Ardha navasana or half boat pose is a seated balancing posture that involves forward bend. Keeping the level of difficulty and amount of required strength in mind the pose lies in the intermediate level.
Ardha asana is performed in the supine position. It targets working the abdominal muscles, adductor muscles, and hip flexors. Besides these, it also involves the quadriceps, hamstrings, and spine.
Along with providing flexibility and strength to the body, it also strengthens and improves the mental health of the practitioner.
Ardha Navasana vs. Paripurna Navasana
In Sanskrit, ‘Ardha‘ refers to ‘half’, ‘Nava‘ means boat, and ‘asana‘ is ‘pose.’ This posture is named so as the body resembles a shape it seems like a half boat.
Paripurna Navasana or simply Navasana (boat pose) is an accomplished version of half boat pose which needs strong cores and thighs to hold the pose.
Physically the difference between two can be clearly noticed by the position of the body;
- In half boat pose, because of less strength in core muscles legs are raised off the ground comparably at a lower angle (30-35 degrees)
- In paripurna navasana, however, the legs are raised higher than the level of the head (60-65 degrees) so that there is a very little gap between the thighs and abdomen.
While holding the pose, the sit bones and tail bones are the only body parts touching the floor. The entire body is balanced between them with a straight spine. The arms and the lower leg are extended forward and are parallel to the ground. However, the knees are kept bent.

Iyengar’s description of Ardha navasana is quite different from the above steps. According to Iyengar procedure;
- In step 4, instead of bringing hands to knees level, hands with interlaced fingers are placed at the back of head and then lean back.
- Then legs are stretched straight forward and keep them stiff at an angle of 30 to 35 degrees.
Other steps of coming out of the pose is performed in the same manner.
