The eggbeater drill is a swimming technique primarily used in water polo and synchronized swimming. It involves a circular motion of the legs, resembling the action of an eggbeater, which helps swimmers maintain a stable position in the water while keeping their heads above the surface. This technique allows for efficient treading water and quick changes in direction. To perform the eggbeater drill, swimmers alternate the movement of their legs in a circular pattern, with one leg moving outward while the other moves inward. This motion provides both propulsion and balance, making it essential for athletes in sports like water polo and synchronized swimming.
