When you think of Paripurna Navasana (Boat Pose), you probably think of holding an abs-olutely core-crushing position. Yes, the pose does work your abdominal muscles. You’ll build the core strength required for inversions and arm balances like Crow or Firefly. And let’s face it: a strong core is key. It helps you stand taller, helps prevent injury, and makes you better at other activities like running or rock climbing.
But Boat Pose also strengthens your hip flexors, adductors (groin), and the lower back muscles that support your spine. It offers a mental test, as well. You need to dig deep in Navasana to extend, expand, and open your body while pushing through heat and discomfort. But it’s a pose with enough variations to allow you to find your way a fully extended pose. If you are working on building the core strength to hold the pose with your arms and legs outstretched, try holding on to your legs behind your knees. In time, you’ll find Boat Pose smooth sailing.

Try with your knees bent to lessen the effort and take pressure off your low back. Keep your arms extended in front of you, bring your palms to the backs of your thighs, or place your hands behind you on the floor for support.

Prepare to come into the pose but keep your feet on the ground. If you like, lift one leg at a time. You can keep the lifted leg bent or straighten it. Hold onto the back of your thighs for extra support or bring your hands behind you on the floor. Try transitioning back and forth between legs with your breath, switching legs on an exhalation.
Pose type: Seated
Targets: Core
Benefits: Boat Pose builds focus and body awareness. It can boost energy and fight fatigue, and can help build confidence and empowerment. It also improves posture and counteracts the effects of prolonged sitting and doing computer work by strengthening your core and thighs.
“I do Boat Pose incrementally with bent knees, holding the back of my legs,” says Sarah LaVigne, Yoga Journal‘s contributing photo editor. “Once I find my balance and am past the wobbly phase, I slowly straighten my legs. This step-by-step approach focuses me on each stage. Once I reach the peak pose, I feel like I am floating.”
These tips will help protect your students from injury and help them have the best experience of the pose:
Before undertaking Boat Pose, you want to stretch and challenge your body in the same manner demanded by this challenging pose. That means stretching your hamstrings and low back, engaging your abdominals, and lifting your chest without overarching your low back.
Adho Mukha Svanasana (Downward-Facing Dog Pose)
Uttanasana (Standing Forward Bend)
Padangusthasana (Big Toe Pose)
Baddha Konasana (Bound Angle Pose)
Bharadvajasana (Bharadvaja’s Twist)
Navasana is, technically, a forward fold since it flexes your body at the trunk. However, as anyone who has ever attempted Navasana knows, this pose is more of an isolated strengthening of your core and less a focused stretch. Unlike most forward bends, it requires constant muscular effort to maintain.
In the drawings below, pink muscles are stretching and blue muscles are contracting. The shade of the color represents the force of the stretch and the force of contraction. Darker = stronger.

When you contract the rectus abdominis at the front of your abdomen, you activate all the layers of the abdominals, including the transverse abdominis and the oblique abdominals. They work to flex your hips. But you also need to activate the psoas and its synergist hip flexors. The psoas, pectineus, sartorius, and rectus femoris muscles bend your hips and flex your trunk to lift your legs.
When your back rounds in Navasana, it means you are relying entirely on the abdominals and need to engage the hip flexors to tilt your pelvis forward. All of these actions are required to attain optimal alignment in this challenging pose.
To feel the psoas engage, bend your knees with your feet on the ground and place your hands on your thighs. Resist with the hands while you attempt to draw your knees toward your chest. Look for this same feeling while in the full expression of the pose. Or simply stay here and, as you gain strength, work toward the classic expression of the pose.

The trapezius muscles combine with the rhomboids (which connect the shoulder blade to the spine) to draw your shoulders back and down toward the midline of your body to open your chest. Once your scapulae are constrained in this fashion, you can contract the pectoralis minor, located under the pectoralis major on your chest, to lift and expand your rib cage and open your chest.
A cue for engaging these muscles is to hold the shoulder blades back and then attempt to roll the shoulders forward. The shoulders won’t move but the contractile force of the pectoralis minor and serratus anterior will be transmuted to your ribcage, lifting it upward.
The erector spinae and quadratus lumborum lift and slightly arch the back. The quadratus lumborum acts synergistically with the psoas major to support the lumbar spine.
Squeeze your knees toward one another to engage the adductors in your legs. Plantar flex the ankles and point your toes to stretch the tibialis anterior muscles and toe extensors. This activates the gastrocnemius and soleus muscles in the calf, which are attached to the heel by the Achilles tendon. The peroneus longus and brevis slightly evert your ankles and turn your feet slightly outward, opening the soles of your feet.

This is a great pose to build heat. Include it during the heat-building portion of class or as a respite from intense standing poses. Practice this posture in the beginning of class to fire up your core for the rest of your practice. Counter core work with gentle twists or backbends.
