The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement. ## Claims ### Claim 1 An exercise machine, comprising: a frame having a first end, a second end, and a first rail; a carriage slidably positioned upon the first rail of the frame, wherein the carriage is adapted to support an exerciser; an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, wherein when the first run moves in a first direction the second run moves in a second direction that is substantially opposite of the first direction, and wherein when the first run moves in the second direction the second run moves in the first direction; a resistance device connected to the elongated member, wherein the resistance device applies a resistance force to the elongated member and the carriage in the second direction relative to the first run and wherein the resistance device applies the resistance force to the elongated member and the carriage in the first direction relative to the second run; wherein the resistance device is comprised of a spring; and a clutch connected to the carriage, wherein the clutch includes an engagement portion, wherein the engagement portion is adapted to selectively engage the first run and the second run of the elongated member, such that the carriage is configured to provide the resistance force to the exerciser in the second direction when the clutch is engaged to the first run, and the carriage is configured to provide the resistance force to the exerciser in the first direction when the clutch is engaged to the second run. ### Claim 2 (depends on 1) The exercise machine of claim 1, wherein the elongated member is comprised of an endless loop structure. ### Claim 3 (depends on 2) The exercise machine of claim 2, including a first wheel rotatably connected to the frame and a second wheel rotatably connected to the frame, wherein the elongated member is movably positioned upon the first wheel and the second wheel, wherein the first run and the second run are positioned between the first wheel and the second wheel. ### Claim 4 (depends on 3) The exercise machine of claim 3, wherein the resistance device is connected to the first wheel to apply the resistance force against rotation of the first wheel in a first rotational direction. ### Claim 5 (depends on 1) The exercise machine of claim 1, wherein the first run and the second run are substantially parallel with respect to one another. ### Claim 6 (depends on 1) The exercise machine of claim 1, wherein the first run and the second run are each horizontally aligned. ### Claim 7 (depends on 1) The exercise machine of claim 1, wherein the first run and the second run are each vertically aligned. ### Claim 8 (depends on 1) The exercise machine of claim 1, wherein the elongated member is comprised of a belt. ### Claim 9 (depends on 1) The exercise machine of claim 1, wherein the elongated member is comprised of a chain. ### Claim 10 (depends on 1) The exercise machine of claim 1, wherein the elongated member includes a plurality of teeth selectively engageable by the clutch. ### Claim 11 (depends on 10) The exercise machine of claim 10, wherein the plurality of teeth extend inwardly. ### Claim 12 (depends on 1) The exercise machine of claim 1, wherein the clutch is comprised of a linear clutch. ### Claim 13 (depends on 1) The exercise machine of claim 1, wherein the clutch includes an actuator connected to the engagement portion and adapted to linearly translate the engagement portion to a retracted position and an extended position, wherein the engagement portion includes a first end and a second end opposite of the first end, wherein the first end of the engagement portion is adapted to selectively engage the first run in the retracted position, and the second end of the engagement portion is adapted to selectively engage the second run in the extended position. ### Claim 14 (depends on 1) The exercise machine of claim 1, including: a first end platform connected to the frame, wherein the first end platform is near the first end of the frame; and a second end platform connected to the frame, wherein the second end platform is near the second end of the frame. ### Claim 15 (depends on 1) The exercise machine of claim 1, wherein the frame includes a second rail, wherein the second rail is parallel with respect to the first rail, and wherein the carriage is movably positioned upon the first rail and the second rail. ### Claim 16 An exercise machine, comprising: a frame having a first end, a second end, and a first rail; a carriage slidably positioned upon the first rail of the frame, wherein the carriage is adapted to support an exerciser; an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, wherein when the first run moves in a first direction the second run moves in a second direction that is substantially opposite of the first direction, and wherein when the first run moves in the second direction the second run moves in the first direction;
