Butterfly

Baddha Konasana (yin)

BeginnerYin FoundationsYin

At a glance

A seated hip and low back stretch, the soles of the feet together a comfortable distance in front of the pelvis, the spine rounding forward and releasing under gravity. It shares its starting shape with the active Bound Angle found in Seated Foundations, but the intention and the muscular quality here are entirely different.

Let gravity do the work, not your muscles.

Essence

The active version of this shape asks the spine to stay long and the muscles to hold a degree of engagement. This version asks for the opposite: a fully passive spine, rounding under its own weight, with no muscular effort holding anything in place. That passivity is what allows the sustained hold to reach the connective tissue this practice targets.

Intention

To release the hips and low back passively over a sustained hold, allowing gravity and time, rather than active effort, to create the stretch.

What this pose develops

Physical

  • Passive hip external rotation over sustained time
  • Connective tissue and fascial release around the hips and low back
  • A different quality of flexibility than active stretching produces

Mental

  • Sustained stillness over several minutes
  • Comfort with productive, moderate sensation held over time

Teaching concepts

  • Cueing genuine passivity, not held engagement, as the actual technique
  • Offering support generously so the spine can fully release rather than being held up by effort

How to practise

  1. 1Sit with the soles of the feet together, positioned a comfortable distance in front of the pelvis, further out than the active version of this shape.
  2. 2Let the knees release open without any effort to press them down.
  3. 3Round the spine forward, allowing gravity to draw the torso down over time.
  4. 4Rest the arms wherever they land, or support the torso on a bolster if using one.
  5. 5Settle in for three to five minutes, or longer, releasing any residual holding with each exhale.
  6. 6Come out slowly, rolling up one vertebra at a time.

Alignment exploration

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

  • Alignment here is looser than in active poses. The spine rounds fully, the muscles stay soft, and the main structural consideration is comfort over the sustained hold, not a specific shape to maintain.

Breath

A slow, natural breath, with no particular technique required. Each exhale can be an invitation to release a little further, though nothing should be forced.

Teacher’s eye

Watch for tension held in the shoulders, jaw, or hands, common signs a student hasn't fully let go even though the shape looks passive. A cue to soften those areas specifically often does more than any instruction about the fold itself.

Student practice

Reflect after practising:

  • This isn't the same pose as the active Bound Angle, even though it starts in a similar shape. Let your muscles go completely soft here.
  • Three to five minutes is a long time to hold anything. Expect your mind to wander, and gently bring it back to the sensation without judgment.

Common movement strategies

Rather than mistakes, you may notice:

  • Support the torso on a bolster or stacked blankets if the fold doesn't reach a comfortable resting point on its own, allowing genuine passive release rather than muscular holding.

Modifications

  • A bolster or stacked blankets supporting the torso.
  • Blocks under the outer knees if they hover uncomfortably high.
  • A cushion under the sitting bones for extra height.
