Half Moon Pose
Ardha Chandrasana · अर्ध चंद्रासन
Also known as: Half Moon · Ardha Chandrasana
Half Moon Pose, also called Half Moon is a classical yoga posture. Its Sanskrit name Ardha Chandrasana translates word-for-word as: Ardha (Half) · Chandra (Moon) · Asana (Pose). From a standing position, the body roots firmly through the feet while the spine extends upward. The posture works to lengthen the hamstrings, strengthen the quadriceps and activate the glutes. Improves balance and coordination. Stretches hamstrings, calves, and spine. It is particularly valued for building full-body strength and developing greater flexibility. Suitable for intermediate practitioners with foundational yoga experience, it is a meaningful addition to any practice, particularly beneficial for teens and athletes. A block and wall can be used to make the posture more accessible and support correct alignment. Practitioners with migraine and low blood pressure should approach with care or consult a qualified teacher.
Anatomy Involved
Benefits
Hamstrings(lengthening)
The muscles along the back of the standing thigh (hamstrings) experience a deep, intelligent lengthening as the torso extends forward and the leg lifts. This eccentric loading helps to increase flexibility in the posterior chain, releasing chronic tightness often held from prolonged sitting. In a yogic sense, this unwinds old patterns of resistance, allowing for a greater flow of apana vayu and a sense of freedom through the back of the leg and pelvis.
Quadriceps(strengthening)
The powerful muscles on the front of the standing thigh (quadriceps) engage intensely to stabilize the knee and support the body's weight, particularly the vastus medialis which helps prevent knee collapse. This isometric contraction builds significant strength and endurance in the leg, creating a solid foundation for the pose. This engagement cultivates tapas, inner heat, which purifies and strengthens the physical structure, allowing the practitioner to feel more grounded and powerful.
Glutes(strengthening)
The muscles of the buttocks and outer hip (gluteus maximus and medius) are crucial in Ardha Chandrasana, working both to extend the lifted leg and to stabilize the standing hip. The gluteus medius, in particular, prevents the standing hip from collapsing inwards, maintaining pelvic alignment. This deep activation brings strength and stability to the pelvis, which is the seat of creativity and security, fostering a sense of rootedness and balance in the practitioner's energetic body.

Avoid If
Headache / Migraine
Physical exertion, inversions, and strong breath work can intensify an existing headache or trigger a migraine.
Keep effort minimal, breathe slowly, and skip any vigorous transitions.
Low Blood Pressure
Rising quickly from low positions can cause a sudden drop in blood pressure, leading to dizziness or fainting.
Rise slowly from seated or lying positions, pause in a mid-level shape before fully standing, and use a wall for support.
Insomnia
Stimulating pranayama and energising poses can activate the sympathetic nervous system, making sleep harder if practised late in the day.
Practise calming, exhalation-focused breath work; avoid stimulating postures or pranayama close to bedtime.
Ankle Injury
Unstable or injured ankle joints can be overstressed by weight-bearing, extreme dorsiflexion, or plantar flexion.
Place a folded blanket under the ankle to cushion it, or practise a seated version of the pose.
Props That Can Help
Optional supports — use when helpful, not required
Yoga Block
Use a block to reduce the reach distance, support alignment, and make the posture accessible at your current level of flexibility.
See variation →Wall
Practise near the wall so one fingertip can lightly touch it, giving the nervous system a safety anchor while building proprioceptive confidence.
