Half Lord of the Fishes Pose
Ardha Matsyendrasana · अर्ध मत्स्येन्द्रासन
Also known as: Half Spinal Twist · Seated Spinal Twist · Half Fish Pose
Half Lord of the Fishes Pose, also called Half Spinal Twist is a classical yoga posture. Its Sanskrit name Ardha Matsyendrasana translates word-for-word as: Ardha (Half) · Matsyendra (Lord of Fish (Sage)) · Asana (Pose). In this posture, the body rotates the spine, creating space between each vertebra. The posture works to engage the obliques. Stimulates the abdominal organs. Relieves back pain. Suitable for intermediate practitioners with foundational yoga experience, it is a meaningful addition to any practice, particularly beneficial for seniors and beginners. A blanket and block can be used to make the posture more accessible and support correct alignment. Practitioners with pregnancy and hip injury should approach with care or consult a qualified teacher.

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.
Hip Injury
Deep hip flexion, external rotation, or weight-bearing can aggravate labral tears, impingement, or bursitis.
Limit the range of hip movement, avoid positions that cause clicking or sharp pain, and use props to support the hip.
Pregnancy
Deep twists, abdominal compression, and lying flat on the back can restrict blood flow or cause discomfort as pregnancy progresses.
Twist from the upper thoracic spine only, opening the chest rather than compressing the abdomen; use a chair for support.
Headache / Migraine
Physical exertion, inversions, and strong breath work can intensify an existing headache or trigger a migraine.
Avoid inversions and strong pranayama; rest in a supported, restorative posture with a cool cloth on the forehead.
Props That Can Help
Optional supports — use when helpful, not required
Folded Blanket
Use a blanket for cushioning, elevation, or support — it adapts the pose to your body's current needs without compromising alignment.
Yoga Block
Use a block to reduce the reach distance, support alignment, and make the posture accessible at your current level of flexibility.
