His demo of beng wouldn't match up to a rip to the ribs by Tyson
When he pushes the guy back he uses two totally different directions of force
Apples and oranges

wayne hansen wrote:Language is language
I look at the physical language
Tyson or no Tyson what he is showing on how beng works is not internal just bad mechanics

and rational...noting the same explanations are used and demoed among other
teachers talking about the same things.

I would question some of the assumptions made, as to distancing, and combinations ect. noting in some of the very public fails shown by those claiming to be practitioners of taiji and wing chun exemplify some of the ideas suggested in the clip.

guess you missed my earlier post.

What he mentions and assumptions made, can be seen if one looks at the public fails of those who've said they were practincers of the arts mentioned.
It might one of the problems in their training found out the hard way...

While at other times working with others under certain constraints
it may seem to work...

The mechanics of fajin His take on the "differences"

Thought the "demo" was ok, for some of the points it was trying to make.....

Jia-Hao Chang, Yao-Ting Chang, Chen-Fu Huang on 16 September 2014 wrote:The ground reaction force helps create maximal power in a short duration, allowing a maximal impulse to be instantly transmitted to another party. Body-wide muscle coordination occurs during transmission of the ground reaction force and is a key contributor to the quality of fajin movements [2]. When the fajin is released from the body, all of the joints in the upper and lower limbs shift from flexion to extension. Large joints, including the hip of the pushing foot and the shoulder joints, start extending once contact occurs. The shoulder joints continue extending throughout the action period. In the lower limbs, joint exten¬sion begins with the rear pushing foot and extends to the front supporting foot, whereas in the upper limbs, joint extension occurs in a bottom-up man¬ner throughout the fajin motion [3]. The movements of the limb segments and joints are mainly produced by muscle contraction, which is activated by nerve potential that are conducted to the muscle fibers. The speed and tension of the muscle contractions corre¬spond to these nerve potentials. …

This sequence of peak activations is identical to the order determined by Nien for all of the examined muscles (except for the triceps) [1]. The integrated muscle use involves pushing by the rear foot, extension of the rear leg to maintain stability, and continued force exertion through the upper limbs. The force in the upper limbs prevents the reaction force (generated by contact with the fajin recipient) from bending the upper limb and mitigates the forward thrust of the fajin motion. The muscle groups in the torso are responsible for main¬taining the upper body’s postural stability to avoid a loss of balance. The muscle groups in the right sup¬porting leg reach their peak activation during the late stages of fajin, providing stability as the center of grav¬ity shifts forward into a lunge. This movement helps complete the power transfer process.
