I uploaded a new video to YouTube.
Here is the description of the video:
An exercise to show why we work on push tests. We typically work on push tests to outstretched arms, to shoulders, and to chest. In this video, I wanted to show a progression from a push test to a technique to show or illustrate the applied internal skill.
In this example, I'm working with a medium level push. My partner isn't trying to bowl me over, but he's giving me a decent amount of energy in the push.
First I move away quickly to show that my partner is pushing and not just standing there. Then I let him disengage quickly to show that I'm not pushing back into him.
Finally, while he is pushing, I turn 90 degrees towards him and then apply a simple nikkyo lock. This shows that I am working on internal structure to receive the energy of the push and not give up my center, structure, or balance. If I can use internal skills to, in essence, be unhindered by whatever energy or attack my partner provides, then I am free to move as I wish.
If I can accomplish that, I'm not forced to "physically move" my body to gain kuzushi or to capture my partner's center or to destabilize his structure.
Again, this is a simple example and isn't meant to show any kind of dynamic engagement. However, at a certain level, one can use internal skills in a dynamic manner under freestyle environments.
