Uddiyana Bandha

The abdominal lift. Uddiyana means flying up, which is a fair description of what happens to the diaphragm.

What it looks like

On a full exhale, with the breath held out, the abdominal wall draws back towards the spine and up under the ribcage. A visible hollow appears beneath the ribs. The lower ribs flare slightly outward.

The abdominal muscles are not what creates the hollow. What creates it is a false inhale — you expand the ribcage as though inhaling, but the throat is closed, so no air enters. The expanding ribcage creates a vacuum, and the vacuum draws the diaphragm and the abdominal contents upward. The abdominal wall relaxes and is pulled back by the pressure difference.

That is the mechanism, and knowing it changes the practice completely. Most people try to suck the belly in with muscular effort and get a poor version. The correct version is largely passive in the abdomen.

How to do it

Empty stomach. Four hours after a substantial meal, two after anything. This is not optional — the practice moves the abdominal contents and doing it on a full stomach is genuinely unpleasant.

Best done first thing in the morning, before eating and after using the bathroom.

Standing version, which is easiest to learn:

1. Stand with the feet hip-width, knees slightly bent, hands on the thighs just above the knees. Lean forward slightly so the arms take some of your weight.
2. Inhale fully.
3. Exhale completely. All of it. Then push a little more out. The completeness of the exhale determines everything that follows.
4. Close the throat — the same action as jalandhara bandha, chin drawing towards the sternum — so no air can enter.
5. Now expand your ribcage as if inhaling. Widen the ribs, lift the chest. Do not let air in.
6. The belly will draw back and up on its own. Do not pull it in with your muscles; let the vacuum do it.
7. Hold for five to ten seconds at first.
8. To release: first relax the ribcage and let the belly come back down. Then release the throat and let the inhale come in. Releasing the throat first, with the vacuum still present, produces a sudden gasp and it is unpleasant.
9. Take two or three normal breaths before the next repetition.

Three to five repetitions. That is a session.

Seated version: the same, sitting cross-legged with hands on the knees, once the standing version is reliable. Harder, because the arms are not helping.

What it should and should not feel like

Should: a strong vacuum sensation under the ribs. A stretch through the diaphragm and the front of the abdomen. Slightly odd the first few times.

Should not: strain in the throat, pressure in the head or eyes, a pounding heartbeat, or panic. Any of those means you are holding too long or the throat is not properly closed.

If you feel pressure behind the eyes or in the ears, stop, and check that the throat lock is engaged. Pressure escaping upward means the seal is not there.

The three errors

1. Incomplete exhale. The most common, and the reason people cannot get a hollow. If any air remains, the diaphragm cannot rise. Empty completely, then push out more.

2. Sucking the belly in muscularly. Produces a small, effortful, disappointing version. The abdominal wall should be soft. It is the ribcage that does the work.

3. Holding too long. Five to ten seconds is plenty at first. Building to twenty over months is reasonable. Longer is not better and increases the risk of light-headedness.

Why it is taught after the breath

Because it requires three things you should already have: a complete exhale, a reliable throat lock, and enough comfort with breath retention that holding out for ten seconds does not trigger alarm.

Attempting it before those exist produces panic and a bad association. The sequence is: breath awareness, then ratio work, then short retentions, then jalandhara, then this.

What it is for

Diaphragm mobility. The diaphragm is a muscle and it has a range of motion, and almost nothing else in ordinary life moves it through its full range. This does.

Abdominal and organ mobility. The traditional claim, and mechanically plausible — the pressure change moves the abdominal contents in a way nothing else does.

Control. It teaches an unusual degree of separation between the ribcage, the diaphragm and the abdominal wall, which transfers to everything else you do with the breath.

Preparation. It precedes work with longer retentions in most traditional sequences.

When not to

Skip this practice entirely if:

• Pregnant.
• Menstruating — traditionally omitted.
• Uncontrolled high blood pressure, or a heart condition.
• Hernia, of any abdominal kind.
• Ulcers or active digestive illness.
• Recent abdominal or pelvic surgery.
• Glaucoma or retinal problems.
• Recently eaten.

This is a practice with real contraindications, not a cautious list. If you are unsure, ask someone qualified before starting, and learn it with a teacher if you can.

The working version

Separate from all of the above: when a teacher cues "engage uddiyana" during asana, they do not mean this. They mean a light, continuous drawing back of the lower abdominal wall towards the spine, maintained while breathing normally, at perhaps twenty percent effort.

That version is safe, useful, and appropriate during practice. The full version described here is a discrete exercise done on its own.
