In 57 years of practicing Tai Chi, and several decades of teaching it, I have watched thousands of beginners walk through the same handful of doors that lead nowhere. Not because they lack discipline. Not because they lack ability. Almost always because nobody told them what the actual mistakes look like from the inside.
Most articles on this topic give you a list of postural corrections. Bend your knees more. Keep your back straight. Those things matter, but they are symptoms. The mistakes that actually keep beginners stuck are almost always mistakes in understanding, not mistakes in shape. Fix the understanding and the shape corrects itself far faster than you would expect.
I have organized this article around the mistakes I see most often, in the order I typically see them appear. If you are new to the practice, or have been at it for a year or two without the results you expected, one or more of these is probably part of the reason.
None of these mistakes are dramatic on their own. That is exactly what makes them worth naming. A slightly collapsed posture or a slightly rushed approach to fundamentals does not produce an obvious injury in week one. It produces a slow accumulation, months or years of repeating a pattern that is close enough to correct that nobody stops to question it. By the time it shows up, usually as a nagging knee, a plateau in progress, or simply the sense that practice is not delivering what it promised, the habit is well established and takes real attention to unwind. Catching these early is far easier than correcting them later, which is the entire purpose of this article.
Mistake 1: Confusing Softness With Being Limp
This is the single most common misunderstanding in Tai Chi, and it happens almost immediately. New students hear that Tai Chi is about relaxation and softness, and they translate that into going limp. Arms hang loosely. Posture collapses. The whole body goes slack, as though relaxation means the absence of structure.
Genuine softness in Chen style Tai Chi is not the absence of structure. It is structure without unnecessary tension. There is a real difference between a body that is aligned and released, and a body that has simply given up its shape. A rope hanging from a hook is limp. A rope holding a weight, with no wasted tension anywhere along its length, is soft in the way we mean it in this practice.
The correction is to stop thinking about relaxation as an absence and start thinking about it as an economy. Use exactly the tension required to hold the posture and support the movement, and release everything beyond that. This is what we mean by song, and it takes years to refine, but the direction has to be correct from day one or you spend those years compounding the wrong habit.
Mistake 2: Rushing to Learn the Form Before the Fundamentals
Almost every new student wants to learn the form. That is understandable. The form looks like Tai Chi, and learning a sequence of movements feels like progress in a way that standing practice and silk reeling exercises do not. So students push through the fundamentals as quickly as possible to get to the part that looks impressive.
This is backwards, and it is one of the most damaging mistakes because it is invisible for a long time. Silk reeling teaches the body how to generate and transmit movement from the ground up, through the waist, into the arms. Stance training teaches the legs to bear weight correctly and shift it without collapsing the structure. Wuji standing teaches the whole system what genuine relaxation and alignment actually feel like. Skip these, and you can absolutely learn the shapes of a form. What you cannot do is generate the internal quality that makes the form worth practicing in the first place.
I tell every new student the same thing. The form is not the practice. The form is where the practice gets expressed once you already have it. If you want the real benefit, whether that is health, martial skill, or both, the fundamentals deserve more of your early time than the form does, not less. Our complete beginner’s guide lays out exactly how much time to spend where in your first year.
Mistake 3: Losing Alignment With Gravity
After 35 years as a chiropractor, in addition to my decades in this practice, I can tell you with confidence that most chronic pain has a postural component. Rounded shoulders, a forward head, a locked or hyperextended knee, weight sitting too far forward or back on the foot. These patterns are so common in daily life that most people do not even notice them anymore. They simply feel normal.
New Tai Chi students bring these same compensations directly into their practice. The knee tracks inward instead of over the foot. The tailbone tucks or juts. The chest collapses forward or the chin pokes ahead of the spine. None of this looks dramatic from the outside, which is exactly why it goes uncorrected for so long, and why it matters so much. Every one of those small misalignments is a place where the body is working against itself instead of with gravity, and over months of repetition that adds strain exactly where you least want it, especially in the knees and lower back.
This is why alignment is the first rule we teach, before anything else. Get a qualified set of eyes on your stance early, whether that is a teacher, a video review, or a very honest mirror, and correct these patterns before they become habitual. It is far easier to build correct alignment from the start than to unwind years of a compensated stance later.
Mistake 4: Treating Practice Like a Class Instead of a Habit
A large number of beginners only practice on the days they attend a class or follow along with a video. Everything else is a rest day by default. I understand the appeal of this. Life is busy, and a scheduled class provides structure that daily solo practice does not.
But Tai Chi does not train the nervous system the way an occasional workout trains a muscle. The benefits, whether you are chasing better balance, lower blood pressure, or a calmer stress response, come from consistent daily signal, not from concentrated weekly effort. Fifteen minutes every day builds a different nervous system than ninety minutes once a week, even though the second option adds up to more total time. I have watched this play out with students for decades. The ones who build a small, sustainable daily habit improve faster and retain more than the ones who only show up for class.
If daily practice feels like an impossible standard right now, start smaller than you think you need to. Our article on building a daily Tai Chi practice walks through exactly how to make the habit stick without willpower doing all the work, and our guide to practicing at home covers the practical side of finding the time and the space.
Mistake 5: Learning Exclusively From Video, With No Correction
Video has made Tai Chi more accessible than at any point in its history, and I say that as someone who has built video content myself because I believe in what it can do. But video alone has a ceiling, and beginners consistently overestimate how close to that ceiling they can get on their own.
The problem is not motivation or attention. It is that you cannot see your own alignment the way an outside eye can. A subtle knee deviation, a shoulder that creeps up under tension, a weight distribution that is slightly off, these are exactly the kinds of errors that feel correct from the inside while looking wrong from the outside, and they are also exactly the kinds of errors that compound the longest before they cause a problem. Video is an excellent way to learn material and to practice consistently between sessions. It is not, on its own, a substitute for periodic correction from someone qualified to give it.
If you are practicing entirely on your own right now, the single highest leverage thing you can do is find a way to get corrected, even occasionally. That might mean an in-person teacher, a workshop, or a video review with a qualified instructor. Our guide on how to find a Tai Chi teacher covers exactly what to look for and what to avoid.
Mistake 6: Forcing or Directing the Breath
Somewhere along the way, a lot of beginners pick up the idea that Tai Chi requires a specific breathing pattern, inhale on this movement, exhale on that one, and that getting the breath wrong means doing the movement wrong. So they spend their practice consciously managing their breath instead of letting it respond naturally to the movement.
This is a mistake in the opposite direction of most of the others on this list. Instead of doing too little, the student is doing too much, layering a mental task on top of the physical one and, in the process, creating exactly the kind of tension the practice is meant to release. Correct Tai Chi breathing is not something you impose. It is something that emerges once the movement itself is correct, once the body is aligned, the joints are open, and the movement is generated from the legs and waist rather than muscled through the arms. When those conditions are met, the breath naturally deepens and slows on its own, without any conscious direction at all.
My advice to beginners is almost always the same. Breathe normally. Do not hold your breath, and do not force a pattern onto it. Let your attention stay on your structure, your alignment, and your relaxation, and trust that the breath will follow the movement rather than the other way around. This single adjustment, simply releasing the mental grip on the breath, often produces an immediate and noticeable increase in how relaxed the whole practice feels.
Mistake 7: Comparing Your Progress to Someone Else’s Form
The last mistake I want to name is one that costs students motivation rather than technique. New practitioners see an advanced student, or a video of an experienced teacher, and measure their own early practice against that standard. The comparison is almost always demoralizing, and it is also almost always meaningless, because you are comparing your first year to someone else’s twentieth.
Tai Chi rewards patience more than almost any physical practice I know. The internal changes, the relaxation, the alignment, the connected movement, take years to mature, and they mature at their own pace regardless of how much you want to rush them. Measure your practice against your own practice from six months ago, not against a lineage holder’s decades of daily repetition. That is the only comparison that will keep you honest and keep you encouraged at the same time.
If you are working through our Tai Chi Basics course, this progression is built in deliberately. Each section builds the fundamentals in the order they need to be built, so you are not skipping ahead into the form before your body is ready for it, and you are getting a structured path instead of guessing at what to work on next.
What All Seven Mistakes Have in Common
Every mistake on this list comes from the same root cause: prioritizing what looks like progress over what actually builds it. Softness that looks relaxed but is really collapse. A form that looks advanced but sits on top of weak fundamentals. A practice schedule that looks busy but is not consistent enough to train the nervous system. A breath that sounds deliberate but is really interference. None of these are failures of effort. They are simply the natural result of not yet knowing what to look for, which is exactly what this article, and the rest of this site, is here to correct.
I want to be clear about something, because I see it discourage students unnecessarily. Recognizing yourself in three or four of these mistakes does not mean you have wasted your time, and it does not mean you are starting over. It means you now know where to direct your attention, which is a genuine step forward, not a setback. I have never met a serious long-term practitioner, myself included, who did not carry several of these habits early on. What separates the students who progress from the ones who plateau is not the absence of mistakes. It is the willingness to notice them and correct course.

Frequently Asked Questions About Tai Chi Mistakes
Can I fix these mistakes on my own, or do I need a teacher?
Some of these, like the daily practice habit and the order in which you learn material, you can absolutely fix on your own with the right structure. Alignment mistakes are harder to self-correct because you cannot fully see your own posture from the inside. A teacher, a workshop, or even an occasional video review from someone qualified will catch things you cannot catch alone.
How long does it take to correct a bad habit once it is established?
It varies with how long the habit has been in place and how consistently you work on the correction, but in my experience most postural and structural habits begin to shift noticeably within a few months of correct, attentive daily practice. The habit does not disappear all at once. It fades gradually as the correct pattern becomes more familiar to the body than the old one.
Is it normal to feel like I am not improving even after months of practice?
Yes, and it is one of the most common experiences beginners report. Tai Chi improvement is often invisible week to week and only obvious in hindsight over months. If you are practicing consistently and correctly, the improvement is happening even when it does not feel like it. This is one of the reasons daily practice matters so much, it gives the nervous system continuous signal even during the periods where conscious progress feels slow.
Do these mistakes apply to other styles of Tai Chi, or only Chen style?
These mistakes apply broadly across styles. The specific corrections, particularly around stance depth and the pace of movement, differ somewhat between styles, but the underlying issues, mistaking limpness for softness, rushing past fundamentals, losing alignment, inconsistent practice, and lack of correction, show up in beginners regardless of which style they are learning.

If it is not top-secret, did Grandmaster Wang Xian ever practice or teach Iron Palm?
As far as I can tell, none of the other three surviving Diamonds teach or practice Iron Palm, although there are a few Chen stylists (Guo Zhongyu and Chen Yu so far)
who at least practice Iron Palm and are willing to exhibit their skills.
I never heard this term iron palm so I have no idea what it means. I never heard Master Wang use this term.
