Unbendable Arm Explained

by Stephen J. Goodson The need for skeptical thinking is present in every pursuit and area of study. This need is not necessarily due to some inherent desire for man to defraud other men, but due to man’s ability to deceive himself. The Buddhists warn of self-delusion, the Taoists speak of polishing the vision, and the skeptics say…”Let me see that again.”

As a teenager, I attended a martial arts class in which one of the senior students asked for a volunteer for a special demonstration. I was volunteered. The senior asked me to hold out my arm, make a fist, and use all my strength to keep him from bending my arm. I followed his instructions. Facing me, he slipped his shoulder under my wrist, placed his forearm perpendicular and on top of my arm at the elbow crease, his other hand grabbing his wrist. He reiterated that I was to use all my muscle and strength to keep him from bending my arm. I assured him I was fully committed to the task. He then slowly pushed down on my arm and bent it. My normal recourse would have been to challenge him again at the task, but he had already suggested a change in roles. I obliged and we changed positions. On my attempt, I easily bent his arm. I felt better.

Then he said he would use a special ,energy,” developed from many years of arduous practice of his martial art, to keep me from bending his arm. He continued, saying that this “energy” was so powerful that he could foil my attempts with his arm completely relaxed.

This time, when I attempted to bend his arm, it was to no avail. His arm-no, his entire body-was relaxed and showed no signs of strain! I tried again, as he showed that his biceps were soft and completely relaxed. He was snapping his fingers and waving his hand. (Remember, I was prying down with vigor on the elbow attached to that hand.)

In awe, my questions came. He shushed me and offered me the “secret.” He told me that the power he used was “life energy,” and that it was developed through years of special mental and physical training (I must have annoyed him because I kept comparing his arm to mine-mine was bigger!). He told me I was short-sighted and that I must “look beyond the obvious.” Then he directed me to raise and relax my arm and look in the direction it was pointing, “at a point on the wall and beyond.” I was to feel my connection with the earth through my feet and legs, then relax my body and mind and extend my mind and “energy” toward that point on the horizon, reaching for it. As I did this, he slipped his shoulder under my arm and began trying to bend my arm. Exerting himself fully, he could not bend my “energized” arm. My background in sports, he said, had developed my C(energy” a little, and my performance was more successful than others because of it.

On my next attempt to do the unbendable arm, I was able to project my “energy” so well that he had a classmate hang from my “energized” arm, swinging with both feet off the ground.* Through this relaxed use of “energy,” my strength had quadrupled in a matter of minutes! The senior said his martial art was based on this kind of “energetic” strength, and that only through careful tutelage under a competent “Master” would one be able to manifest this strength through one’s entire body and to use that “energy” against an opponent. The student would have to be of high moral character because of the obvious lethality of the art. I left that evening impressed by the demonstrative use of “life energy.”

Now there is the conundrum: is this really a physical test that proves the existence of a special “life energy?” The test is quite powerful, and if you have never experienced it, I suggest you grab a partner and give it a whirl before reading the rest of the story.

As the years have passed, I have duplicated this test many times with others. I have also witnessed the test demonstrated by others as examples of Ki / Chi energy, results of positive thinking, the power of Neuro-Linguistic Programming, etc. The demonstrations vary slightly, but the results are always the same-an impressive increase of strength through the use of this technique.

The explanation of the unbendable arm is that it is not a feat of “energetics,” but of mere physical strength, albeit proper use of strength. When the demonstrator first introduces unbendable arm, you are asked to “make a fist” and/or “use all of your muscle” to keep your arm from being bent. You do this by tightening the “big-bellied” muscles of the arm-the biceps specifically. When the demonstrator applies pressure to your arm, it bends because the muscles you have engaged are not the muscles needed to resist the pressure on your arm but are, in fact, the exact muscles that move your arm in the same direction as his pressure, i.e. the biceps bend the arm.

Now don’t think that hypnosis or suggestibility are at work here, for they are not. What is at work here is your unfamiliarity with the task at hand and the directive to “use all of your muscle.” These conditions, which seem reasonable when first presented, set you up to use the wrong muscles. Once engaged, you fail the task due to improper use of your strength.

When you are “told the secret,” you are directed to open your hand and relax and to extend your energy. This is the correct set-up for the proper use of strength because it is in extending your arm that you engage your triceps muscles. Your arm cannot be bent because you are able to use the triceps muscles that extend your arm. This is the proper use of strength for the task.

The method to keep someone from bending your arm in this exercise is correct and is most impressive, but the explanation of “life energy” (or any other explanation besides the use of the triceps) is wrong.

Knowing the real secret of the unbendable arm has been very helpful to me in examining the mechanics of other martial art techniques-throws, locks, punches, pushes, etc. It has also helped me to steer clear of the “Masters” who have other tricks that lead students far off the path. In other words, do not discount a method merely because it is incorrectly explained, but beware.

    I like this idea… I think most of the “ki” exercise can be explained like this.

  2. Hey DunkenThis explanation of the ‘unbendable arm’ is the most reductionistic and Newtonian I have ever seen.Firstly, a quick overview of gross anatomy and the 44+ muscles in the upper extremity, its surrounding connective tissue, its fascia that connect to every other part of the trunk, neck, head and body, and its neural control which would arise locally and suprasegmentally, i.e. brain and brainstem, would immediately lead one to think that there’s a little more involved in holding one’s arm steady than just… the ‘triceps’.Secondly, the author contradicts himself by saying the secret is to relax and then ‘extend your energy’ and then by saying ‘the explanation of “life energy” is wrong.’ So there are different types of energies in this universe? The energy in one’s arm and that which supports all life are mutually exclusive?Thirdly, to hear this explanation is disappointing because I use and explain the unbendable arm theory myself. The body is an extension of the mind, the mind is a reflection of the environment, and the environment is nothing but pure energy; pure consciousness; and pure potential. One’s intention shapes this potential to create what one desires – if it is life supporting. It is one of the most powerful understandings one can come to and is being popularized recently by movies like, ‘The Secret’. This pure potential, this energy, allows one to be and achieve anything; to heal and self create. It’s life energy, it’s ki, it’s whatever one wants to call it. And it works through every cell of one’s being.Yes, I agree with the author to be weary of all ‘masters’ or spiritual teachers claiming to be what they’re not, but be most aware of structural neo-Darwinists because they’ll get replies like this and simultaneously fail Dr. Singh’s anatomy exam.

    Yikes, Neil.You’re quite right that the whole body is involved in movement (to expand your first criticism properly), but it’s sufficient to identify the major players in a given movement and then relate that motion to them. That’s all you really can do; I wouldn’t suggest trying to explain a simple motion to a kohai by going into the hundreds of sequential micromovements necessary to achieve it. Just referencing the triceps is clear and adequate. Also, the author only mentions one type of energy, not two; he identifies his use of ‘energy’ as synonymous with ‘life energy’ in paragraph five…before reinterpreting The Unbendable Arm in terms of biomechanics, which is the actual contrast he makes in his article.I do agree with you that the universe constitutes a single harmonious unity, but wouldn’t that actually imply that the ‘ki explanation’ and the ‘biomechanical explanation’ are really just two sides of the same coin, so to speak?

    As a scientist, I know that *all* models are wrong. The question is not whether you have found “the truth” (you haven’t), but whether the model works for what you’re trying to accomplish. Electrons aren’t really dots that zoom around protons in perfect circles, but if you were studying to be a scientist, this model might serve you well for years.My senseis, who use the mental image of “ki flowing”, can do spectacularly at both unbendable arm and just about everything else I’ve seen in aikido.Can the “triceps” explanation be more effective at aikido? Sure, it’s possible. However, none of my senseis has apparently found biomechanical explanations as useful, and so far, neither have I.It’s good to be suspicious of extraordinary claims. But it’s also good to find what works. If anatomy is your thing, maybe a biomechanical explanation is your cup of tea. I find it more confusing than helpful.I suppose I think of ki as the generalization of biomechanics. I could work out a simple acid-base chemical reaction in terms of quantum mechanics, but it’d be a lot of work, and I can get the answer I need with a simpler model. Same with ki: it’s simple enough even I can understand it. 🙂

    I have been training in Yuishinkai Aikido for the past year and a half. In this time I have seen amazing things done by my teachers. All of which they say begins with the unbendable arm. I concour with the anonymous scientist that it depends on your perspective of the technique. Its not an argument on whether or not its biomechenics or Ki energy but rather what the person who is preforming the technique believes in to see that is done profitiantly.Furthermore I would be interested in knowing what kind of biomechanics would be used in a technique such as, having 5 large men trying to push over one who is sitting cross legged on the ground extending ki. I have witnessed this done first hand and seen that no matter how hard they push the men are unable to unseat the one crossed legged. Very impressive to watch.

    robert. next time you see such a demonstration, ask if you can try. they wont let you. do you know why? because you would be able to. The people who are straining to knock over the crosslegged block have been convinced that he is useing his ki and are psychologically unable to do it. poor guys, being taught how to defend themselves physically and haveing thier minds weakened.

  8. Thomas says:

    The five students will not be able to move the sensei as he is able to redirect most of the energy directed to his body toward the ground or the other students.The skill is to master your own body (balance,position,etc.) to prevent your opponent from applying strength in a way you can not control and can not deflect.For me "ki" is simply a mental discipline involving the body.

    unbendable arm probably is related to the mother lifting the car off her child, and other such feats. I think there is a biomechanical/physiological anatomical answer. My guess it relates to disengament of muscles that distort ideal posture in the whole body, and engage tonal muscle fibres in an all over way, so that the force is transmitted all over the body, and it acts as one resilient member. In demonstrations I have seen, the unbendable arm person is not stiff or comleltly still, but some movement occurs throughout the body.

    Has anyone here actually tried it? It's not rocket surgery or brain science.Neil Bossenger: back to Anat 101. What part of the fascia in the arm connect to the nose? Or the tongue?"a quick overview of gross anatomy and the 44+ muscles in the upper extremity, its surrounding connective tissue, its fascia that connect to every other part of the trunk, neck, head and body"I would agree that a quick overview of gross anatomy is due, on your part."Fascia" is the calling card of the mountebank. It's a shorthand way of saying "I have no clue what I'm talking about."
