Greetings all,
BBT and DP, nice links and commentary on the Yang family doing some pulls!
I would like to make some additional comments about the original post. Like a number of styles, we have a number of doctrines that overlap in meaning and usage. I think it is best sometimes to make sure not to mix them.
The first of particular relevance to the OP is Five Element theory applied to the lower body. Our basic idea is that the legwork in a stance should be balanced in all directions. In this case, to make it simple, Advancing Footwork (进步 jinbu) should be balanced with Retreating Footwork (退步tuibu) to leave you “Established in the Center” (中定zhongding).
“Rooting” is a separate doctrine that is most driven by relaxation in the legs.
“Sinking qi” is another doctrine driven externally by body shape and internally by the mind and breathing. This connects with rooting in many places, but perhaps most obviously externally in keeping the lower back/waist loosened/relaxed (松腰song yao) and the tailbone centered and aligned (中正zhongzheng).
Our stepping method is another doctrine which involves:
1. “Stepping Like a Cat,” or stepping in an agile precise way (heel, to ball, to toe and bend knee)
2. “Walking on Thin Ice,” or placing the moving foot lightly and shifting weight smoothly
3. “Walking through Mud,” or not lifting the feet too high as if trying not to splash mud on our pants
Our stance characteristics are another issue. In our typical bow stance, we have a forward lean that can leave the back leg and the back in one straight line. The back leg is naturally straight, but not locked. The weight distribution is 60%-40%. The weight must be in the Bubbling Wellspring of both feet. The crotch must be rounded with the knees in line with the toes of the respective feet. The front knee should not bend beyond the toes. The tailbone must be centered and aligned (中正zhongzheng).
The last doctrine is that you should generally not meet force with force and should use softness to overcome hardness.
Some practitioners train back-leg sinking by letting their partner push on them while the other sinks continuously, but I have not seen the overt training of front-leg sinking. It was nice to hear fchai's response that they are mindful of front-leg sinking in the form and therefore why not as a training exercise as well?
Since our form frequently trains a bow stance with a lean, I find it beneficial to do stance testing against a pull in the direction of the front toes. Often I find people, even with substantial experience, who do not perform well. I think this is because they have not really gone beyond the simple instruction to avoid bending the front knee beyond the toes. In my opinion, this simple guide is insufficient and even becomes irrelevant if the other stance aspects are observed and understood.
To do the stance correctly, I think it is important to understand the thrusting (蹬deng) role of one leg and the supporting (撑 cheng) role of the other leg. In a final stance, these roles become latent, but are still arguably aspects of the underlying equilibrium. Many people just rest on the ground like a chair and do not feel the "motion" of the energy in the stillness.
When I assume a bow stance and just lift my front leg and change nothing else, I automatically leap slightly forward (and then bring up my back leg to resume the same bow stance). I “leap,” not because I send a command to my legs to do so, but rather because that energy is already there and merely manifests itself when no longer balanced against the supporting energy of the front leg. It is the same principle when lifting my back leg, except in the opposite direction. The components of the already existing equilibrium become manifest.
If you feel this energy in your legs, it becomes increasingly obvious to your feeling why you have to have weight in the bubbling wellspring of both legs. Many people do not maintain the feeling in the back leg and just let it rest on the ground, like the legs of a chair. To maintain the feeling, you have to “round the crotch,” keep the knees in line with the toes, keep the tailbone centered and aligned, and loosen and open up the lower back. Above all, you need to maintain a feeling of looseness and relaxation in the legs to allow the tendons to communicate with each other and form a flexible unit. I actually feel the bubble wellspring of both legs actually pressing into the ground, almost like my stance is squeezing in between the contacts with the ground.
If you have fulfilled these conditions and someone begins to pull you forward during stance testing, you do not have the feeling of needing to initiate countermeasures or setting up a pivot point in the front foot with a dead back leg. Instead, you have the feeling of adjusting a lower leg relationship that is already active and present. Your tendons just automatically adjust. More pulling force feels like it wants to pull the entire structure forward, like a car breaking suddenly. Maybe you might “skid” a little bit, but the car has no tendency to flip over or lose control.
If we are not talking but stance testing, but rather about true counters to a pull, then we must consider “not meeting force with force.” This is our general, but not universal rule. I can think of four or five general category of tactics that we use to observe this rule, but also a few we use as seeming exceptions. Those are my personal thoughts, based on what I have been taught. I can perform counters corresponding to most of the tactics, at least in semi-controlled circumstances. These are best experienced during our practice of counters, rather than intellectually through discussion and reading.
Take care,
Audi
