Well, another reason to talk about it at this level is that this is the more visually observable use of qi/ki skills. You can see it on youtube and then discuss it. So you're smart to stick with this type of skill.
For me, the qi work is more about sensitivity than peng, so you and I may disagree a bit about that. But sensitivity is something that has to be felt; it can't be seen. So it's pointless to discuss it usually.
As to people already having it, I would be surprised to see this type of movement in mainstream dojos.
Having said that, i have been taught many IMA-like things in my judo class here in Taipei. But I'm noticing that my judo teachers don't have the detailed vocabulary to describe the movement that you would get from a taijiquan, baguazhang, etc. teacher. The 7th dans in my club do all have IMA abilities but they seem hampered in teaching it by things like the sport environment, vocab, etc.
Just some thoughts.
Hi Dave, thanks for the contribution.
I think the video is nice as it gives people some observable "take-home" points to work with or at least think about. Yes, it is basic stuff. I think in Judo we practise it under tai-sabaki or just, as Hanon sensei pointed out, shizenhontai. (I would be very interested if this is related to Kito-ryu's tai and hontai and especially if C.K. sensei would come along and tell us more.)
I disagree with the gentleman in the video that this stuff he showed is different to what is in Karate. Efficient body mechanics, through use of the body frame and what is described as "ground path", is from what I understand an important part of Karate (or at least what I know as Goju-ryu Karate-do). Now, whether the Karate that a typical person in the West can have access to and observe is of a sufficient level to demonstrate those skills is another issue.
Yes, I too think it's smart to have the skill of efficient body mechanics, no matter the martial discipline, sport or any physical movement e.g. carrying bricks and butchering. However, Dave, I disagree with your point that, in the context of Taijiquan, qi is about sensitivity. I also disagree that qi is all about 掤 peng. (This is despite that qi can be associated with peng. Peng can be performed with the skillful use of qi, but that is not necessary.)
To figure out what the term qi means in Taijiquan, or come up with plausible theories thereof, one should refer to the classical Chinese literature. The difficulty lies in that the same characters may mean very different things depending on context. For example, I'm sure in your study of Chinese martial arts, Dave, you must have come across 天地人 (heaven/sky, earth, human). I'm not sure what meanings you've learned about the three characters in Chinese martial arts, but they can also mean:
1. Large dimension/space; small dimension/space; and even smaller dimension/space, such as the human body.
2. Positivity; negativity; and zero.
3. Variables in old Chinese algebra, similar to the xyz in our modern algebra.
4. Timing 天時; geography or resources 地利; and social or personal interactions 人和.
(Do not think that these usages of the three characters have nothing to do with Chinese martial arts. In fact, the first two are highly relevant to Chinese internal martial arts.)
I seem to have digressed, but I wanted to use an example that is not so controversial. My point is that when we look at certain technical usage of Chinese characters, we have to understand that:
1. It is contextual.
2. It may be based on pre-existing theories or principles.
3. It is for some purpose, like mathematics, medicine and biomechanics.
4. It can change over time.
5. It can be different due to geographical, demographical or (sub)cultural factors.
6. Two people may hold different views, even if in the same context, same time and same place and for the same purpose. They may both be experts in the field.
7. Differences in meaning of a character can exist even within the same text and in some cases the same sentence! (e.g. 道可道非常道)
So what can we do? Study the literature, its sources and other kinds of evidence. Learn the history and the prevailing paradigm at that time. Learn about the people. Learn why did they write and use the literature. Then come up with a plausible interpretation. Hopefully that interpretation will work for you. Perhaps we can test it, using modern scientific theories, principles and methods. It's not easy. It's not an exact science. Sometimes you cannot get a perfect answer. Nevertheless practitioners of disciplines need something to work with, so usually one has to settle for the most plausible interpretation one can come up with.
Back to the character 氣 qi, I refer to the 精氣神 (jing, qi, shen) concept that is in 易學 (yi xue, the study of changes). The concept of jing/qi/shen that has been prevalent in certain fields in ancient China such as medicine was used to explain how does the body work, which was an important part of martial disciplines such as Taijiquan.
What exactly are jing, qi and shen? I have come across a theory, which I will try to explain below. Jing, qi and shen are related, or parts of, our body.
天有三寶日月星,人有三寶精氣神。
(The sky/heaven has three treasures - sun, moon and stars. The human has three treasures - jing, qi and shen.)
The character 精 jing consists of three characters 米 (rice), 生 (life) and 月 (moon, but this character is associated with 肉, meat). 精 jing refers to the physical substance of the the body, formed by what you eat like rice and meat. The tangible stuff - muscles, bones, tendons, ligaments, etc. - the solid substances.
Now everyone is interested in the character 氣 qi. The very first way to write or draw this character is like this:

website, which interestingly has another explanation of the character.)
The three squiggly lines suggest that the thing called qi is fluid and perhaps also gaseous. Why gaseous and not liquid? The lines being not parallel implies that what is depicted is not the flow of liquid. Contrast that with the old form of the character 川 meaning river, showing the flow of water with parallel lines:

Referring to gaseous substances is also a common, everyday use of of the character qi in modern Chinese, as in 空氣 air, 大氣層 atmosphere, 吸氣 inhale, 呼氣 exhale, 閉氣 hold one's breath, 蒸氣 steam, 氧氣 oxygen, etc.
For now, let's just stay away from interpreting 氣 qi as energy. I'm not saying that's wrong, but under this current theory of 精氣神 that I'm trying to explain, qi is referring to just some kind of gas. That is, mainly speaking, the air we exhale and inhale with our lungs.
So we have 精 jing the solid of the body, the flesh, and 氣 qi the gas, the air we breathe. That leaves the liquid part, 神 shen. NBK and I have discussed this before - shen can mean tens of things in Chinese and also Japanese. 神 shen even in modern Chinese is usually used to refer to intangible things such as god(s) and consciousness. However, again we are limiting our interpretation to the current theoretical framework. There are different types of liquid substances in our body. For now let's limit 神 to mainly mean blood.
Here we have classified the substances of the body into solid, gas and liquid. So, our body is a system of flesh filled with blood, with a cavity inside that can hold air. The talk about body structure, "ground path", body frame, etc., is all about the solid stuff. The movements still mainly rely on skeletal muscles, even though the use of which can be very efficient, like using the right muscle groups/fibres at the right time for the right purposes.
In Taijiquan, one should at some stage learn about using the air and blood too. The part about using the air may be quite familiar to a lot of people, in the form of things like kiai and breathing control. What is special in Taijiquan is one system to use all of 精氣神 jing/qi/shen at once.
It is about making your body become a hydraulic machine. Through manipulation of the condition in the lungs, like inhaling/exhaling and holding/releasing your breath to control the volume of air in the lungs and using the diaphragm and movements of the torso and limbs to control the pressure, the body's pressure and flow of blood can be controlled. It is with this skillful use of blood pressure and flow that the Taijiquan practitioner can general force with the body without contracting skeletal muscles. This, in the context of Taijiquan, is what I called the skillful use of qi.
This qi is not exactly intent. It is physical. Of course, what goes on in your mind and the rest of the nervous system to control your body to achieve that is important. However, the above 精氣神 framework in Taijiquan does not need to go into that aspect.
The above theory is currently the most plausible that I have come across on 精氣神 and the use thereof. Note that I have yet to study more about it.
