17. Child’s Pose: This is another way to stretch the latissimus dorsi. Start on your hands and knees, then slowly bring your hips back until your forehead is on the floor. Arch your upper back and rotate your shoulders to stretch your lats and chest muscles. 18. Standing Calf Stretch: To work the soleus and gastrocnemius, perform this stretch on the edge of a stair step. Lightly rotate your ankles to stretch the calf muscles actively.
