Anantasana: A Complete Guide to Sleeping Vishnu Pose

Quick Intro

Anantasana (Sleeping Vishnu Pose in English) is a yoga exercise performed lying on one side, with the bottom arm supporting the head and the top leg lifted and gripped by the big toe, extending toward vertical while the torso balances on the side of the ribcage.

Equipment Needed

No equipment is needed for Anantasana. A yoga mat is optional for cushioning under the hip and elbow.

Why Anantasana Matters

The lifted leg’s back of the thigh (hamstrings, biceps femoris) and inner thigh (adductors) both lengthen against the pull of the gripping hand, while the side of the waist (obliques) and front of the hip (hip flexors, iliopsoas) work to keep the torso from rolling forward or back. The outer hip (gluteus medius) of the lifted leg stabilizes the leg’s position in the air, and the muscles along the spine (erector spinae) hold the torso in one long, uncurled line.

Flexibility is the main demand, with balance next from holding the side-lying position steady.

When to Do It

Anantasana works well anywhere in a session that already includes hip and hamstring work, since the side-lying position isolates a stretch that standing forward folds cannot reach in quite the same way. It also suits a wind-down sequence, where the low, still nature of the pose helps a session settle before final relaxation.

Anyone with a shoulder injury on the supporting side, or a recent hip replacement, should approach this pose cautiously or skip it, since the position asks the bottom shoulder to bear weight while the top hip works through a demanding range.

Getting Ready

A few rounds of gentle hip circles and a seated or standing hamstring stretch prepare the tissues this pose asks the most of. Lying on the side first without lifting the leg, just settling the hip stack and the head on the arm, previews the base position before the grip and lift are added.

Press the bottom foot into the floor’s edge for a stable anchor, and let the bottom hand fully support the head’s weight, so the neck can stay relaxed.

Step-by-Step Instructions

1. The recline. Lie on one side, legs stacked, bottom arm bent with the hand supporting the head.

2. The grip. Reach the top hand down and hook two fingers, or the whole hand, around the big toe of the top foot.

3. The lift. Straighten the top leg and draw it upward, stacking the hip directly on top of the bottom hip.

4. The stack. Keep the torso long, the bottom foot pressing into the floor’s edge for balance.

5. The release. Lower the leg with control and roll onto the back to rest before switching sides.

How Many, How Often

Anantasana is dosed by breath count, since a steady breath keeps the balance actively managed while the leg holds its height.

Keeping the top hip stacked over the bottom hip matters more here than how close the leg gets to vertical, since letting the hip roll back trades alignment for the appearance of a taller lift.

Modifications and Variations

Anantasana has both an easier entry and a considerably harder progression built directly on top of it.

For an easier entry point, Anantasana — Strap Assist loops a strap around the top foot instead of gripping the toe directly, letting the shoulder stay relaxed while the hamstring still lengthens toward vertical.

For more difficulty, Anantasana — Both Legs Lifted lifts the bottom leg off the floor as well, removing the stable anchor point and turning the pose into a two-leg balance challenge.

Progression path: Anantasana — Strap Assist → Anantasana → Anantasana — Both Legs Lifted

Common Mistakes to Avoid

Letting the top hip roll back instead of stacking over the bottom hip. This turns a controlled stretch into an unstable lean. Actively pressing the top hip forward, directly over the bottom one, keeps the torso in the alignment the pose depends on.

Straining the neck to hold the head up instead of resting it on the supporting arm. A tense neck spreads tightness through the whole upper body and makes the balance harder to hold. Letting the bicep or forearm fully bear the head’s weight removes that unnecessary tension.

Yanking the leg toward vertical. Forcing the range before the hamstring is ready shortens the breath and tightens the very muscle being stretched. A patient approach, breathing into the current range, produces more lasting flexibility than a single hard pull.

After Your Set

Rolling onto the back and hugging both knees to the chest releases the hip and lower back after the side-lying hold. A few slow breaths in this position settle the body before switching to the second side.

Going Deeper

This pose is usually trained by prioritizing a stacked hip position over raw leg height, letting the range increase naturally as the hamstring and hip open over time. The most common way it stalls isn’t hamstring tightness by itself, but a top hip that quietly rolls backward to fake a higher-looking lift, which trades away the balance and alignment work this pose is meant to build. Keeping that hip stacked every single session, regardless of how high the leg reaches, is what drives progress here.

Someone new to this pose generally holds a steady 5-breath side within the first two to three weeks, and reaches a settled 8-breath hold with the leg near vertical somewhere in the six to eight week range.

How to Know You’re Improving

1. A stable 3-breath hold with the leg at a comfortable height
2. A 5-breath hold with the hip staying stacked throughout
3. The leg reaching closer to vertical without the hip rolling back
4. A hold that feels roughly even on both sides

The hip staying stacked through the entire hold, not how high the leg travels, is the marker of progress here.

Muscles Worked

• Biceps Femoris (a muscle at the back of the thigh, stretched on the top leg as the toe is held)
• Adductors (the inner thigh muscles, lengthened as the raised leg reaches toward vertical)
• Obliques (the muscles along the sides of the waist, holding the body from rolling forward or back)
• Iliopsoas (the hip flexor group at the front of the hip, holding the top leg up against gravity)
• Gluteus Medius (a smaller glute muscle at the side of the hip, keeping the raised leg from drifting)
• Erector Spinae (the muscles running along the length of the spine, keeping the body in one line along the floor)

FAQ

Do I need to be able to touch my toes to try this pose? No, a strap around the foot works just as well as a direct hand grip, and either way the leg only needs to lift to a height that feels stable, not fully vertical, when starting out.

Why does my torso want to roll backward during this pose? The gripping arm’s pull naturally tugs the top shoulder and hip backward unless the torso actively resists it. Focusing on pressing the top hip forward, over the bottom hip, corrects this directly.

Is it normal for one side to feel noticeably tighter than the other? Yes, most people carry more tightness in one hip or hamstring, so an uneven hold between sides is common and simply reflects individual flexibility differences.

Can this pose be done without lying all the way down on a hard floor? Yes, a folded blanket or yoga mat under the hip and elbow makes the position considerably more comfortable without changing the stretch itself.
