9. The device of claim 1 , wherein the platform rotates 360° about the axis.

10. The device of claim 1 , further comprising:

a strut connected to the first end of said track by at least one strut hinge; and

a knee pad removably connected to said strut.

11. The exercise device of claim 1 , wherein the support surface of said platform includes a raised backrest.

12. An exercise device, comprising:

a straight track comprising a first end and a second end;

a track carriage disposed on and movable in a first plane along said track said track carriage including a first handle on each of two sides of said track carriage extending widthwise with respect to said track;

a resistance system selectively engageable with said track carriage to provide variable resistance to movement of said track carriage along said track;

a platform having a support surface adapted to support a user of the device, wherein said platform is rotatably secured to said track carriage such that said platform rotates left and right relative to said track carriage, in a second plane substantially parallel to the first plane, about an axis that is perpendicular to said track;

a bracket on the second end of said track;

a vertical support including a plurality of support positions each adapted to support said bracket for varying a height of the second end of said track relative to the first end of said track;

at least one second handle fixed adjacent to the second end of said track; and

at least one arm support pad adjacent to the at least one second handle.

13. An exercise device, comprising:

a track comprising a first end and a second end;

a track carriage disposed on and movable along said track;

a resistance system selectively engageable with said track carriage to provide variable resistance to movement of said track carriage along said track;

a platform adapted to support a user of the device secured to said track carriage;

a foot pad removably securable adjacent the first end of said track, wherein said foot pad includes at least one surface oriented perpendicular to said track wherein said foot pad is removably securable adjacent the first end of said track using at least one post;

a strut connected to the first end of said track by at least one strut hinge; and

a knee pad removably connected to said strut;

wherein said track carriage further comprises at least one handle.

14. The device of claim 13 , wherein said resistance system comprises at least one elastic member, wherein the elastic member provides resistance against movement of said track carriage away from the first end of said track.

15. The device of claim 13 , wherein said strut is connected to the first end of said track by two strut hinges.

16. The device of claim 13 , further comprising:

a bracket connected to the second end of said track;

a vertical support comprising a plurality of support positions each adapted to support said bracket for varying a height of the second end of said track relative to the first end of said track;

a support lock pin for engaging at least one of the plurality of support positions; and

a pivot lock pin for engaging said bracket to inhibit movement of said bracket relative to said track.

17. The exercise device of claim 13 , wherein said platform is rotatably secured to said track carriage such that said platform rotates left and right relative to said track carriage about an axis that is perpendicular to said track.

18. The device of claim 13 , further comprising at least one second handle fixed adjacent to the second end of said track.

19. The device of claim 18 , further comprising at least one arm support pad adjacent to the at least one second handle.

20. An exercise device, comprising:

a straight track comprising a first end and a second end;

at least one first handle adjacent to the second end of said track;

a track carriage disposed on and movable along said track;

a resistance system selectively engageable with said track carriage to provide variable resistance to movement of said track carriage along said track, wherein said resistance system comprises at least one elastic member and wherein the elastic member provides resistance against movement of said track carriage away from the first end of said track;

a platform adapted to support a user of the device, rotatably secured to said track carriage such that the platform rotates left and right relative to said track carriage about an axis that is perpendicular to said track;
