Requirements : 8 or more players, two balls, four cones.
Place cones in a square. Two girls stand at each cone (more if more than 8 players). P1 and P2 are diagonally opposite each other. P3 and P4 are in front on the other two cones and have the ball. P1 and P2 run towards each other, in the middle, they each receive a pass from their left. 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.
Points to remember : Always receive the ball from the left and throw straight ahead. 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.
