Twisting postures create a wringing effect on the abdominal organs. This helps to flush the liver and other organs, directing blood and lymphatic fluid into the larger vessels of the cardiovascular system, eliminating toxins. The abdominal muscles are the core prime movers in the twisting postures; however, depending on the pose there are other muscles that synergistically twist. For example, in twisting siddhasana, the sternocleidomastoid, latissimus dorsi, and triceps of one side assist the biceps and hamstrings of the other side to accentuate the twist.
