VIPARITAKARANI ( Inverted action pose )

Lie flat on your back, with your feet together and arms by your side. Press your palms down, raising your legs to a perpendicular position without bending the knees. Your palms should touch the waist. Then straighten your legs. The trunk should not make a right angle with the ground but simply an upward slanting position.
The chest should not press against the chin but be kept a little away. To return to the ground, bring your legs down slowly, evenly balancing your weight.
Through this asana, the muscles of the neck become stronger and blood circulation is improved. The functioning of the cervical nerves, ganglia and the thyroid also gets improved.
