Knees-to-Chest Pose

apana = the downward vital air

Written and reviewed by The Kriya Yogi · Updated 20 September 2026

Knees to chest — the simplest pose in yoga: lying back, hugging the knees, letting the lower back melt into the earth.

Family: Supine

The yogic view

Apana is the downward-moving energy — the current of elimination, grounding, and release — and this humble pose is named for it directly. The knees drawn to the chest compress the belly, massage the ascending and descending colon, and gather everything toward the centre and down. The classical physicians of the tradition prescribed exactly this shape after meals gone wrong and at the end of practice: the body balled small, the spine flat on the earth, the breath low and slow. It is the pose that teaches the nervous system the posture of safety.

How to practise

Lie on your back with the legs extended.
Draw one knee toward the chest and hold the shin; release and repeat with the other leg.
Then draw both knees in and wrap the arms around the shins.
Keep the tailbone and the back of the head resting on the floor; breathe into the belly.
Rock gently side to side if pleasant, and stay for one to three minutes.

For seated or floor-based work, use a clean, stable surface. Our natural cork yoga mat offers a grounded 5 mm surface for regular practice.

What research shows

Supine knee-to-chest flexion gently stretches the lower back and gluteal muscles and is among the most commonly recommended positions in physiotherapy for acute lower-back relief. The abdominal compression stimulates the vagus nerve and aids intestinal transit — small studies support the traditional use for bloating and gas. As a resting counterpose after backbends and twists it neutralises the spine without any load.

Questions about Apanasana

+ How long should you hold Apanasana?

Apanasana suits a longer, quieter hold: roughly one to three minutes, or five to eight slow breaths if you are moving in and out of it as part of a sequence. Where the posture is one-sided, practise both sides for the same length of time. Let the breath decide: if it becomes short, held or noisy, you have stayed too long or gone too deep.

+ Is Apanasana suitable for beginners?

Yes. Apanasana is a beginner-level posture in the supine family, and it is a reasonable shape to learn early. Reduce the range, use a wall or a cushion where balance or height helps, and hold it for fewer breaths at first. Read the cautions below before you begin, since "beginner-friendly" is not the same as "suitable for everyone".

+ What are the modifications for Apanasana?

Work with the shape rather than around it: reduce the range, shorten the lever by bending the nearest joint, and raise the floor toward you. Three adjustments apply to almost any posture: raise the hips on a folded blanket or cushion in seated work, bend the knees in anything that loads the back of the legs, and use a wall, chair or block to take weight and remove the fear of falling. A supported version practised often produces more change than a deep version practised rarely.

+ Who should avoid or modify Apanasana?

For Apanasana specifically: pregnancy (modify or avoid). More generally, modify or skip it if you have an acute injury or recent surgery in the area it loads, if you are pregnant and have not been given individual guidance, or if the shape produces sharp, pinching, radiating or electric sensation. Numbness, tingling or pain travelling down a limb is a nerve signal to stop and be assessed, not to breathe through. This page is educational and is not medical advice.

+ What should you practise before and after Apanasana?

Prepare with a few minutes of small, slow spinal movement and warm-up for whichever area the posture loads most. Release afterwards with Shavasana (Corpse Pose). Both lists are links on this page, and either can be shortened when time is limited — but do not skip preparation for a posture that loads a joint at end range.

+ What does Apanasana mean in Sanskrit?

Apanasana translates as knees-to-chest pose — apana = the downward vital air The name follows Sanskrit convention, but the posture itself is modern and is not described in the classical texts.
