How to do Sarvangasana?
Lie down flat on your back. Keep your legs close together and your chin tucked in.
Breathe deeply. Inhale. Lift your legs upwards till your feet are pointing directly up - that is, till your legs are perpendicular to your torso.
Tuck your hands underneath yourself with your palms facing up. With your hands under your buttocks, prepare to raise your torso.
Lift your torso gradually till you are resting on your shoulders.
Your arms must now be bent at the elbow. Bring your hands to your back to support yourself. Your legs should be over your head.
Slowly straighten your back.
Keep your knees firm but relax your calf muscles now. Maintain the posture.
To relax, lower your legs till your feet are at an angle of 45 degreesover your head. Lower your arms to the floor. Unwind gradually.
