Coach Kouvolo breaks down the throwing launch sequence into several body positions:  A (Penultimate Step),  B (Block Step), C (Reverse C Bow Stretch), D (Hinge Delivery), E (Ride the Extended block leg), and F (Finish with 2 recovery steps).   The following videos of world record holder, Jan Zelezny,  illustrates each body throwing position.
