An exercise apparatus intended to primarily strengthen several or all of the major muscle groups of the body (i.e., in the arms, legs, chest, back, and/or abdomen) through repetitive body motion against elastic resistance. It typically consists of elastic bands, tubes, or cables often with handles/grips and sometimes anchors for attachment to fixtures (e.g., doors). The device typically enables the performance of a wide variety of exercise motions including curls, presses, lunges, flies, and raises; it may also be used to improve body flexibility and mobility.
