Most advice on how to choose a tai chi teacher starts with lineage: who taught whom, which family style, how many generations back. Those facts are real, but most beginners cannot check them, and they say little about whether a person will teach an adult with stiff knees well. What you can check is behaviour. In a trial class or a course preview, a teacher shows within minutes how they pace a lesson, answer questions, correct mistakes and respond to a body that cannot do everything.
This guide covers what to watch for, in local classes and online courses alike, and ends with a short scorecard you can carry into your first session.
Why your first teacher matters more than your first style
Yang, Chen, Wu and Sun are the names you will meet most often, along with the short 24-form that many community classes teach. Each has its own look, but a beginner in any of them spends the first months learning the same basics: how to stand, how to shift weight, how deeply to bend the knees, how to breathe while moving slowly.
A teacher sets those habits. One who hurries you into low stances or long sequences teaches you to override your body’s signals. One who keeps things small and asks you to notice what you feel teaches you to practise in a way you can keep up for years. You can change styles later, and many people do. The habits you build in the first months travel with you.
If you are still deciding whether home practice has run its course, six signs your home Taiji practice is ready for a live teacher will help you judge the timing before you start looking.
Green flags you can see in the first ten minutes
You do not need any Taiji knowledge to read these. They are about how the teacher treats the people in the room, or on the screen.
- The class starts gently. There is a period of standing, loosening or breathing before any choreography. A class that opens straight into a form gives stiff joints no time to warm up.
- Few new things at once. A good teacher introduces one small piece, repeats it several times, then adds the next. If you are lost within five minutes, the pacing is wrong for a beginner.
- Plain language. Terms such as “peng” or “sinking the qi” are fine when they are explained in everyday words. Jargon used as decoration is a bad sign.
- Options are offered out loud. You hear things like “if that is too deep for your knee, come up a little” without anyone having to ask.
- Newcomers are noticed. The teacher asks about injuries or health concerns before or at the start of the class, even briefly.
- Questions are welcome. The teacher answers them directly, or says honestly that they will think about it. They do not say “you will understand later.”
Also watch how the teacher corrects people. A good correction is specific (“let your knee point the same way as your toes”) and delivered quietly. Public embarrassment or a general sigh at the group tells you what a bad week of learning would feel like.
How a good teacher handles stiff knees, hips and shoulders
Taiji is slow and low impact, but it still asks a lot of the knees, hips and shoulders. Holding a half-bent stance is a real workload for the legs, and the weight shifts are constant. A teacher who works with midlife and older students should have specific habits.
For knees, a good teacher teaches shallow stances first and treats depth as something that comes later or never. They point out that the knee should track in line with the toes, and they avoid asking students to twist on a planted foot. If you want to see what these adjustments look like in detail, five small adjustments that make Taiji kinder on sore knees covers them.
For hips, look for smaller steps and shorter stances, with no pressure to turn out or open further than feels comfortable. For shoulders, a good teacher lets the arms stay lower than the demonstration and reminds people to release the shoulders rather than lift them.
A good teacher also tells you what to do with pain. Muscle tiredness in the thighs after a few minutes is common. Sharp pain or pain inside a joint is a reason to stop, ease off, and talk to your own doctor or physiotherapist. The US National Center for Complementary and Integrative Health (NCCIH) advises people to tell their healthcare providers about any complementary practice they take up, and a teacher who says the same is showing sound judgement.
Ask whether a seated or chair-supported version of the movements exists. A teacher who has one ready has taught people with limits before.
Vetting an online course: what the preview, the pacing and the feedback should show
An online teacher cannot see you, so the course itself has to do the work that a watching teacher does in a room. The preview is your best evidence, so use it properly.
Watch a full lesson, not a highlight reel. A trailer with music and fast cuts tells you about the marketing. A full lesson shows you how the teacher actually teaches. If the course offers only a trailer, that is information too.
Check the pacing. Follow along in your living room. A good lesson lets you keep up without pausing every ten seconds, repeats each movement enough times to learn it, and breaks sequences into small parts. Check the camera angle as well. You should see the teacher from the front and ideally from the side or back, and it helps if the teacher faces the same way you do so you are not mentally mirroring left and right.
Listen for limits. Does the teacher say anything about stance depth, pain, or doing less? A course that gives every movement at full depth and never mentions modification was designed for a different student than you.
Look at the feedback route. Find out how you can ask a question and how quickly it will be answered: a comment section the teacher actually reads, a live Q&A, or a way to send a short video for review. A course with no route to a human is a video library, which can still be useful, but price it as one.
Read the access and cancellation terms before paying. Check whether you keep access, for how long, and what happens if the course does not suit you. Ask the seller if the page is unclear.
The general vetting principles overlap with those for a related practice, and how to choose a Qigong teacher when you are new and a little stiff is worth a read for the shared groundwork.
Vetting a local class: the questions to ask and the trial lesson to request
A local class gives you something a video cannot: someone who can see your knee collapse inward and say so. It also takes more effort to evaluate, because you commit time, travel and money. A few questions before you turn up save a lot of disappointment.
- Is there a trial class, or can I watch part of a session first?
- Is this class for beginners, or will I join people who already know the form?
- How many people attend, and does the teacher give individual attention?
- What happens if I have a sore knee, hip or shoulder? Is there a seated option?
- How is payment structured: per class, monthly, or a block up front?
- Where did you train, and how long have you been teaching? (NCCIH suggests asking about an instructor’s training and experience. A good teacher answers plainly and does not take offence.)
Ask for one paid trial class or a drop-in session rather than a term package. Arrive early so you can talk to the teacher and see the room. Check practical things as well: whether the floor is hard or slippery, whether there are chairs, and whether you can get there without stress, since a class you dread reaching is a class you will stop attending.
During the trial, stay at the edge of your comfort. Do less than the room does if you need to, and watch how the teacher responds. A good one notices and nods. A poor one pushes or ignores.
Red flags and big promises: what a teacher should never say about health
Taiji has a reasonable body of research behind it, but the findings are measured. The 2019 American College of Rheumatology and Arthritis Foundation guideline on osteoarthritis conditionally recommends tai chi for knee and hip osteoarthritis. “Conditionally” means the recommendation is not a strong one, and no guideline says Taiji cures arthritis. NCCIH describes tai chi as generally safe when practised with a qualified instructor, and summarises the research on benefits as promising for some conditions and limited for others.
So the honest language from a teacher sounds like “many people find it helps their balance and relaxation, and results vary.” Walk away from anyone who says things like:
- That Taiji will cure arthritis, diabetes, cancer or any other disease.
- That you can reduce or stop medication or treatment because you practise.
- That a guaranteed result will arrive in a set number of weeks.
- That your pain exists because your qi is blocked, stated as established fact.
- That doctors are wrong about your condition.
Behavioural red flags matter just as much:
- You are pushed into deeper positions or adjusted physically without being asked.
- Questions are discouraged or answered with mystery.
- The teacher claims that only they teach the real form.
- You are pressured to pay for a long package before you have tried a class.
- Sharp pain is treated as something to push through.
One of these on its own is worth a second look. Two or more are a reason to leave.
Online, local or both: matching the format to your joints, budget and temperament
Neither format is better in general. Each fits different people.
Local class Online course Alignment correction A person can see and adjust you Only what the video explains Pace Set by the group Set by you; you can pause and repeat Bad joint days You may skip or sit out You can shorten or modify freely Accountability A fixed time and other people Depends on your own routine Cost Compare the total per month of attendance Compare the total per month you actually use it
If your joints are very stiff and you are anxious about keeping up, an online course lets you practise without an audience and stop whenever you need to. If you tend to drift away from solo routines, a weekly class gives you a fixed appointment. If you are shy, you might start online and move to a class once the movements feel familiar.
Many people end up using both: a local class once a week for correction and company, and an online course for short sessions between. If you choose that route, make sure the two teachers teach compatible basics, or ask your local teacher to look at what you are practising. Compare total cost over a few months, not just the first payment.
A simple scorecard to carry into your first trial class
Keep it short enough to remember in the room. After the class or the preview, ask yourself three questions:
- Did the teacher adjust to the people in front of them? Look for slower pacing, options for sore joints, and answers to questions that were useful.
- Did I feel free to do less? You should be able to reduce depth, skip a movement, or stop to rest without apology or pressure.
- How did I feel an hour later and a day later? Mild muscle tiredness and a calmer mind are reasonable. Sharp joint pain, anxiety about going back, or a feeling of having been sold something are not.
Then run a quick check against two lists.
Pass: gentle start, small steps, plain explanations, options offered, honest health language, a clear way to ask questions, fair terms.
Walk away: health cures or guarantees, pushing through pain, discouraging questions, pressure to pay up front, and any claim that you should rely on the teacher over your doctor.
Before you pay for anything, book one trial class or watch one full course preview this week, and take the three-question scorecard with you. Notice how you feel afterwards, not how impressed you were.
