The US National Center for Complementary and Integrative Health advises practising yoga under the guidance of a qualified instructor, noting that learning on your own without supervision has been associated with increased risks. That advice raises a practical question: how do you tell whether a teacher is qualified and right for you?
This guide covers what credentials mean, what to ask, and what to watch for in your first classes. It does not rank teachers or schools.
What credentials tell you, and what they do not
Ask the teacher where they trained, which credential they hold, and how to check it with the issuing organisation. Yoga Alliance publishes standards for its registered-teacher designations; other training routes also exist.
A registry entry is evidence of meeting that organisation’s requirements, not a medical qualification or a guarantee that a particular class is right for you. Ask about experience with the class format and population you need.
Questions to ask before booking
Good teachers answer these plainly and do not oversell results.
- Where and when did you train, and how long have you been teaching?
- Do you teach classes suitable for complete beginners?
- How do you handle students with injuries or health conditions?
- Do you give hands-on adjustments, and can I opt out?
- How many students are usually in a class?
- Do you offer one-to-one sessions if I need a more tailored start?
What to notice in the first class
Observe these during your first two or three sessions.
- They ask about injuries, conditions or pregnancy before or at the start of class.
- They give clear verbal instructions and demonstrate when needed.
- They offer options and props without making them feel like a lesser choice.
- They notice when someone is struggling and offer an alternative.
- They ask before touching, or explain how to decline adjustments.
- They keep the pace appropriate to the level advertised.
If you have a health condition
NCCIH advises that pregnant women, older adults and people with health conditions talk with their health care providers and with the yoga instructor about their individual needs, and lists conditions such as knee or hip injuries, lumbar spine disease, severe high blood pressure, balance issues and glaucoma as reasons poses may need modifying.
Look for a teacher who is comfortable adapting poses, asks follow-up questions, and is clear about the limits of their role. A yoga teacher can adapt a class; they are not a substitute for diagnosis or treatment from a clinician.
Red flags
One of these is enough reason to try someone else.
- Promises that yoga will cure or treat a specific disease.
- Pressure to push through pain or to match others in the room.
- Adjustments given forcefully or without consent.
- Dismissing a health concern or telling you to stop medical treatment.
- Pressure to buy supplements, products or expensive packages as part of the class.
- No interest in whether anyone is new or injured.
Choosing online teachers
For live online classes, the same questions apply, plus one: can the teacher see you, and do they give individual feedback? For recorded classes, check that the teacher explains options clearly and warns about poses that are not suitable for everyone. Recorded teachers cannot adapt to you, so choose beginner content and preview a session first.
Fit checklist
If most of these are true after a few classes, you have likely found a good fit.
- Training background disclosed and checkable.
- Asked about your health and experience.
- Clear instructions you could follow.
- Offered options, props and rest.
- Respected your consent for touch.
- No health promises or product pressure.
- You left tired in a good way, not hurt or confused.
