Shoulderstand, or Salamba Sarvangasana, is an inversion that provides a deep stretch to the shoulders and neck. In this pose, particular attention should be paid to the neck area to avoid any 'crunching'. Props (such as a folded mat or blanket under the shoulders) are often used to help with alignment. This pose has many variations, such as bringing the legs into lotus. The Sanskrit name of the pose comes from sa: 'with', alamba: 'support', sarva: 'all', anga: 'limb', and asana: 'posture'.
