How to do Ustrasana
Kneel on the yoga mat and place your hands on the hips.
Your knees should be in line with the shoulders and the sole of your feet should be facing the ceiling.
As you inhale, draw in your tail-bone towards the pubis as if being pulled from the navel.
Simultaneously, arch your back and slide your palms over your feet till the arms are straight.
Do not strain or flex your neck but keep it in a neutral position.
Stay in this posture for a couple of breaths.
Breathe out and slowly come back to the initial pose. Withdraw your hands and bring them back to your hips as you straighten up.
