Dandasana

Danda is the staff — and the pose is exactly that: the spine a straight rod above the folded legs. The modern practice made it the yardstick of all seated work, the pose that reveals whether a forward bend comes from the hips or is stolen from the back. The tradition knows the principle from its oldest instruction — sit erect, the three parts of the body in line — and dandasana is that instruction with nowhere to hide. It looks like nothing and asks for everything: a spine that holds itself up without props, as the sages'' seats have always required.

1. Sit with the legs extended straight in front, feet together, toes pointing up.
2. Sit on a folded blanket if the lower back rounds.
3. Place the hands beside the hips and press down, lifting the crown of the head.
4. Engage the thighs gently, flex the feet, and breathe steadily.
5. Hold for one to three minutes as posture training, or use it as the base for forward bends and twists.

Staff pose is an honest test of posterior-chain flexibility: tight hamstrings tip the pelvis back and round the lumbar spine, which is visible at a glance. Holding the upright position builds the deep postural muscles of the spine, and physiotherapists use it to retrain sitting posture for exactly this reason. Sitting on a folded blanket until the spine can rise on its own is the evidence-based approach, and the traditional one too.
