Abdominal resistance device

1. A cycling system, comprising:

a cycle having a frame with a front end and a rear end;

a seat disposed on the frame between the front end and the rear end;

a resistance element having a first end and a second end; and

a harness releasably secured to the first end of the resistance element; and

a resistance element attachment point on the frame securing the second end of the resistance element to the frame at one of a plurality of points between the seat and the rear end of the frame.

2. The cycling system of claim 1 , wherein the resistance element is formed of an elastic material capable of returning to at least one of an original length and an original shape after being stretched.

3. The cycling system of claim 1 , wherein the first and second ends of the resistance element each include a retaining mechanism.

4. The cycling system of claim 1 , wherein the resistance element attachment point is integrated with the frame of the cycle.

5. The cycling system of claim 1 , wherein the resistance element attachment point is releasably affixed to the frame of the cycle.

6. A cycling system, comprising:

a cycle having a frame with a resistance element attachment point;

a resistance element; and

a harness releasably secured to the resistance element attachment point by the resistance element;

wherein the resistance element attachment point is releasably affixed to the frame of the cycle and further includes:

a rack having a length, the rack including:

a first rack portion and a second rack portion movable with respect to the first rack portion to change the length of the rack.

7. The cycling system of claim 6 , wherein the rack further includes a shelf configured to be movable with respect to at least one of the first rack portion and the second rack portion.

8. The cycling system of claim 7 , wherein a greater degree of tension is applied to the resistance element when the length of the rack is increased.

9. The cycling system of claim 8 , wherein:

the second rack portion is configured to extend distally away from and remain at least partially received within the first rack portion when the length of the rack is increased.

10. A method of performing abdominal exercise on a cycle, the method comprising:

mounting a cycle, the cycle being mounted by a cyclist;

securing a harness around the cyclist, the harness being coupled to a resistance element attachment point by a resistance element;

adjusting a level of tension applied to the resistance element; and

pedaling the cycle while the level of tension is being applied to the resistance element, wherein the resistance element attachment point includes a rack having a length;

a greater level of tension is applied to the resistance element by increasing the length of the rack; and

a lesser level of tension is applied to the resistance element by decreasing the length of the rack.

11. The method of claim 10 , wherein the resistance element has a first end and a second end opposite the first end, the first and second ends each including a retaining mechanism.

12. The method of claim 11 , wherein the first end of the resistance element is releasably affixed to the resistance element attachment point and the second end of the resistance element is releasably affixed to the harness.

13. The method of claim 10 , wherein the resistance element is formed of an elastic material capable of returning to at least one of an original length and an original shape after being stretched.

14. The method of claim 10 , further including:

performing an abdominal crunch while pedaling on the cycle.
