Requirements : 3 or more players (8-10 is a good number), 1 ball
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.
They then throw the ball to the person next to them and run in and defend that person who throws it to their neighbour who runs out to the middle.
Keep on going around until there are no drops, intercepts, bad passes. Ensure full concentration.
Points to remember : Concentrate on good passing technique!
Also useful as a general warmup.
