P1 throws the ball to the player originally standing behind P2 and P2 to the player now standing in P1's original place. P1 and P2 each then run and stand behind the player they just threw the ball to. P3 and P4 then run. The cycle continues on the same. Players need to keep their eyes on the ball whilst keeping a feel of where other players are so there are no collisions.
All girls always stay on the same diagonal they started on.
If one player falls out of time, the whole drill is out. Start by walking through it a few times then build up speed. The players stand in a circle. One player starts off in the middle with the ball, passes to one of the people standing around in the circle, and runs and defends the person they threw the ball to. The person next to them runs into the middle of the circle and catches a pass from the person on the outside.
