Ardha Chandrasana is also called Half Moon Pose. It is so called because when the pose is assumed, the shape of the torso and the outstretched limbs resemble that of a crescent moon. This pose works on the various parts of the body such as the groins, thighs, knees, calves, ankles, abdomen, spine, chest and shoulders, and proves beneficial to the body in many ways.
Anjaneyasana is referred to as the Crescent Moon Yoga Pose. The posture is sometimes referred to as the Crescent Lunge Pose or Yoga Lunge Pose because the movement requires a slight forward lunge to achieve it perfectly.
