Double leg root vs single leg root

Whenever you apply a technique that only requires one leg to be rooted to the ground applying/supplying power, that would be single leg root. But double leg root is more than 1 magnitude in difficulty. Single leg root merely makes a stick, rigid, out of the leg, hip, shoulder, and arm(s). Double leg root powered techniques and methods use twice as many components, and also combine them together in a number of interesting mixtures.

The single root power source seems very simple. As one example, if someone pushes you in the chest or arms, you can take that energy and send it straight to your hip joint and then transfer it to the leg and into the ground. So that him pushing you is about the same as him pushing down on the earth where you stand. In order to move you, he has to uproot you or use enough power to move the earth itself.

Let’s look at a double leg power source. This is why Taiji Chuan was often seen as magic. When a person pushes you on the left shoulder, you can take that energy and shoot it down to your left hip joint connected strongly and rigidly to your left leg. You now have a line resisting his force incoming. However, you then split off part of that force vector coming from your shoulder and send the other part to your right hip joint. Your right hip joint then sends it to the ground via your right leg, and it then goes “back up”. It goes back up to your dantien, or lower spine/gut/middle of your hip joints. At this point, your left hip joint is being locked in place by two power vectors (one coming from the enemy and one coming from the ground up). Because the hip joint locked that way and can’t flex, the power from the right hip joint that has been reflected back can only go somewhere else, either the left shoulder or the right shoulder through the torso/spine column. If it shoots up to the right shoulder, you now have a power source supplying your right hand that is equal to or greater than the force the enemy is using on you. In this fashion, it can be said that when an enemy strikes you, you are merely using his power reflected back to attack. With the utilization of mechanical advantage (levers) and force multipliers (gravity, momentum, centrifugal force), the outputted force can actually be several “times” greater than the initial source.

In the sense that internal arts value structure more than speed or strength, this is why. Without the right structure and alignment, the human body cannot manipulate forces in this manner. It would just dissipate as your joints bend and flex. The right structure, however, is never the same. It always changes based upon the context, which is why it is rather complicated and for military purposes violates the KISS rule. Taiji Chuan can thus be considered more of a strategic or logistical tool than a tactical weapon.

Things like this make a lot more sense if people who do a lot of striking understand how force issues from their hand and how force reflects back into their hand when hitting a target.

As it turned out, the techniques don’t matter compared to the foundation and the power source. For example, it doesn’t matter what I use a generator for, all that matters is that the generator works and has fuel. If that is so, then I can use it for any number of things. I don’t need to specify a single limited use first.

For soldiers, this knowledge can be adapted to help spread out load distribution. It can help absorb recoil from rapid fire weapons while maintaining a running, prone, or kneeling position. It can provide better bio physical stances that avoid injuries to the knee, given the weight of modern battle kit and armor. A good idea never has “one” use only. A good tool is never limited to doing one thing. When a modern soldier in double plated kevlar and fully kitted out is fighting in urban terrain, it’s probably a bad thing if someone rushes in close and gets into tackle range. If the soldier falls, he will have a difficult time fighting at his preferred range with his preferred weapons. However, if people trying to ram you just bounce off as if they hit a solid wall of concrete, maneuverability and distance control is maintained. Allowing for more efficient termination of objectives.

For a warrior, they utilize the knowledge slightly differently, but for similar purposes.

    hey man, I have came across this quote written by you:

    “And why is it somehow more intellectually chic to believe in aliens than in God?”

    Because they don’t want to think about aliens wiping out their little planet.

    They like to believe God, is the primary threat. As if their little mortal pathetic limbs could reach out against God. But it makes them feel good. Powerful. Powerful enough to deal with aliens as equals. As if.


    I just want to say that this is soooo TRUE.
