Ūrdhva Dhanurāsana (Full Wheel / Upward Bow Pose) is the culminating backbend of the Primary Series, performed three times for five breaths each after the final seated vinyāsa. It represents the peak of spinal extension in the Yoga Chikitsā sequence, demanding integrated strength and openness across the entire anterior chain. As a deep backbend it serves as the energetic counterbalance to the many forward folds that dominate the seated series.

From Sanskrit ūrdhva (upward), dhanu (bow), and āsana (seat/pose). The body forms the shape of an archer's bow turned upward, with the hands and feet as the two ends and the spine as the curved shaft. It is sometimes called Chakrāsana (wheel pose) in other traditions, though in Ashtanga that term refers to the backward roll used as a transitional movement.

Ūrdhva Dhanurāsana does not follow a traditional numbered vinyāsa count. From a supine position, the practitioner places the hands beside the ears and feet hip-width apart, then presses up on an inhale. Three repetitions are taken, each held for five breaths. Between repetitions the practitioner lowers down on an exhale and resets before pressing up again on the next inhale.

After completing the final seated pose and its closing vinyāsa, the practitioner lies down supine. The hands are placed beside the ears with fingers pointing toward the shoulders, elbows parallel and pointing toward the ceiling. The feet are set flat on the floor hip-width apart, heels drawn close to the sitting bones. On an inhale, the practitioner presses firmly through hands and feet to lift the entire torso off the floor into the full arch.

In the full expression, the arms and legs are as straight as possible, the chest opens toward the wall behind, and the hips lift high. The weight distributes evenly between hands and feet while the inner thighs rotate slightly inward to protect the lumbar spine. The breath remains steady and full despite the deep opening of the thoracic cavity. After five breaths, the practitioner tucks the chin slightly and lowers down vertebra by vertebra on an exhale, then repeats for a total of three rounds.

After the third repetition, the practitioner lowers down and may hug the knees to the chest briefly. In the traditional method, advanced practitioners may drop back from standing and come back up (called 'drop-backs'), guided by the teacher. The practitioner then prepares for Paścimatānāsana as a counter-stretch before transitioning into the shoulderstand sequence.

Nāsāgra dṛṣṭi (tip of the nose) is the prescribed gaze point in Ūrdhva Dhanurāsana. In practice, some teachers allow the gaze to settle naturally between the hands on the floor behind, as the neck is in full extension. The key is that the eyes remain soft and steady rather than darting, maintaining internal focus even in this demanding posture.

Mūla bandha is essential to protect the lumbar spine and channel energy upward through the central axis. Uḍḍīyāna bandha engages lightly to support the lower back and prevent excessive compression of the lumbar vertebrae. The bandhas help distribute the backbend more evenly across the thoracic spine rather than hinging at L4-L5, which is a common source of pain in this pose.

The feet remain parallel and hip-width apart, resisting the tendency to splay outward. The knees track over the ankles rather than splaying wide, maintained by engaging the inner thighs with slight internal rotation. The hands press down evenly through the index finger mound to prevent wrist compression, and the arms work toward full extension. The chest drives toward the wall behind to emphasize thoracic extension, and the head hangs naturally without crunching the cervical spine.

The most frequent error is collapsing the knees outward, which compresses the sacroiliac joints and lumbar spine. Allowing the feet to turn out creates external rotation that dumps pressure into the lower back. Many practitioners push primarily from the arms, neglecting the leg drive that should lift the hips high. Another common mistake is holding the breath or clenching the jaw, both of which prevent the full opening that steady ujjāyī breathing supports.

Ūrdhva Dhanurāsana is a full-body pose demanding significant extension of the spine, particularly the thoracic vertebrae. The hip flexors (iliopsoas, rectus femoris) and the entire anterior chain including rectus abdominis and pectoralis major are deeply stretched. The gluteus maximus, hamstrings, deltoids, and triceps work concentrically to maintain the arch. The wrists are in full dorsiflexion under load, requiring adequate mobility and strength in the forearm extensors.

This pose is considered invigorating and is used therapeutically to counteract the effects of prolonged sitting and forward-hunched posture. It opens the chest and can improve respiratory capacity by stretching the intercostal muscles and diaphragm. The pose stimulates the adrenal glands and is traditionally said to boost energy and combat fatigue. It can be beneficial for mild depression when practiced consistently, as backbends are considered heart-opening and uplifting in the yogic tradition.

Beginners or those with limited thoracic mobility may practice Setu Bandhāsana (Bridge Pose) as a preparatory alternative, lifting the hips while keeping the shoulders on the floor. Pressing up to the crown of the head as an intermediate stage allows the practitioner to build strength and open the shoulders before full extension. Blocks placed against a wall under the hands can reduce the range of motion required at the wrists and shoulders. A teacher may also assist by supporting the mid-back to help the student find the thoracic opening.

The entire Primary Series of forward folds and hip openers prepares the body progressively for Ūrdhva Dhanurāsana. Sūrya Namaskāra A and B warm up the spine with Ūrdhva Mukha Śvānāsana (Upward Dog) in each vinyāsa. Setu Bandhāsana (Bridge Pose) is a direct preparation that activates the same muscle groups with less demand. Pūrvottānāsana in the seated series serves as an earlier counter-pose and backbend preparation.

Paścimatānāsana (Intense West Stretch) is taken immediately after the three wheels as a direct counter-stretch, held for ten breaths to release the spine. This is one of the rare moments in the Primary Series where a specific counter-pose is deliberately inserted. The subsequent shoulderstand sequence (Sarvāṅgāsana) also serves as a powerful counterbalance by reversing the spinal direction completely.

Ūrdhva Dhanurāsana represents the courage required to open the heart center (anāhata chakra) fully. Backbends expose the most vulnerable front body, and mastering them is said to require surrendering fear. In the Ashtanga system, the three repetitions symbolize the practitioner's progressive deepening — each round invites greater opening and trust. Pattabhi Jois often emphasized that backbends are the most important part of the practice, and Sharath has continued to stress their transformative power.
