Head-to-Knee Pose is a one-legged seated forward bend that combines a hamstring stretch on the straight leg with a gentler opening through the inner thigh and hip of the bent leg. The shape works best when you think of length first and depth second.
Although the name suggests bringing the head all the way down, that is not the main point. What matters more is organising the pelvis and spine so the fold comes from a steady hinge rather than a collapse. Many people will feel this clearly in the back of the straight leg. Others may need to bend that knee or sit on support to keep the lower back from rounding too much. Comfortable range differs from body to body.
How to do Head-to-Knee Pose
Sit with both legs extended in Staff Pose.
Bend your right knee and bring the sole of the right foot to the inner left thigh or calf, keeping the right knee comfortable rather than forcing it down.
Place your hands beside your hips and lift through the spine. If you are tipping back onto the tailbone, sit on a folded blanket.
Turn your chest broadly toward the straight left leg so your navel, breastbone and nose are more or less facing that leg.
Inhale and reach both arms up or simply lengthen the spine forward from the hips.
Exhale and fold toward the left leg, letting your hands rest on the shin, ankle, foot or the floor wherever you can keep the chest from collapsing heavily.
Keep the straight leg active with the toes pointing upward, and let the bent leg soften without pressing the knee down.
Stay for 5 to 10 slow breaths. On each inhale, find a little more length through the front of the body. On each exhale, soften only if the spine can stay reasonably long.
To come out, inhale and rise back up slowly, extend the bent leg forward, and repeat on the second side.
Yogita's tip
If the bent-knee side keeps lifting and pulling you off centre, place a folded blanket under that outer thigh or knee. That small support often helps the pelvis settle so the forward fold feels clearer in the straight leg instead of strained in the groin.
Benefits
Lengthens the back of the straight leg in a more manageable way than a two-legged forward fold for many people.
Gives a gentle opening through the inner thigh and hip of the bent leg.
Practises hinging forward from the pelvis while keeping the spine organised.
Can help you notice left-right differences in hamstrings, hips and sitting posture.
Offers a steady, quieter shape for breath awareness near the end of practice.
Common mistakes
Forcing the head toward the knee and losing length through the front of the body.
Letting the straight-leg foot roll out so the leg becomes passive.
Pulling hard on the foot or strap instead of folding gradually with the breath.
Pressing the bent knee down even when the inner knee or groin feels strained.
Rounding the lower back deeply because the hips are not quite ready for the depth.
Make it work for you
Sit on a folded blanket
Lift your hips on one or more folded blankets if your pelvis tips backward. This usually makes it easier to lengthen the spine before folding.
Bend the straight knee slightly
Keep a small bend in the straight leg if the hamstrings pull strongly or the lower back rounds. You can place a rolled blanket under the knee for support.
Use a strap around the foot
Loop a strap around the straight foot and hold the strap with both hands so you can keep the chest broad without straining the shoulders or back.
Support the bent knee
Place a block, folded blanket or cushion under the bent knee or outer thigh if that side feels unsupported.
Alternatives
Seated Forward Fold
Practise with both legs extended and keep the knees bent as much as needed to find a more even, centred fold.
Use this if the asymmetry of one bent leg feels awkward or irritating to the knee.
Bound Angle Pose
Sit upright with the soles of the feet together and stay lifted rather than folding deeply.
Choose this if straightening one leg strongly pulls at the hamstrings.
Reclining Hand-to-Big-Toe Pose
Lie on your back and stretch one leg upward with a strap while the other leg rests on the floor.
This is useful if sitting upright on the floor is difficult or if you want to reduce the load on the back.
Common variations
Upright Head-to-Knee Pose
Stay upright with the hands on the floor or on blocks beside the straight leg, focusing on spinal length instead of the forward fold.
Side-Reaching Variation
Turn slightly toward the straight leg and reach the same-side hand to the foot while the other arm arcs overhead for a mild side bend.
Supported Forward Fold
Rest the forearms, forehead or chest on bolsters or folded blankets over the straight leg for a quieter, more supported version.
Safety and contraindications
When to avoid or get individual guidance
Recent hamstring strain
Painful inner knee irritation on the bent-leg side
Acute lower back pain aggravated by forward bending
Keep the bent knee comfortable. If you feel strain along the inner knee, move the foot farther away from the groin or support the thigh.
Bend the straight knee slightly if the stretch feels pinchy behind the knee or if your lower back rounds sharply.
Use support under the hips if sitting upright is difficult; this often makes the pose safer and clearer.
Pause Janu Sirsasana and back off if you get sharp knee pain, a strong pull high near the sitting bone, or back discomfort that does not settle soon after coming up. Get individual guidance before continuing.
Accessibility and limited mobility
If getting down to the floor is difficult, choose a higher seat on firm folded blankets so the pelvis can tilt forward more easily.
Older adults or anyone with limited hamstring range often do better with the straight knee bent and the hands resting on blocks.
If the bent knee does not comfortably lower outward, support it rather than trying to make it match the other side.
Easier options
Use these related poses when you want a more accessible way to practise a similar movement or prepare for this pose.
No. The name can be misleading. For most people, the more useful aim is to lengthen forward from the pelvis and keep the breath steady. Your head may stay well above the knee and the pose can still be well done.
Why does the bent knee feel awkward in this pose?
That usually means the hip is not comfortably opening enough for the knee to rest there on its own. Move the foot a little farther away from the groin and place support under the bent thigh or knee. The shape should feel supported, not forced.
Should the straight leg stay completely straight?
Not necessarily. A small bend is often the better choice if the stretch catches behind the knee or pulls your lower back into a heavy round. Keeping the spine clearer matters more than making the leg perfectly straight.
Where should I hold if I cannot reach my foot?
Hold your shin, ankle, a strap around the foot, or even place your hands on the floor beside the leg. Choose the place that lets your shoulders stay soft and your chest gently broad.
Is it better to stay upright or fold deeper?
If staying upright gives you a clearer sense of lifting through the spine and hinging from the hips, that is often the better version for now. Depth is useful only if it does not turn into strain or collapse.
