A number of cones are placed as show on the drawing.
The number of cones are in accordance with the players abilities and condition.

The players now run as fast as possible (not necessarily sideways) from cone to cone.
Focus on the speed.

Take care that the players don't put the feet together before change of direction.
That is a normal thing to do, but slows the running down.
Instead the player must run to the cone and stop on the front leg.
The rear leg must then immediately after be directed against the next cone.
