A has the ball and passes to B, who is in motion.
B performs the 3-step approach, passes to C and runs diagonally backward to C's place.
C performs the same movements as B but passes to D and runs diagonally backward to D's place.
Then D performs the same, but passes to E and runs diagonally backward to B's place.
From E the ball is returned through D's, C's and B's former positions until it reaches A and the exercise starts all over again.
