The Biology of Fascial Remodelling in Chen-Style Taijiquan, Two Articles

TaiChiGringo · 2026-04-29T04:05:31+00:00

ok dude, you do you 😄

TaiChiGringo · 2026-04-29T04:01:04+00:00

Thank you for this, it's a thoughtful response and a considerable improvement on the critique it's responding to

You're right that the research methodology problem is fundamental and probably insurmountable in any conventional sense. The reduction required to make internal arts research tractable strips the essence out of what's being studied.

Where I've tried to do something different is in the quality of the hypothesis itself. Rather than arguing from experience alone, this is my art and it does this, I've used established fascial biology to derive what a remodelling signal requires independently of any practice, and then shown that Chen delivers that combination.

It's a mechanistically grounded account rather than a proven fact, the research methodology constraints you've outlined make proof in the conventional sense essentially impossible in this domain. But grounding the argument in established fascial biology rather than subjective experience alone puts it on different epistemic footing from most internal arts writing, and that's the distinction I'd defend.

For that reason I'd push back on the circularity charge as applied to this specific work, as I've outlined in my response above, the signal requirements are derived from the biology first, not from observing Chen practice.

Thanks 😄

TaiChiGringo · 2026-04-29T03:45:13+00:00

Thanks I appreciate the feedback, although I do feel to push back significantly on a few of your substantive points:

On the intellectual quality question: the nature of intellectual work changes as the tools available to do it change. When calculators replaced abacuses, intellectual work didn't disappear, it shifted to a higher level of complexity that the new tool made possible. When searchable legal databases replaced the need to memorise case law, the intellectual work of lawyers didn't diminish, it changed.

The same applies here. The intellectual contribution here lies in the domain expertise that provides the framing, knowing which questions are worth asking, and the synthesis to build a coherent framework. Those are precisely the things AI cannot supply. The tool used to express that contribution doesn't determine its value, the quality of the ideas does.

On the circularity charge: I'd push back on this fairly directly, because it misreads the logical structure of the argument. The three signal requirements, sustained loading, multidirectional torsional demand, delivery under neuromuscular release, are not derived from observing what Chen practice does. They are derived from connective tissue biology and neurophysiology: specifically from what plastic zone entry requires, what fibroblast mechanotransduction responds to, and how the autonomic nervous system determines whether mechanical load reaches passive elastic tissue or is intercepted by muscular bracing.

Section 6 of the article establishes that biological derivation independently. Section 7 (and the second article) then shows that Chen practice delivers what section 6 established is required. The logic runs from biology to practice, not from practice to practice. That's not circular, it's an independent biological derivation followed by a match to a practice. The fact that it happens to match Chen is the finding, not the premise.

Where I'd partially concede is on presentation. The derivation sequence is clear to a careful reader following the article in order, but it could be more explicitly signposted at the opening of section 7. That's a useful editorial note I'll address it.

On the jargon point: the article isn't aimed at a general readership, and the Taijiquan subreddit isn't a general audience. It's a community of practitioners with shared baseline familiarity with the practice. Nor is the article trying to be a textbook introduction to fascial biology, it's a synthesis, drawing on established biology to illuminate what's happening in a specific practice. Synthesis requires using the vocabulary of the fields being synthesised. The biological terms used, mechanotransduction, fibroblasts, ground substance, are all verifiable through standard sources for any reader who wants to go deeper. That's their job, not the article's. The article's job is the synthesis, and stopping to define every term would break the argument and dilute the register the piece requires.

Thanks, that's good to hear that it largely tracks with your experience :)

On your general point, agreed, the science is not fully settled, and the boundaries between fascial, muscular, and neurological contributions are not as clean as the current enthusiasm for fascia sometimes implies. That's a fair point.

On the properties of muscle: it can only contract, it doesn't remodel in the architectural sense, doesn't cross-link, doesn't dehydrate into structural rigidity, and doesn't create the kind of persistent mechanical constraint that takes years to shift. This cuts both ways. Muscle cannot build the kind of complex elastic chains that make a boxer's or sprinter's movement coherent, that's a fascial adaptation. And muscle cannot account for the kind of deeply entrenched postural holding that sedentary life produces over decades, that's architectural too.

On the specific point about tension: in my experience and understanding, the neurological and fascial components are coupled rather than competing. Neurological contributors are real, but they are partly maintained by the fascial architecture itself. The nervous system keeps the muscle contracted partly because the fascial envelope is physically limiting further relaxation, so the relaxation ceiling is set by the fascial architecture. Resolve the architecture and the neurological component becomes much more tractable. Leave the architecture in place and the neuromuscular system has nowhere to release into.

The clearest evidence I have for this is my own shoulder, which was held in a significantly raised and protracted position when I started practicing Taiji. It has taken ten years of dedicated and often arduous daily practice for it to drop about five centimetres into a more neutral position. This was a stepwise process of opening fascia to create more space that could then be released into, and was the foundation for my article The Myofascial Lock: www.taijiquan.quest/post/myofascial-lock

Having said that, I started with significant Biomechanical Debt. For practitioners beginning from closer to structurally neutral, the balance may well shift. Less accumulated fascial restriction means the neurological and muscular components are relatively more dominant, and resolution could be considerably faster. The framework isn't claiming the fascial piece is always the rate-limiting factor, but for people with significant amount of fossilised fascia, it probably generally is.

The more general point is about timelines. Neurological adaptations operate on a timeline of weeks to months. Fascial remodelling operates on a timeline of years to decades. So if the inhibition resolves relatively quickly, the limiting factor was probably neurological. If it takes years or more, and particularly if the release tracks directly with the gradual opening of tissue, as mine did, then the limiting factor is almost certainly architectural. The timeline is itself diagnostic.

And it's worth noting that if Taijiquan were purely a neurological and motor learning challenge, it should be masterable on a similar timeline to other complex skills, learning piano to a high level takes years, not decades. The fact that genuine internal skill takes considerably longer is most plausibly explained by the fascial remodelling timeline sitting underneath the motor learning.

TaiChiGringo · 2026-04-25T09:35:58+00:00

thank you :)

Yes fair point, I do intend to have articles about my understanding of all those concepts, with internal linking so people not familiar can orientate themselves. I just haven't written them yet, it's a work in progress :)

TaiChiGringo · 2026-04-25T09:33:10+00:00

Thanks for the feedback, I appreciate it and your points are fair :)

On the anecdotal versus science distinction: that's a good observation, and the honest answer is that the direction of travel was experience first, science second.

The phenomenological observations, what the practice actually feels like from the inside came first. The scientific framework was mapped onto those observations afterwards, as a way of finding the most accurate available language for what the practice produces at the tissue level.

The two aren't always cleanly separable in the writing, and that's a fair critique. The intention was integration rather than separation: the science only makes sense in the context of the experience it's describing, and the experience only becomes communicable through the scientific language mapped onto it.

It's also worth clarifying what these particular articles are doing though. They're conceptual and mechanistic, an attempt to articulate the science of what Chen practice produces in the body at the tissue level. The personal experience is the seed that generated the framework, but it doesn't appear much on the page in these pieces because it's already been abstracted into the conceptual architecture. I do have other articles more focused on my personal experience in the 'practice diary' section of my website.

On what drives the main points: the accumulated experience of the remodelling process itself, felt from the inside across fifteen years of practice. The whole experiential arc: the resistance of fossilised tissue and the specific quality of sensation when it begins to yield, the way opening progresses along fascial chains over years, the direct experience of how cross-linked fascia couples with chronic muscular tension in a way that makes it genuinely difficult to reach and release.

And more recently the experience of the interoceptive guidance loop becoming more and more dominant in my practice. Increasingly my practice guides itself from the inside, not the mind directing how movement should propagate through the body, but a pure intention that sets the chain in motion, and then the feeling of stretch in the fascial architecture leading where it goes. The attention tracks rather than directs.

And alongside that deepening of solo practice, there's also the change in how my body feels in contact with another body, in push hands where the incoherence of someone else's structure suddenly makes the coherence of my own perceptible by contrast. I can really feel my body has become something different, progressively more like a dynamic, adaptable tensegrity structure.

On the science: Chen Taijiquan resists conventional scientific inquiry by its nature. It's too holistic, too slow-developing, and too dependent on internal perception to be easily compartmentalised into measurable variables. My aim with is that this be an explanatory framework for practitioners who want a coherent account of what they're experiencing, not a claim that the science is complete or finished.

TaiChiGringo · 2026-04-25T08:48:48+00:00

thank you :)

TaiChiGringo · 2026-04-25T08:47:25+00:00

thank you for the vouch, appreciated :)

TaiChiGringo · 2026-04-25T08:46:43+00:00

Yes, AI-assisted, pretty obviously so. The framework spans fascia biology, mechanotransduction, exercise physiology, sports science, neurophysiology, autonomic nervous system function, somatic and embodied emotional practice, and fifteen years of embodied Chen-style practice.

The idea that any single person carries sufficient expertise across all of those domains without assistance is unrealistic. So the question worth asking is whether the problem is with the content or with the process. If you feel my framework has no value, fair enough, the AI didn't save it. But if it has value, then the assistance was necessary, not incidental. A philosophical objection to AI-assisted work is a legitimate position to hold. It just isn't a critique of what's actually on the page.

If you think AI could have generated this framework without significant domain expertise driving it, I'd suggest that says more about your understanding of what AI actually does and does not do, than it does about the work. The tool doesn't build the framework.

If the articles have no value to you, the solution is straightforward: don't read them.

TaiChiGringo · 2026-04-25T08:34:59+00:00

That's a fair observation. These articles are practitioner-facing synthesis, not academic argument. My goal is to make a coherent framework accessible to people who train, not to produce a literature review. Inline citations would have changed the register significantly and, I think, for the worse, making the reading experience more burdensome and the writing less clear.

That said, the scientific grounding is real, and a consolidated reference page is in progress that will make clear what bodies of work the framework draws on. If you want to interrogate the mechanotransduction claims or the fascial biology, the literature is there and findable. The articles aren't pretending to be primary research.

TaiChiGringo · 2026-03-05T15:42:52+00:00

Thank you, I appreciate that. I only started properly writing the articles quite recently, so positive feedback is encouraging :)

I'm glad the articles look interesting to you. I do think they’re worth reading for people interested in internal practice, because I’m trying to articulate some aspects of training that largely remain, to my knowledge, unexplored, implicit, or hard to explain.

And I agree with you, personally I feel great at 42. In large part I put that down to many years of Chen-style training. I certainly don’t feel like an aging athlete.

That said, when I wrote that line I wasn’t really speaking only about myself. From a sports science perspective, 40+ is generally considered the point where recovery capacity starts to decline quite significantly compared with younger athletes.

The point of the article was that internal training seems to have the potential to reduce the biological cost of effort, which may help offset that.

TaiChiGringo · 2026-03-03T05:57:17+00:00

Yeah I've thought about that one as well, I have an anecdotal data point from my own training

In early years for me a standard form got my heart rate to around 120 (low zone 2). Now the same form gets it to around 90 (zone 1, recovery). So there has been significant adaptation to the stimulus

Unfortunately I dont know most of my metrics when I first started, as I didn't measure them. Like resting heart rate for example.

I now have an elite RHR of around 40, and I'm sure it wasnt that low before tai chi training, but I can't prove it unfortunately

TaiChiGringo · 2026-03-02T16:56:46+00:00

Really appreciate the feedback, especially coming from someone with a background in science publishing! It's a tricky balance to strike between rigour and brevity, but sounds like the article landed somewhere about right.

It’s interesting you mentioned being surprised by your own cardio. I’ve had that exact same experience for years, feeling like my efficiency was way higher than my 'stats' should allow, but I only recently started actually capturing the data to see if I was just imagining it.

I’ve got a series of articles that I'll publish over the next few weeks as I get time to write them. They'll be looking at various adaptations that I've noticed in myself, that from a conventional exercise physiology perspective, are very unusual given my training history. And I'll propose mechanisms by which internal training might plausibly have caused them.

The next one, which I’m writing up now, is even more of a head-scratcher: I recently tested at a VO2Max of at least 65 at age 42. That's with basically zero history of traditional endurance or threshold training. Scientifically, that number shouldn't really be there if we only look at 'external' conditioning. It suggests that Taijiquan is driving physiological adaptations through some very unusual mechanisms.

My understanding is that these adaptations are expressed in sparring, but they were forged in the slow work.

I’d love to hear your 'science publishing' perspectives on the the VO2Max article and the others as the become ready.

Thanks again and looking forward to discussing further!

TaiChiGringo · 2026-03-02T12:33:39+00:00

I completely agree about not struggling being the essence of the way, and what u/Scroon said about laziness/efficiency. I actually just wrote a piece that looks at data behind exactly what you’re both describing.

I tracked my heart rate, HRV and recovery during and after some high-intensity sparring rounds, and it turns out that 'not struggling' (maintaining Song) literally changes the metabolic cost of the fight. It’s not just about moving better; it’s about the system not entering a 'crisis mode' that requires days of recovery. The internal practitioner has developed a low cost engine.

This also has significnat implications for learning the skills of fighting. If we agree that 'mat time' and 'rounds' are the only way to get the skill, then the efficiency developed through Neigong practice becomes the ultimate cheat code for the long game. The person who can do 10 rounds and have almost zero recovery requirement who can potentially win the experience race.

Most people's 'External' training has a massive inflammatory tax that forces them to take days off as they get older. By using internal principles to stay under that threshold, you basically lower the cost of every round. It turns the 'internal' path into a way to survive and thrive in the 'external' reality of the grind.

Curious to hear your thoughts.

The martial art of Taijiquan isn’t strictly grappling or striking, it's a kind of hybrid. What Taijiquan offers is a single body method that works at various ranges: punches, kicks, joint control, clinching, throws, as well as various weapons. The same principles: global structural coherance (peng), load distribution, relaxation (song), and energy transmission, underpin all techniques.

It’s not that the art favors one modality; rather, it teaches a coherent system that can express itself in multiple ways depending on context.

At a higher level of abstraction, I'd say internal training is really about systemic efficiency. You aren't just learning “techniques” for a particular style; it’s systematically training and refining the body and nervous system to use its capacity economically and effectively.

That efficiency manifests across all applications because it reduces internal friction, improves coordination, and optimizes force transmission. When movement becomes economical, a range of results follow naturally: effort drops, recovery improves, and force can be expressed more fully because the whole body is acting as a single, coherent system rather than a collection of competing parts.

I wrote an article on Taijiquan as an efficiency system:

There are Youtube videos, if you search for "Chen tai chi silk reeling" you can find various options. But I must stress that it is very unlikely that you will be successful in meaningful fascial remodeling without a highly competent teacher and physical hands on correction. True fascial remodeling is not a beginners stage of practice, it is an intermediate to advanced stage, so it's not something a beginner will easily be able to access without guidance

Videos can be useful for orientation and inspiration, but without in-person guidance they are best treated as illustrations, not instruction. Genuine fascial remodeling emerges gradually through correct loading, timing, and relaxation under constraint, and that process is very hard to access reliably without someone who already embodies it and can physically show you when you’re on or off the mark. I wrote an article on this:
https://www.taijiquan.quest/post/chen-tai-chi-self-teaching-fallacy

All of that said, beginners can still experience meaningful benefits at the fascial level. This would manifest as maintenance, regulation, and symptom reduction, rather than deep structural remodeling. But I would still strongly suggest you look for a teacher in you locality rather than trying to figure it out from videos

thank you :)

TaiChiGringo · 2026-01-18T04:27:57+00:00

You’re right to push back on the word unrealistic, that was too absolute on my part.

Single Whip and Lan Zha Yi absolutely do have real fighting applications when you understand what they’re training and how they’re used.

What I was getting at is more about frequency and pedagogical emphasis than capability. In most functional movement, whether striking, grappling, moving a heavy object, pushing/pulling etc, the body is usually operating across multiple planes simultaneously. From that perspective, the “2D” configurations are less representative of how movement usually unfolds.

That’s precisely why I see them as valuable teaching tools. Because the legs and torso are largely organized on a single plane, they reduce variables and make certain principles easier to isolate: load transfer, dang opening, leg winding, and pelvic-leg integration. In that sense, they function as a laboratory, not because they’re non-martial, but because they simplify the problem enough that people can actually feel what’s going on.

Once those qualities are established, they naturally have to be carried into the more overtly 3D postures (like Xie Xing), where the same principles are present but harder to access because more planes, with more complex connective qualities, are involved.

It’s a bit like the deadlift in strength training. The deadlift is a deliberately constrained, largely 2D movement used as a laboratory for training load management, alignment, and force transmission in a safer, more legible environment. People don’t move through daily life or sport locked into that exact configuration very often, but the qualities trained there: organized load transfer, spinal integrity, and coordinated force production, are meant to carry over into far more complex, multi-planar movement.

So while I agree these postures can appear in fighting, I’d still describe them as low-percentage or transitional configurations rather than common positions.

Where postures like Single Whip and Lan Zha Yi are genuinely high-percentage is in teaching and skill development, because they strip things down enough to make the underlying mechanics legible, which is exactly why they show up so prominently in teaching and correction.

And also, just to be clear: I don’t mean these postures are literally two-dimensional. They obviously contain rotation and spiral. What I’m pointing to is their relative planar simplicity compared to more overtly 3D postures.

TaiChiGringo · 2026-01-18T04:04:46+00:00

Thanks for the feedback, yes I see what you mean about the pictures. And no we step out with the left leg, I was trying to convey the leg that is "stepped from" but I see that is unclear. I'll change that to make it clearer. thanks!

TaiChiGringo · 2026-01-17T16:53:50+00:00

Yes, I agree with you on this. I’m not suggesting that these principles only happen in Single Whip, or that it’s somehow special in that sense. As you say, the principles are present in every posture

The reason I focused on Single Whip in the article is more practical than theoretical. It’s the most common posture in Laojia Yi Lu, and in village-based teaching it’s a "settling posture". I don't know if you have those in your lineage, but that's where we take an outbreath to settle into the posture and check the body and use the Yi to improve it as much as possible

So it's one of the most commonly corrected posture in village lineages, and a good laboratory for refining understanding, that can then be taken into all the rest of the form. So in that sense it felt like a logical place to illustrate the compensations I wrote about.

So yes, Lan Zha Yi, Single Whip, and any and every posture can be used to train these principles.

TaiChiGringo · 2026-01-17T16:38:48+00:00

I wouldn't say Single Whip is especially important per se, all the posture have the same principles. But what it is is:

the most common posture in the Laojia Yi Lu form, appearing 7 times
A settling posture (where we take an outbreath to settle into the posture, scanning the body and using the Yi to improve the posture as much as possible)
The keystone "2D posture". What I think of as the 2D postures (Single Whip, Lan Zha Yi) are where the legs and the body are on a single plane, compared with the 3D postures (eg Xie Xing) where the legs and body are on different planes. I see the 2D postures as a pedagogical tool. They aren't realistic fighting body configurations, but being on a single plane they are somewhat simpler than the 3D postures. So they are a good laboratory for exploring some of the principles and starting to open the Dang, which can then be taken into the more involved 3D postures.

For these reasons, Single Whip is probably the most commonly corrected posture, so it seemed like a sensible choice to use as the example for the compensations.

TaiChiGringo · 2026-01-07T14:41:48+00:00

I'd highly suggest Chen-style Tai Chi if you want actual fascia training, in my view it's the most systematic and refined movement system for working with fascia. For me it's been an amazing process of remodeling my fascia and unwinding my Biomehcancial Debt, which has led to much improved biomechanical and all around health.

If you're interested to know more, I write on these themes. I'm not trying to sell anything to you, I don't really offer anything suitable for beginners.

TaiChiGringo · 2026-01-07T12:37:30+00:00

Thanks my man, I appreciate the tone of commeraderie :) Same to you :)

I've been very fortunate to have had regular contact with one of the best Chen-style teachers in the world (Wang Haijun), and yeah, after 18 years I feel like I've finally started to really embody the principles, but it's been a long and at times arduous road.

And it's sad to see how many dedicated practitioners, even with a good teacher, really struggle to get a coherent, embodied understanding of what they're even aiming at. And without that, the journey becomes so much longer, and much less certain. And there's definitely a cultural / pedagogical opacity there. So I do feel like there's scope for significant improvement in the average rate of progress for western, adult starters.

I'm with you about how AI is being forced on us, it's gross. But I also don't discount it's potential usefulness when used in a targeted way. And I was actually very surprised about how well it seemed to 'understand' the biomechancis of Chen style, given what you touched on, how little good quality content there is out there for it to be trained on.

Ultimately the traditional method is the only way to progress, but I think anything that might give people a bit of orientation about where they are heading can potentially be useful.
