Why do many Karateka have weak punches?

I love Karate as much as you do, but let's be honest here, many Karate practitioners have weak punches. Of course, power is not everything, but it's an important attribute to have along with timing, coordination, reflexes, and speed.

That being said, it's important to understand that our beloved art cannot be "blamed" for such an issue. It's not karate's fault, it's more than the individual making the punch is making it wrong. Let's examine the reasons why many karatekas have weak punches.

1. Too much muscular tension

Don't hate me, but in general, Japanese Karate styles - as compared to Okinawan styles - are rigid. As you know, Japanese people tend to be more strict, formal, disciplined and Okinawan are more relaxed, loose and easygoing. Their attitude has a direct effect on their respective Karate styles, philosophy and practice.

You probably read this before. Lao-Tzu, the famous Chinese philosopher, wrote in his equally famous book Tao-Te-Ching: "A man is born gentle and weak; at his death, he is hard and stiff. All things, including the grass and trees, are soft and pliable in life; dry and brittle in death. Stiffness is thus a companion of death; flexibility a companion of life. An army that cannot yield will be defeated. A tree that cannot bend will crack in the wind. The hard and stiff will be broken; the soft and supple will prevail."

He nailed it right on the head - rigidity is death. Whenever you are physically rigid or tense during physical activity, whether it's badminton, Karate or anything else, you lose speed, power, and energy.

People practicing basic punches in kiba-dachi stance, tends to tense up: their fists are clenched super tightly, their forearms and arms are tight, hard as steel, like if hardness meant power. That's exactly the opposite.

a) Tension slows you down

Holding tension in your fists, arms and whole body is drastically slowing your punches down. When your muscles are tense, it takes longer for the stimuli and impulses to go travel from the nervous system to the nerves and muscles. In other words, make it take too long to "deliver" your punch. When you stay relaxed while throwing your punch, you'll find that its speed is much quicker.

b) Tension makes your punches weaker

Muscular tension makes your body so tight, so stiff that it prevents the generated power to unleash into your punch fully. Think of a whip. The reason it's so powerful is that it generates power in a completely free, non obstructed manner. Rigidity and muscular tension do obstruct power.

c) Tension burns you up

When you are tense, you grow tired very quickly. Holding onto tension means your muscles are being overworked, and as such, you burn your energy supplies. When you let go of muscular tension and rigidity, you can train (or fight) for greater periods. Getting rid of that 'stiffness' in your Karate will make a big difference in your endurance.

d) Tension in your body equals tension in your mind

There is something essential that you have to understand now: rigidity of the body equals rigidity of the mind. If your body is stiff, your mind is stiff, and that's not something you want. A stiff and rigid mind doesn't flow, adapt, or react quickly and effectively. The result is delayed reactions, and delayed reactions can put you in a dangerous position during a real encounter.

The key to an effective and enduring Karate is to learn to relax. In a minute, I'll give you useful tips that will help you do precisely that.

2. Poor understanding of biomechanics

Another thing that Karate practitioners struggle with is performing movements, in this case, the punch, with the proper biomechanics or body mechanics. Every technique you perform is enhanced or diminished by the way you move and stand. Bad posture, poor ergonomics, and improper form or technique can cause bad body mechanics which will result is poor speed, power, and stability.

A poor understanding of the proper biomechanics of the Karate punch will not only significantly diminish the quality and the effectiveness of our movement itself, but also the good health of our articulations, tendons, muscles, and body as a whole.

What are proper biomechanics in Karate and martial arts?

Proper body mechanics is the harmonious, natural interaction of your muscles, bones, joints, and breathing working together to produce the ideal and most efficient movement. In the context of this article, proper biomechanics is manifested by using every part of your body correctly to deliver the punch: elbow, shoulder, legs, spine, core, and hips.

I'm sure lots of readers will say, "No, not me, I've been practicing Karate for years, I know how to punch. Come on!" You may be right, but I bet you can still improve your Karate punch's biomechanics so that you can deliver it with optimal effect.

3. Improper breathing

Unfortunately, too many Karate people don't breathe properly when delivering their punches, even experienced, seasoned practitioners! Most karatekas are not exhaling while striking; instead, they hold their breath and tighten up their entire body.

I don't mind what your excuses are, if you don't breathe properly, there is NO WAY that you are punching to your full potential. Period. If you hold your breath while delivering your Karate tsuki or exhale at the wrong time, you are preventing your body its natural ability to release energy or power, resulting in a weak punch.

What is punching power?

On a fundamental level, the primary goal of the Karate punch is to transfer as much destructive power as possible from your body to your opponent.

In other words, power, in our case punching power, is the ability to deliver enough force to render an opponent unconscious, to knock him out or to temporarily disable him by knocking the wind out of him or breaking its bones.

Knockout power is related to timing, speed, technique, precision among other factors. In physics, this power is generated by motion, and it's called kinetic energy. Scientists can measure kinetic energy by calculating the amount of "energy transferred per unit of time."

As I mentioned before, although they share similarities, Japanese and Okinawan Karate are entirely different in their application and philosophy. One particular area where they are different is their perception of power and the physicality behind it.

1. Kime

The concept of kime is at the core of Japanese Karate (mainland). In application, Kime is that instant stop at the end of your motion where you freeze your technique quickly, you know, "the snap". Kime-oriented punches are generally performed with great muscular tension (prior, during and after the strike) in most part of the body, particularly the fist, forearm, arm, and abdominals.

2. Chinkuchi

Okinawan Karate is a different beast, it's quite different from Japanese Karate in its fundamental principles and applications. In Okinawan Karate you can pretty much forget about the snap. It’s not important to stop your technique in an instant, what is more important is to transfer your energy through the opponent, and that's called Chinkuchi. The power of Chinkuchi looks more like a quick and progressive push than an explosive strike. Imagine a wave building up and unleashing on the rocks. I love using water metaphor, I really do!

3. Muchimi

Another fundamental principle at the heart of Okinawa Karate is Muchimi or Mochimi. It's a power generating principle where the practitioner's body and movements should attain the character of mochi, a popular food in Japan. Mochi is a Japanese sticky rice cake that has an elastic-like texture, almost like rubber.

The principles of Muchimi refers to the fact that the body should be relaxed and flexible like mochi. You start relaxed, and contract only at the moment of impact (not while you 'launch' your fist, ONLY at the moment of impact), then finish relaxed and decontracted. It's actually very similar to the attack of a snake. Before the attack, the snake is relaxed and fluid then suddenly gets tense during its attack, then come back relax immediately after.

Both Chinkuchi and Muchimi should work together

As we saw, Chinkuchi as it relates to helping generate the wave-like feeling of muchimi refers more to the sudden contraction and relaxation of muscles to help transfer momentum in a chained succession through the joints of the body into a technique.

Thanks to the combined power of Chinkuchi and Muchimi, I've seen Okinawan masters, I mean elderly gentlemen hit like a truck! They can generate a crazy, out of this world amount of power in their punch and strikes in general. By mastering these two Okinawan Karate power principles, you will also develop awesome power in your Karate punches. I have no doubt that if it can work for them, it can work for you!

The principles of power

Now that we studied what power is, it's time to delve into the basic principles of power. If you ask any scientist what is the formula for delivering a powerful punch, they will definitely answer your question with this simple, yet important formula: F= MxA.

That's, in fact, Isaac Newton's second law of motion, and it means that Force equals Mass multiplied by Acceleration. What does that mean? Well, basically it means that the heavier and the faster you are, the harder you'll hit. Pretty simple right? Simple to understand, but difficult to master.

1. Mass

Before training to improve your speed or acceleration, you want to improve your mass. More mass equals more potential punching power. But what does it mean to improve mass? Does it mean that you'll have to turn yourself into a Sumo wrestler and eat 20,000 calories per day? Yes! Now go to Wendy's and eat like there's no tomorrow!

Just kidding! When I say that I want you to improve mass, I don't mean that you should actually gain weight. Instead, I want you to use your mass more adequately. I want you to increase the amount of mass you can transfer into the opponent when you punch. But how do you do such a thing?

In order to do this, you need to execute every technique with the proper biomechanics or proper use of your body during a strike. That way, you'll put much more body weight into your punch, and you'll be able to generate an insane amount of power into your attack.

Being able to use your entire body weight into your punch, or any other strike for that matter will require a lot to time, training and dedication. We'll see how it's done a little further into this article.

2. Acceleration

Now that you understand the purpose of putting body mass into your Karate punch, it's time to talk about acceleration. Many people believe speed to be the same as acceleration. It's not.

Speed is the distance covered by a moving object per unit of time, it's simply how fast an object is moving. Acceleration, on the other hand, is the rate of change of speed, specifically its velocity. In other words, it not about how fast you hit, it's about how quickly you increase the speed of your mass, in the shortest time possible. In order to achieve tremendous speed in your punch, your body needs to be relaxed and supple. Remember muchimi?

A matter of progression

As your goal is to increase the power of your Karate punch, you should first start by developing the proper body mechanics to improve your mass. Making sure you are using the proper form or execution of a technique is the basis in generating power. After that, it will be necessary to work on improving your acceleration.

You should not focus on developing your Ki too early in your practice, dedicate your time on improving biomechanics and acceleration first. You should start to work on developing internal energy around 4th dan, after you have acquired the basics and applications of Karate and developed excellent biomechanic skills.
