BeginnerseatedHead-to-Knee Forward Bend
Janu Sirsasana · जानुशीर्षासन
Also known as: Janu Sirsasana · Head-to-Knee Pose
Head-to-Knee Forward Bend, also called Janu Sirsasana is a classical yoga posture. Its Sanskrit name Janu Sirsasana translates word-for-word as: Janu (Knee) · Sirsa (Head) · Asana (Pose). In this posture, the body grounds through the sit bones while the spine rises tall. The posture works to lengthen the hamstrings, release the lower back and stretch the hip flexors. Stimulates the liver and kidneys. Calms the brain and relieves mild depression. Suitable for beginners and regular practitioners alike, it is a calming cool-down, particularly beneficial for beginners and seniors. A blanket and strap can be used to make the posture more accessible and support correct alignment. Practitioners with digestive problems and knee injury should approach with care or consult a qualified teacher.
Anatomy Involved
Benefits
Hamstrings(lengthening)
The prominent muscles running along the back of your straight leg's thigh (hamstrings) receive a deep, sustained stretch in Janu Sirsasana. As you hinge from the hips and extend forward, these muscles are asked to lengthen, releasing the chronic tension often held from prolonged sitting or athletic activity. In an Iyengar approach, we seek a balanced, intelligent stretch that allows the nervous system to gradually soften their grip, enhancing flexibility and reducing strain on the pelvis and lower back. This release allows for a freer flow of apana vayu, bringing a sense of groundedness and ease to the entire posterior chain.
Erector Spinae(lengthening)
The long, deep muscles running along either side of your spinal column (erector spinae) are actively lengthened as you fold forward from the hips, rather than rounding the back. This action encourages space between the vertebrae, decompressing the spinal discs and improving the mobility of the spine itself. By consciously extending the spine from the tailbone through the crown of the head, we prevent collapse and instead cultivate a feeling of spaciousness and lightness in the torso. This gentle elongation helps to release stored tension in the back body, fostering a sense of freedom and energetic uplift along the central channel.
Gluteal Muscles(releasing)
The large muscles of the buttocks (gluteal muscles), particularly the gluteus maximus, are gently released and stretched as the pelvis tilts forward over the straight leg. This allows for a deeper hinge at the hip joint and facilitates the forward bend. Releasing these powerful muscles helps to alleviate tightness that can pull on the sacrum and lower back, improving overall hip mobility and comfort. Energetically, this release helps to unbind stagnation in the pelvic floor, allowing for a more open and grounded experience in the lower body.

Avoid If
Asthma
Vigorous effort and deep chest compression can trigger bronchospasm in those with reactive airways.
Avoid deep forward folds that compress the chest; keep the torso at 45 degrees with hands on blocks.
Diarrhea
Twisting and strong abdominal compression stimulate intestinal peristalsis, which can worsen diarrhoea.
Rest and allow the digestive system to recover; practise only very gentle, restorative postures.
Knee Injury
Deep flexion or rotation at the knee can strain ligaments, meniscus, or cartilage, especially in a compromised joint.
Bend the knees generously to protect the joint and keep the weight in the heels rather than the toes.
Back Injury / Back Pain
Spinal flexion, extension, or rotation under load can compress vertebral discs or strain the paraspinal muscles.
Bend both knees generously, hinge from the hips rather than rounding the spine, and rest hands on blocks or thighs.
Props That Can Help
Optional supports — use when helpful, not required
Folded Blanket
Place a folded blanket under the sitting bones to ease the forward tilt of the pelvis and reduce strain at the hamstring attachment.
Yoga Strap
Loop a strap around the feet when the hands cannot reach — this maintains proper spinal length and prevents rounding the lower back to close the gap.
See variation →Bolster
Rest the torso on a bolster in the fold for a completely supported, restorative version that releases the back body without effort.
