Yoganidrasana: The Yoga Pose for Both Legs Behind Head, Preparation, and Safety

What is the yoga pose called for both legs behind head?

The yoga pose most commonly referred to when both legs are placed behind the head, particularly in a supine position, is Yoganidrasana, often translated as "Yogic Sleep Pose" or "Yoga Nidra Pose." This advanced asana demands extreme flexibility in the hips, hamstrings, and spine.

Understanding "Legs Behind Head" Poses

While the phrase "legs behind head" immediately brings to mind a challenging feat of flexibility, it encompasses a family of advanced yoga postures. The most direct answer, especially when the practitioner is lying on their back, is Yoganidrasana.

• The Primary Pose: Yoganidrasana (Yogic Sleep Pose)

  • In Yoganidrasana, the practitioner lies supine (on their back), and both legs are brought up and over the head, with the feet crossing behind the neck or even resting on the floor beyond the head. The arms often wrap around the legs, or the hands may interlace behind the back, further deepening the posture. This pose requires significant external rotation and abduction of the hips, alongside deep hamstring and spinal flexibility.

• Other Related and Advanced Poses

  • Dwi Pada Viparita Dandasana (Two-Legged Inverted Staff Pose): While not precisely "legs behind head" in the same supine manner as Yoganidrasana, this inverted backbend can bring the feet close to or even touch the head, especially in its deepest variations. It emphasizes spinal extension and shoulder flexibility.
  • Eka Pada Sirsasana (Foot-to-Head Pose): This is a preparatory pose for many "legs behind head" postures, involving bringing one foot behind the head. It builds the necessary hip mobility and hamstring flexibility.
  • Karandavasana (Himalayan Duck Pose): An advanced arm balance that combines an inversion with the "legs behind head" configuration, often with the legs in a lotus-like position behind the arms, demanding immense core strength, arm balance, and hip flexibility.

Anatomical Demands and Benefits

Achieving "legs behind head" poses requires a profound level of flexibility and strength. Understanding the anatomical prerequisites is crucial for safe and effective progression.

• Key Muscle Groups Stretched

  • Hamstrings: Crucial for allowing the legs to extend upwards and over the head.
  • Gluteal Muscles (especially Gluteus Maximus) and Hip External Rotators: Essential for the deep external rotation and abduction of the hips required to bring the knees wide and the feet behind the head.
  • Adductors: Stretched when the legs are wide.
  • Spinal Erectors and Latissimus Dorsi: Stretched in variations that involve spinal flexion (rounding the back) or when the arms wrap around the legs.
  • Shoulders and Neck: Require flexibility, especially in Yoganidrasana, to comfortably accommodate the legs.

• Joint Mobility Required

  • Hip Joints: Demand exceptional range of motion in flexion, abduction, and external rotation. The hip capsule must be supple.
  • Sacroiliac (SI) Joint: Requires stability and healthy mobility.
  • Spine: Needs significant flexion (especially in the lumbar and thoracic regions) to create space for the legs behind the head in Yoganidrasana.

• Potential Benefits

  • Enhanced Flexibility: Dramatically increases flexibility in the hips, hamstrings, and spine.
  • Improved Posture: By releasing tension in the posterior chain.
  • Stress Reduction: The deep stretching and inward focus can promote relaxation.
  • Stimulation of Organs: Gentle compression of the abdominal organs is believed to aid digestion.
  • Increased Body Awareness: Cultivates a deeper understanding of one's physical limits and capabilities.

Preparation and Progression

Approaching "legs behind head" poses should be a gradual, mindful journey, built upon a foundation of preparatory postures. Rushing into these poses can lead to injury.

• Foundational Poses for Hip and Hamstring Flexibility

  • Supine Hand-to-Big-Toe Pose (Supta Padangusthasana): Excellent for hamstring and inner thigh flexibility.
  • Happy Baby Pose (Ananda Balasana): Opens the hips and lengthens the inner groin.
  • Pigeon Pose (Eka Pada Rajakapotasana): Deep hip opener, focusing on external rotation.
  • Head-to-Knee Pose (Janu Sirsasana): Stretches hamstrings and hips.
  • Cow Face Pose (Gomukhasana): Targets hip external rotation and abduction.
  • Single Leg Behind Head Pose (Eka Pada Sirsasana): The direct precursor, building one-sided flexibility.

• Building Core Strength and Spinal Flexibility

  • Strong core muscles protect the spine and assist in maintaining stability.
  • Spinal mobility, particularly in flexion, is crucial for Yoganidrasana. Cat-Cow, seated forward folds, and gentle spinal twists can help.

• Importance of Warm-up

  • Always begin with a thorough warm-up to prepare muscles and joints. Sun Salutations, dynamic stretches, and holding preparatory poses for longer durations are highly recommended.

Step-by-Step Approach (Yoganidrasana - Simplified Description)

While detailed instruction requires a qualified teacher, here's a simplified overview of how Yoganidrasana is typically approached.

1. Start Supine: Lie on your back with knees bent, feet flat on the floor.
2. Lift Legs: Bring both knees towards your chest.
3. Open Hips: Use your hands to guide your knees wide, bringing them towards your armpits.
4. One Leg at a Time: Carefully bring one foot up and over your head, aiming to hook the ankle or calf behind your neck. You may need to lift your head slightly.
5. Second Leg: Repeat with the second leg. This is the most challenging step, requiring significant hip flexibility. The feet will ideally cross behind the head.
6. Deepen the Pose: Once both legs are behind the head, release your hands. You may keep your arms extended to the sides, or for a deeper variation, wrap your arms around your legs, or interlace your fingers behind your back.
7. Hold and Release: Breathe deeply and hold for a comfortable duration, then carefully release one leg at a time, slowly returning to a supine position.

• Modifications and Props:
  • Blanket under Head/Neck: Provides support and cushioning.
  • Strap: Can be used to extend the reach if the feet don't easily go behind the head.
  • Focus on One Leg: Practice Eka Pada Sirsasana extensively before attempting both.

Risks, Contraindications, and Safety Considerations

These advanced poses are not suitable for everyone and carry inherent risks if performed incorrectly or without adequate preparation.

• Common Risks

  • Hamstring Tears: Due to overstretching.
  • Knee Injury: Strain on the knee ligaments, particularly if the hips are not open enough.
  • Lower Back Strain: If the spine is not adequately prepared or core engagement is lacking.
  • Neck Strain/Injury: If the neck is forced or unsupported.

• Contraindications

  • Existing Injuries: Especially to the hips, knees, hamstrings, or spine.
  • Pregnancy: Deep abdominal compression and extreme stretches are generally contraindicated.
  • High Blood Pressure or Glaucoma: Inverted variations (like Karandavasana) might be unsuitable.
  • Sciatica: May exacerbate symptoms.

• Importance of a Qualified Instructor

  • Never attempt "legs behind head" poses without the guidance of an experienced and certified yoga instructor who can provide personalized adjustments and ensure proper alignment.

• Listen to Your Body

  • Pain is a signal to stop. Always respect your body's current limits and avoid pushing into discomfort or sharp pain. Progression should be gradual and pain-free.

Conclusion: A Journey of Patience and Practice

Yoganidrasana and other "legs behind head" poses represent pinnacles of flexibility and dedication within yoga. While visually striking, their true value lies in the journey of patience, consistent practice, and the profound body awareness cultivated along the way. Approach these advanced asanas with respect, a solid foundation, and the guidance of an expert, transforming a seemingly impossible feat into a testament to the body's remarkable potential.
