determining the exercise footprint for the exercise assembly, wherein the exercise footprint is a floor area representing a space occupied by the exercise member when the exercise member is moved by the user and a space occupied by the user while the user operates the exercise assembly, wherein the exercise footprint extends outside of a floor area occupied by a frame supporting the exercise assembly; and controlling at least one illumination source to illuminate a floor surface to indicate at least a portion of the exercise footprint that extends outside of the floor area occupied by the frame. ### Claim 2 (depends on 1) The method of claim 1 wherein the at least one illumination source is mounted to the exercise assembly and projects light onto the floor surface. ### Claim 3 (depends on 2) The method of claim 2 wherein the floor surface is a floor piece that reflects light from the illumination source mounted to the exercise assembly. ### Claim 4 (depends on 1) The method of claim 1 further comprising turning on the illumination source while the exercise assembly is being operated by a user, and turning off the illumination source when the exercise assembly is not being operated by a user. ### Claim 5 (depends on 4) The method of claim 4 further comprising turning on the illumination source upon movement of the exercise member by the user. ### Claim 6 (depends on 1) The method of claim 1 wherein the floor surface comprises a floor piece containing the illumination source. ### Claim 7 (depends on 1) The method of claim 1 wherein the step of illuminating the floor surface includes providing a light pattern on the floor surface within the exercise footprint that indicates the movement of the exercise member within the space occupied by the exercise member when the exercise member is moved by the user. ### Claim 8 (depends on 1) The method of claim 1 further comprising adjusting the illumination source to change the illumination on the floor surface to correspond with changes in the exercise footprint. ### Claim 9 (depends on 1) The method of claim 1 further comprising illuminating the floor surface to indicate an entire boundary of the exercise footprint. ### Claim 10 (depends on 1) The method of claim 1 wherein at least a portion of the exercise footprint that extends outside of the floor area occupied by the frame is defined by is defined by the space occupied by the user while the user operates the exercise assembly. ### Claim 11 (depends on 1) The method of claim 1 wherein at least a portion of the exercise footprint that extends outside of the floor area occupied by the frame is defined by the space occupied by the exercise member when the exercise member is moved by the user. ### Claim 12 An exercise system that indicates an exercise footprint, the system comprising: an exercise assembly including: a frame, the frame occupying a floor area beneath the frame; at least one exercise member that is movable by a user; wherein the exercise footprint is a floor area representing the floor area beneath the frame and a space occupied the exercise member when the exercise member is moved by the user and a space occupied by the user operating the exercise assembly, wherein the space occupied by the exercise member extends outside of the floor area occupied by the frame of the exercise assembly; and an illumination source that illuminates a floor surface to indicate at least a portion of the exercise footprint defined by the space occupied by the exercise member that extends outside of the floor area occupied by the frame. ### Claim 13 (depends on 12) The system of claim 12 wherein the illumination source is mounted to the frame of the exercise assembly and projects light onto the floor surface. ### Claim 14 (depends on 13) The system of claim 13 wherein the illumination source includes at least one of an LED or a laser diode. ### Claim 15 (depends on 12) The system of claim 12 further comprising a floor piece positioned on and extending outside of the floor surface beneath the frame, the floor piece having the illumination source embedded therein. ### Claim 16 (depends on 12) The system of claim 12 further comprising a control unit that adjusts the illumination source to change the illumination on the floor surface in response to a change in the movement of the exercise member that changes in the exercise footprint. ### Claim 17 (depends on 12) The system of claim 12 wherein the illumination source receives power from the exercise assembly. ### Claim 18 (depends on 17) The system of claim 17 wherein the exercise assembly is powered by user-generated motion, and wherein the illumination source is only powered while the exercise assembly is being operated by a user. ### Claim 19 (depends on 12) The system of claim 12 wherein at least a portion of the exercise footprint that extends outside of the floor area occupied by the frame is further defined by the space occupied by the user while the user operates the exercise assembly; and wherein the illumination source illuminates the floor surface to indicate at least a portion of the exercise footprint defined by the space occupied by the user while the user operates the exercise assembly.
