Reading a student through the breath: look – listen – touch
Before you “prescribe” a student a breathing practice, do the thing very few trainings teach: read how they are breathing already. Give the same cue, “breathe in deeply”, and one person fills the belly properly, another grips the shoulders and gasps, a third stops breathing altogether without noticing. If you cannot read them, you are teaching an imaginary person — not the one on the mat. This lesson hands you three “windows” onto a student's breath: LOOK – LISTEN – TOUCH. This is the skill of reading a breathing pattern (not diagnosing a condition), and it is what turns you from someone calling cues into a teacher who can actually read the person in front of them.
You cannot fix what you have not seen
Picture a doctor writing a prescription without taking a pulse or listening to the lungs. A great many teachers do exactly that with the breath: they walk into the room and call “breathe in, belly rises; breathe out, belly draws in” to everyone at once, regardless of the fact that each person is in a different pattern. The cue is not wrong, but it is one prescription handed to everybody. For someone already breathing well it is redundant; for someone breathing wrongly, the harder they follow it, the more they brace. Your first job is not to call out — it is to watch how the person in front of you is breathing.
You already have three tools, and none of them is a machine: LOOK at where the body moves and how fast or slow the breath goes; LISTEN for whether it is quiet or hurried, and for any gap where the breath stops; TOUCH — a hand on the student (or their own hand on themselves) to feel where the movement is. Those three windows look at the same breath from three sides, and together they give you a fairly complete picture of whether the student is breathing properly or straining.
To be clear, so nothing is misunderstood: you are not diagnosing a condition, and not telling a student they have a respiratory or health problem. You are reading a breathing habit — shallow or deep, braced or released, fast or slow — so you can lead them to practise accordingly. If you see genuinely worrying signs (difficulty breathing, chest pain, dizziness), your job is to stop and advise them to see a doctor, not to handle it yourself.
Wherever the body moves gives the pattern away
This is the easiest signal to read. As the student breathes in: if the belly and lower ribs widen gently while the shoulders stay still — that is the good direction, the diaphragm is working. If the upper chest and shoulders lift on every round while the belly barely moves — that is a shallow breath, crowded into the top. People breathing that way tire quickly and struggle to hold a long breath. Stand a little to the side and watch the outline of the body, and you see straight away where the movement is.
Count their breaths silently over a few rounds. A fast, short, hurried breath — barely in before it is out again — is the sign of tension, or of not yet knowing how to draw a long breath. A slow, even, deep breath — each one lasting — is the released state you want to lead them to. You do not need an exact number; the sense of “this person is rushing” or “this person is settled” is enough to tell you how to lead.
A face is an honest report of effort. A furrowed brow, a clenched jaw, pressed lips, cords standing out on the neck — the student is working at breathing rather than breathing. A good breath leaves the face loose, the jaw soft, the shoulders down. When you see a face gripping, it is usually because they are forcing the belly out by strength, or trying to breathe beyond what they can. That is the moment to say: “let the face go, breathe lightly.”
The sound of a breath tells you what the eye missed
In a quiet enough room, listen. A breath that sounds hurried, wheezy, rasping, broken tells you the student is using force to push the air through — the airway is not clear, the body is still tight. A breath that is quiet, smooth, long, barely audible means the air has become one continuous stream and the student is genuinely releasing. As Tuấn Anh teaches it: when you breathe in slowly and quietly enough, the air comes in “as a quiet, smooth, cool stream” — and your ear can hear that difference.
This is something the ear catches better than the eye: as a student works into a hard shape, many of them hold the breath automatically without knowing it — the sound stops dead for a few seconds, then bursts out in one big exhale when they release. This bracing reflex is very common (you might call it “forgetting to breathe under effort”). It takes the value out of the movement and makes the student tighter still. The moment you hear that unnatural silence, say it straight away: “keep breathing, do not hold.”
Do not only listen to the air going in; listen to it going out. Many students breathe in fairly long but breathe out in a rush, cut short, and breathe in again before they are empty. Hearing that tells you they have not been able to let go — and the out-breath is the part that brings the body to ease. It is also the bridge into Lesson 6: the out-breath needs to be longer than the in-breath.
Let the student feel it — the strongest self-correcting tool there is
This is the strongest self-correcting tool you can hand over. Have the student put one hand on the chest (near the collarbone) and one hand on the belly, breathe naturally and ask themselves: which hand is moving more? If the chest hand rides up and down while the belly hand is almost still — they are breathing shallowly, crowded into the top. If the belly hand widens first and further while the chest hand stays almost still — they are heading the right way. The beauty of it is that the student finds it themselves; you do not have to pronounce on it. What they feel under their own hand sinks in deeper than a thousand cues from you.
For someone who still cannot feel it, you can (after asking) rest your own hand lightly on their lower ribs or belly and say “breathe so that you push my hand out”. One point of contact gives them a definite target to aim the breath at. Tuấn Anh uses the same thing: a hand on the chin, a hand on the belly, to “meet their breath where it is” and count the rhythm with them. Always gently, always with permission, and respect it if a student would rather not be touched.
The cue “breathe into the belly” is an abstraction — the student has to translate it into a feeling themselves. A hand on the body turns that abstraction into something real, right under the palm. The brain learns through touch faster and more firmly than through words. Which is why one hand in the right place often unlocks what ten cues could not.
Read first, and you know where to lead from
When all three windows say the same thing — you LOOK and the shoulders lift, you LISTEN and the breath is hurried, you TOUCH and the chest hand is doing the moving — you can be sure: this student is breathing shallowly, at the starting level, and needs leading back to the root very slowly. The other way round, when all three are quiet — shoulders still, breath long and smooth, belly hand widening — they are ready for deeper work. Reading each person's level keeps you from pulling a beginner along too fast and from holding a capable student somewhere far too easy.
Tuấn Anh points to a very common fault: a student hears “the belly must rise” and immediately pumps the belly in and out to match the words — but the real breath only lasts a second or two, then comes tiredness, a tight chest, a broken rhythm. The belly filling is supposed to be the natural result of breathing in slowly and deeply enough, not something to work at. Reading the three signals lets you tell a genuinely widening belly (face loose, breath quiet) from a forced one (face gripping, breath hurried) — so you fix the thing that actually needs fixing.
Reading the pattern is only half the job. The other half is knowing how to lead a student up from where they stand. And that road has one foundation common to everybody, whatever their level: draw the breath slower, longer, deeper, and above all breathe out longer than you breathe in. Which is exactly the next lesson.
