What Is Neigong? Internal Skill Training Explained
10 Minute Read
What Is Neigong?
Neigong (内功), often written Nei Gong (and sometimes Nei Kung or Nei Gung), means “internal skill.” This refers to the training methods found in Chinese martial, Daoist, and Qigong traditions that develop internal coordination, breath, structural alignment, and the deeper cultivation of Qi within your body.
Through progressive training, Neigong leads to refined control over your movement, energy, and awareness. With dedicated practice, you can potentially reach profound levels of Qi cultivation, transmission, and highly advanced skillsets.
You can think of Neigong as the ‘secret sauce’ of Gong Fu 功夫 (Kung Fu). It’s often what lies behind the phenomenal feats that appear almost implausible (or even impossible) to the uninitiated—effortless strength, incredible balance, or the ability to generate surprising power with very little visible movement.
At the same time, it’s important to separate genuine training from fantasy. Neigong can develop truly remarkable skill and ability—strength, agility, coordination, and dynamic structural integration. The Kung Fu “Hollywood” version, however (as you might expect), is mostly enchanting fiction designed to sell movie tickets.
“Authentic Neigong is a deep, internally focused understanding of the physics, physiology, and biomechanics within the human body—it is not mystical and arcane sorcery.”
For those who are curious about these practices, this is encouraging (yes—you can do this!). The skills developed through Neigong are not supernatural—they are trainable. Yet because the training is subtle and often transmitted within lineages, the skill often remains encoded, guarded, and even shrouded in mystery. And so the allure and mythology remain. This can make it difficult to separate fact from fiction, and also to know if someone out there selling “Neigong training” actually knows what they’re doing.
So let’s pull the curtain back and take a closer look at the skills and practices involved. This should provide you with a solid foundation for your own explorations, and give you enough knowledge to develop the necessary discernment as you seek deeper training.
What Does Neigong Actually Train?
Neigong is often described in mysterious terms—which, while evocative, can make it genuinely hard to understand what you’d actually be doing in your training.
So let's get practical.
At its core, Neigong develops the body's internal organization and regulatory capacity. The practices refine how your structure, breath, connective tissue, nervous system, and Qi all work together. Ultimately, making your body a unified and highly responsive system. Think less a "collection of independent parts" and more an "integrated, living whole.”
In practical terms, that development shows up across several closely related areas:
Postural architecture: The body is organized around a trained stable internal structure. Proper alignment of the spine, pelvis, ribcage, and limbs allows everything to work together through tensegrity. When this clicks into place, your body functions like an elastic, pressurized container—capable of transmitting force and movement with surprising ease.
Breath mechanics: This one’s huge, and often underestimated. Classical texts describe different breathing patterns (such as "natural" or "reverse" breathing) that coordinate internal movement, circulation, and energetic flow in distinct ways. Neigong places serious emphasis on how you breathe—developing refined control of the diaphragm and ribcage so that your breath can actively direct internal pressure and movement throughout the body.
Connective tissue and tendon conditioning: Here's where Neigong starts to depart from conventional strength training. Rather than relying primarily on muscular effort, the training builds and conditions the body's connective tissue network. Tendons and fascial structures develop a level of elasticity and resilience that allows force to be transmitted through the body with remarkable efficiency. This is often what practitioners mean when they talk about "internal strength.”
Nervous system regulation: A significant piece of internal training is about refining sensory awareness and your body's ability to self-correct and adapt. You become able to directly influence your stress responses, sharpen your proprioception (your body's sense of its own position), and develop deeper interoception (a felt sense of what's happening inside you).
Why Would I Want To Learn Neigong?
As alluded to above, authentic Neigong adds immense depth, potentially increased power, and significant advantages to your training (regardless of style, lineage, etc.). Generally considered advanced training, these practices can take your skills to the “next level” (and well beyond).
The benefits of Neigong successfully integrated into your practice can produce:
Greater levels of Qi transmission—expressed through what’s called Fajin 發勁—a direct expression of refined postural architecture and connective tissue conditioning working together
Increases in “energy” and stamina—as breath mechanics become more efficient, less effort produces more output
Improved balance, agility, and power— built on the structural alignment and tensegrity developed through foundational training
Sharper awareness and quicker recovery—the results of a well-regulated nervous system
The phrase “work smarter, not harder” comes to mind here. When embodied, true Neigong skills can transform certain practices into almost effortless activities.
With this training, your ability to understand, access, transmit, and maintain levels of Qi will change dramatically. Most students experience higher levels of efficacy, stamina, and vitality in their practice—and all with less effort.
To get there, however, requires foundational skills and a healthy dose of dedicated training.
Neigong Exercises
First and foremost, it is important to understand that Neigong training is what we might call “principle based.”
This is to say that the underlying skills are universal “principles” in process, and therefore can be applied to a vast array of practices. So much so that—to a serious student or practitioner—washing your dishes can be done with neigong!
So while it’s a common misconception to think that there are “Neigong exercises” (as in a calisthenics type workout way) to train—truly effective practices are more about training techniques that involve your internal energetic pathways and engagements.
While anything that is trained could be thought of as an “exercise,” it is worthy to note that a lot of true neigong training practices—because of the “internal” nature—may not appear novel or anything special to an outside observer (unless you know what you’re looking for).
This is not to dismiss the physical aspects to Neigong training—this is very much a part of the process. However, neigong training is intently focused on the manifestations of an internal cultivation process.
An example of less-than-ideal structure that could prevent successfully training advanced Neigong 内功 skills.
Is Neigong Safe? What to Know Before You Start
While Neigong is generally principle based—you still need a “form,” or practice, in which to apply the principles.
There should be a certain level of competency within your form or practice before any advanced training is applied. Otherwise, at best, you will end up wasting time and energy—or worse, possibly risk personal injury.
Think about this: What would happen if you (were able to) plug-in a hair dryer (built for 110 volts) into an outlet made for a clothes dryer (240 volts)?
Answer: Nothing good for the hairdryer.
Neigong has the potential to significantly increase the intensity of Qi 气 flow moving through the body—like increasing voltage in a circuit. While this is generally viewed as a really positive thing—it is important to pair the correct “appliance” (in this case your body), with the proper “voltage” (level of Qi transmission). This is why it is imperative to have an established, and solid, foundational practice (like Qigong) to build Neigong training into.
Good foundational practices are designed to “rewire” your system to be able to handle the increased energetic flow— gradually conditioning the connective tissue, refining breath mechanics, and building the nervous system’s capacity to handle that more advanced training demands. These aren't prerequisites you check off and leave behind; they deepen in parallel with your Neigong development.
““Neigong training of actual depth is often guarded and not taught to the general public. Teachers who truly understand the potential of these skills are rarely so cavalier.””
Knowledgeable instructors are aware that teaching actual advanced practices without preparation is rather irresponsible and can potentially even be dangerous. A good teacher will incorporate Neigong principles progressively as you gain greater proficiency in your training.
For this reason, we always advise caution—and a fair bit of skepticism— when it comes to advanced trainings that are made open to anyone (with a valid credit card, of course). More often than not, these marketed “Neigong trainings” are simply a misuse of language (you don’t know what you don’t know, right?), or—regrettably—the occasional (and very intentional) appropriation to make money.
Qigong and Daoyin (导引) practices have been in the awareness of Western audiences just long enough that “secret internal energetic arts” (Neigong) provides a distinctive and pretty alluring marketing tactic.
Somewhere between the intentional or otherwise, Neigong sometimes also gets promoted as “energetic internal alchemy” which is a conflation with Neidan 内丹 practices.
Authentic Neigong Training
All systems of Neijia 内家 (Chinese internal martial arts) training should already have neigong principles built in. This is true regardless of the nature of practice (martial, health, or spiritual). It is important to note the “should” here…
Time, politics, and cultural elements have all contributed to the circulation of training that lacks actual neigong principles. The unfortunate result has been a dilution of some practices, and even loss of knowledge from entire training systems. For better or worse, this has led to widespread modern training that may speak the language—but is lacking in practical knowledge and true depth.
Compounding this issue, true training is often (some may argue, appropriately) guarded and kept “secret.” This is usually for the sake of personal safety, accountability, and also the close relationship of neigong to internal alchemical practices (known as Neidan 内丹).
This has only made reliable information increasingly rare.
The good news?
Authentic neigong training does still exist in the modern era (you just won’t find it on social media). And, even better news: True skill is within the grasp of most anyone who is willing to put in the time and training required.
So the question becomes: how do you actually find that training?
So, How Do I Learn Neigong?
We get this question a lot. The short answer is to find a good teacher near you (or be willing to travel to a qualified instructor). It is best to learn in-person, under the guidance and direct observation of someone who knows what they’re doing.
Provided the skills are known to them, a good martial arts, Qigong, or spiritual teacher with a Neijia system background should be able to teach you effective—and possibly even profound—Neigong practices.
Finding a good teacher with whom you resonate can sometimes be a challenge. Doing some research and educating yourself (you’re off to a good start!) will help in both clarifying what you’re actually looking for, and go a long way in finding the teacher who can best help you.
Understanding that Neigong specific training is an intermediate to advanced level of practices, it’ll be assumed you have some background to measure against here. If you’re just getting started and looking forward, know that as with most things, personal discernment comes with time and experience (and you’ll quickly figure out who or what kind of training does or does not work for you).
Regardless of where you’re at in personal practice, if you’re searching for a competent teacher to learn neigong practices, here are some essential basic questions you should absolutely be thinking about:
1. Will the teacher work with you in-person (as in IRL, not just online)? In-person instruction matters: There are so many invaluable reason to train in person! The top-of-list when thinking about advanced training like Neigong, is the opportunity for direct, tangible feedback and transmission.
There is much we can do and learn online, however, there are also many discrete skills that are really difficult to “translate” without direct, physical adjustments, palpation, or simply having someone assist in “feeling it” in your body. Anyone who has had this direct experience (and truly knows these skills) also knows that there is simply no substitution for in-person training when it comes to certain advanced practices.
2. Do they emphasize proper structure? One of the goals of neigong is to turn up the “volume” or “voltage” of Qi moving through the body—right? Well, if we look at the pathways or channels (Jingluo 经络, or otherwise) that Qi moves through, we can visualize them as you might think of a hose used to transport water. This is why postural architecture—the first and most foundational of the internal training principles—isn't optional. It's the prerequisite that makes everything else possible.
Anyone who is dismissive of structure simply will not have the direct experience or knowledge to teach skills beyond a very superficial level.
3. Are they an expert (or even knowledgable) in relevant theory? Having confidence in why you are doing something (anything!) comes from an understanding of how it works. All Neigong (as well as tangential practices) is strongly rooted in well-established and teachable theory—most of which is applicable within Chinese medicine. If your questions about why something is done in a specific way is met with a “because I said so” or some lengthy non-answer diatribe (maybe involving “cosmic qi” or the like)—that’s a red-flag.
4. Are they available (or willing) to answer your questions? You’re going to mess up and need help at some point. It’s not IF, it is when something goes contrary to plan (life, right?). We all make mistakes, need help as we grow, and look toward the guidance of those who came before us. Is the person you’re seeking training from going to be available to provide the much needed assistance when the time comes? This is something to think about in the early stages of your research and it’s also another great reason to prioritize in-person instruction!
A word of advice before you go knocking on any teacher's door: advanced skills are not handed out on request. Approach any prospective teacher with patience and humility.
It’s important to understand and remember that advanced skills are earned. This requires a bit of effort beyond just establishing proper foundational skills. Any good teacher won’t teach you certain practices until you’ve demonstrated that you’re ready and truly prepared (see safety note, below).
That said, working with a knowledgeable teacher, advanced skills and deep internal techniques will quickly become a natural outgrowth of your practice.
In fact, with a skilled teacher, neigong will become the very process of your practice. You’ll start learning the principles—in a safe and effective way—before you even realize that’s what you’re learning!
Nei Gong vs. Nei Dan
Another question that often comes up is: “Neigong or Neidan—which is better?”
While the two terms sound similar and are intimately connected, it's not really a "better or worse" conversation. They are two distinct processes of internal cultivation, and a direct comparison doesn't quite fit.
Nèi gōng (内功) is generally translated as “internal skill.”
Nèi dān (内丹) is generally translated as “internal alchemy.”
Both share the character Nèi 内, meaning “internal” or “within”—and both have to do with accessing, building, and utilizing internal processes of Qi. The difference lies in their emphasis.
While a bit reductive, it could be said that Neigong is primarily concerned with developing and increasing the capacity and circulation of Qi within your body. Whereas Neidan—sometimes reductively viewed as deep Neigong processes—is focused on the transmutation of Qi (among other things) in the body. It builds upon that Neigong foundation and uses your body’s internal processes within a broader alchemical framework of transformation.
Neigong prepares the vessel. Neidan refines what the vessel contains.
Ultimately, both categories of practice involve immense increases of ability and skill. In many classical systems, Neigong training is therefore considered a necessary foundation for deeper internal alchemical work.
Regardless of your desired path, both Neidan and Neigong require a solid "root" in a foundational practice like Qigong—which raises a question worth addressing directly: if Qigong is the foundation, how does it actually relate to Neigong?
Qigong vs. Neigong?
Here at Red Thread Institute, this is not really a question. As you may recall, all Neijia 内家 (internal arts) training systems have neigong principles built right in!
Qigong is a broad category of practices. Neigong refers more specifically to internal training methods that deepen structural, energetic, and meditative skill within such practices.
In Red Thread Institute’s framework, properly taught Qigong already contains Neigong principles.
Qigong should contain components of both Wàigōng 外功 (external skill) and Nèigōng 内功 (internal skill). This is part of what makes Qigong so incredibly potent as a practice.
The obvious caveat is that proper training is progressive in nature. So while the foundational elements covered earlier—postural architecture (structure), breath mechanics, and intention—are essential to proper Qigong training, they are also the very basis from which advanced Neigong principles emerge. In a well-taught system, the two are inseparable.
As your practice develops and grows, your internal energetic training will develop proportionally—provided you’re working with a competent and invested teacher.
And with proper instruction, foundational training, and expert guidance, you may even find yourself stepping into the truly transformative process of Neidan.
Frequently Asked Questions
-
Not exactly — though the two are closely related. Qigong is a broad category of practice that develops breath, movement, and energetic awareness. Neigong refers specifically to the internal training principles that deepen and refine those capacities.
Think of qigong as the vehicle and neigong as the engine: a well-taught Qigong practice should already have Neigong principles built into it, but not all qigong instruction includes genuine neigong training.
-
Neigong (内功) develops the body's internal capacity — structural alignment, breath mechanics, connective tissue conditioning, and nervous system regulation. Neidan (内丹), or internal alchemy, builds upon that foundation and works toward the transmutation and refinement of Qi within a broader alchemical framework.
A useful shorthand: Neigong prepares the vessel; Neidan refines what the vessel contains. In many classical systems, Neigong training is considered a necessary prerequisite before Neidan practice begins. -
This depends heavily on your existing foundation, the quality of your instruction, and the consistency of your practice. Most students that already have a solid qigong background begin experiencing the effects of Neigong principles relatively quickly — often within weeks of working with a qualified teacher. Genuine depth, however, is a long-term development.
Like any advanced skill, neigong rewards sustained, progressive practice over years rather than months. -
No. While Neigong has deep roots in Chinese martial traditions, the principles apply equally to health-oriented and spiritual practices. What matters more than martial background is having an established foundational practice — whether that's Qigong, Tai Chi, or another Neijia (internal arts) system — and finding a teacher who genuinely understands how to transmit these skills.
-
Some conceptual understanding can be built through online resources, but genuine Neigong training is best learned in person. Many of the most important corrections and transmissions in this kind of work require direct physical contact, hands-on adjustment, and the kind of feedback that simply doesn't translate through a screen.
Online learning can be a useful supplement, but it shouldn't be the primary path for serious practice.
