Full Lord of the Fishes Pose anatomy

Full Lord of the Fishes Pose · Paripurna Matsyendrasana · Tư thế vặn cột sống ngồi toàn phần

Full Lord of the Fishes Pose mainly works external oblique (right), internal oblique (left), multifidus (right), erector spinae; it stretches gluteus medius, gluteus minimus (right), quadriceps (right), tibialis anterior (right); transversus abdominis stabilize.

Opening the 3D model…

Sit tall and place the top of the right foot in the left hip crease as in Half Lotus, the right knee lowering toward the floor. Bend the left knee up and set the left foot on the floor outside the right knee. Inhale to lengthen the spine; exhale and turn the torso to the left, bringing the right armpit outside the left knee. The right arm wraps around the outside of the left knee to hold the left foot; the left arm reaches back and around the left hip to hold the right foot in the hip crease. Gaze over the left shoulder. This is the full form of Half Lord of the Fishes: the right hip turns out deeply and the right knee bends fully, the left buttock and outer hip stretch, and the obliques and deep back muscles rotate the spine; the left shoulder rotates inward and extends back, so its front stretches. It is very demanding: build a steady Half Lotus and seated twist first, and come out at once with knee pain.

Muscles in this pose

Working (contracting): External oblique (right), Internal oblique (left), Multifidus (right), Erector spinae, Subscapularis, Rhomboid major (left), Sternocleidomastoid (right)

Stretching: Gluteus medius, Gluteus minimus (right), Quadriceps (right), Tibialis anterior (right), Fibularis group (right), Adductors (right), Gluteus maximus (left), Tensor fasciae latae (left), External oblique (left), Internal oblique (right), Infraspinatus, Teres minor, Pectoralis major (left), Deltoid (left), Biceps brachii (left)

Stabilizing: Transversus abdominis

Why these muscles work or stretch

• External oblique · Working (contracting): The opposite-side external oblique and same-side internal oblique turn the chest toward the twist
• Multifidus · Working (contracting): Multifidus rotates the vertebrae toward the opposite side
• Erector spinae · Working (contracting): Keeps the spine long, without rounding in the twist
• Subscapularis · Working (contracting): Turns the shoulder inward so the arm can wrap back and clasp the other hand
• Rhomboid major · Working (contracting): Draws the shoulder blade toward the spine to open the chest
• Sternocleidomastoid · Working (contracting): Turns the head to look over the left shoulder
• Gluteus medius · Stretching: Right: front fibers stretch in deep external rotation; left: the hip crosses the midline
• Quadriceps · Stretching: Right knee fully bent
• Tibialis anterior · Stretching: Right foot pointed, resting in the left hip crease
• Fibularis group · Stretching: Ankle in inversion, sole turned up
• Adductors · Stretching: The half-lotus knee opens out to the side
• Gluteus maximus · Stretching: The raised knee draws toward the opposite side of the chest
• Tensor fasciae latae · Stretching: The left hip adducts across the midline
• Infraspinatus · Stretching: The shoulder external rotators lengthen as the shoulder turns inward
• Pectoralis major · Stretching: The chest on the side of the arm behind the back stretches as the shoulder extends
• Deltoid · Stretching: The front fibers stretch as the shoulder extends back
• Biceps brachii · Stretching: The long head stretches as the shoulder extends back

Practice cues

• Bring the right foot to the hip crease by turning out from the hip joint, never by twisting the knee
• Lengthen the spine first, then twist as you exhale, from the belly up to the chest
• Ground both sitting bones evenly; turn the head last and keep the neck soft

Benefits

• Improves spinal rotation
• Deeply stretches the outer hip and ankle of the half-lotus leg and the buttock of the raised knee
• Stretches the front of the shoulder and the shoulder external rotators

Cautions / contraindications

• Avoid with a knee, meniscus, knee ligament or ankle injury; never force the foot into the hip crease
• Avoid with a shoulder or rotator cuff injury
• Avoid during pregnancy, with a herniated disc or acute low back pain

Easier variations

• Fold the right leg on the floor with the heel by the left hip, as in Half Lord of the Fishes, instead of Half Lotus
• Loop a strap around the left foot and hold it with the right hand; the left hand presses the floor behind
