Head To Knee Janu Sirsasana Yoga Pose
Head To Knee Janu Sirsasana Yoga Pose Exercise Description
Head to Knee (Janu Sirsasana) is a seated, single‑leg forward‑fold stretch that targets the hamstrings of the extended leg while also lengthening the calves and the muscles along the back (spinal extensors). One knee bends outward with the sole of that foot placed to the inner thigh, encouraging gentle adductor opening on the bent‑leg side. The movement emphasizes a controlled hip hinge first—creating length through the spine—followed by a comfortable forward fold toward the extended leg. Proper alignment keeps the pelvis squared to the straight leg, the knee and toes of the extended leg pointing up, and the ankle dorsiflexed for a more complete posterior‑chain stretch. Props such as a folded blanket (under the sitting bones) or a strap (around the foot) help maintain a neutral spine and clean hinge mechanics without forcing range.

How To Do The Head To Knee Janu Sirsasana Yoga Pose Exercise
‘- Sit tall with both legs extended; place a folded blanket under your sitting bones if the pelvis tucks under.
– Bend one knee and place the sole of that foot against the inner thigh of the opposite leg (above the knee joint, not on it).
– Square your chest and pelvis toward the straight leg; align the extended knee and toes to the ceiling.
– Dorsiflex the extended ankle (toes back toward you) and gently “root” both sitting bones.
– Inhale to lengthen the spine; exhale to hinge forward from the hips, keeping the back long.
– Reach hands to shin, ankle, foot, or a strap around the ball of the foot—avoid shrugging the shoulders.
– Keep a soft micro‑bend in the extended knee if you tend to lock out; maintain even contact through the heel.
– Allow a gradual, comfortable fold; the head does not need to touch the knee. Keep the neck long.
– Breathe steadily, sensing stretch in the back of the extended thigh without sharp pain or pinching.
– To exit, lead with the chest to come upright, straighten the bent leg, and repeat on the other side.
Head To Knee Janu Sirsasana Yoga Pose Tips
‘- Sit on a folded blanket if your pelvis tucks under so you can sit tall before folding.
– Place the sole of the bent leg’s foot against the inner thigh of the straight leg, above the knee joint, not directly on it.
– Square your chest and pelvis straight toward the extended leg before you hinge forward.
– Keep the extended leg’s knee and toes pointing up toward the ceiling throughout the pose.
– Dorsiflex the extended ankle by drawing the toes back toward you while gently rooting both sitting bones.
– Inhale to lengthen your spine first, then exhale to hinge from the hips so the back stays long rather than rounding.
– Reach only as far as shin, ankle, foot, or a strap without letting the shoulders shrug up toward the ears.
– Use a soft micro‑bend in the extended knee if you tend to lock it out.
– Let the fold be gradual and comfortable; the head does not need to touch the knee, and the neck stays long.
– Breathe steadily, feeling a stretch in the back of the extended thigh but not sharp pain or pinching.
Head To Knee Janu Sirsasana Yoga Pose Beginner Introduction
Head to Knee (Janu Sirsasana) is a yoga forward bend done from the floor with one leg long and the other leg bent to the side. The posture centers on length along the back of the straight leg, giving a deep stretch through the back of the thigh and into the calf, while also creating a gentle opening through the inner thigh of the bent leg. Because the spine extends forward from the hips rather than rounding abruptly, the muscles along the back of the torso are invited into a long, even curve instead of a collapse.
Alignment plays a big role in this shape. The front of the body faces the extended leg, with the straight leg’s knee and toes pointing upward and the ankle actively flexed to involve more of the back line of the leg. A folded blanket under the sitting bones or a strap around the foot often supports a tall, organized spine and a smooth hinge at the hips, encouraging a steady, comfortable stretch rather than forcing depth.
