RE: head stand

Firm the shoulder blades against your back and lift them toward the tailbone so the front torso stays as long as possible. This should help prevent the weight of the shoulders collapsing onto your neck and head.
Firm the outer arms inward, and soften the fingers. Continue to press the shoulder blades against the back, widen them, and draw them toward the tailbone. Keep the weight evenly balanced on the two forearms. It's also essential that your tailbone continues to lift upward toward the heels. Once the backs of the legs are fully lengthened through the heels, maintain that length and press up through the balls of the big toes so the inner legs are slightly longer than the outer.
