ABSTRACT:
The practice device has convexly rounded streamlined sides which flank a flat thinner center portion to provide hollows at each face which generally conform to the insides of the thighs of the user and is held between the thighs during arm stroke practice. During leg kick practice the sides of the device are held by the hands of the swimmer for use as a "kick board". Hand hold recesses can be provided on the sides to facilitate gripping during kick-board use, and the sides of the hollows can diverge to better conform to the configuration of the insides of the thighs.
