What a Teacher Can and Cannot See

How to get useful correction out of a class, which is a skill, and one nobody teaches.

What a teacher can see

Gross alignment. Whether your front knee is collapsing inward, whether your back is rounding, whether your shoulders are up by your ears. Visible from across the room, and a good teacher will catch it within a few seconds of looking at you.

Effort and breath. Whether you are straining, whether your breath has gone ragged, whether you are holding it. Often audible.

Patterns across poses. The most valuable thing a teacher offers. One rounded back is an observation; a rounded back in every forward fold plus a collapsed chest in every standing pose is a pattern, and the pattern usually has one cause. Seeing that requires watching someone across an hour, which is why a teacher who knows you is worth more than one who does not.

Whether you are in the right pose at all. Sometimes the correction is not an adjustment; it is that you should be doing a different shape.

What a teacher cannot see

Sensation. They cannot tell whether the stretch you feel in a hamstring is a productive pull or a sharp warning. This is the largest gap and the one you have to close.

Where it is coming from. Two people in an identical-looking forward fold can be limited by hamstrings, by the lower back, by the hip joint, or by protective tension. From outside these can look the same.

Pain, unless you show it. Many people's face gives nothing away.

Your history. Unless you tell them. An old shoulder dislocation, a fused vertebra, a knee that dislikes rotation — none of it is visible, and all of it changes what they should ask of you.

What is happening in a big class. A teacher with thirty people is doing triage. They will catch the dangerous things and miss the subtle ones, and that is not negligence; it is arithmetic.

How to get more

Arrive early and say one specific thing.

Not "I have a bad back." That tells them almost nothing. Something like: "My lower back complains in backbends, particularly Camel, and it is fine in everything else."

Specific, short, actionable. Thirty seconds before class is worth more than an hour of hoping to be noticed.

Put yourself where they can see you. The back corner is where people hide, and it works. If you want correction, be in the middle.

Ask a question after class, not during. During, they are running a class. After, most teachers will happily spend five minutes on a specific question, and the good ones enjoy it.

Ask better questions. "Am I doing this right?" is unanswerable. "In Triangle, I feel this in my lower back rather than my side — what should I change?" gets you a real answer.

Say when an adjustment does not work. If a teacher moves you into a position and it feels wrong, say so immediately. They cannot feel what you feel and they are relying on you to tell them.

Hands-on adjustment

You can decline it. Always, for any reason, and you do not need to explain. Most studios now ask; if yours does not, say so at the start. A teacher who reacts badly to that is telling you something useful about the studio.

A good adjustment is small, clear, and makes the pose immediately easier or more obviously correct. You should be able to keep the change after they let go.

A bad adjustment takes you deeper into a shape by force. Depth is not the point and a teacher pushing you further into a stretch is doing something they cannot judge the safety of, because they cannot feel what you feel.

If it hurts, say so instantly. Not afterwards.

What to do with a correction

Apply it, then check it stays. Most corrections are lost within two breaths. The skill is holding it once the teacher has moved on.

Ask what it should feel like if it is not obvious. A correction you cannot feel is a correction you cannot reproduce alone.

Write it down after class. One line. Over a few months you will notice the same three corrections recurring, and those three are your actual work.

The limits worth knowing

A yoga teacher is not a clinician. Training varies enormously — a 200-hour certificate is four weeks of full-time study. That is enough to teach a class safely and it is not enough to diagnose or treat an injury.

A good teacher will say "I do not know, go and see someone." Treat that as a mark of quality rather than a failure.

Nobody can see inside a joint. If something hurts in a way that concerns you, the answer is a physiotherapist or a doctor, not a deeper adjustment.

Your own instrument

The gap between what a teacher can see and what matters is closed by you, and the tool is specificity about sensation.

Learn to distinguish: a broad, dull, spreading pull in the belly of a muscle, which is productive; a sharp or burning sensation, which is not; a hard blocked feeling at a joint, which is bone and will not change; and pain at a specific point near a joint, which should stop the pose immediately.

A teacher who watches you for a year is enormously valuable. A body you can read is more valuable still, and it is with you every session.
