[QUOTE=Alan Orr;736843]Hi couch
It is correct to use K1. The heels lack control of power when you receive force.
You may use the whole foot at times when loading weight, but to issue forward pressure you must transfer weight from the whole foot to K1.
This is from one of my articles:
Ging Chong Gwut Gun Faat, Lik Chong Gerk Jang Sheng - Power comes from bones and tendons, strength originates from the heels
Often people describe power in Wing Chun being delivered by bone power or bone alignment. Unfortunately, what you often see is locking out of the joints, i.e. the main punching arm will be extended at the elbow and shoulder. This is a very limited source of power development and more importantly causes severe damage in the long term to the elbow and to the rotor-cuff of the shoulder. (As a practitioner of Chinese medicine, I can confirm that I have often had to treat this problem with new students). Now, locking the joints out on impact does produce a release of power but this is only a small amount compared to the power that can be produced with the whole body structure via kinetic linking to the ground. One of the main benefits of this type of body connection alignment is that not only can you issue power in this manner due to the “spring” nature of the body but you can also absorb power through the body into the ground without taking undue pressure into the joints. If you align your body in this correct manner the joints will absorb pressure and redirect the pressure without effort into the ground and the tendons will twist and strengthen and become stronger with this practice. Therefore when we talk about strength originating from the heels this is really talking about absorbing pressure and rooting therefore explaining the nature of the body in its spring position.
“Power originates from the heels, travels up the ankle and knee joints, is in conjunction with the waist, issues forth from the body and rib cage, travels down the shoulders, to the elbow, to the wrist and manifests from the hands”. -Robert Chu Sigung
Let me sort out the missing links for you. Kinetic linking is a term which describes how to correctly load gravitational forces in your body.
Generating maximum mass is achieved through the alignment of the ankle, knee, hip, shoulder and elbow. These are the kinetic links in which power is generated and transferred. Should one of these links be out of alignment, its ability to transfer power from the rest of the body is reduced. To issue power using these mechanics you push your body forward and upward, making sure the three dan tian are moving in sequence, from bottom to top (Qi Hai > Tan Zhong > Yin Tang). Your three dan tian points are located approximately at the same positions as your segmented centers of gravity. So what you’re doing is pushing your entire mass forward and upward using all the aligned kinetic links (joints) in your body. Whether stepping or stationary, the principles remain the same. This is what is meant by using power from the ground up. Naturally, rooting power into the ground is done using the same mechanics.
The problem you will have in combat if you are locking out your joints is that you have committed your striking power. Therefore if you have actually missed your target you will find yourself exposed and also will have no stored power available. When I think of this I would say it is like having only one arrow, once you’ve shot that arrow you’ll have none left. If you generate your power from the ground you’ll have an endless source of ammunition. So now you have an automatic machine-gun! Therefore if you punch and miss you can then readjust and re-fire much more quickly and much more effectively because you haven’t over-committed your arm position. The fact is, the body alignment and body position are the important factors in generating power.

Thanks for sharing, Alan. Can you please explain to me how YOU teach someone to shift on this point? Do you instruct people to shift initially like the LT guys do it (one foot at a time) and then together, etc? Just playing around with this shift.
