This is a simple dynamic warm-up arrangement where everyone on the team goes down and back at once.
This variation of the general dynamic warm-up is extremely simple and requires almost no set up at all. Basically have the players line up on one side of the grid and they all move down and back together.
Players perform dynamic movements to the cone on the opposite side, then perform a recovery run by jogging back to the start. (They can also perform dynamic movements back instead) Dynamic movements can include things like:
Once players learn the basic locomotions they can perform these exercises on their own without the help of a coach. This can potentially afford a coach some extra time while setting up other drills.
By the end of the warm-up the players should have broken a sweat. This ensures that the body is prepared for the activities to come and reduces the risk of injury.
