Vasisthasana

Vasisthasana is named after the Vedic sage Vasistha but the arm-balancing posture itself is not described in the Hatha Yoga Pradipika or Gheranda Samhita; naming asanas after sages and deities was common practice in the twentieth-century systematisation of yoga postures. It should be understood as a modern pose carrying a classical name rather than a technique described in the older texts.

• Builds significant strength in the shoulders, wrists, and obliques
• Strengthens the outer hip and ankle of the standing leg
• Improves whole-body balance and core coordination
• Stretches the side body and, in the leg-lifted variation, the hamstrings
• Develops steadiness in an asymmetrical, effort-based hold

1. Begin in a plank position with the hands under the shoulders.
2. Shift weight onto the right hand and the outer edge of the right foot.
3. Stack the left foot on top of the right, or stagger it slightly forward for stability.
4. Rotate the torso open and extend the left arm straight up toward the ceiling.
5. Keep the hips lifted in line with the shoulders and ankles, resisting a sag.
6. Press firmly through the base hand and the outer standing foot to stay stable.
7. Optionally bend the top knee and hold the big toe for the full variation.
8. Hold for five breaths, then lower with control and repeat on the other side.

• Letting the hips sag toward the floor: engage the obliques and lift the hip points upward.
• Placing the base hand too far forward: stack it directly under the shoulder to protect the wrist.
• Collapsing into the base shoulder: press the floor away actively to keep the shoulder stable.
• Rushing into the full arm-balance variation: build the basic hold first before adding the leg lift.

• Easier: keep the bottom knee bent and resting on the floor for extra support.
• Easier: stagger the top foot slightly in front of the bottom foot rather than stacking it.
• Harder: lift the top leg and hold the big toe, extending the leg toward the ceiling.
• Harder: lower into a side plank push-up, bending and straightening the base arm.

As a strong lateral balance, Vasisthasana demands sustained engagement of the core and steady, even breathing rather than breath-holding, since the effort of the pose can easily tighten the chest. The pose is named for the sage Vasistha, and many teachers use the association to frame the hold as a practice in steady will and patience rather than raw strength alone.

Side-plank style holds like Vasisthasana are studied mainly in the context of core and shoulder strength training, where they reliably build isometric strength in the obliques, shoulders, and wrists. There is no research specific to this named yoga posture beyond its function as a strength-building position.
