The invention claimed is: 1. An exercise apparatus moveable between a storage mode and an exercise mode for use on a base surface by a user comprising: a frame for supporting a seat above the base surface comprising: a front leg; an engaging member pivotally connected to the frame comprising an engaging portion; and a rear leg comprising a receiving portion disposed to receive the engaging portion; a moveable backrest comprising: a resilient spine member with a first end connected to the frame; and a second end that is freely moveable; and a first flexible member disposed adjacent to the resilient spine member and captured by the backrest such that the first flexible member provides resistance to the user's movements, wherein said backrest is disposed to provide support to the user's back during movement of the backrest, and wherein the exercise apparatus can be stored substantially vertically and flat against a wall by suspending the exercise apparatus from a front or a back foot while in storage mode. 2. The exercise apparatus of claim 1, wherein the front leg and the rear leg are disposed substantially coplanar when the exercise apparatus is in the storage mode. 3. The exercise apparatus of claim 1, wherein the exercise apparatus is movable from the storage mode to the exercise mode by applying a single force. 4. The exercise apparatus of claim 3, wherein the single force used to move the exercise apparatus from the storage mode to the exercise mode moves the front leg and rear leg from a substantially coplanar position to a substantially non-coplanar position. 5. The exercise apparatus of claim 1, wherein the exercise apparatus is movable from the exercise mode to the storage mode in two steps. 6. The exercise apparatus of claim 5, wherein the two steps used to change the exercise apparatus from the exercise mode to the storage mode include disengaging the engaging member from the receiving portion of the rear leg and moving the front leg and rear leg to a substantially coplanar position. 7. The exercise apparatus of claim 1, wherein, in the storage mode, the exercise apparatus is low profile and compact, such that the exercise apparatus comprises a height of less than about four inches, a width of about seventeen and a half inches, and a length of about forty five and a half inches. 8. The exercise apparatus of claim 1, wherein, the exercise apparatus is fully assembled in storage mode. 9. The exercise apparatus of claim 1, wherein the second end of the backrest has a first motion in one of the following directions: torsional, forward, backward, or laterally with respect to the first end of the backrest if acted upon by one of the following: a threshold torsional force, a threshold forward force, a threshold backward force, or a threshold lateral force. 10. The exercise apparatus of claim 9, wherein the second end of the backrest has a second motion in one of the following directions: torsional, forward, backward, or laterally with respect to the first end of the backrest if acted upon by one of the following: a threshold torsional force, a threshold forward force, a threshold backward force, or a threshold lateral force. 11. The exercise apparatus of claim 10, wherein the first motion and the second motion of the second end of the backrest are different motions and occur simultaneously. 12. The exercise apparatus of claim 1, further comprising at least one pad that captures the resilient spine member. 13. The exercise apparatus of claim 1, further comprising a second flexible member disposed adjacent to the resilient spine member and captured by the backrest such that the second flexible member provides resistance to the user's movements. 14. The exercise apparatus of claim 1, further comprising a low profile handle attached to the backrest. 15. An exercise apparatus with a storage mode and an exercise mode for use on a base surface by a user comprising: a frame for supporting a seat above the base surface comprising: a front leg; an engaging member pivotally connected to the frame comprising an engaging portion; and a rear leg that is pivotally attached to the front leg such that the rear leg extends from the front leg at an angle comprising a receiving portion disposed to receive the engaging portion; a moveable backrest comprising: a resilient spine member with a first end connected to the frame and a second end that is freely moveable; at least one pad capturing the resilient spine member, wherein one of the at least one pads is attached to the frame; and a first flexible member disposed adjacent to the resilient spine member and captured by the backrest such that the first flexible member provides resistance to the user's movements, wherein said backrest is disposed to provide support to the user's back and neck during movement of the backrest. 16. The exercise apparatus of claim 15, wherein the front leg and the rear leg are disposed substantially coplanar in the storage mode. 17. The exercise apparatus of claim 16, wherein the exercise apparatus is moveable from the storage mode to the exercise mode by applying a single force. 18. The exercise apparatus of claim 17, wherein the single force used to change the exercise apparatus from the storage mode to the exercise mode moves the front leg and rear leg from a substantially coplanar position to a substantially non-coplanar position. 19. The exercise apparatus of claim 18, wherein the exercise apparatus is moveable from the exercise mode to the storage mode in two steps. 20. The exercise apparatus of claim 19, wherein the two steps used to change the exercise apparatus from the exercise mode to the storage mode include disengaging the engaging member from the receiving portion of the rear leg and moving the front leg and rear leg to a substantially coplanar position. 21. The exercise apparatus of claim 20, wherein, in the storage mode, the exercise apparatus is low profile and compact, such that the exercise apparatus comprises a height of less than about four inches, a width of about seventeen and a half inches, and a length of about forty five and a half inches. 22. The exercise apparatus of claim 21, wherein, the exercise apparatus is fully assembled in storage mode. 23. The exercise apparatus of claim 22, wherein the exercise apparatus can be stored substantially vertically and flat against a wall by suspending the exercise apparatus from a front or a back foot while in storage mode. 24. The exercise apparatus of claim 23, wherein the second end of the backrest has a first motion in one of the following directions: torsional, forward, backward, or laterally with respect to the first end of the backrest if acted upon by one of the following: a threshold torsional force, a threshold forward force, a threshold backward force, or a threshold lateral force. 25. The exercise apparatus of claim 24, wherein the second end of the backrest has a second motion in one of the following directions: torsional, forward, backward, or laterally with respect to the first end of the backrest if acted upon by one of the following: a threshold torsional force, a threshold forward force, a threshold backward force, or a threshold lateral force. 26. The exercise apparatus of claim 25, wherein the first motion and the second motion of the second end of the backrest are different motions and occur simultaneously. 27. The exercise apparatus of claim 26, further comprising at least one pad that captures the resilient spine member. 28. The exercise apparatus of claim 27, further comprising a low profile handle attached to the backrest. 29. An exercise apparatus with a storage mode and an exercise mode for use on a base surface by a user comprising: a frame for supporting a seat above the base surface comprising: a front leg; an engaging member pivotally connected to the front leg comprising an engaging portion; and a rear leg that is pivotally attached to the front leg by a pin joint such that the rear leg extends from the front leg at an angle in the range of about 100 degrees to about 110 degrees comprising a receiving portion disposed to receive the engaging portion; a moveable backrest comprising: a resilient spine member; a first end connected to the frame; a second end that is freely moveable; at least one elongate flexible member comprising flexible material to provide resistance to the movement of the user; and wherein said backrest is disposed to provide support to the user's back and neck during movement of the backrest; at least one pad capturing the resilient spine member and the at least one elongate flexible member, wherein one of the at least one pads is attached to the front leg; and a low profile handle that is attached to the second end of the backrest.
