Class 15 - Hidden hand punch L&R



Before you go on to the next class, please allow yourself for at least:
Suggested Hours: 3, Suggested days: 3.

Class Introduction

The punch part is replaced by a long push without explicitly issuing power. By Practicing this way you can emphasize more on the waist rotation and legs' coordination, rather than the power of punch itself. Once the coordination has been built, the entire muscle group from feet up to torso, to arms can be motivated simultaneously.

Instruction Level: Dynamic

The whole body movement need to separate into two parts, the stretching half and the pulling side. The stretching side: 1/ put palm on the side of waist. 2/ sit back to rear foot, get hip, shoulder, elbow and wrist connected. 3/ torso sift weight to front hip joint, arm straighten 90%. The source of straighten is from ankle, knee, hip, shoulder elbow to palm. The pulling side: 1/ At the end of the previous palm, turn torso 90 degree and shift weight to the rear foot. This turn will drag the arm across and path a curve in front of you. The arm is about 60% extend. 2/ At the end of this turn, slightly turn backward(10 degree), reach out arm to 95%. and shift weight 20% back to the other foot. This is to prepare for pulling back. Preserve the energy. 3/ Shift weight entirely into front hip joint. Pull arm back to the side if waist. This is also including a slightly pressing downward.

Instruction Level: Dynamic

You can observe the relation between the chest cage's rotation along with arm's movement very clear in this view. Notice that the rotation of the chest cage is developed from waist. But what is the source of waist rotation?

Instruction Level: Dynamic

Yes, to answer the previous question, what is the source of waist rotation? The legs. See how to arrange the hip joint's orientation so that the related foot and hip's angle vary. This variation makes one leg in good position for supporting weight and the other leg can generate the push. While the vector of this push always eccentric from the center of gravity [CG]. The product of the leg push and the distance between hip joint to CG (Dan Tein) equal to the torque generated.

Instruction Level: Static

From this view there are two points we can observe: 1/ Just before the right palm extending, you shift back your weight and turn torso to the right side about 10 degree. This turn brings the right elbow and shoulder from a little circle with it. Simultaneously, right palm and foot integrated. 2/ When the left arm stretching, weight shift to the right foot. Notice how your right arm pulls back and press down to stabilize the movement.

Instruction Level: Intention

If there is a string tight between your palm and a point extend from the direction of your forearm but 100 feet away. How to use your torso rotation to lengthen this string? When arm pushing forward, imaging the string is tighten far away from your back. You are pushing the end of this string away from the other end to lengthen it. You should use only the torso rotation. Therefore, your elbow and shoulder angles should maintain almost constant. Can you do it correctly?
