Half Boat Pose
Ardha Navasana · अर्ध नावसन
Also known as: Half Navasana · Low Boat Pose
Half Boat Pose, also called Half Navasana is a classical yoga posture. Its Sanskrit name Ardha Navasana translates word-for-word as: Ardha (Half) · Nava (Boat) · Asana (Pose). Performed lying down, the body releases into the support of the floor, allowing gravity to assist. The posture works to engage the core. Tones the hip flexors and lower back. Builds core endurance for advanced postures. It is particularly valued for building full-body strength and improving overall posture. Suitable for intermediate practitioners with foundational yoga experience, it is an excellent warm-up, particularly beneficial for beginners and teens. A strap and blanket can be used to make the posture more accessible and support correct alignment. Practitioners with abdominal surgery and pregnancy should approach with care or consult a qualified teacher.
Anatomy Involved
Benefits
Rectus Abdominis(strengthening)
The superficial 'six-pack' muscles, running vertically from your ribs to your pelvis, are intensely engaged here, particularly the lower fibers. As you draw your navel towards your spine and maintain the rounded shape, these muscles contract concentrically to flex the trunk, bringing the rib cage closer to the pelvis. This action builds tremendous heat and core power, cultivating a feeling of grounded strength and resilience in the body's center.
Transverse Abdominis(stabilizing)
This deepest layer of abdominal muscle acts like a natural corset, wrapping horizontally around your midsection from front to back. In Ardha Navasana, it contracts deeply to stabilize the lumbar spine and pelvis, preventing excessive strain and creating a firm foundation for the pose. This subtle engagement brings a profound sense of inner support and containment, allowing prana to gather and focus in the abdominal region without dispersion.
Hip Flexors(strengthening)
The powerful muscles at the front of your hips, connecting your spine and pelvis to your thigh bones, work tirelessly to lift and hold your legs in this hovering position. The iliopsoas (iliacus and psoas major) is particularly active, flexing the hip joint and maintaining the elevation of the legs against gravity. This sustained effort builds endurance and strength in a crucial area often tight from sitting, releasing stagnant energy and invigorating the lower body.

Avoid If
Back Injury / Back Pain
Spinal flexion, extension, or rotation under load can compress vertebral discs or strain the paraspinal muscles.
Bend the knees and place feet flat on the floor to protect the lumbar spine; slide a folded blanket under the lower back if needed.
Pregnancy
Deep twists, abdominal compression, and lying flat on the back can restrict blood flow or cause discomfort as pregnancy progresses.
After the first trimester, avoid lying flat on the back; elevate the torso on a bolster or lie on the left side instead.
Recent Surgery
Surgical wounds and healing tissues need time before being subjected to the mechanical stress of yoga postures.
Wait for full medical clearance from your surgeon; begin with gentle breath work and progress only as healing allows.
Asthma
Vigorous effort and deep chest compression can trigger bronchospasm in those with reactive airways.
Keep effort mild, breathe through the nose, and have your inhaler within reach.
Props That Can Help
Optional supports — use when helpful, not required
Yoga Strap
Use a strap around the raised foot to control the leg extension without gripping or over-pulling, keeping the hip and sacrum stable.
Folded Blanket
A blanket under the head and neck maintains the natural cervical curve; under the knees, it relieves lower back tension in Savasana.
