The 3 step drill is a great way to set up the javelin thrower into the power position, start with walking, then a more dynamic 3 step three. Finally, a variation of the 3 step throw can be used with a box. This helps the thrower drive up and out to step up the throw.
The walking 5 step drill in the javelin helps the javelin thrower work on proper footwork and javelin placement.
The focus on the 5 step drill in the javelin throw is to hit a good power position with a solid left side block. The right knee is driven up on the last right step to emphasize the upward movement that will occur once the javelin thrower moves across the runway at a faster pace.
