The friction grip

Problems with the grip reflex

While I'm on the topic of reflexes, I thought I'd deal with one that I've previously alluded to but which I think deserves specific attention, namely the "grip reflex".

What is the grip reflex? Briefly put, it is the human tendency to "hold on to what you've got" in times of danger or other emergency. The origins of this reflex are easy to understand; when control is of the essence (eg. in climbing, holding or pulling etc.) your capacity to keep a firm and constant grip with your hands is vital.

The problem is that this reflex can also work against you. There are times when letting go of your grip is vital. One such time is in a civilian defence encounter. As one of my colleagues at the Traditional Fighting Arts Forums is fond of saying: “When you are holding your attacker, you have one less hand to hit him with.”

But it gets more complicated than that. You also lose your ability to use that arm for deflecting oncoming attacks. Holding your opponent might mean that you are exerting some control over him/her (eg. by trapping or restraining one of his or her arms), but it also means you are simultaneously restrained in a similar way. Both of you might end up with one limb incapacitated.

Most grappling drills try to set you up so that your restraint of an opponent will put you in a better position than your opponent, but it remains a truism that grabbing someone narrows your options. There is little you can do with a hand that is already holding a grip.

Moreover, the grip reflex can be dangerous. Why should this be so?

Your grip reflex might leave you holding onto your opponent long after you’ve lost control of him or her. There are countless fights on Youtube where a “grabber” is still holding onto his opponent’s shirt while being punched in the face repeatedly. As I’ve said, there is tendency for humans to view a grip on their opponent as an “advantage” - one that should not be lightly relinquished. This becomes particularly evident in a frenzied and confused melee exchange, when you can’t be sure which arm is doing what (either your opponent’s arms or yours!).

I discuss this aspect in the video below:


A video on the grip reflex

As you can see, the simple exercise in the video demonstrates that for a brief moment you can be confused as to what has happened. Although my partner realizes that I’ve broken free of his grasp, he can’t tell (at least, he can’t tell quickly enough) which hand has broken free. And at the same time his body is telling him to “hold onto what he’s got”.

Other issues with grabbing: the need to "relax first, then move"

Even if you have good reaction speed and know when to release a hold, a strong grip means that your arm will be tense. In order to move, you must first relax. This takes time, and in the chaotic world of real combat this is time you might not have.

Don’t get me wrong: there are many instances where grabbing your opponent is important if not necessary. It’s just that grabbing comes at a cost. So how does one ameliorate this cost?

The first step is to restrict grabs only to situations where they are necessary. “But,” I hear you ask, “what if my tactics involve trapping and grappling generally - whether stand-up on ground based?” My answer lies (at least partly) in the friction grip.

The friction grip

The friction grip is a hold that relies on the friction of skin-to-skin contact to momentarily control an opponent.

Clearly this hold is nowhere near as strong as a full closed-fist grip. However it is often all you need or want. A friction grip can allow you to maintain control for the split second needed for that set-up to counter strike or put on a “permanent” lock/hold.

And it comes without any of the disadvantages of a closed-fist grip, namely that if your friction grip becomes counter-productive, you have no grip reflex to fight, and fewer muscles you need to relax in order to move. Instead, you are free to respond to your opponent’s actions with minimal hinderance.


A video in which I demonstrate arm bars in the “listening hands” drill. Note my use of friction grips rather than full grips.

In short, the friction grip is the grip you have when you’re not “gripping”. In this respect it is rather like a Clayton’s grip, except that it does control your opponent’s limb (albeit briefly). It establishes control for as long as the control is needed, and no more.

Examples of friction grips abound in the traditional martial arts. In fact, they are ubiquitous in Filipino arnis/escrima/kali, karate kata, shaolin forms and the internal arts of xingyi, bagua and taiji (I've certainly encountered them in all the arts taught at the Academy of Traditional Fighting Arts).

Just to give one example, consider the double ko ken (back of wrist) movement in the goju ryu kata sanseiru and suparinpei: many people have interpreted this move to be a physical grab, yet if you look at the shape of the bent wrist you have to conclude that any grip using this posture would be profoundly weak. So what is the explanation of this movement?

One explanation is that it is not a literal grab, but rather a friction grip that uses the hook of the bent wrist to momentarily control your opponent’s attack as you counter (using the back of your other wrist as a striking weapon) - see the video below at around 1:27 onwards:


I demonstrate moves from seiunchin and sanseiru: note my use of the friction grip from around 1:27 onwards.

Conclusion

There are many instances where full grabbing of your opponent is necessary, whether to throw, lock or hold. But full closed-fist grabs come at a hefty price. What you gain, you sacrifice in losing the use of your own hands/arms for any other purpose - partly because of the grip reflex and partly because you will need a microsecond to relax your grip before using your arms for another purpose.

Of course, any kind of attack will leave an opening. This is not good enough reason to avoid effecting the attack altogether. Rather, you should be aware of the opening and take this into consideration when effecting the attack.

So a good puncher knows that the act of punching will leave an opening to his or her face. The puncher will accordingly throw the punch when that opening is minimized (eg. when he or she is on the outside). Similarly a good grappler will only exert a full of grab once the set-up allows this to be done with relative safety and a level of predictability as to the outcome.

But a good grappler also knows not to commit too strongly or prematurely to any grab. This is where friction grips come into their own. They provide a means of temporary control; a means that is highly variable and can morph into either a full grip or a totally different movement (where the control is abandoned).

The friction grip is accordingly a vital part of any fighter’s arsenal. Traditional martial artists should, in my view, examine their forms/kata to see where such grips occur. If you haven’t done so, try it. You might be surprised at what you find.

The "flinch reflex"

Introduction

Martial artists often talk about the the "flinch reflex". Some insist on "training it out" or "getting over it" (if that is at all possible - more on that later).

Others like Tony Blauer talk about the need to "transform" this reflex - ie. to harness it and turn it into a productive reaction rather than an essentially submissive one (see his "SPEAR" methodology).

With due respect to Mr Blauer and others like him, I think the traditional martial arts have many hundreds of years head start on this idea. In this article I propose to show just how traditional techniques build on the flinch reflex so as to create a supremely effective response in civilian defence scenarios.

What is the flinch reflex?

This website defines the flinch reflex as follows:
    "The flinch response is an unconscious response to a perceived threat. Throughout human history, this survival mechanism has protected countless people from serious injury, blindness, and death. Basically, when the human body perceives a threat, the body responds to ward off the threat through a series of reflex actions. The most noticeable reflex is the defensive motion of the hands and arms, but the flinch response can also include blinking, squinting, jumping, and withdrawal."
The video below is also quite accurate in describing the flinch reflex.


A video describing the flinch response

From a traditional martial arts perspective, the most important thing to note from the above is that the flinch reflex involves 2 main elements - both of which can be productively turned into an effective response to attack. What are those elements? They are -
  1. a defensive motion of the hands; and
  2. an evasive movement by the body.
The defensive hand movement

The first part of the flinch - the defensive motion of the hands - is usually understood as some sort of "covering up" action, but in reality it could be practically anything. In my experience as a prosecutor watching countless surveillance videos of actual assaults, the defensive motion more often consists of one or both arms shooting out - not covering up.

Consider the video below of musician Glenn Danzig being punched. He exhibits a rather typical flinch reflex, and it doesn't involve any kind of "cover". Rather, it involves his left hand shooting out in an (ultimately ineffectual) attempt to stop the punch landing. The same applies to the picture at the start of this article, which is taken from surveillance footage of a vicious assault on a prison guard. In both cases, the defender throws his hand up in a protective gesture. [In both cases, the defender was agonizingly close to actually deflecting the blow, had he had any idea of how to do so - more on that in a minute.]

Even my 4 year old daughter's flinches don't involve a "cover". Just today I took her to the park and we were throwing a ball. Unfortunately she is inclined to panic when things get near her face. So she closes her eyes, pulls her body back and shoots her arms out, ram-rod straight in front of her.

In other words, the first feature of the flinch might just involve the arms trying to ward off an attack - rather than an attempt to "cover up" against it.


Musician Glenn Danzig exhibits a flinch reflex against a punch. Note his defensive arm movement.

Evasive body movement

The second feature of the flinch - evasive body movement - is something to which I think we can all relate. We physically flinch away from danger. This can take the form of a highly submissive "shrinking" or "cowering" motion. In others it manifests as nothing more than a backward lean. Certainly Danzig shows that he is far from a "shrinking violet" in that his flinch reflex involves only the slightest lean.

It is with some interest that I noted that the first video I've embedded above only contains one "genuine" flinch - and that is at the very beginning, when the assistant didn't know what the presenter was about to do. What was his finch reflex? To lean back. Afterwards his "flinches" were clearly rehearsed and these defaulted to some sort of "faux cower".

What you can expect from your flinch

So it seems to me that unless you are highly submissive by nature, you shouldn't expect your flinch reflex to default to a cowering, face-covering response. Unfortunately this is precisely what most people who teach "transforming the flinch reflex" wrongly assume.

Rather, you should expect it to involve 2 things -
  1. a lean or duck - ie. some sort of evasion; and
  2. a movement of your arm or arms upwards and outwards towards the threat.
If this is sounding familiar it should be. In a nutshell the typical flinch response is an attempt to evade an attack while intercepting/deflecting/parrying/blocking it. In other words, humans will naturally default to what I believe is the mainstay of traditional civilian defence arts, and that is "blocking with evasion". More on this in a minute.


A typical method for "transforming" the flinch reflex. Note how there is an assumption that the flinch reflex will involve a "cower" with the arms near the face. This might well be representative of submissive people, but I get the feeling it has very little to do with the average young man, never mind a trained martial artist.

Transforming the flinch reflex

So how should one go about transforming the flinch reflex into something productive? Boxers, kickboxers and savateurs - in fact all combat sports practitioners - have been doing so for years. Their answer lies almost solely in developing the skill of evasion. To do this they utilise the second part of the flinch reflex - the evasive body movement - and train it into an effective response; one that allows them to "re-enter the game".

Their lack of emphasis on the first part - the defensive hand motion - is understandable; gloves make it very difficult to use forearm deflections. Simply put, the gloves get in the way. Gloves have fundamentally changed the dynamics of combat sports relative to unarmed fighting, as I've discussed in my article "Evasion vs. blocking with evasion".

Yes, boxing and related combat sports do employ parries, checks and other defensive hand movements. However more often than not, any defensive hand move takes the form of getting the gloves to provide a simple physical barrier.

Essentially these sports choose not to focus on the first element - the defensive hand movement - and rely instead on the second element - the evasive body movement. They have taken this evasion and elevated it to an art form. Ducking, weaving, bobbing, leaning, slipping... boxers have as many terms for evasion as the Inuit have for snow, precisely because they are so good at it. Take a swing at a boxer and chances are he won't "flinch" by covering up. He'll duck and hit you back. Consider the video below and note how the boxer has honed his own "flinch reflex" into a highly productive reaction.


A boxer shows just how productively he has honed his own "flinch reflex". Note his ducking and even his defensive use of his hands.

Modern vs. traditional eastern approaches

What about the traditional eastern martial arts? They use both evasion and what I have called "blocking" - ie. the use of the forearm, hand, elbow, shoulder etc. - to deflect an attack by intercepting it and redirecting it. In addition to the arms, deflections can be effected using the legs and other parts of the body too. But it is the very nature of the flinch - and it's defensive hand motion - that means that hand/arm deflections will be your body's default response.

Many martial artists today are want to talk about harnessing the flinch reflex. However there is a general reluctance to look at the hundreds, if not thousands, of years of traditional martial arts development. Instead of looking as far back as the ancient Greeks (never mind the plethora of Chinese and Okinawan systems) to see that arm deflections and evasion can and should be used together, some people seem overly keen on creating new systems of self-defence, based on flawed assumptions about the flinch reflex and the suitability of combat sport methodology in civilian defence scenarios.

Seizing the initiative

In particular, many "reality-based" self-defence schools promote the idea of "seizing the initiative" from the outset. This is a laudable concept. In essence it urges the practitioner to act rather than react; to pre-empt or nullify an attack as it is beginning or before it has begun (assuming it is legally appropriate to do so - more on that another time). Correspondingly this approach denigrates falling back and using the arms to deflect. The latter is something one does only when every other option has been exhausted.1

But what if every other option has been exhausted? True civilian defence relates to a situation where you are being attacked - not attacking. Like it or not, you might be playing "catch up", particularly if you are caught unawares. And in that case you will flinch. The question is, will you be able to employ your flinch reflex productively and turn the tables (ie. "seize the initiative")? Or will you be overwhelmed because you've not learned to harness that reflex?2

To point out that it is not ideal to be "on the back foot" is to point out the obvious. The statement that it would be preferable to dictate the terms of a conflict in no way affects the possibility - in fact, the probability - that this luxury won't be open to you, at least initially and certainly not in every case, in a civilian defence scenario. Training to "take the initiative" from the "get-go" is a good idea, but I wouldn't be putting all my eggs into that one basket. As far as I'm concerned, there is nothing "reality-based" in an approach that fails to consider reactive defence. It denies both the reality of human nature and of conflict itself.

Put another way, a policy of "seizing the initiative" doesn't make reactive skills redundant. On the contrary, your ability to "seize the intiative" will often depend upon reactive skills.

"Untraining" the flinch

Some people say they have learned not to flinch. Rather than "react", they "act". This is a concept often aligned with the "seizing initiative" school of thought.

I am skeptical whether such a thing is at all possible. I think the flinch reflex has a lot more to do with our genetic programming than learned behaviour. And genetic programming isn't easy to "unprogram".

The flinch reflex is more akin to classical or Pavlovian conditioning (eg. saliva in your mouth when you expect food) than it is to operant conditioning (learned responses). Yes - people recoil from danger once they learn danger is present. But what they have learned is the existence of the danger - they haven't learned to recoil.

So when a child touches a hotplate that is on, he or she will recoil sharply. And the child will recoil the next time he or she absentmindedly puts a hand close to the hotplate - whether it is on or not. The child hasn't learned to recoil. The child has learned the hotplate is dangerous. The recoil is instinctive.

I'd hazard a guess and say that unlearning a flinch is about as hard as unlearning your reaction to pull your hand away from a hotplate - or unlearning your tendency to salivate in the imminent expectation of food. These are autonomic responses, not learned ones.

Clearly, people can unlearn the tendency to flinch in certain situations. So, for example, I learned not to flinch when my sensei demonstrated on me - sometimes with a live blade or other weapon. I learned to trust him and not to flinch in that instance. But I didn't unlearn the flinch reflex: what I was unlearning was just a situational flinch. There is a big difference. If a stranger attacked me with menace using the same weapon, I'd respond very differently to how I did as "uke" in the dojo. At least, I hope I would.

So I'm skeptical of unlearning the "flinch reflex". I think people can modify the nature of their flinch, but not the very tendency to "recoil from danger" when surprised.

People can even modify the flinch reflex so as to "enter" or move forwards. This is consistent with traditional martial arts techniques, particularly at an intermediate or advanced level, where forwards (or at least forwards-angled) taisabaki or tenshin (body movement or evasion) is taught as a response to attack.

And clearly people can be taught what my friend Bryson Keenan calls "stress inoculation". Not reacting to things when you don't need to (ie. overreacting) is one thing. Learning not to react when something is about to enter your eye (as opposed to whizzing past) is another. I don't know whether you can - or why you'd want to!

Conclusion

Traditional eastern martial arts are often lampooned for their "blocks". The assault comes from 3 main camps -
  1. combat sports practitioners who have adopted a valid, but glove-determined methodology of evasion without "blocking"; and
  2. "kata revisionists" who argue that "a block is anything but a block"; and
  3. certain "reality-based" practitioners who draw their inspiration from either combat sports practitioners or "kata revisionists" or both.
Yet when you look at it objectively, the flinch reflex is entirely compatible with the traditional approach of using defensive hand movements with an evasive body movement. All traditional eastern arts do is attempt to shape the flinch reflex into something more productive. Because denying the flinch reflex is pure folly. Millenia of evolution can't be overwritten by a few martial arts classes - or even decades of them. When you are surprised, you will flinch. To assume that you won't (be surprised or flinch) is just wishful thinking.

Footnotes

1. See Rory Miller's blog post here where he says:
    "Most martial artists learn blocks (and passes and parries, etc.) and evasions (ducking, slipping, weaving, bobbing, cutting the line...). For the most part, these are ineffective. Not because the actions are inefficient or the movements don't have a valid application, they are ineffective because of timing, because they are reactive."
I have great respect for Mr Miller and follow his blog. But I don’t agree with this statement. I don't think blocks and evasions are ineffective. Anything that helps you is effective.

It's true that some sort of misguided ideology/methodology that says “always start with a block even if you don’t have to” is going to be ineffective. So is a policy of “keep blocking endlessly”. But I don't know anyone who adheres to such ideas. I certainly agree with the principle that one must "seize initiative" as soon as possible; I just think that you might just have no choice but to "react" before you can "seize initiative".

So the notion that blocking and evasion are “ineffective because of timing” either:

  1. states the obvious that it is preferable to be attacking (and sets up a straw man when arguing with people like me who think blocks and evasions are necessary and useful, but not that they should be preferred when attack is available); or
  2. is inaccurate insofar as it seems to imply that you don’t need blocks or evasions (which you clearly do in some cases).

2. Curiously, while Mr. Miller argues against "reactive" strategies, it is clear from this post that he too trains the to modify the flinch reflex. And the flinch reflex is nothing if not reactive. You don't "flinch" unless you are reacting to something. You certainly don't "flinch" when facing someone who might be an attacker but who hasn't done anything yet. If you do something in such a case, it isn't a "flinch".

Accordingly it seems to me that Mr Miller and I are not really very far apart in our thinking. More than likely Mr Miller simply has a different point of emphasis. What I think we both disagree with is the apparent use of blocks and counters as separate, disjointed techniques. Rather, blocks and evasions (where they are necessary) should seamlessly integrate with an appropriate counter as soon as it is possible to do so. My opposition to extraneous hip movement is precisely because it isolates blocks and prevents them feeding into a counter - ie. it prevents them being part of a linked, flowing response that is as much "one move" as is possible in the circumstances.
