Eka Pada Sirsasana

Leg-behind-head postures are described among the more advanced hip-opening shapes associated with hatha demonstrations of physical mastery; they mark an extreme point on the spectrum of hip flexibility rather than being positioned as everyday practice postures in classical teaching.

• Deeply opens the hip socket and outer hip rotators of one leg at a time
• Stretches the hamstrings and groin intensely on the working side
• Builds core strength needed to keep the spine upright while the leg is hooked behind the head
• Prepares the body for more advanced leg-behind-head postures
• Develops patience and body awareness through slow, controlled hip opening

1. Sit with both legs extended, then bend one knee and draw that shin toward the chest.
2. Use the hands to guide the ankle up and over the same-side shoulder, rotating from the hip.
3. Settle the leg behind the neck, letting the shin rest across the back of the shoulders.
4. Keep the extended leg active on the floor, foot flexed.
5. Lift the chest and lengthen the spine rather than hunching around the lifted leg.
6. Bring the palms together at the chest once balance is found, if stability allows.
7. Release slowly by lifting the leg back over the head with the hands, then extend it back to the floor.

Pulling the leg with the arms alone — let the hip rotate open first through preparatory stretches, and use the arms only to guide, not force, the placement. Twisting through the knee — the rotation must originate at the hip joint, never by torquing the knee sideways. Collapsing the spine forward — keep lifting the chest so the pose doesn't become a slump. Attempting this without warm-up — the hip flexors and outer hip need to be warmed with poses like Pigeon or Gomukhasana first.

• Supported with strap: loop a strap around the foot and behind the neck while building flexibility
• Reclined version: practice lying on the back to reduce the demand on core stability while opening the hip
• Half version: keep the shin resting on the shoulder rather than fully behind the neck
• Advanced: progress toward Dvi Pada Sirsasana with both legs, or into Yoganidrasana

With one leg fixed behind the head, the torso must find a controlled, steady lift to keep breathing free despite the compression; teachers often describe this contained, effortful stillness as a practical training ground for calm concentration under physical difficulty.

This posture requires an exceptional degree of external hip rotation that most bodies do not have without years of progressive, targeted stretching; attempting it early risks strain to the hip capsule or knee. Gradual preparation through simpler hip openers, tracked over months, is the only evidence-consistent path toward this range of motion.
