The muscle become “stretched” during the eccentric phase of the movement. The body rotates, but the limb is not yet moving. This builds potential energy in the elastic components of the muscle (our muscles do this really well which is why we are the planet’s premier throwers).
 
2) We then have the “amortization phase” during which the muscle transitions from building up energy to releasing it. If this phase lasts too long, the potential energy can be lost. The shorter the amortization phase, the more powerful strike. When striking, this happens in a fraction of a second and results in the limb moving way quicker than it otherwise would have done.
 
3) Finally, we have the “concentric phase” where the force from the contraction of the muscles is added to the release of the potential energy generated and released in the prior stages.
 
Using the muscles in this way to THROW the punch, results in maxim speed and power because we are working with our body’s physiology. Trying to simply contract our way to speed and power is far less effective because where are not making efficient use of the nature of our muscles and we lose all the energy and limb speed that the eccentric and amortization phases contribute to.
 
Some worry making use of the muscles in this way will slow the punch down (because you need to stretch the muscles before contracting, as opposed to just contracting them) but the opposite is true. The hip rotation causes the eccentric phase, the resulting build and release of energy through the elastic nature of the muscles takes place in a tiny fraction of a second. This additional energy results in the striking limb accelerating at a much faster rate. So, while the striking tool starts moving a faction of second later (which is imperceptible in-fight), it reaches the target sooner and with greater force due to the additional energy and acceleration (from the elastic nature of the muscles) and greater mass in motion due to the hip moving more of the body mass in the direction of the strike. More mass at a greater acceleration equals loads of power (Force = Mass X Acceleration).
 
When done efficiently, the end of one technique will provide the eccentric phase for the next. These effective transitions will result in a greater rate of fire because we are then “fighting on the half beat”. You therefore get huge power, more speed, and a higher rate of fire.
 
When described in text, the double-hip may sound complex and it’s almost certain the reader will not fully understand what is being described, and they may well have some false assumptions. However, it’s quite natural in practise. Its elements are commonplace in any physical motion that seeks to develop a ballistic force i.e. throwing a javelin, a golf-swing, a tennis serve, etc. We are simply contextualising this natural motion for striking. It’s also more “subtle” in appearance than one may think. The method is far from subtle in effect though.
 
The only way to really understand the method is to experience it first-hand. It’s something you need to do for yourself under the guidance of someone who gets the method. I nevertheless hope some of the above imparts a flavour of how it works for those unfamiliar with it.
 
In Dustin’s email containing his question, he explained has been working the method and has noticed a difference in impact. His question was specifically how the method can be applied to traditional kata.
 
I learnt most of my kata before I was introduced to the double-hip. While I did not consciously seek to add it into the kata, diligently practicing it in all impact work invariably meant it became a habit that did find its way into kata. While some may think that would radically alter the look of the kata, that was not my experience. This is partly because some of the aspects of the double hip (in particular, the hips moving ahead of the hands) were already part of how I was taught to move. It was therefore mainly a shift in the pivot from the spine to the side of the hip (on the motions where that was appropriate). The double-hip can be quite subtle in appearance when one gets beyond the basics, so there was not a radical change to the look of the kata. I liken this to getting a bigger engine put into a car you already own: it looks the same on the outside but performs differently.
 
The other thing to note is that the double-hip is primarily a method for maximising the power of strikes. The kata obviously contains many other methods in addition to striking. The throwing, locking, trapping, choking, etc therefore have their own optimal body movement. It would therefore be a mistake to try to indiscriminately add the double-hip to every single movement in kata. As is always the case, you need to understand the function (bunkai) of each motion in order to perform it in the most efficient way. The strikes will benefit from the double-hip; as will some grappling motions, but all. You should not seek to indiscriminately add striking concepts to non-striking movements carte blanche.
 
As a little aside, my judo coach once watched a striking only training session I had under Peter and he did spot a number of technical similarities. The hips are used differently for lots of throws of course, but generating torque and explosive drive (using Kimura’s ideas of “kick shock”; which is beyond the scope of this article) were areas of overlap. In reality, once past the initial stages of conflict, grappling and striking are often integrated of course.
 
Because there is not a clean striking / non-striking demarcation in reality, there is not such a clean demarcation in kata either. Many movements are a mix of grappling and striking i.e. holding and hitting, trapping and hitting, locking and hitting, etc. We can therefore sometimes have “competing” considerations. For example, when striking lifting the back heel can result in more body mass moving forward and hence it can give a more powerful strike. However, lifting the heel can also result in a loss of stability when grappling. So, if a movement is a mix of grappling and striking, whether the heel should be up or not will be dependent on the what is the most pressing need at that moment from that position. The same considerations exist with the extent to which the double-hip comes into play.
 
As is always the case, the double-hip represents a technical ideal for striking. However, the situation may mean we need to move away from that ideal. The trick is to move away from it a minimal amount, so we are still getting maximum impact in that scenario without compromising tactical considerations. As an example, it may be that the enemy has gripped us and pushed us against a wall such that rotating the hips in an ideal way is not possible. The option of not striking until we have the ideal is tactically unsound, so we deliver the best strike we can i.e. the pivot point may be just off centre (as opposed to the ideal side of the hip, but still better than a central pivot) and we may not get the ideal stretch and release in the muscles, but we hit them with the best possible shot from the position we were in. People who have trained with me in person will know that “restricted punching” (hitting with the best strike you can in far from ideal positions) is practised just as much as the “clean ideals” because reality requires that we have knowledge of both. We need to seek the ideal all the while accepting that reality demands we deliver the optimum in the situation as it really is.
 
I’ll now start to bring all of this together. The double-hip is the most effective method of power generation I have come across. Of course, there are very hard hitters who use alternative methods, so I’m not discounting or disparaging those methods. However, I’ve personally found it generates much more impact than any other method I’ve been exposed to.
 
The double-hip is a very natural way of moving that makes use of good physics and is in full accord with human anatomy. While the basics of it are easy to pick up, it needs to be acknowledged that there is way more to it than the initial illustrations of concept. Like anything else, tactical considerations and the exact nature of any situation may require a drift from the idealised version, but this drift needs to be as little as possible such that the maximum impact achievable in the situation “as is” is always achieved. It also needs to be understood that the double-hip can be contextualised in various ways for use in full contact fighting, pre-emption to facilitate escape, and physical self-defence. It is a method that can easily be integrated into kata. This will increase power and will not radically alter the external appearance of the kata. It also needs to be remembered that the double-hip is primarily a power generation method for striking, and hence it should not be applied to every single movement in kata because kata contains a wide array of methods. As always, the motion should be the most efficient one for the defined objective.
 
The double-hip is a big part of my teaching and practise. I teach it from day one to my beginners because it is fully integrated with all we do. It is natural, logical and it produces hard and fast hitters. My enthusiastic support of this method should not be seen as denigrating other methods. If what you are doing works for you, then you should keep doing it.
 
Personally, I have not come across an alternative power generation method that gets close to giving the same results as the double-hip. I have also found that others who have direct experience of it (have felt it or have had instruction in it; not simply watched a video online) are also keen to adopt it. The criticisms I’ve seen on it are generally from those who don’t understand the method. Some falsely worry about a slowing of strikes, an inability to deliver effective combinations, telegraphing, etc. Those with first-hand experience of the method know that none of those concerns hold true. The double-hip aids the delivery of combinations, increases the rate of fire and is imperceptible when used pre-emptively (especially when dialogue and deception are overlaid) and in-fight. If this was not the case, it would not have been adopted by such a large number of pragmatically biased martial artists (and law enforcement).
 
As with all things, reading an article or watching a video are no substitute for direct instruction over a period of time. I nevertheless hope the above has been of interest to users of the method and those with an interest in knowing more about it.

THREE KEY LEG BLOCKING THROWS:
 
This video is footage from a recent private session where we explored a number of karate throws, associated gripping, balance breaking, footwork, underlying throwing concepts, and common mistakes.
 
A leg blocking throw is one where the enemy’s centre of gravity is moved outside of their base, such that they will fall, and they are unable to move their leg to regain their balance. We break down the following in detail: Outer Reaping Throw, Inner Reaping Throw, and Inner Hooking Throw. Together these throws give a good illustration of this type of throw.

3 – Suggested App Video: Iain’s Fighting Kata
 
There is a huge amount of material in the app, so each newsletter I will suggest a video to check out.
 
The traditional kata were designed for self-defence (non-consensual violence) as opposed to fighting (consensual violence). I was asked what a modern kata for consensual violence would look like, so I made a kata called “Tai Sabaki Ichi”. This short video explains the kata and I hope you find it interesting:

As you know, the forum has great set of contributors and it’s definitely a community you should keep an eye on. I do appreciate there is loads to look at though, so each newsletter I will pick out a thread I feel will be of particular interest.
 
In this thread contributors to the forum discuss the various types of back kick, their use in self-defence, fighting, enjoyment and how this all relates to kata.
