Pilates Breathing:
Lateral Breathing Explained

1. Find the ribs with your hands

Sit or lie with knees bent. Place your hands on the sides of your lower ribcage, thumbs pointing back, fingers wrapping around the front. Breathe in and try to widen your hands apart without letting the belly push forward or the chest lift toward the chin. Most people feel almost nothing on the first few attempts — the movement is a couple of centimetres, not a dramatic expansion.

2. Add a band for feedback

Wrap a light resistance band or a long scarf around the lower ribs, crossed at the front, held with light tension. Now you are breathing into something. The resistance gives your nervous system a target, and this is the step where the pattern usually clicks for people who could not feel it with hands alone. Ten breaths.

3. Lengthen the exhale

Inhale for a count of three, exhale for a count of five or six through slightly pursed lips. The long exhale is where the deep abdominals and pelvic floor engage automatically — you do not need to consciously pull anything in. Feel the ribs draw down and together at the end of the exhale. That closing action is the position from which the next breath should start.

4. Attach it to movement

Only once the pattern is comfortable at rest should you add exercises. Start with something simple — knee folds, pelvic tilts, a small bridge — exhaling on the effort. Expect the pattern to fall apart the moment the exercise becomes demanding. That is normal, and the fix is to regress the exercise rather than abandon the breath.

The Hundred

Five short pumps on the inhale, five on the exhale, ten cycles. The percussive breath is the exercise as much as the arm beat is — it is a deliberate challenge to maintain abdominal engagement while breathing rhythmically under load. If you find yourself holding the breath and pumping the arms, stop and restart at a slower tempo.

Roll-up

Inhale to prepare and lengthen the spine, exhale through the whole articulation up. The long exhale is what allows the lumbar spine to flex segmentally instead of lifting as a rigid block. Inhale at the top, exhale to roll down. This is the exercise where breath most obviously determines whether the movement is possible.

Single leg stretch and the abdominal series

Exhale on each change of leg, or exhale across two changes if the pace is quick. The exhale coincides with the moment of greatest demand on the deep abdominals, which is exactly when you want them recruited.

Spine stretch forward

Inhale to sit tall and lengthen, exhale to curl forward over the legs. The exhale draws the ribs down and lets the thoracic spine flex properly rather than the movement coming from the hips.

Bridge / shoulder bridge

Exhale to roll the pelvis up, inhale at the top, exhale to roll down vertebra by vertebra. Slower than most people do it — the point is the segmental articulation, and a long exhale is what paces it.

Swan and extension work

This is where classical and contemporary schools differ. Contemporary practice usually exhales into the lift for abdominal support. Classical practice often inhales into extension, using the breath to expand the chest and assist the shape. Both are defensible; follow whichever your instructor cues rather than fighting the room.

What is lateral breathing in Pilates?

Lateral breathing — also called intercostal or ribcage breathing — directs the inhale sideways and backwards into the lower ribs rather than forwards into the abdomen. The ribs widen laterally like a bellows while the abdominal wall stays gently drawn in. The diaphragm still descends and does the same work it always does; what changes is where the expansion is allowed to show. This lets you maintain abdominal engagement continuously while still breathing fully, which is why the method uses it.

Do you breathe in through the nose or mouth in Pilates?

The convention is to inhale through the nose and exhale through the mouth, and it is a practical convention rather than a rule. Nasal inhalation filters and slows the breath and encourages a fuller lateral expansion. Exhaling through the mouth — often through slightly pursed lips, sometimes with an audible sound — encourages a longer, more complete exhale, which is what recruits the deep abdominals. If a blocked nose makes nasal breathing impractical, mouth breathing throughout is fine and will not undermine the exercise.

Why do I get dizzy or lightheaded during Pilates breathing?

Almost always over-breathing — inhaling harder and more often than needed while concentrating on the pattern, which lowers carbon dioxide levels and produces lightheadedness. The fix is to make the exhale longer than the inhale and let the breath stay quiet rather than forceful. Breath-holding, which is the other common cause, produces the same sensation on release. If lightheadedness persists once your breathing has settled, stop the session and get it checked rather than pushing through it.

When should I inhale and exhale in Pilates?

The general rule in contemporary Pilates is to exhale on the effort — the flexion, the lift, the moment of greatest abdominal demand — and inhale on the return or preparation. Exhaling naturally recruits the deep abdominal wall and pelvic floor, so it supports the spine exactly when support is most needed. Classical Pilates sometimes reverses this deliberately, notably inhaling into spinal extension. Both are legitimate; what matters far more than the direction is that you keep breathing rather than holding.
