Abstract
An exercise device includes an elongate padded base upon which an exerciser reclines on his or her side to perform leg lifts. An "L"-shaped resistance bar is pivotally mounted to a side edge of the base, and includes a cross bar part that extends transversely with respect to the longitudinal axis of the base. The cross bar is positioned in longitudinally spaced apart relation to a foot end of the base so that the exerciser performs leg lifts by placing an ankle beneath the cross bar and alternately raising and lowering the cross bar against a resistance. The resistance may be set at differing levels by setting a pair of handles in a number of differing combinations of settings. Each handle is independently connected to a coiled spring and each handle has a plurality of resistance settings. The exerciser can therefore set the resistance at different levels by selecting unique handle positions.
