All positions have to be the back straight and positioned vertically. The neck is well positioned vertically, except as otherwise stipulated in the description of the exercise. Only to strain muscles, ensuring retention of poses, all the other muscles are relaxed as much as possible. In addition to sitting postures, pranayama can be performed standing (feet parallel to each other, are closed or slightly apart, arms hanging freely along the body, spine and neck erect) or lying in shavasana - corpse pose. To perform shavasana should lie on her back with her legs joined together, arms outstretched at your sides and palms pressed to the thighs. Then you must completely relax the body. Hands with the drop-down, legs slightly diverge in hand. In this position ensures maximum relaxation.
