Parivrtta Janu Sirsasana (Chair) · परिवृत्त जानु शीर्षासन (कुर्सी)
Also known as: Chair Janu Sirsasana Twist
Revolved Head-to-Knee Pose in Chair, also called Chair Janu Sirsasana Twist is a classical yoga posture. Its Sanskrit name Parivrtta Janu Sirsasana (Chair) translates word-for-word as: Parivrtta (Revolved) · Janu (Knee) · Sirsa (Head) · Asana (Pose in Chair). Seated on the mat, the practitioner rotates the spine, creating space between each vertebra. The posture works to lengthen the hamstrings, strengthen and extend the back and release tension in the hips. Stretches the hamstrings. Gently rotates the spine. It is particularly valued for developing greater flexibility and alleviating back discomfort. Suitable for beginners and regular practitioners alike, it is a calming cool-down, particularly beneficial for seniors and beginners. A chair can be used to make the posture more accessible and support correct alignment. Practitioners with spinal injury and abdominal surgery should approach with care or consult a qualified teacher.
Anatomy Involved
Benefits
Hamstrings(lengthening)
The prominent muscles at the back of your extended thigh (hamstrings) receive a sustained, intelligent lengthening here, rather than an aggressive pull. By maintaining a stable pelvic base on the chair and reaching with awareness, you encourage these muscles to gradually release chronic tension, which often restricts hip flexion and can contribute to lower back discomfort. Yogically, this release in the posterior chain helps to ground apana vayu, bringing a sense of stability and ease to the pelvic floor and lower extremities, improving overall leg flexibility.
Obliques(lengthening | activating)
The diagonal muscles along your side waist (obliques) on the side bending over are extensively lengthened, while those on the opposite side are gently engaged to support the twist and lateral flexion. This dual action helps to decompress the abdominal cavity and improve the elasticity of the trunk muscles, enhancing their ability to stabilize the spine. From a yogic perspective, this creates space in the side body, allowing for a freer flow of prana through the manipura chakra region, fostering vitality and digestive health.
Quadratus Lumborum(lengthening)
This deep muscle in your lower back, connecting your ribs to your pelvis (quadratus lumborum), experiences a significant lengthening on the side of the lateral bend. Chronic tightness in this area is a common source of lower back pain and stiffness, restricting spinal movement. By gently stretching this muscle, we create more space in the lumbar region, alleviating compression and improving the kidney's energetic function. This release helps to unwind deep-seated tension, allowing for greater comfort and mobility in daily movements and deeper breathing.

Avoid If
Back Injury / Back Pain
Spinal flexion, extension, or rotation under load can compress vertebral discs or strain the paraspinal muscles.
Initiate the twist from the upper spine and ribs rather than forcing from the waist; keep both sitting bones grounded.
Hamstring Injury
Aggressive stretching of a torn or strained hamstring can reinjure muscle fibres — the attachment near the sitting bone is especially vulnerable.
Bend the knees generously, work within a pain-free range, and avoid any aggressive pulling on the hamstrings.
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.
Props That Can Help
Optional supports — use when helpful, not required
Chair
Sit sideways on a chair and use the back rest for leverage — this is the most accessible form of a spinal twist for any body.
