Abstract: An exercise device for exercising the adductor and abductor muscles of the thigh portion of the legs without connecting the device to the legs in which a bar member is provided which can be placed below the thigh or above the knees to extend across the thighs or knees. Side members are provided to extend in the same direction down the inside or outside of the calf portion of the legs so that the device can then be used either for exercising in which the legs move outwardly or to be placed between the knees to provide resistance to inward movement of the thighs. In a preferred form of the invention the bar member is an elongate hollow member with a lid, with one side member permanently attached thereto and the other side member is movable back and forth from a rest position against a resistance force to exercise the adductor and abductor muscles without attachment of the device to the legs.
