Open twists such as this are perfectly suitable and safe to do in pregnancy, as there is no restriction placed upon the uterus as would be in closed twists (therefore avoid closed twists during pregnancy).
Twists relieve stiffness in the back and also gently stretch muscles of the neck, chest, back and outer hips. Especially important is the gentle stretch of the rib and shoulder area, helping to relax upper torso and neck.
