DAILY YOGA ยท Parivrtta Janu Sirsasana
Revolved Head-to-Knee
Parivrtta Janu Sirsasana โ Revolved Head-to-Knee Pose โ is a seated side-bend over one straight leg with a twist, opening the entire side body while stretching the hamstring. It is a beautiful, lengthening pose that combines a lateral bend, a gentle twist and a hamstring stretch.
Name meaning: From parivritta meaning "revolved", jฤnu meaning "knee", ลฤซrแนฃa meaning "head", and ฤsana โ the "revolved head-to-knee posture", a twisting, side-bending fold over one straight leg.
Classification: Asana โ a seated side-bend, twist and forward fold combined.
Tradition & origin: Revolved Head-to-Knee is modern: like Janu Sirsasana (first seen in Krishnamacharya's 1934 Yoga Makaranda) it is a 20th-century pose, not found in the medieval hatha texts. Present it as modern postural yoga.

How to do it โ step by step
- 1Sit with the right leg extended and the left foot to the inner right thigh (like Janu Sirsasana).
- 2Turn the torso to open toward the left (away from the straight leg).
- 3Lower the right side toward the right leg, resting the right forearm/hand along the shin.
- 4Sweep the left arm overhead, reaching toward the right foot.
- 5Turn the chest open toward the ceiling as you side-bend.
- 6Lengthen the top side body; gaze up if the neck allows.
- 7Rise and switch sides.
Breath & hold
Breathe into the top-side ribs; hold 30โ45 seconds each side.
Benefits
- โStretches the hamstring and the entire side body.
- โOpens the chest, shoulders and ribs.
- โAdds a gentle twist to lengthen the spine.
- โCalming and spacious.
๐ช The traditional / desi way
- The "revolved" head-to-knee โ the classic forward bend opened out into a long, luminous side-bend.
- Traditional cue: reach out of the top arm and keep the chest turning up; length along the top side, not a collapse down.
Common mistakes
- โCollapsing the chest toward the floor instead of opening it up.
- โStraining to reach the foot and rounding.
- โCrunching the neck.
Modifications & props
- ๐งฉHold the shin or use a strap around the extended foot.
- ๐งฉSit on a folded blanket to tilt the pelvis forward.
Muscles & anatomy
- ๐ชStretches the whole top side body (waist, ribs, obliques) and the hamstring of the straight leg.
- ๐ชOpens the chest as it turns toward the ceiling.
- ๐ชThe bent-leg hip opens as you settle.
What you may feel
- ๐ซงNormal: a long stretch along the top side body and a hamstring stretch, with the chest opening up.
- ๐ซงWarning sign: low-back or hamstring strain โ sit on a cushion, bend the knee, and lengthen rather than reaching far.
Variations to grow into
Rest the top hand on the shin or a strap and revolve the chest a little more toward the ceiling.
Reach the top hand to the extended foot and the bottom hand to the inner foot, deepening the twist and side stretch.
Using props
- ๐งฑA strap around the extended foot.
- ๐งฑA folded blanket under the hips to tilt the pelvis forward.
Warm-up & counterpose
- Seated side bends and gentle forward folds to warm the side body and hamstrings.
- A neutral forward fold or gentle twist to release.
Supporting exercises
Why: Builds the hamstring and hip openness without the side-bend.
How: Fold forward over one straight leg.
Why: Frees the waist and ribs for the side stretch.
How: Reach one arm overhead and lean gently to the side.
Progression path
Start with the top hand on the shin and a strap on the foot; deepen the side-bend and twist as the waist and hamstrings open, keeping the spine long.
Who it suits โ and who should modify
- โMost practitioners with reasonable hip and side-body mobility.
- โThose wanting a deep side-body stretch with a gentle twist and hamstring stretch.
- โAnyone easing tightness along the waist and ribs.
- !Lower-back or disc injury โ keep the side-bend gentle and sit on a cushion.
- !Hamstring injury โ bend the extended knee slightly or use a strap.
- !Shoulder issues โ keep the top arm lower; do not force the reach.
When to practise
In the seated part of a practice, once the hips and side body are warm.
A few times a week; hold 30โ45 seconds each side.

Myths vs. reality
โ Myth: You must reach your foot and lay the head on the knee.
โ Reality: The side-body stretch and gentle twist are the point; reaching far with a rounded spine misses it. Use a strap.

โ Reality: It is a modern pose (20th century), like Janu Sirsasana.
โ ๏ธ Cautions
- Lower-back or hamstring issues โ sit on a cushion, bend the straight-leg knee slightly, and keep the reach modest.
