first beyond the fak feed he is also doing as Joy noted
The feed is intentional, because they are working together, not fighting, as explained, and as you already acknowledged, it "
does a worthy job of checking on the wu".
Joy said; "
targets the bong sao of the other guy with a punch aimed at the ceiling".
On the punch side of this drill, the focus is on coordination of
jat+punch, and full body power through the hip and elbow connection behind the punch, hence you see the low elbow driving forward. Focus on the hand, and you miss the important bit. Look for the elbow and hip.
This drill is not trying to actually punch and block each other in another versus match off.
The punch and the
bong serve cooperatively as reference points for the partners to train correct hip and elbow drive for the punch and elbow rotation for the
bong, and to get the necessary repetition in to condition these behaviors.
That said, the punch is aimed at the chin, and would continue to hit there if the
bong wasn't present, as the instructor checks for several times.
Again, if you are thinking "versus", actually trying to hit and force blocks, and looking at the hand, you're missing all the important development of mechanics. This drill is not time for fighting each other or training this vs that applications.
Many actions in VT training are uncompleted because the focus is on developing certain aspects of the full action. If you don't understand the abstract nature of the training system, you will be looking at it all wrong and change things that shouldn't be changed, losing the entire benefit of the training in exchange for applications.
Have another look and focus on the hip and elbow, not the hand and trying to actually hit the other guy in the face.
Next he applies his own lap at time with an elbow bent at almost 90 degrees and at times in line with his opposite shoulder.
Wu is supposed to be offset behind the
bong. It can't be extended much further without sending it out to block along with your own
bong forearm like a shield as you do in TWC.
This is not preferable to us because it is committing two arms against one and losing your next hit position so you have to do another move to clear before striking, since your
wu cannot punch.
