At a glance

An intense seated hip release, one shin stacked directly over the other, flexed feet, folding forward over the stack. It asks for more outer hip range than Shoelace, and it's one of the more demanding hip openers in this family, deserving real patience and generous support.

“Let the shins stack as closely as the hips honestly allow, then settle.”

Essence

Very few bodies stack the shins perfectly flat, and that's a matter of hip anatomy, not effort or practice. A gap between the shin and the opposite knee, supported rather than forced closed, is a genuine and complete version of this pose, not a lesser one.

Intention

To release the outer hips deeply through a stacked-shin position, folding forward as the hips allow.

What this pose develops

Physical

  • •Deep passive outer hip release
  • •Connective tissue release around the hip joint
  • •Ankle dorsiflexion from the flexed feet

Mental

  • •Sustained stillness in a demanding, often intense position
  • •Genuine acceptance of a gap in the stack, rather than treating it as failure

Teaching concepts

  • •Offering support under the top knee generously and by default
  • •Cueing the flexed feet, a detail that protects the knees under this stacked position

How to practise

  1. 1Sit with the legs extended, then stack one shin directly over the other, knee over ankle as closely as available.
  2. 2Flex both feet actively, protecting the knees.
  3. 3Hinge forward from the hips, letting the spine round as the torso lowers.
  4. 4Rest the hands, forearms, or a support wherever they land.
  5. 5Settle in for three to five minutes, then unstack slowly and repeat with the legs reversed.

Alignment exploration

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

  • •Feet stay flexed throughout, an active protection for the knees in this stacked position.
  • •The shins stack as closely as the hips honestly allow, with support under any resulting gap.
  • •The fold happens from the hips, spine rounding freely.

Breath

A slow, natural breath, with each exhale offering a chance to release a little further into the stretch.

Teacher’s eye

Notice whether the feet are staying actively flexed. That detail protects the knees in this demanding stacked position, and it's worth checking throughout the hold, not just at the start.

Student practice

Reflect after practising:

  • •A gap between your shin and the opposite knee is normal hip anatomy, not a flexibility failure. Support that gap rather than forcing it closed.
  • •Keep both feet actively flexed. That's protecting your knees in this position.

Common movement strategies

Rather than mistakes, you may notice:

  • •Support the top knee generously with a block by default, treating that support as the standard setup rather than something to eventually remove.

Modifications

  • •A block or two under the top knee.
  • •A smaller stack, more like a simple cross, for anyone with less available hip range.
  • •A bolster to fold over for additional support.
