Half Cobra Pose
Ardha Bhujaṅgāsana
A gentle prone backbend that strengthens the spine, opens the chest, and builds foundational back extension without compressing the lower back.
Half Cobra Pose, or Ardha Bhujaṅgāsana in Sanskrit ('ardha' meaning half, 'bhujaṅga' meaning serpent), is a gentle prone backbend that lifts only the upper chest off the mat. It commonly serves as an accessible prep pose or warm-up in Vinyasa and Hatha flows before deeper extensions like Full Cobra or Upward-Facing Dog. By keeping the hands light, this posture relies on back-body engagement rather than arm force to lengthen and awaken the spine.

Targets
Erector spinae, Rhomboids and middle trapezius, Gluteal muscles, Pectoralis major (lengthening)
Good for
awakening the postural back muscles, counteracting rounded desk posture, gentle spinal decompression
Breath
Inhale to draw the chest forward and up while anchoring the pelvis, and exhale to maintain gentle engagement through the core and legs.
How to do Half Cobra Pose
- 1Lie prone on your mat with your legs extended straight behind you, tops of the feet resting flat and hips-width apart.
- 2Place your palms flat on the floor beside your lower ribs, keeping your elbows bent and tucked close to the sides of your torso.
- 3Press the tops of your feet, thighs, and pubic bone firmly down into the floor to anchor your lower body.
- 4Inhale and roll your shoulders back and down, drawing your shoulder blades toward your spine to open the chest.
- 5Using the strength of your back rather than pushing with your hands, peel your head, neck, and upper chest slightly off the mat.
- 6Hover your hands an inch off the floor or keep just the fingertips lightly touching down to ensure your back muscles do the work.
- 7Keep your gaze directed softly toward the front edge of your mat so the back of your neck stays long and unwrinkled.
- 8Exhale to slowly lower your chest, collarbones, and forehead back down to the earth with control.
Benefits
- Strengthens the intrinsic muscles supporting the thoracic and lumbar spine.
- Expands the anterior chest and stretches the front shoulders.
- Encourages healthy blood circulation along the spinal column.
- Reinforces active glute and hamstring engagement to support safe backbends.
- Improves breath capacity by gently mobilizing the rib cage.
Common mistakes and cues
Pushing through the hands
Avoid pressing your palms into the floor to force height; rely solely on your spinal extensors to lift the chest.
Crunched neck
Keep your gaze cast down and slightly forward rather than cranking your chin upward and compressing cervical vertebrae.
Splaying the elbows
Hug your elbows firmly toward your ribcage rather than letting them flare out to the sides like wings.
Relaxed lower body
Prevent your legs from flopping loosely by actively anchoring the tops of your feet and engaging your thighs.
Modifications and props
Sphinx pose transition
Rest your forearms flat on the floor beneath your shoulders to reduce spinal load while still receiving chest-opening benefits.
Blanket under hips
Place a folded blanket beneath your pelvis and lower belly if your hip points feel tender pressing into the floor.
Wider leg stance
Separate your feet as wide as your mat to create more spaciousness in the sacrum and ease lower back tension.
Hands interlaced at low back
Interlace your fingers behind your sacrum to encourage deeper shoulder retraction without relying on floor contact.
Cautions
Acute lower back injuries
Skip active backbends or seek guidance if recovering from recent disc herniations or severe back spasms.
Late pregnancy
Avoid lying flat on your belly after the first trimester; practice gentle kneeling or standing heart openers instead.
Recent abdominal surgery
Allow full healing before putting pressure on the abdomen or stretching healing abdominal tissues.
If you are working with an injury, pregnancy or a medical condition, check with a qualified professional before practising this pose.
