Half Moon

Ardha Chandrasana

IntermediateStanding FoundationsStanding

At a glance

A one-legged balance that opens the whole side of the body while the lifted leg reaches out behind. It's often taught as a triangle variation, but the balance demand changes the pose completely, and treating it as a triangle with a lifted leg tends to undersell how much standing-leg strength it really needs.

Root the standing leg before you kick the other one away.

Essence

Most wobbling in Half Moon comes from a standing leg that isn't actually pressing down, not from the lifted leg itself. Students focus their effort on the leg that's moving and neglect the one doing the real work of holding them up.

Intention

To build single-leg strength and stability while opening the hip and side body of the lifted leg.

What this pose develops

Physical

  • Standing leg strength and ankle stability
  • Hip opening in the lifted leg
  • Core engagement to keep the torso from collapsing forward

Mental

  • Composure in an exposed, off-center balance
  • Trust in a single point of contact with the floor

Teaching concepts

  • Cueing the standing leg's active pressing before anything about the lifted leg
  • Reading the torso for collapse toward the floor as fatigue sets in

How to practise

  1. 1From Triangle Pose or Warrior II, shift weight onto the front leg and bring the back foot in slightly.
  2. 2Place the lower hand on a block or the floor, roughly a foot in front of the standing foot.
  3. 3Bend the standing knee slightly as the back leg lifts, kicking the heel out and back.
  4. 4Straighten the standing leg as the lifted leg reaches to hip height, hips stacking vertically.
  5. 5Open the chest and reach the top arm straight up, or keep both hands down for more stability.
  6. 6Fix the gaze on a steady point, whether down, forward, or up.

Alignment exploration

Instead of searching for the “correct” position, notice:

  • Standing leg straight and active, knee tracking over the foot, not locked and passive.
  • Hips stacked vertically, top hip not rolling forward over the bottom one.
  • Lifted leg active, foot flexed, reaching out from the hip rather than just floating.
  • Supporting hand's shoulder stays away from the ear, not collapsing weight into the arm.

Breath

An even breath here is a direct readout of how much the standing leg is really working. If the breath is held or ragged, the leg has probably locked up rather than staying actively engaged.

Teacher’s eye

Track the standing leg's knee. A wobble that starts there, rather than at the hips, usually means the leg has gone passive, locked straight without any active press into the floor. Cueing "press the standing foot down" is often more effective here than any adjustment to the lifted leg or the arms.

Student practice

Reflect after practising:

  • The lower hand is a kickstand, not a crutch. Try to feel how little weight it truly needs to hold.
  • If the hip of the lifted leg is rolling forward, opening the chest more can help square things back out.

Common movement strategies

Rather than mistakes, you may notice:

  • Practice near a wall, back body lightly touching it, to feel what a vertically stacked hip position actually is.
  • Build standing leg strength separately in Tree Pose or single-leg deadlift-style movements before adding the reach and lift of Half Moon.

Modifications

  • Hand on a block instead of the floor, at whatever height keeps the shoulder relaxed.
  • Back against a wall for balance and postural feedback while the standing leg strength develops.
  • Top hand on the hip instead of reaching up, for more stability.

Completion check

  • Bend the standing knee and lower the lifted leg back to the floor with control, returning to Triangle or standing. Pause before the second side.
