Abstract: An apparatus and method provide an elastic resistance to a free-range of motion of a user. A cord running through a pulley and connected at either end to handles permits assisted resistance control (ARC) and a leverage advantage. In ARC, release by an anchor hand, still maintaining a load, may provide consistent or reduced force on the other, active, hand. One bodily member, such as a hand, may selectively halt and move as an “anchor” member, thereby simultaneously exercising itself and exerting control over another “active” bodily member operating in a “free range of motion.” Thereby, motion of the active hand may continue throughout a range desirable for a physical therapy regimen, a sporting activity, a work activity, or the like. A full range of motion of a bodily member and all supporting portions of the body is possible, without excessive stress or strain on joints due to a mismatch of position and load common to prior art systems.
