The Arm Drag is a ridiculously simple move, so simple that I don't even like thinking of it as a technique in itself! To perform it, you just need to grab, pull and guide your opponent's leading/attacking arm (yes, with more finesse than I've described it). It works on the age-old martial arts concept of using your opponent's size, weight and momentum against them. That is, when your opponent's momentum is advancing forward (or alternatively, his posture is such that his size and weight are pushing his body forward), you grab and guide him in the direction he was already moving (often pulling him off-balance). Depending on the scenario, the move can be performed with explosive force or with gentle, well-timed grace. Here's Marcello Garcia showing you how it works:
Long & Short
Personally, I like the break the arm drag down into two categories: The Long Drag, and the Short Drag. A long drag involves you gripping your opponent's wrist/forearm and guiding him a longer distance (think: Aikido) – this movement becomes especially useful in conjunction with wrist locks, sweeps and heavy striking techniques (more so from when you are standing). The Short Drag involves you gripping your opponent behind the elbow, usually resulting in less overall movement – the resulting scenario is usually ideal for shoulder barges, major hip throws and taking your opponent's back (though an elbow to the back of the head never goes amiss either!).
If timed correctly, a Long Drag can be used to lead into a Short Drag. Both are suitable for gi/no-gi applications.
Application
Arm drags are especially useful against aggressive or dirty fighters who opt to shove, tackle or grind their arms into you (usually their forearm across your face). In fact, the reason I first used an arm drag in BJJ is that someone in my guard was grinding his forearm over the bridge of my nose while punching at my ribs; I pushed his elbow across, (short) dragged his arm and took his back – love connection made.
Furthermore, arm drags are especially well-suited for smaller fighters (finally, gravity is on our side!) as their opponents often need to lean further forward (or in my case, almost crouch!) in order to efficiently attack. There's a psychological aspect that helps here too – I find that most fighters (even guys who'd otherwise opt for a more defensive/reactive style of playing) when facing a smaller opponent immediately want to dominate by rushing forward or dropping their weight on them.
As I've mentioned, the arm drag is ridiculously simple – so simple, that people get it wrong all the time! It literally is guiding your opponent in the direction he's already poised to go.

Don't make the mistake of tugging and pulling in a direction your opponent clearly isn't moving – to move him will take a lot of strength and it will tire you out in the process.
-
Remember to move your body appropriately (it's all in the hips) when attempting a long drag otherwise you may find that you've just given your opponent a better position – I think of it like this: I'm dragging my opponent a longer distance, so instead of counting on him to make the journey all by himself (your opponents aren't the most trustworthy people after all), I'll help him along – either by scooting to the side or step around myself (tai sabaki).
The Ki/Chi debate is all over online messages boards. Personally, I've never bothered to comment on any but I do very much enjoy reading the arguments from both parties (believers and non-believers). The debates do tend to get unnecessarily heated and often end up with plenty of personal insults and online forum warrior-style challenges. Which is a shame because I think it is a really interesting topic!
What is it?
Ki is explained to be a 'natural energy' or 'energy flow' which (depending on your source) either fuels life forms or is an element of life force or is a naturally present element. It is explained to be a different concept to the Chinese chi (or qi), which is allegedly less well-defined than its Japanese counterpart. Though essentially, the terms are somewhat synonymous – they're both just referring to 'natural energy-ish stuff that we can't quite explain'… the Nei Ching (credited as one of the first Chinese references to ki) describes it as a 'universal energy that nourishes and sustains all life'. Its application is most often used for healing practices (think Reiki), but it is best known internationally for its martial arts claimants. I'll be using the term ki since I'm more used to saying it (background in Japanese martial arts etc) but I'm referring to both concepts (which are really just one concept).
An alternative explanation stems from Hindu beliefs regarding chakras, which are believed to be the nexus of metaphysical and biophysical energy residing in the body. I remember reading (but not the source…sorry, it was a long time back!) that ki is said to be derived from myths/superstitions regarding the second primary chakra known as Swadhisthana (meaning "One's own abode"). The idea is that the Swadisthana is where many untapped, 'potential karmas' (samskaras) lie dormant. 
Adding to that, the second chakra is also said to home Kriya shakti (literally "strength of actions/deed/effort"), which in yogic (as in Yoga) traditions is considered to be outward manifestations of the power of thought. I further remember coming across articles that Prana (Sanskrit for 'breath'), in Vedantic philosophy, can be harnessed and physically manifested – something which was associated with the Kundalini form of yoga.
Note: For those of you that are well-versed in Hinduism, Sanskrit traditions, or yoga, please do let me know if I'm off on the details – it's been years since I read about any of the topics and since I'm in the office at the moment (yes, I write my posts when I'm not being productive) I'm writing on memory alone (…and I get hit in the head a lot)! Hmm…maybe I'll get out my copy on the Upanishads when I get home…
Popular Culture
Probably best known in its 'energy blast' form, ki in popular culture is seen as a mystical, magical form of energy drawn out of nature for use in healing and attacking. The Street Fighter series refer to it as 'Hadou', and its most famous depiction is probably Ken and Ryu's hadouken (…shame on you if you don't know what I'm talking about). The idea generally plays a big role in most fighting games and many manga, anime and movies – Fatal Fury, Naruto (which refers to it as chakra), Hero Tales etc.
I think it's this representation of ki that upsets people most. Not so much when it is used in games, anime or movies but rather when they see the equivalents in martial arts practices as in the following section.
Martial Arts – The Mystical Version
"With concentration, karatekas can move their ki up and down, so their source of energy is higher and lower. Experienced karatekas generally center their ki, in order to achieve maximum balance and power. Ki is absolutely crucial in the higher levels of karate: It gives masters the power they need to break blocks and topple much larger opponents."
- Tom Harris http://people.howstuffworks.com/karate6.htm
The mystical explanation describes ki, our energy flow, as a source of power for the martial artist. It is intangible and of some supernatural origins – it is stored in the hara (Japanese) or dantien (Chinese), about an inch or two below your navel, and can be channeled into the different parts of your body enabling you to perform feats previously not possible. Masters of ki are further able to control the energy so far as to project it from their bodies in a sort of energy wave (but lacking the flashy, attention-seeking appearance of the hadouken).
Other seemingly far-fetched claims involve using ki to manipulate objects and stop babies from falling down staircases in a fashion similar to telekinesis. As seen in the above video, attempts to prove ki blasts etc. tend to fail against people from outside of the performing dojo (at least all the ones I've seen) – various explanations have been provided for these repeated failures though none have satisfied the critics.
The Shaolin Monks are famous for performing 'iron body' techniques which demonstrate their ability to harness and channel ki through Qi-Gong training. A popular ki-demonstration used by street magician-esque martial artists (think Chris Crudelli) is that of the 'Unbendable Arm', which is in reality a feat that has less to do with esoteric energies and more to do 
with maintaining a superior biomechanical position (with some positive thinking for good measure) . As such many of these alleged ki demonstrations (even though they occasionally require a lot of skill) lack the ability to convince many on the existence of ki.
"There is nothing so strong as gentleness, and nothing is so gentle as real strength."
- Ralph W. Sockman
The Science Behind Ki
Ki is alleged to travel through the body's 12 'constant' Meridians (as well as some others but less directly). Ki flow must be in a single direction – Ascending or Descending (sometimes described as Positive and Negative) depending on whether the respective Meridian is dominated by Yin or Yang. Furthermore, the flow can be stimulated, blocked, and unblocked through concentration and physical intervention (such as pressure point attacks).
A few scientific tests have been conducted in order to test for the presence of ki but as of yet, nothing has provided any viable positive results. Various theories have propped up suggesting that ki is a way to refer to our body's natural capacity to produce electricity and plasma in which case, the healing properties of ki can sort of be accounted for…but not so much in regards to its martial application (or the ki blast).
Martial Arts – The Logical Version
It's plausible that ki doesn't really refer to ki or any mystical elements at all. Many suspicions lie in the direction that ki is really more of a metaphor than anything else. Given that in the past, the vast majority of martial arts students were uneducated and of a rural background, masters would've needed a means to better illustrate various concepts (biomechanical as well as psychological) via a comfortable metaphor that the students could easily envision. This is supported by the fact that in the Japanese language, -ki is often used without any magical or mystical connotations (for example: genki means "good health") – so there is some possibility that the concept is something that was simply lost in translation once it arrived in the West (well, except in the case of ki-blasters).
In this respect, I suppose the purpose behind ki as a conceptual metaphor in martial arts would be threefold:
-
1) Open, connect and relax the body; regulate and control breathing patterns;
-
2) Focus, develop and strengthen notions of 'intent' whilst performing techniques;
-
3) To create an understanding of the synergy between points 1) and 2).
Furthermore, the idea of ki could be (and is) very easily used as a motivator. For students who suffer from insecurities and self-doubt, the belief that they are able to draw from a greater source of power could indeed provide them with the confidence and motivation needed to excel in their art.
And then there is 'Kiai-jutsu' – that is, using the kiai (which can be understood as, but does not literally translate to, 'spirit yell') as a weapon. The kiai is essentially a loud shout used in Karate (and many other arts) in order to startle an opponent – Kawazoe's kiai is a good example of this! – as well as to teach beginning students to exhale when attacking. Of course to some, the kiai is more than just a loud shout, as denoted by the kanji it is comprised of (ki + 'ai' which is 'harmony' or 'love'), the kiai is interpreted as the projection of sound harmoniously fused with energy or spirit (hence, 'spirit yell').
Morihei Ueshiba (founder of Aikido; Note: Aiki is comprised of the kanji for Kiai written backwards) can be seen in various demonstration videos exerting the power of his kiai in which he intimidates/startles attackers to the extent of toppling them backwards. Though it should be noted, these 'attackers' are his students who probably reside a healthy fear of their teacher.
A more far-fetched example is the 17th Century story of Matajuro Yagyu, who was practically disowned for lacking talent as a swordsman (he was from the Yagyu clan, famous for its swordsmanship) and also due to some misconduct. After training with various masters, Matajuro returns to plead acceptance (but through an intermediary as his father refused to see him!); he is unable to show his skill due to the lack of an opponent. Instead he fixes his intent on some sparrows in a distant tree, he utters a loud kiai and the sparrows fall to the ground motionless. Shortly after, the sparrows regain consciousness and fly away. Matajuro went on to inherit his father's system. Note: Japanese sword schools often referred to this as 'toate no jutsu', the 'art of striking at a distance'.
A better known anecdote featuring Matajuro is his encounter with Zen sword master Tsukahara Bokuden. Matajuro asked the master, "How long will it take me to master the sword?" to which the old man replied, "About five years if you train very hard."
"And if I trained twice as hard? Then how long would it take?"
"Oh – in that case, it'll take 10 years."
Plausible Deniability Section (because I'm an optimist…ish)
As far as my experiences go – which I admit are very limited given that I've never really gone searching for ki-based arts and that I've never really devoted any amount of training to any system that is ki-based – I've not witnessed anything that would really fit the conditions of mystical, supernatural ki (did I mention that I've heard 'ki-enhanced music'? Live performance - True story) – and really, what we call 'supernatural', is really just something we haven't yet broken down in specific scientific terms.
Given that the idea behind 'ki as a metaphor' is to simplify things, it's actually pretty complicated – the synergistic kinetic energies created by our bodies when engaged in activity with appropriately conditioned intent/focus whilst maintaining a relaxation on the muscular state; ability further enhanced by the efficient regulation of respiratory patterns – something like that, right? …If I had been a master at the time, I think I would've just picked up a cane and said, "Concentrate or I'll give you a baboon's ass… okay, good – now relax your bodies".
That's not to say I have a definite belief that ki doesn't exist. I sincerely acknowledge the possibility of ki as a yet not properly understood energy/element that is processed either in nature or the human physiology itself that can be channeled through the muscles to enhance our own physiological functions (quite possibly in a similar way to oxygen). Just because we have not discovered something yet via a scientifically empirical study doesn't necessarily preclude its existence. Perhaps our understanding of ki is similar to our previous misunderstanding that the world is flat – in this case, ki would be akin to the theory of gravity.
"Human salvation lies in the hands of the creatively maladjusted."
- Martin Luthor King Jr.
I guess that makes me somewhat agnostic regarding ki. Either way, it's not something to fuss over – whether you're a diehard ki zealot or a diehard ki atheist, let those who believe, believe. And leave them be who would rather not open themselves up to the possibility. Calling for challenge matches and being a nasty web warrior (or on the other hand, a pretentiously enlightened web 'master') is just a bit lame. Don't waste your time, go train instead!
One of the earliest posts I wrote on this blog was The Triangle Hypothesis, which talked about three facets key to improving as a martial artist or fighter. For those of you who've read it, you may remember that I chose to add 'C' to the 'triangle' that many past instructors of mine had related to me. The C in this case stood for Cardio & Conditioning. The logic behind my decision was that without the right levels of fitness and body conditioning, you would be unable to fully utilise the three corners of the triangle that are Power, Speed, and Technique. This post intends to elaborate that view.
It's not by sheer randomness either - While rolling last night (my first night back! *sigh*), I was caught in a surprise Achilles ankle lock (and took a nasty elbow to the brow) and as a result, walking just doesn't feel right anymore – but instead of depressing you (my ever-emphatic reader) with a post about how my leg hurts or about how my eye looks like I was the loser of the Thriller in Manila; I'm going to write about my clever improvement of my instructors' theory with C (even though I'm pretty sure most of them just assume that C is a given).
"Minds, like bodies, will fall into a pimpled, ill-conditioned state from mere excess of comfort."
- Charles Dickens
It's no secret that the more time you spend on the mats (whether rolling, stand-up sparring or drilling), the faster you will improve. And we always hear how martial arts (especially those considered 'Traditional' styles) are all about Technique being used to overcome Athleticism, so then why have I devoted an entire post to Cardio/Conditioning? The answer in short, is that unless you have vastly superior technique to everyone else – your endurance and conditioning is going to play a factor. 
If you're looking to excel in competition (you old glory hound, you), stamina is clearly needed as you'll have to spar several rounds with relatively little rest in-between. Furthermore, if you like competing in the Absolute division (or equivalent weight-free zone), it's possible that you'll be sparring against bigger, stronger opponents who will sap the stamina out of you! There's little you can do when you're completely drained of energy against a well-trained bigger, stronger opponent so the best option is to train hard before the competition to ensure it doesn't happen.
"The time to repair the roof is when the sun is shining."
- John F. Kennedy
Non-competitive types need to be wary of the same points. You may not be competing at tournaments but note that the competition format is pretty similar to sparring sessions in training. If you don't have a high level of stamina, you won't be able to train as efficiently – i.e. Half of your 2 hour training session is wasted if you only manage to train hard for 1 hour before gassing. Though some of you may here point out that training isn't about all about 'quantity' but rather 'quality'…and you're right. However, once you begin to fatigue, your technique without a doubt begins to slowly deteriorate and while training at this point is arguably still beneficial (any training is better than none in my opinion), it is less efficient (the exception here is when you intentionally fatigue your body so as to limit your use of strength and to focus on working techniques).
And as an old boxing coach used to tell me: physical fitness improves 'mental toughness'. But is that enough? Sadly, no – as martial artists, our training all too often focuses on 'dishing out' while we spend relatively little time conditioning ourselves for the more unpleasant reverse scenario of being the 'main dish' (also quoting my old boxing coach).
In fact, I'll just explain it to you the way the old man would rant about it to me (minus some explicit wisdom)! It helps to know that Coach A was appalled by modern boxing tactics where boxers 'dance around' and 'play for points', he was a staunch believer that you punch for the knockout ("There's no such thing as a jab" he'd say).
Exercises to toughen the body have been all but forgotten. Competition has led to extensive cardio training so that fighters can last entire fights (most of which are spent running in every direction except towards your opponent). Exercises to toughen the body to withstand the rigours and demands of training and combat have been more or less discarded. Coach A used the example that most boxers have never boxed without heavy gloves and thorough wrapping – how's one expect to condition their 
hands if they're wrapped up and then further protected by a fat padded glove? Jack Dempsey makes a point of it in his book Championship Fighting: Explosive Punching and Aggressive Defense, urging the rookie boxer to train with ‘striking gloves’ or by “snipping the fingers of a pair of leather work gloves” so that he can condition his fists.
Martial arts such as Karate require even more conditioning to deal with tackles and attacks below the waist. Furthermore, developing the ability to withstand the constant (but minor) injuries sustained in training is paramount as it to an extent, dictates the level of confidence you have in the said art – so hit that makiwara until it apologises to you!
The Best Way to Cardio and Conditioning
This is one of those obvious points that's so obvious people don't notice it. The best way to develop the required stamina and conditioning for your martial art is simply to train…a lot! Not only does that ensure that you'll be developing your body in a natural way that complements your art but, you'll be doing it via means that you already love doing (the assumption here is that you enjoy training)! Make sure to train hard and push yourself in all aspects of your art, otherwise you may find your body woefully underprepared later… and please make sure to properly warm-up, stretch, and cool-down. Here's a clip of Goju Ryu 10th dan Morio Higaonna – he uses a rock to condition his fists… He's a scary man (though apparently a really nice guy too!).
The next best thing…
If you're gym/dojo/basement happens to be closed, you're a little shy about training in the park, and no one is around to play sports with, there are plenty of other options. Main thing – find something challenging that you enjoy. Personally, I hate elliptical and body building machines so I steer clear of them. Instead I prefer to swim (with the occasional bit of underwater karate when the coast is clear!) or go for runs at varying speeds (undisciplined interval training). One of my training partners hates exercise and formal workouts; he instead chooses to dance on days off from the dojo – I've joined him a couple of times… two hours of salsa/hip hop is surprisingly hard work!
Dieting
Though I know plenty of people that are constantly dieting in order to make weight, I'm not really a fan of the process. Personally, I think it’s better in the long run to follow some healthy eating habits and maintain a weight that is natural to your body even if it means that you end up at the bottom of your weight category – after all, why would anyone really want to fight someone much smaller than them (unless the ickle opponent is an absolute badass)?
Recovery Time
Whatever means of cardio and conditioning you choose, make sure to get in ample recovery time. Not only will this help your absorb information/techniques faster but it will allow you to perform at a higher rate with a lower risk of injury. And yes, sometimes you'll just need a week or two out from training – don't worry about losing the short term training as taking time off not only helps you recuperate but, it also allows your body to fully assimilate the training you have done recently (just be sensible about how often you take time off).
*Sigh!*
You may have noticed that I've used more boxing references than I usually do in this post. It's because my head is still going over Amir Khan's defeat of Marco Antonio Barrera from last week. The "Baby-faced Assassin" (Barrera) is one of my favourite boxers and it's sad to see him dominated (though I suppose I must admit, he has been on the decline for some time now). Ah well…c'est la vie!
