you take the arm back and just like in the transition of an overhead throw the arm first externally rotates (elbow leads arm forearm lays back) which then reverses into internal rotation as the elbow slows down and the forearm whips through. the IR starts between frame 2 and 3 of your sequence and the ER before that is an important loading move.
apologies, I have my rotations *** backwards, its late here! - have now corrected.
