How to do Warrior 1
The sanskrit name for the yoga asana Warrior 1 is Virabhadrasana 1. This pose is named after the powerful War-Lord and hero Virabhadra - created by Siva from a lock of his matted hair.
In order to do this pose, first find a firm foundation - good alignment in your feet and legs. Begin standing on your mat, imagine there's a line down the middle of the mat, have your right foot on the imaginary line and facing forwards, have the heel of your left foot on the line with your foot turned in towards the mid-line.
To check out your alignment, bend your right knee a little and then create a push from your right foot and see if you can direct force all the way through your front leg, across the pelvis, through the back leg into your back foot. Adjust your feet a little if necessary, so that you feel the direction of force more clearly.
Now raise your arms and keep them apart. Breathe into your heart and lungs. Allow your chest to lift and open, your heart to lift and open, see if you can find energetic support from your heart and lungs for your arms, so they feel light. Now bring the palms of your hands together for the classical version of the pose. Breathe. Enjoy. And then repeat with your left foot forwards.
