Another good exercise is what is called the Sarpasan , the position of the Snake. Deceptively simple, the child can lie on her stomach, flat on the ground, with her arms flexed at the elbow and hands by her shoulder. Slowly, ask her to breathe out, then lift her head and curve her back, so the head is bending towards the back. Then, with her breathing in, she can lift her feet, bent at the knees... ask her to bring her toes up, to touch her head. This is an excellent exercise for a supple back, strong abdominal muscles and a good digestion.
