A constant resistance exercising apparatus and system comprising a series of resistance units, each comprising a storage drum, output drum, and a constant torque spring wound about each drum. Each resistance unit may be selectively actuated through a lever and clutch assembly that simply slides a gear arrangement in and out of contact with a respective output drum. Accordingly, through the effortless toggling of a lever, a user may select or deselect multiple resistance units to provide a desired quantitative and measurable level of constant resistive force. Exercise tools, including handgrips, leg cuffs, bars, and/or harnesses, may be connected to a cable extending from the resistance units, and thus, function as the interface between the exercising apparatus and the user.
