Janu Sirsasana B

Janu Sirsasana B

AdvancedSeated FoundationsSeated

At a glance

A deeper variation on Janu Sirsasana, sitting on the heel of the bent leg rather than resting that foot against the inner thigh. This asks considerably more of the ankle and hip than the A variation, and it's worth teaching as a genuine progression rather than an interchangeable option.

Let the heel settle under you before you fold forward onto it.

Essence

Sitting directly on the heel changes the demand on the ankle joint significantly compared to the A variation, and that ankle position needs its own readiness, separate from whatever hip mobility the fold itself requires. Treating this as simply "Janu A but sit on your heel" undersells a real anatomical difference.

Intention

To fold forward over one extended leg while sitting on the heel of the bent leg, asking more of both the ankle and hip than the A variation.

What this pose develops

Physical

  • Ankle mobility under load
  • Hip external rotation
  • Hamstring length in the extended leg

Mental

  • Discernment about whether the ankle position is honestly available today
  • Patience with a pose that builds on a foundation established in an earlier, related shape

Teaching concepts

  • Screening ankle comfort before suggesting this variation over the A version
  • Recognizing that readiness for Janu A doesn't automatically mean readiness for this one

How to practise

  1. 1From Janu Sirsasana A, or a fresh seated position, bend one knee and tuck the heel underneath, sitting directly on it, positioned below the perineum.
  2. 2Extend the other leg straight ahead.
  3. 3Turn the torso to square toward the extended leg.
  4. 4On an inhale, lengthen the spine.
  5. 5On the exhale, fold forward over the extended leg.
  6. 6Hold for five breaths, gaze to the big toe, then transition to the second side.

Alignment exploration

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

  • Heel sits directly under the sitting bone, ankle in a really available range, not strained.
  • Torso squares toward the extended leg before folding.
  • Spine stays as long as possible through the fold.
  • Extended leg active, foot flexed.

Breath

Ujjayi breath, sustained through the hold, with particular attention paid if the ankle position itself is demanding enough to shorten the breath.

Teacher’s eye

Screen the ankle position before the fold. If sitting on the heel causes sharp discomfort rather than a stretch sensation, this variation isn't appropriate today, and returning to Janu Sirsasana A is the right substitute, not a lesser choice.

Student practice

Reflect after practising:

  • This is a genuine progression from Janu A, not an interchangeable alternative. If the heel position is uncomfortable, staying with the A variation is the better call.
  • Ankle discomfort here is worth taking seriously and adjusting for, unlike the more familiar muscular stretch sensations elsewhere in this family.

Common movement strategies

Rather than mistakes, you may notice:

  • Build ankle mobility separately over time if this position is consistently uncomfortable, rather than sitting on the heel through sharp discomfort in pursuit of the shape.

Modifications

  • Janu Sirsasana A as a complete substitute for anyone whose ankle isn't ready for this variation.

Completion check

  • Exit through the vinyasa transition into Janu Sirsasana C or the next pose in the sequence.
