Movie Review: Kickboxer: Vengeance

This 2016 action movie turned out to be more fun that I anticipated.

The plot... who am I kidding, the plot doesn't matter. The plot holes were big enough to drive a mid-sized car through, but not a tractor trailer. There were a few surprises (after one training montage the hero goes to test his new skills and gets his butt kicked) but nothing great. 1.5 out of 5.

The action sequences were good but not great. No stuntwork to speak of (Tony Jaa can rest easy as king of stunts in the post-Jackie Chan era), but the hand to hand combat was pretty okay. Semi-realistic (sometimes one guy could take out 5 attackers, but nobody was throwing energy blasts or flying, so right in the middle of the realism spectrum as far as movies go). 3 black belts out of 5.

The acting was surprisingly lovely. A lot of work done by actual fighters and WWE people. Dave Bautista made a refreshingly charismatic villain (with very few speaking lines, but I was expecting cringeworthy cartoonishness and didn't get it). Alan Moussi was just fine as the protagonist. Sara Malakul Lane was super hot as the love interest and nothing more than that (nor was anything more required). George St. Pierre was much better as an actor, and funnier, than you'd think. I really liked Cain Velasquez' turn as a nameless thug - he's very high on my list of guys not to get into a real fight against. Jean Claude Van Damme (yes!) was fabulous, with having grown into a kind of self aware self-mockery that I can't get enough of. Now he seems like a guy I'd like to have a beer with. Gina Carano was fine, but had no action sequences to speak of, and as an actress she neither detracts nor adds to the film. Overall, 3.5 Oscars out of 5.

The cheesecake factor was low to mild, but the beefcake factor was large - lots of shirtless guys with sub-10% bodyfat running around. Almost no gratuitous female nudity, another surprise for me, coming from a low budget B-grade martial arts movie (that's not a complaint, I actually prefer my B-action movies to be nudity free, but that's a discussion for another time.

Overall, this movie wasn't good, but it was a lot better than I thought it would be. Overall rating: 3.5 Bud Light Limes out of 5.

How to Treat Yourself

I don't really believe that treats or cheat meals or other breaks in a healthy diet plan are actually necessary - in fact, I think that most people do better sticking to a plan 100% than they do, say, indulging in less healthy choices on occasion. In other words, I don't think that the desire for treats or cheats is something that builds up, like pressure over boiling water. I think that the more treats and cheats you have, the more you'll want them, not less.

I suspect that if your primary goal is weight loss or improving your health, you're better off just sticking to a healthy eating plan all of the time and NOT giving yourself planned occasions to, say, eat a cheesecake, or whatever.

But if your primary goal is a happy life, then maybe some indulging is worth it. Again, it depends on a few things - how healthy are you? If you're very sick or very obese, the tradeoff of the occasional piece of cheesecake might not be worth it. If you're fairly lean and healthy, it's a lot harder to argue that any food should be absolutely forbidden, especially if you're personally capable of indulging in moderation.

So let's assume that you are either one of those people who can't bear the thought of never having a treat again OR you're close enough to your health and body composition goals that the occasional treat is worth it (just on a cost-benefit analysis).

The way to think about cheating, or treating, is to maximize the value to cost ratio of what you indulge in.

Let me give you an example.

My kids come home from Halloween trick or treating every year with a sack full of cheap candy - things like Milky Way bars, Reese's Peanut Butter Cups, Hersheys chocolate - that sort of thing. Nothing wrong with any of it, and I'm okay with my kids indulging. However, they rarely want even half of their candy, so I'm left with a vast quantity of low cost chocolate that is mine for the taking. But I don't really like milk chocolate all that much - I mean it's fine, but it's not the sort of thing I personally crave when it's not in front of me. So I sometimes end up eating thousands of calories worth of crap that I didn't really want, except it was in front of me and available. I never really enjoy it all that much, and I feel like shit for days afterwards.

Compare that to another situation. I went to a wine bar with my lovely fiancee. She was hungry so we got a cured meat plate. It came with small pieces of mini toasted french bread. I made little stacks of cured meats and bread, which I ate with a flight of bold reds assembled by the wine store.

Guess which 'treat' I enjoyed more? And guess which one probably did more damage to my health?

That's the secret: Maximize how much your cheat or treat contributes to your happiness and minimize how much damage it does.

Here are some simple guidelines:

  1. Social over Non-Social. You will enjoy your indulgence more if it's shared - and you'll get the added benefit of being in a social situation and not having to say no to the treats being shared. 
  2. Quality over Quantity. Many people find that a really high quality food item is more satisfying. People don't usually binge eat on great chocolate - they eat entire bowls of M&M's. So when you can, treat yourself to the highest quality item you can afford, not the one that provides the most calories per dollar spent.
  3. Starches over Sugar. If you have a serious sweet tooth, eat sweets. But if you just need a treat and you are flexible, steer yourself towards, say, a tray of roasted sweet potatoes (crazy delicious) or even french fries over, for example, ice cream or a cheesecake. There is just nothing good about sugar.
  4. Nutrients over non-Nutrients. Pick the food items that have some nutritional value over those that don't. A ribeye is better than a bowl of Gummi Bears. 
A couple of more supporting ideas:
  1. If you KNOW you're going to indulge, do a hard hypertrophy workout beforehand. You might as well use those calories to heal up from a muscle fiber destroying, high volume, bodybuilding style workout. I can't promise that all the excess will go into your biceps, but some will.
  2. Once you decide to cheat or treat, DO NOT let yourself feel guilty about it. Savor it, then get back on the bandwagon of healthy eating.
Some people should stick to a healthy eating plan 100% of the time - those who are ill, athletes near their competition seasons, the very obese. Look, if you have to lose hundreds of lbs., just go without the crappy food for a while! But if you're closer to your targets, you might be happier indulging once in a while. Just make it count, savor it, and then get back to a sustainable, sensible diet.

Sparring Styles: a Training Paradigm

Have an idea I wanted to share about teaching beginners how to spar.

I've seen a few cases of younger students learning how to spar, and most of the time I see students paired up with someone of similar skill level, fully covered in foam and hard plastic shells, and told to spar. Some kids are naturally aggressive, and they tend to do better, until they use too much force, where someone will usually tell them to control themselves. Some kids never seem to really get the hang of what they should be doing (I was one of those for a long time), and I imagine many become discouraged and quit because of it.

So I have an idea of a systematic way to train students to free spar, based on a very simple notion of the different styles that someone can use in sparring.

There are a lot of different ways to categorize fighting styles. Boxing has several - the outfighter, the boxer puncher, the swarmer - and you can read a lot of analysis of fighting careers, arguing about which fighters use which styles predominantly (almost no really good fighters are all one thing, but most also tend to fall into one category or another).

Styles are often defined by a few things:

  • Preferred range. Does the fighter 'want' to, or try to, or work to, be far away from their opponent, close in, or at a middle distance?
  • Initiative. Does the fighter try to initiate exchanges, applying pressure by continuously attacking, or do they prefer to wait for their opponent to make a move, revealing openings that can be exploited?
  • Orientation. Does the fighter fight orthodox (left hand forward) or unorthodox (right hand forward)?
  • Psychological tendencies. Is the fighter a front runner? A front runner performs very well as long as he/she seems to be winning, but quickly falls apart if the fight starts to go bad. Some fighters are the opposite, and can't seem to really 'get going' until they've been hit, preferably hit hard and hurt.
  • Risk aversion. How willing is the fighter to take a chance in order to create an opportunity?

I"m sure there are other dimensions that I've missed, but I hope I've given a rough idea of how we can determine someone's style. It's a fun exercise to identify the styles of your favorite fighters, identify the styles you like most (if you follow fight sports), identify your own style, and establish the weaknesses and strengths of each style and each matchup (some styles are stronger than others in certain matchups, like rock paper scissors).

Here I want to focus solely on Initiative.

Every sparring exchange starts from a pretty much identical place. Two people are facing each other, in some kind of ready stance, at some distance where they aren't touching. Sometimes they're bouncing in place, or circling slowly, or standing relatively still, but they're at some distance and not exchanging.

Then someone moves. Sometimes this takes a while, other times it's quick. One person attacks/ moves in/ initiates an exchange, and the other person responds.

Stylistically, some people are more likely to move/attack first, and some are more likely to wait for their opponent. I'm sure there are some people who are exactly as likely to do either. For the sake of this post I'm going to make some quick definitions.

The pressure fighter is the person who wants to move first, to initiate an attack.
The counter fighter is the person who wants to wait, to let the other 'guy' move first, and act in response to that attack (i.e. to counter).

There are some gray areas here. Does a feint count as initiating an attack? I don't want to get too bogged down, so let's agree that these distinctions are not absolute, but more like guidelines to help us make order out of the chaos of free sparring.

Sometimes two pressure fighters meet each other. This tends to look like a brawl, as you have two fighters both trying to move forward and attack at the same time. Sometimes you have two counter fighters meet, and this can be tedious and slow, as each patiently waits for the other one to lead and make a crucial mistake.

Ideally, a pressure fighter fights a counter fighter. In that situation pressure fighter has to learn to attack responsibly, knowing that the counter fighter is ready to exploit any openings in his defense, while the counter fighter has lots of attacks on which they can practice their skills - the timing and techniques of countering an attack.

So what is my system of teaching?

First, I believe nobody should free fight until they have a decent handle on the basic techniques of their style. You don't want to still be concentrating on how to throw a punch while you're trying to throw it at a live opponent who is also trying to hit you back. How long should that take? I don't have an exact number, but I'd say between six months and two years, and I'm willing to make allowances for gifted or slow students. I'm not a fan of throwing white belts into free sparring.

While the students are learning the basic techniques (how to stand, how to kick, how to punch, how to move, how to block), they should be taught a basic understanding of these styles. They should have an idea of how the pressure fighter has to move so they aren't just charging in like wild boars, flailing their arms at the opponent.

When they start to spar, beginners should NEVER fight beginners. Instead, beginners should ALWAYS fight intermediate students. BUT the beginners should be taught to ONLY fight as pressure fighters. They should always lead, always move first, and try really hard to attack without getting hit hard in return. They will learn to recognize attacks, judge distance, and move within striking distance, all the skills that they'll need as a counter fighter.

The INTERMEDIATE students that are fighting the beginners should ALWAYS fight in a counter fighter style. Counter fighting is harder - you have to recognize the attacks coming and respond, which by nature takes extra cognitive processing over just attacking with what you want to attack with. But the intermediate students already have a better sense of timing, distance, and fight awareness, because they're not new anymore - they've been learning that stuff as a pressure fighter this whole time.

So an intermediate student has a block of time to learn basics without using them, along with learning the theory of combat as a theory. Then they have a block of time to learn to be a pressure fighter responsibly - to lead and attack without getting clobbered. Then they have a block of time to learn to be a counter fighter, to react to an opponent's mistakes. Once three blocks of time have gone by the student is advanced. And just to give some perspective, I'm imagining that these blocks are somewhere between six months and a year and a half - I'm not saying anyone should be stuck in one category for a decade. And if you think the blocks should be unequal in length I have no problem with that.

An ADVANCED student should be pretty competent at everything. The ADVANCED student can fill in as a pressure fighter if some intermediate student needs a partner or as a counter fighter if a beginner needs a partner. And the ADVANCED student is ready to face other advanced students, and in those situations they can use whatever style they're comfortable with.

I also think it would be useful if two advanced students spar, and both are definitive counter fighters, they should probably agree to take turns going against type. Two really disciplined counter fighters just watching each other is a waste of training time.

A few additional points:

  • Being a pressure fighter is not an excuse to brawl or fight without control. Even if you're attacking first you should use the appropriate amount of contact and defend yourself (keep your head moving, move laterally to avoid strikes, keep your hands in responsible positions for defense, etc.)
  • I am NOT saying that either style is inherently superior. I am saying that everyone should be reasonably good at both styles, even given that everyone will probably have a preference for one over the other.
  • In every free' sparring sessions where one partner is less than advanced both partners should recognize that they have a role to play. The beginner student should never spend an entire round backing up. The intermediate student should rarely jump in on the attack (exceptions can be made). In short, everyone should have a clear notion of what, generally speaking, they're supposed to be doing.
Whether you use the notion of styles to teach sparring or not, it is a useful system for analyzing your own sparring ability and planning strategies for use in your own free sparring practice.

Kata for Athletic Development

I was reading comments on an online martial arts forum the other day, and some people were discussing the usefulness of kata. One person remarked something like, "if your kata wouldn't work on the street then they're worthless."

This is an incorrect way of looking at kata, or at training in general. It's just as wrong headed as if someone said, "if your pushups wouldn't work in a street fight then they're not worth doing."

Of course nobody is going to drop down and start doing pushups during a fight (or at least, I can't think of any possible situation where that would be smart). But we don't do pushups to practice for a fight - we do pushups to develop attributes that would help in a fight.

Kata, in my opinion, can be seen in the same light. While some kata or some parts of kata might contain movements that are useful in a fight exactly the way they are in the kata, that isn't the only criterion we should use to judge the effectiveness of kata.

I've said this before, but I think it bears repeating: when correctly done, kata practice is very useful for athletic development.

What I mean by 'athletic development' is the development of athletic qualities like strength, endurance, proper movement (using the scapula properly, hip mobility, thoractic mobility, breathing coordination, that sort of thing).

There is a lot of focus paid to kata by bloggers and guys working the seminar circuit to discuss the bunkai in kata. Bunkai are basically self defense applications for the movements in a kata - if you've ever trained traditional kata, you know that there are a LOT of movements that seem impractical or weird or useless, and there's a large group of very knowledgeable practitioners who try to unpack the practical uses for those movements - finding a way that those seemingly silly movements can be used in real combat situations.

Now I don't have anything negative to say about anybody who explores the practical applications of kata movements - that's fantastic work, even though I personally don't invest a lot of energy thinking about that.

But what I find interesting in kata is not the applications of certain movements to combat or self defense, but the application of those movements as exercises that develop athletic ability.

For examples:
  • Moving forward and turning in zenkutsu dachi (front stance), especially with turns of various degrees, is a lot like the lunge matrix exercises that athletes will use. You can look at taekyoku kata as a long sequence of modified lunges in varied directions.
  • Large circular overhead movements (think shuto mawashi uke) are great for mobilizing the thoracic spine, which will make all upper body movement more efficient and improve shoulder health.
  • The opening 9 moves of Seienchin, or moves 5-6 of Gekisai Sho, are great for posture and scapular control.
  • All kata, if paced properly and done vigorously, provide a form of High Intensity Interval Training.
I'm sure there are many other examples.

I first noticed this when training for my nidan promotion - I was doing a lot of kata practice (kata performance is a significant portion of our promotions), and I found that my movement during sparring was much better than it had been, and the only footwork/speed drills I was really doing was kata.

I'm not trying to claim that any kata were developed or modified specifically to improve athletic ability - I honestly have no idea if any historical figures had this in mind.

But, when you are thinking about your kata practice, and wondering why certain moves are present or what benefits you can gain from that training, it might be worth thinking at least a little bit about things like how performing those movements can improve your physical qualities, indirectly making you a better fighter, and not just how those movements are directly applicable to combat.




Dumbass Martial Arts? Maybe...

There's a facebook group called Dumbass Martial Arts (I won't link to it, though I'm sure you can find it if so inclined) that shares videos of martial arts things that are, to varying degrees, ridiculous.

Just to be clear, I have nothing against this in principle. Many martial artists deserve to be ridiculed - especially the ones who make unjustified claims about the self defense applications of their bullshit arts (you know who you are). And I understand the urge to laugh at the expense of those less knowledgeable than you are. It's fun to be in a club (traditional martial artists! Real martial artists!) that other people either don't know about or think they're in but aren't..

And you can imagine the kind of  videos they share - if you can't, go to Jack Slack's pages in Fightland and watch everything titled Wushu Watch. Fake techniques, partners that throw themselves around the room, all kinds of bullshit and craziness.

The other day there was a post in this group of a woman doing a kata in some kind of competition, with a #bullshit tag on the post.

I won't link to the video here, but the woman in question was doing a traditional kata but with a kind of XMA presentation. If you're not sure what that means, do some youtube searches around xma kata competition and see what you find. Her ibuki was a long, drawn out scream, many seconds in length. Her stances were so deep that they were obviously completely ineffective. When she kiai'ed it took minutes to end. Every kick was at least head high. It looked like kata designed to look cool to people who know nothing about martial arts.

In short, to a traditional stylist, it was somewhat painful to watch.

The comments were pretty much what you'd think - people were brutal. They said how awful she was, how she was disrespecting the art of karate, how the judges should have walked out, and so on and so on.

And, to be honest, I'm not a fan of the presentation either. It's not the way I practice karate, it's not how I want to practice karate. If I had to choose between watching that sort of kata and kata as practiced by an old school karate practitioner, with short, effective movements, realistic stances, and functional breathing, I'd prefer the latter.

However, I really dislike the level of disdain people showed this young lady.

There are two levels on which I'd defend her:
  1. She might not know better - she might have a teacher who has convinced her that what she is doing is either good traditional martial arts or effective martial arts in a self defense context, and she believed that instructor, in which case the fault is her instructor's, not hers; or
  2. She likes what she does, and while she knows that it  is neither traditional nor effective for self defense, it brings her joy.
I don't know the woman from the video, or what she thinks of her own performance. But when I watch it, I see something that isn't traditional karate, and doesn't seem very practical for self defense, but which:
  • clearly demonstrates a high level of athleticism;
  • clearly demonstrates a high degree of commitment - she clearly practiced that kata for many hours, with great focus and determination;
  • clearly contributes to her fitness and health - nobody can do kata in an XMA style and not be reasonably strong, flexible, and fit;
This reminds me of my thoughts when I first read a few articles about tricking. If you're not familiar, tricking is a practice where people work on high difficulty martial arts techniques, like jumping spinning kicks, cartwheel kicks, etc. - the kinds of pseudo-gymnastics moves that look cool but that represent only a tiny portion of traditional karate (largely because they're mostly useless in 'actual' fighting). At first I scoffed, but most guys who practice tricking don't think they're learning to defend themselves, nor do they think they're really learning traditional martial arts. They are fully aware that they're just mastering a set of skills that they think are cool, and who are we to argue with that?

I think we should ridicule or scoff at martial artists who do these XMA style or alternative (any style that doesn't seem effective) performances in two situations:
  1. If they themselves claim that what they're doing is highly effective for self defense (this puts their students in actual danger, which isn't cool);
  2. If what they're doing is orthopedically dangerous - explosive movements are inherently higher in risk, but there are correct and incorrect ways to do them, and if a particular practitioner is moving in a way that is exceptionally dangerous to practice then we should scorn them.
So for the folks over at Dumbass Martial Arts, in my humble opinion, you should lay off anyone doing kata in some crazy over the top style, UNLESS they're claiming that such a performance is better for self defense OR they're doing things that will obviously hurt them to practice. Otherwise, acknowledge that they're doing something they think is cool, even if you disagree, and either ignore them or try to enjoy their performance for what it is.

My two cents.

Osu.

Movie Recommendation - Eddie Strongman

If you have Netflix, I highly recommend Eddie Strongman, currently available on Netflix in the US. It follows a professional Strongman competitor, Eddie Hall, for a couple of years, covering his training, eating, home life, some contest results, injuries, and more about his general life and attitude.

Eddie is one of the top Strongman competitors in the world, which means he is probably one of the strongest human beings on the planet. He's also a very charismatic and lovely fellow, although his language is probably more NSFW than not.

Overall, the documentary is really engaging.

A few really interesting take home points:

  • Being an elite athlete is not about being healthy. Elite athleticism is generally speaking not good for you. The things you have to do to be the best in the world are not compatible with being a normal healthy human being. And Strongman competitors, for the most part, seem to understand that and be okay with it. They're all sacrificing their future health and fitness for a chance at glory, and there's nothing wrong with that in my opinion (although it's not a choice I would make).
  • If you want to be big and strong, eat a lot and lift heavy.
  • To achieve lofty goals you have to make sacrifices.
  • To achieve lofty goals you often have to orient every aspect of your life to achieving them.
I personally have no desire (or probably the ability) to be elite the way Eddie Hall is, but I find his lifestyle, attitude, and story kind of inspiring. I'm also a fan of strength sports.

Another interesting documentary on Netflix (you can tell I had a few spare hours this past weekend) was "The Hurt Business," which covered a year or so out of a the life of a few MMA fighters (Rashad Evans, Holly Holm, some less well known people). Also interesting, but not as compelling as Eddie Hall's story.

Why Correct Technique is Important (or is it?)

I've been involved in a couple of small debates about punching mechanics in karate - debating what the right way is to execute a punch. There are nuances to punching technique - do you move the hand or hip first, do you tense the body at impact or think of the fist/forearm as something you've thrown at the target, do you rotate at the waist or stiffen. Interestingly, people can hit very hard using many different combinations of these methods, though logically one of them must be best, at least for any given person and situation.

So here I am, self proclaimed internet guru (that title is meant to be tongue in cheek, and it means that I have no legitimate special expertise or knowledge in this area, yet I blog about it anyway), arguing with highly respected karateka from around the world about the best way to throw a punch. Why do I do this? What's at stake here?

I like to break these discussions down into two levels, in the sense that techniques can be bad in two importantly different ways:

1. A technique can be 'wrong' in the sense that executing it that way puts orthopedic or biomechanical stress on the body in a way that is likely to be injurious to a typical practitioner. These techniques may or may not 'work' on an opponent, but I don't care.

2. A technique can be 'wrong' in the sense that it is less effective than another method (slower, less powerful, less likely to prevent you from getting hit/ hurt) but doesn't meet the standards of #1.

For my favorite (and simultaneously most horrifying) example of #1, I once trained with a guy who got 'snap' into his punches and kicks by forcibly locking out at the end of the motion as hard as he could. In other words, the 'snap' was the thud of his own joints locking into full extension. That is bad. I don't care how hard he was hitting things (I have no idea if he was), that kind of technique will break your body down in undesirable ways, given enough time.

For examples of the second kind of 'worse', we have to hurt somebody's feelings. But you don't have to agree with me on particulars to agree with me on the general idea - take the sine wave body movement from tae kwon do. I think that's bad movement - slower and less powerful and less defensible than linear mechanics. But if you're a tkd practitioner and you think I'm wrong, then of course you think that linear (or maybe we should say planar) mechanics are 'worse' - either way, one of these systems of movement is worse than the other, but neither is particularly hard on your joints or connective tissue. One of them is definitely 'worse' in that second sense.

When someone is using techniques that are bad in the first sense, that is they are likely to hurt you if you perform them, then there is no argument that there's a lot at stake in figuring out that the technique is bad, fixing the problem, and perhaps even leaving your instructor over it. If you're being taught to do things that are going to break down your body you need to find a new teacher. End of story. There is nothing good about being injured regularly.

A much more interesting question, however, is what you should do about the second type of 'worse.' What do you do if you think you're being taught a less - than - best (but still not injurious to you) way of doing something?

Here, again, I'm going to divide martial arts students into two groups. The first group is people who really need to use their skills in violent situations regularly. This might include prison guards, doormen, bodyguards, people whose jobs put them into fistfight situations at least some of the time. For this group, they need pretty effective techniques. In other words, even if they don't need the absolute best technique, they certainly can't afford to experiment too much or give too much away by trying things that might not work. For them it could literally be a matter of life or death (or at least injury vs. not injury).

But for the vast majority of martial arts practitioners, our art is purely impractical. Most of us will never get into a 'real' fistfight, ever. And most of us don't even spar in such a way that having less than optimal technique is likely to get us badly hurt. For most of us, doing technique the 'best' way is completely irrelevant in any practical sense. In fact, many of us train in such a way that we could easily go our whole lives doing something 'wrong' (in the second sense of wrong, as in less-than-most-effective) and never even know it.

I, personally, definitely fall into that last group. The debates I've been having are not between 'ways that will hurt you' and 'ways that are mechanically safe' - these debates are about which of 2 (or more) methods of executing a technique are best, while they're all 'good' enough to not cause the puncher injuries. So why do I bother, given that even if I train in a less - than - best way to punch or kick, it's almost definitely never going to affect my quality of life?

The simple answer is that I enjoy thinking about these things. I personally like to study different techniques, analyze their pros and cons, and engage in debate about which way of punching (or blocking or kicking or standing) is best. It's fun for me. I love to see a UFC fighter use a weird stance or show a weird way of punching, then analyze the advantages and disadvantages of that style. And I practice this - I'm currently obsessed with the notion of holding my lead hand low, near my waist, when sparring (someday I'll write an article about why I do this and what I like about it, but I'm still working on the details).

People train for different reasons. There are lots of people who like to train but have no real interest in thinking about training. Lots of people intensively study the history and background of their art; others simply don't. Lots of people care about self defense applications, others don't.

I'm not one to claim that EVERY practitioner of martial arts should spend time thinking about the best way to punch. If you're happy learning good punching technique from your instructor, and then diligently practicing that, that's great! Maybe your instructor is teaching the 'best' way. Even if she isn't, as long as the way you're learning isn't 'wrong' in the first sense (bad for the integrity of your bodily tissues), then have at it.

But if you're interested in discussing and debating best technique, if you get excited by the idea of doing mathematical analysis of how center of mass is affected by hand position in fighting stances, if you're that kind of student of the art, then by all means, participate! Challenge the conventional wisdom (respectfully and quietly, I mean - don't interrupt your teacher in the middle of class and suggest a better way to do something. That's just rude). Practice new things and see how they work out. Maybe you'll develop something great! And maybe you won't, but that's fine too. The joy is often in the journey.

Osu.
