Force = [ (Mass x Acceleration) - Fallacies ]

I tire of hearing this equation bandied about by people using it to talk about power.

It's not that the equation is irrelevant to the generation of power. The problem is that the equation is regularly abused by people using it to promote their own pet concepts, or to seem more clever than they are.

Whatever you think of power, the true worth of a practitioner is measured by his understanding of risk and reward. Meaning all the skills that help him cover against strikes or block them coming his way need to always be present. Next is the tactical understanding that the closest distance between your tool and the intended target is a straight line. Pull your tool back and chamber for more power, and you might find yourself on the ground nursing a black eye.

The two factors that help you generate Force - which is what martial artists are interested in are the interplay of mass and acceleration. In a discussion recently I stated that a practitioner will find his upper limit of speed and acceleration rather quickly. What I mean by that is that with a little training and maintenance, most people will achieve the maximum they can ever achieve in a short amount of time. How much fast twitch muscle fibre you have is how much you'll have. If you're genetically gifted, that's great ... but it'll take a huge amount of additional effort to eke out very marginal gains after you first get it.

Mass however is a very different part of the equation, and this is where I find myself having the most contention with some colleagues. Jesse Enkempe in How to Get Massive Power in Your Karate Punches hit the nail on the head when he said "If you are a beginner ... the only mass you'll be able to move into the target is basically your hand. If you train a little longer, you might finally get the whole arm behind the punch. That's a few more pounds! And if you train even more ... you might finally get your whole body's mass behind the punch."

The trick is not attempting to put on mass by waiting for the effects of resistance training or by going to Macca's. And the fallacy of thinking is that everyone's mass is the same. Your mass might be the same if you're standing still, but I can assure you that an untrained person cannot shift his mass as effectively as I can. Simply put, I can accelerate and decelerate more of my mass to support a wide range of striking tools.

In the post Creating a New Upper Limit to Your Punching Power, I talk about creating more mass using compound muscles to drive the strike. The body structure supports both the initial acceleration, and the final deceleration. This closed system type of process helps transmit mass into the point of impact. This is the secret to striking with the body as one.

This contrasts heavily with people trying to throw their strike as a flail into the target. This is a haphazard motion - which while capable of generating force is not generating force effectively. Meaning you will need a strong person to strike the target strongly. With the traditional punch as I described above, a smaller person will have a new found upper limit to punching power that will simply be astounding.

I urge you to re-examine these concepts. After thirty years in the martial arts, this insight gives me cause to return to much of my previous assumptions, and in discussions with other people who have experienced similar gains, we agree that everything is 'the same, yet different' - just through this new insight.

And this new insight directly affects my ability to generate a huge amount of power. Against other respected and experienced instructors, I have used simple strikes whilst they hold strike mitts, and the bruising which occurs as the power blitzes through the target is serious. I have literally had instructors complain about their bruises without mentioning that there was a target that existed between their body and my fist.

I'm not saying this to boast. I am saying that with what feels like minimal effort on my part, the power generated is so frightening that all martial artists should explore this training in order to fully appreciate the value of traditional training.

Keep safe.

Dan-gun: Twin Outer Forearm Block as Uppercut (Step 9 & 11)

Twin Outer Forearm Block - a dead ringer

An uppercut is an excellent versatile strike that comes from underneath, between arms and can find a target in tight situations where a straight punch might not land. It's a fairly easy strike - so there is absolutely no logical reason why I should wait until Kwang-gae Step 2 & 3 to learn an 'upset' punch which is more or less related to the uppercut, but which strikes towards the body not upwards toward the head.

Kwang-gae's Upset Punch - a Little Too Late?
Uppercuts are done close range, with body torque allowing you to find holes through the opponent's defences in order for the punch to land. Entering close range means to put frontal pressure on the opponent using gap closing tactics.

Most cross-training nowadays will help you achieve a decent punch. Hand mitts are held facing downward and toward you and you strike upward. To improve on the strike you should try not to let the arm move freely from the shoulder, but to support the striking motion with body torque and leg expansion.

The Twin Outer Forearm block done as strike is not a boxing tactic. The raised arm is there as a cover and as a grab-control. If the person punches you and you attempt to do this, your opponent will retract his arm and you will be dragged forward AND your strike will be unsuccessful. If you however attempt to strike the opponent with your back hand, the opponent will seek to block or jam your strike. When he does this then you punch under his arm toward his head.

The back hand indicates that you should explore ways to control an extended arm - this does not mean the opponent will give you his arm willingly.

The turn of pattern Dan-gun indicates that you are best using this tactic when you approach the opponent from the side - rather than front on.
