In terms of power, the arms are more or less insignificant. A screw is driven into wood with a tool to transmit torque – a screwdriver. In an ideal (taiji) system Energy_in = Energy_out, but in reality it’s Energy_in = Energy_transmitted – Energy_lost(friction, aim/structure, material…). We want to minimize the losses as much as possible to come as close as possible to the ideal case. Since a screwdriver is one solid piece, the loss is proportional to the ability of the user to keep the driver straight while applying constant pressure to the screw and rotating the handle i.e. the wobble or ‘concentricity’ of the applied torque vector with the CL axis of the screw. This is why imagining a target further away than your immediate target is recommended for accuracy. Geometrically you are narrowing your range of losses. Mathematically you are increasing your probability to
2. Apply enough perpendicular force to screw to keep full contact between screw socket and driver bit
3. Rotate driver –> screw travels axially
Repeating steps 1-3 incrementally moves the screw along it’s longitudinal axis of. Notice each step involves one action to move the screw on it’s intended course. Although each action is discrete, they are superimposed and not combined – a cardinal mistake on several fronts. If you read the above steps as a machine would (1’s and 0’s), the screw would travel straight and true every single time. For whatever reason most of us however read the steps and (sub)consciously add\remove others. Keep in mind a screw has only one function as far as it’s concerned (to penetrate) and only one method (spiral). If you made an honest comparison between what you are supposed to do and what you actually did, it’s safe to say they will never be the same. Hence the results will never be the same. But the importance lies in your intention: trusting the definition of the result and it’s method.
Now assume your arm is a screw and every other body part behind it is the driver. Revisiting the screwdriver analogy we have the classic 1-2-3:
1. Establish intentional spatial point A — (contact)
2. Maintain constant contact aimed at point A — (lock)
3. Rotate (drive) point B to drive point A
Naturally when this sequence is iterated, the last point (B) would be in contact with the ground. Mechanically the body can then be seen as a transmission vessel much more complex than any other man-made mechanical transmission since every part of the body is connected and has the potential for multiple degrees of freedom. A simple ‘discretization’ of this analog of 1-2-3 would be to split the body at a shoulder so you end up with two pieces: one arm and everything else. 1-2-3 becomes
- Place arm
- Lock arm
- Drive arm with everything else
With sincere practice you will find bigger means more restriction since your body is not tuned to the increased . It is important to not move past the point where you physically a limit of . You know you have reached this point when you sacrifice your fixed point e.g. shoulder pops up. One benefit of going low as a beginner is to help prevent your kua from moving side to side. All the tension created helps stabilize the kua in preventing it from collapse. If you always practice in a comfortable high position, it is much easier to collapse the kua.
Resolve the action,your spot. If you can stay steady, no up or down, you are working your ability for holding a spot.
- Squat with one leg out
Bottom should be 1″ from the ground
Forward bent knee should be 2″ from the ground
Front toes pointing up
- Bounce stretch. This gets brain more comfortable with going lower. Stretching is all mental; you have to get the brain to allow the body to relax.
- Step out wide 45-degrees with toes up
- Plant foot
- Grip the ground with toes while placing the knee over the foot
- Lock the knee over the foot forcibly by placing both hands on top of knee and pushing perpendicular to the ground
- Bring back foot up without any movement or wobble of the front knee or upper body. This is where you practice “sucking” the trailing leg.
Practice the splits and sucking everyday for a few minutes each. The goal is not in how much you do each day, but how often you keep it up i.e. consistency. These will stretch and strengthen your internals, most notably the tendon/muscle running down your interior(gracilis)?
