Abstract: A training device (b 10) for receiving thrown, hit or kicked balls includes a main frame (11) carrying a target frame (14) defining an open target area which is backed by a net (15). The size of the open target area is adjustable so that the user may practice with target areas of varying sizes. Adjustment of the target size is made possible by the provision of horizontal and vertical frame members, the horizontal frame members (23) being slidably adjustable on the vertical frame members (19). A plurality of spaced apart grooves (27) are placed along the vertical frame members (19) and an elastic ban or O-ring (28) is selectively placed in a groove (27) to hold the horizontal frame members (23) in a predetermined position.
