Have child lying on their belly (preferably a higher mat or on a bed so that one side of their body is along the edge of the bed/mattress and arm dangling down). With the dangling arm, hold it straight out 90 degrees (like a “T” if performing with both arms simultaneously), lower slowly towards ground and then raise back up. Perform 10x. Next, hold arm next to ear above head (as if raising arm); slowly lower down and then back up. Perform 10x. Finally, hold arm straight and out at an angle (45 degree angle from head; as if a “Y” if performing with both arms simultaneously) and slowly lower down towards ground, and then raise back up. Perform 10x. Make sure you perform 2 sets of 10 on each arm for each exercise.
