Matsyasana (Fish Pose) is a gentle, reclining backbend and chest-opener from hatha yoga. Traditionally it’s taught as a counter-pose to Shoulderstand (Sarvangasana) and, in classical variations, with the legs in Padmasana (Lotus). Modern practice commonly uses straight or bent legs and props for accessibility. The name comes from Sanskrit: matsya = fish, asana = posture.
How to Do Matsyasana/fish pose (Step by Step)
- Set up
Lie on your back. Bend the knees, feet on the mat. Slide both hands (palms down) under your buttocks and keep your forearms close to your sides. - Lift and open
Press forearms and elbows into the floor, draw shoulder blades toward one another, and lift your chest/thoracic spine. - Place the head lightly
Gently allow the head to tip back so either the back of the head or the crown just touches the floor—with minimal weight to avoid neck compression. - Leg options
Keep knees bent or extend the legs long, activating the thighs and pressing through the heels. (Traditionally, Lotus legs are used, but not required.) - Breathe and hold
Stay 15–30 seconds (or several slow breaths), keeping the throat soft and the breath easy. - Exit safely
On an exhale, press the forearms down, lift the head slightly to neutral, lower the upper back, then release and hug the knees to the chest.
Tip: If you feel any neck or throat discomfort, lower the chest and/or place a folded blanket under the back of the head.
Benefits (What Practitioners Commonly Experience)
- Opens the chest and rib cage (intercostals) and stretches the front body (abdominals, hip flexors).
- Strengthens the upper back and posterior neck while encouraging better posture.
- Breath capacity awareness: the chest-lifting shape often makes deeper breathing feel more accessible; many practitioners report an energizing or mood-lifting effect.
Anatomy Spotlight (What’s Happening in the Body)
- Spinal extensors (erector spinae) create thoracic extension to lift the sternum.
- Scapular retractors/depressors (rhomboids, middle–lower trapezius) draw shoulder blades together and down to broaden the chest.
- Hip flexors—especially psoas major—can play a role in spinal extension mechanics and leg variations; the pose is an excellent demo of psoas’ dual roles (hip flexion and spinal action).
- Lengthening tissues: pectoralis major/minor, intercostals, and the anterior neck (including sternocleidomastoid and platysma) receive a sustained stretch when the chest lifts and the head gently extends.
Neck safety: Keeping the work in the thoracic spine and shoulder blades (not jamming into the cervical spine) protects the neck. If your elbows support more of the lift, there’s usually more ease in breathing and less neck load.
Preparatory Poses
These help mobilize the thoracic spine and open the front body before Fish Pose:
- Bhujangasana (Cobra), Urdhva Mukha Svanasana (Upward-Facing Dog) – front-body opening
- Salabhasana (Locust), Dhanurasana (Bow) – back-body engagement
- Setu Bandha Sarvangasana (Bridge) – supported backbend pattern
- Baddha Konasana, Virasana/Supta Virasana – hip and quad prep
- Gentle chest openers on props (rolled blanket or blocks) to pattern thoracic extension
Contraindications & When to Modify
- Neck, shoulder, or back injury/pain: Avoid or use a supported version (bolster or rolled blanket under the upper back; head on a block/blanket).
- Uncontrolled high/low blood pressure, migraines/headaches: Practice only with medical guidance and prefer supported variations; exit if symptoms arise.
- Pregnancy (especially 2nd/3rd trimester): Long, flat supine positions may compress the vena cava; choose side-lying or propped-up alternatives instead of flat Matsyasana.
- Glaucoma / eye-pressure concerns: Evidence most strongly advises avoiding head-down/inverted poses; Fish isn’t head-down, but if you’ve been told to avoid positions that raise eye pressure, keep the head elevated on a block or choose another chest-opener. Consult your ophthalmologist.
Variations & Props (to fit different bodies)
- Supported Fish (Restorative): Lie back over a bolster or a rolled blanket across the shoulder blades; another block/blanket can support the head. Great for beginners or anyone with neck sensitivity.
- Block setup: One block lengthwise under the thoracic spine and one under the head; arms relaxed.
- Classical legs: Padmasana (Lotus) if it’s already in your practice (not required).
Alignment Keys (Quick Cues for Safe Practice)
- Root the forearms and elbows; let them, not the head, bear weight.
- Lift the sternum up and back; think “open the front ribs” rather than “throw the head back.”
- Keep the throat soft and breath smooth; exit if the neck feels compressed.
Putting It in a Sequence
Before: one or two of the preparatory poses above.
After: gentle neutralization (hug knees to chest), then a mild backbend or neutralizer like Bridge or Virasana to balance.
