Naukasana: Boat Pose for Core Strength

Yoga poses 4 illustrations Updated 2 Nov 2026

Naukasana, the boat pose, is a seated balance in which you lean back on the sit bones and lift the legs, so the body forms a V like the hull of a boat. Nauka means boat. It is one of the best known core strengtheners in yoga and works the deep abdominal muscles, hip flexors and back muscles together. In many texts the same shape is called navasana or paripurna navasana, the full boat.

Here you will find three levels of the pose so every beginner can start, the breathing and alignment, frequent errors, what the pose builds, and when strong core work is a bad idea. Indian school syllabuses also describe a version lying on the belly, explained below.

Sanskrit: Naukasana (nauka: boat); navasana
English: Boat pose
Level: Beginner to intermediate
Hold: 3 to 5 breaths, 3 rounds
Works: Abdominals, hip flexors, back
Skip if: Pregnancy, recent belly surgery, hernia

How to do naukasana

Sit with the knees bent and feet flat, hands behind the thighs.
Lift the chest and lean back slightly until you balance on the sit bones.
Raise the feet so the shins are parallel to the floor.
If steady, release the hands and reach the arms forward.
To go further, straighten the legs, keeping the chest open.
Breathe steadily for three to five breaths.
Lower the feet, rest, and repeat two more rounds.

Back muscles
The prone version, lying face down and lifting the arms and legs, is taught in some schools as naukasana too.
**Teacher's cue:** Reach long through fingers and toes rather than lifting high.

Low boat with legs and shoulders hovering just above the floor between full boat rounds — Level
Intermediate
Hold
5 slow rounds

Core endurance
Moving between full boat and a low hover a few times builds strength once the held pose feels easy.
**Teacher's cue:** Drop toward the mat just to the point where you still feel in charge.

Three levels of boat pose

Level	Shape	Who it suits
One	Toes on the floor, hands behind thighs, chest lifted	New to core work
Two	Shins parallel to floor, arms forward	Most beginners after a few weeks
Three	Legs straight, arms forward	Strong core and flexible hamstrings

Stay at the level where you can keep the spine long. A rounded back at level three is less useful than a tall back at level one.

Common mistakes

Collapsing the chest: the lower back takes the strain. Bend the knees more.
Holding the breath: count breaths aloud if needed.
Gripping the neck: keep the chin slightly tucked and the throat soft.
Too many reps: three good rounds beat ten shaky ones.

Naukasana benefits

Strengthens the deep abdominal muscles and hip flexors.
Builds the back muscles that keep you upright.
Improves balance and body awareness.
Pairs well with other core work for posture and lower back support.

People add it to belly fat plans, yet spot reduction does not happen; the overall routine and diet do that.

The prone naukasana

Many Indian school charts teach naukasana lying on the stomach: arms forward, then lift the arms, head, chest and legs together so the body curves like a boat. It strengthens the back muscles, similar to locust pose. Both versions are useful; practise the seated boat for the front of the core and the prone boat for the back. Follow either with child pose.

Who should skip it

Avoid strong boat pose during pregnancy, after abdominal surgery, with a hernia, diastasis recti, a herniated disc or acute lower back pain, and with high blood pressure if you tend to hold the breath. If the hip flexors cramp, rest and stretch them in a low lunge, or swap in bridge pose for a gentler core session. Ask a doctor or physiotherapist if back pain flares after core work.

Names you might see

Naukasana yoga, naukasana yoga pose, boat pose yoga, boat pose in yoga, navasana yoga and navasana boat pose yoga are all used. Ardha navasana, the half boat, usually means the version with the hands behind the head and the body lower to the floor.

Practise on an empty stomach, move slowly into each position and stop at any sharp pain. If you have an injury, a health condition or are pregnant, check with a doctor or an experienced teacher first.
