In my previous article I discussed how the humble "lunge punch" (oi zuki) of karate is largely scorned by combat sports practitioners and other "pragmatic" or "reality-based" martial artists.
The classic example of this is to be found in the kata heian shodan.
Defending the step-through oi zuki
I've had various responses to my previous article, many defending the lunge punch after a step-through. But ultimately I've been unable to come up with a single video example of such a punch being executed (at least, literally) except in basics or kata. I couldn't find it in any resistant context. Neither the cage/ring, nor karate sparring/competition, nor in surveillance footage of civilian defence encounters. I couldn't find it anywhere.
That's not to say that I think it is impossible to execute such a technique – it's just rare. It's possibly rarer than I even suspected when I started writing this series of articles.
Be honest – how often have you done a "step-through lunge punch in forward stance"? Can you find a video of anyone else doing it?
Yet despite my preceding observations, in this article I don't intend to add to the chorus of disapproval of this humble basic technique (which I shall call a "step-through oi zuki" from now on for brevity's sake). Rather I intend to defend it as a training method that, while basic, is very useful and effective in conveying vital motor learning and kinaesthetic awareness. In this context it is valuable precisely because of its status as a "stem cell movement" (see my previous articles on this topic).
The shuffle oi zuki as an alternative to the step-through oi zuki
Before we get into the "stem cell" usefulness of step-through oi zuki, let us see what its "practical" or "realistic" alternatives might be.
For example, how might someone go about "improving" a kata like heian shodan to make it "more realistic" by avoiding the step-through oi zuki?
Karate has such techniques in abundance and, as you would expect, it is seen in almost every resistant context, from MMA, to karate dojo sparring, to the "street". But this "leading punch from a front foot lunge" concept doesn't really fit with a kata like heian shodan.
For example, you couldn't simply substitute "lunges" for all the full steps. Why? Because apart from altering the character of the kata beyond recognition, it would produce an absurdity: after executing the first step into the opponent with a block, you'd have to shuffle up with a lunge punch on the same arm as depicted in the adjacent pictures. [I hasten to add that this is a cut and paste – it isn't what the fellow depicted did in the original video!]
Now this would feel daft for a very good reason: somewhat dogmatically, you'd only be using one side of the body! This would necessitate time wasting as you "reload" for a punch on the same side. There is a time and place for such things, but this isn't one of them. You have two arms and legs – you might as well use both!
Quite simply, this would be a nonsense.
The gyaku zuki as an alternative to the step-through oi zuki
The most obvious other candidate for "improving" heian shodan is the classic reverse punch. Whether it manifests as a "cross" or the more classical, straight "gyaku zuki" of karate, the reverse punch is undisputed "king" of punching.
So in this context, I would see the gyaku zuki as the most "realistic" application of the opening move of heian shodan. I would execute it in the manner shown in the adjacent photographs and as discussed in my article "How "stem cell movements" in kata morph depending on your experience", ie:
I'd wedge the attack with a gedan uke while reaching in, using a hip rotation away from the attack.
Then I'd follow with a reverse punch, powered by a hip rotation into the attack.
This all makes "perfect sense" to me. Indeed, in the video embedded below I go on to demonstrate this type of movement in a continuous drill form. And yet, I would never change the kata to conform to this model. Why not? Quite simply this:
I don't believe the kata was ever meant to be used this literally.
Rather, for the reasons referred to in my first article on "stem cell movements" I believe that kata like heian shodan were meant to communicate a variety of different options - and provide the necessary motor learning to accommodate all of those options.
The "stem cell" nature of the step-through
So what is the "stem cell" purpose of the step-through oi zuki? In my view it is very simply this:
It trains you to throw your hip forwards into the attack.
What do I mean? Many karateka are familiar with the notion of throwing their hip into a reverse punch (gyaku zuki) - largely from a stationary posture. But this ignores the dynamic (ie. moving) context in which punches are typically executed (by the way, this is yet another problem with the "double hip" theory that is presently so popular). It also often focuses unduly on the "rotation" of the hips rather than the forward moment which needs to emerge from such hip use (indeed, a circular moment is, of itself, not particularly useful unless you are executing a circular technique).
So instead, I suggest that if you are using your hip to add force to your punch, you should think of "snapping the hips forwards" rather than "rotating them sideways". And you should remember to do so in the context of a movement towards your opponent (not from a stationary position). The heian shodan type step offers a unique (yet subtle and totally unheralded) opportunity to practise this.
I discuss this in the video below at around 5:18 onwards (video set to start at the right point):
In this respect you'll be using your hips in much the same way as a baseball pitcher throws his or her ball: any circular movement in the hips, torso and arms ceases as you flick the them into a straight line towards your target. If this didn't happen, the pitcher's ball would be thrown off to one side.
The more forward moment you have, the harder you hit. And the more forward moment you have, the more likely it is for this moment to drag your back foot forward - as inevitably happens with any power punch. Consider the adjacent images of Silva vs. Machida: Silva is so committed to the punch that his back foot visibly drags up almost to the line of the front foot.
[I've previously discussed that this can be a problem for martial artists in the sense that it can leave you over-extended. But then again, this is a risk you take with virtually any committed blow: if you miss, you leave a big opening. This is something every martial artist has to weigh up.]
Indeed, a punch can have so much forward momentum that your back foot overtakes your front foot - leading to... a full step!
Consider the following animated gif of Lyoto Machida throwing such a punch:
He might not be executing a "step-through oi zuki" but he is most definitely "channelling" the principles of heian shodan (amongst other kata).
So what if we wanted to develop such forward momentum in an isolated, basic forum? Would we practise our kata just with reverse punches? No, that wouldn't do it; for one thing, it would mean that the stepping component would be utterly divorced from the hip use, heavily restricting our "forward momentum" training (and focusing unduly on stationary hip rotation).
Would we allow the back leg to drag up a little or to the "level" point (as per Silva above)? I don't think so. That would be going "half way" to a "double weighted" point of instability and vulnerability - not to mention the zone where "dead time" occurs. No, I think we'd want to move through that zone as fast as possible.
So I think we would we say:
"To hell with it - let's train the hips to go all the way through to a full step!"
In "resistant" application, such training might manifest as nothing more than a more powerful reverse punch: one that is projecting forwards forcefully. Or it might involve a leg change where back foot does in fact come up to pass the front because even more hip is projected forwards (as per the adjacent gif of me performing a movement from heian shodan in a more "advanced" manner).
[In respect of the latter, this is precisely why our version of heian shodan (what we call "fukyugata") features the punch being executed in a short stance (sanchin/han zenkutsu) rather than a full forward stance: it is our concession to "realism". This however doesn't void the value of learning to step forward into a full zenkutsu dachi as you punch: the latter lesson is just more "elemental".]
Accordingly, while heian shodan (in its traditional form) might require a punch only at the very end of this "chasing" step, this is just a matter of the "stem cell movement" having to pick the most basic incarnation for its primary form.
This is because you don't want beginners to finish their punches well before they've reached their opponent (so that they end up walking into their opponents with what is, in effect, a battering ram). Rather, you want them to wait till the very end of the movement before punching (so as to "drop the bomb" at this point).
With a more advanced student, you tell them to time their punch so that it lands with their front foot.
And for yet more advanced students, the punch can be timed to land even earlier (as per Machida's example and the video below of Enoeda sensei). The "stem cell movement" permits all these permutations.
Note how Enoeda sensei launches a reverse punch that is extended almost into an "oi zuki" to effect "kuzushi". This is the sort of principle that kata like heian shodan teach at higher levels; the same principle Machida demonstrates in the above animated gif.
In my most recent articles I discussed how such "basic exercises" were analogous to "stem cell movements" - ie. movements that teach generalised biomechanical principles pertinent to all levels of experience. And these "stem cell movements" are, in their most "embryonic" state, still capable of morphing into any number of very specialised and sophisticated variants.
I hope that in this article I have established that the much maligned "step-through oi zuki" is capable of morphing into a variety of different techniques and is accordingly well worth practising.
But more than that, the movement is, in its most basic incarnation, a fantastic motor learning method - especially for brand-new beginners. This is irrespective of any "realistic" application we might give the step-through oi zuki:
For example, I've noted previously that we choose to "stay low" evenly while moving in stances for the principle reason that it adds load in training. Having full steps in such stances also adds to this load. And this is of paramount importance to the beginner who needs to develop both explosive strength in his or her legs as well as stability. Indeed, it is clear to me that fighters like Lyoto Machida owe a great deal of their own "unorthodox" MMA fighting ability to such humble kata as heian shodan.
I've copped a bit of flak for the above observation, with some querying why one wouldn't simply practise such stances "in context". My answer is this:
Such basic kata do provide a context - it's just that the context is very "formal", "basic", "fundamental", "elemental" or "embryonic". If it were more "realistic" it would just be more specialised. As it is, the context is sufficiently general to translate to any number of different, equally important, martial contexts. Its generality is directly proportional to its transferability - and is its biggest strength.
