Conversely, it should be noted that there should be no break or pause between the arm reaching its fullest back– ward extension and the beginning of the throw. 4.-The throw is not started with a strong enough twist of the shoulders from right to left. The shoulder twist must be built up with appropriate body twisting from the hips exercises. There are some useful ones in Muller's System. Faults to be watched for in all Styles. s.-The javelin point is directed to the side instead of straight ahead in running and throwing. 6.-The body has passed the perpendicular forward before the delivery is made. 7.-Body breaks away from the javelin to the left.
