Summary

A side-lying rotational movement that explores breath, rib mobility and ease through the upper back, chest and shoulders.

Lie on your side. Let the ribs turn. Follow the breath.

Essence

Open-Book Twist is a gentle way to explore rotation without needing to hold the body upright. The floor offers support, while the shape reveals how the ribs, spine, shoulders and breath relate to one another. It is less about reaching the floor and more about listening to the pathway of turning.

Intention

The purpose is not to make the top shoulder touch the ground. The purpose is to notice how rotation moves through the body when the hips are quiet, the breath is steady and the head can follow without strain.

What this pose develops

Physical

  • Thoracic rotation
  • Rib awareness
  • Shoulder mobility
  • Chest opening

Mental

  • Patience
  • Curiosity
  • Sensory awareness

Teaching concepts

  • Supported rotation
  • Breath-led movement
  • Differentiating ribs and pelvis

How to practise

  1. 1Lie on one side with your knees bent.
  2. 2Stack the knees and let them rest in front of the hips.
  3. 3Reach both arms forward at shoulder height.
  4. 4Rest the lower arm on the floor.
  5. 5Inhale and lengthen gently through the top arm.
  6. 6Exhale and allow the top arm to open away from the lower arm.
  7. 7Let the ribs and head turn if this feels comfortable.
  8. 8Pause where the breath remains easy.
  9. 9Return slowly and repeat before changing sides.

Alignment exploration

Instead of searching for the “correct” position, notice:

  • Do the knees stay quiet as the ribs turn?
  • Is the movement coming from the upper back or only the shoulder?
  • Can the head follow without pulling?
  • Does the breath change as the chest opens?

Breath

Let the breath guide the range. The inhale may create a sense of space across the ribs. The exhale may allow the body to settle into the turn. If breathing becomes sharp or held, explore a smaller arc.

Teacher’s eye

Observe whether the student rotates through the ribs or lets the pelvis roll back. Notice the relationship between the top arm, the chest and the breath. A smaller movement may show more clarity than a larger shape.

Student practice

Reflect after practising:

  • Where did the turn begin?
  • Did one side feel more spacious than the other?
  • What happened when you moved more slowly?
  • Could your breath stay present throughout the movement?

Common movement strategies

Rather than mistakes, you may notice:

  • Rolling the pelvis backwards
  • Forcing the top shoulder towards the floor
  • Letting the knees separate
  • Pulling with the neck
  • Holding the breath

Modifications

  • Place a cushion between the knees
  • Support the head with a folded blanket
  • Keep the top hand on the ribs
  • Open only halfway
  • Move dynamically rather than holding

Completion check

  • The body returns easily to the side-lying start.
  • Breathing remains comfortable.
  • The knees and pelvis feel settled.
  • The turn feels spacious rather than forced.
