Set up 4 grids of about 8-10m by 5m. 3 players start on the first grid, working from one end to the other, covering the 5m distance. The aim is to stay in one straight line as they go up, and also keep themselves evenly spaced Once they have achieved that, they fall back into the next grid diagonally across and back. Now there should be 6 players on the line, and they all work together to come off the line, as one. Players continue working like this, until they reach the end of the grid. Once the coach blows his whistle the line may press off.
