Head-to-Knee Pose

Janu Sirsasana

Janu Sirsasana stretches one leg at a time, which many people find more accessible than a two-legged fold.

Focus

Single-leg hamstring stretch

Why practise it

Stretches the hamstrings and calf of the straight leg, the inner thigh of the bent leg and the back of the body. Because it works one leg at a time, many people find it more approachable than folding over both legs. Forward folds like this are often described as calming, though that is a common experience rather than a proven effect.

Head-to-Knee Pose: what to know

The name is not the goal

Despite the name, the head does not need to reach the knee. Folding from the hips with a long spine stretches the hamstring far more usefully than rounding the back to bring the forehead down. Sitting on a folded blanket tilts the pelvis forward and makes this much easier, especially with tight hamstrings.

How to do Head-to-Knee Pose

  • Sit in Staff Pose with both legs straight, on a folded blanket if the lower back rounds
  • Bend the right knee and place the sole of the right foot against the inner left thigh
  • Let the right knee drop out to the side; support it with a block or cushion if it does not reach the floor
  • Turn the chest slightly towards the straight left leg and lengthen the spine as you breathe in
  • Breathing out, fold forward from the hips, holding the shin, foot or a strap around the foot
  • Hold for 5 to 10 breaths, come up slowly and switch sides

Head-to-Knee vs Seated Forward Fold

  • Head-to-Knee (Janu Sirsasana): one leg bent, so one hamstring is stretched at a time with a slight twist towards the straight leg
  • Seated Forward Fold (Paschimottanasana): both legs straight, a deeper and more symmetrical stretch
  • Seated Wide Angle (Upavistha Konasana): legs wide, adding the inner thighs

Making it work for you

Bend the straight knee slightly if the hamstring pulls sharply or the back of the knee aches. Loop a strap around the foot rather than straining to reach it. Support the bent knee if it hurts, or place the foot lower on the shin rather than high on the thigh. Ease off with a hamstring or lower-back injury.

Alignment

Cues & common mistakes

Aim for Torso centred over the straight leg; straight-leg kneecap pointing up.

Teacher’s cues

Questions

What is Janu Sirsasana good for?

Stretching the hamstrings, calves and inner thighs one side at a time, and mobilising the back of the body.

Do I have to touch my head to my knee?

No. Fold from the hips with a long spine; how far you go depends on your hamstrings, not effort.

How long should I hold Head-to-Knee Pose?

5 to 10 breaths per side, or 1 to 3 minutes in a slower or Yin-style practice.

Why does my bent knee hurt?

It may be hanging unsupported or twisting. Place a block under it or move the foot lower down the leg.

Is Head-to-Knee easier than Seated Forward Fold?

For many people, yes. Working one leg at a time usually allows a longer spine and a more even stretch.

In the tradition

Janu means knee, sirsa head; part of the Ashtanga primary series.
