Latissimus dorsi (Lats), the broadest muscle of the back, is responsible for shoulder joint extension, adduction, transverse extension (also known as horizontal abduction), flexion from an extended position, and (medial) internal rotation. It also has a synergistic role in extension and lateral flexion of the lumbar spine.

Balasana, more commonly known as Child’s Pose, is a restful pose that not only stretches the Lats, but gently stretches your lower back, hips, thighs, knees, and ankles as well. Child’s Pose also helps relax your spine, shoulders, and neck while promoting blood circulation to the head.
