Players start off with their own space on the court.
On the coach's first whistle players sprint on the spot, standing with wide feet and their arms outstretched as if defending.
Players sprint on the spot, with minimal leg raise - emphasis on fast feet.
On the coach's second whistle, players follow the coach's signal (right or left with their arm).
Players move in the crab position in the direction of the coach's signal until the third whistle.
Coach should vary the time between whistles and change direction several times.
