Abstract

A multipurpose exercise device has a portable construction, and is geometrically optimized with arcuate and planar surfaces to allow a safe and effective workout of the abdominal muscles when attached to the feet of a user. Furthermore, the device enables a user to efficiently transition from an oblique abdominal exercise to a core abdominal exercise in a highly efficient, hassle-free manner.

Claims

1. A multipurpose exercise device, comprising:

an arcuate surface opposite a non-arcuate end, wherein the arcuate surface meets the non-arcuate end at a first end region and at a second end region, and wherein the arcuate surface is curved in two orthogonal directions and has side-to-side curvature;

a first side opposite a second side, each side extending between the arcuate surface and the non-arcuate end to define a body; and

foot attachment means for securing and attaching a person'"'"'s feet to the first side, and for orienting the feet with toes pointed in a direction generally opposite the non-arcuate end.

2. The multipurpose exercise device of claim 1, wherein the arcuate surface comprises a friction enhancing material.

3. The multipurpose exercise device of claim 2, wherein the friction enhancing material comprises rubber.

4. The multipurpose exercise device of claim 1, further comprising weight retaining means for retaining weight on the second side.

5. The multipurpose exercise device of claim 1, wherein a cavity for receiving weight is in the body and is accessible from the second side.

6. The multipurpose exercise device of claim 5, wherein the weight comprises water.

7. The multipurpose exercise device of claim 5, wherein the weight comprises sand.

8. The multipurpose exercise device of claim 1, wherein the arcuate surface has a width in the range of about 8 to 24 inches.

9. The multipurpose exercise device of claim 1, wherein the arcuate surface has a width in the range of about 10-16 inches.

10. The multipurpose exercise device of claim 1, wherein the body has a length of about 16 to 36 inches.

11. The multipurpose exercise device of claim 1, wherein the body has a length of about 26 to 32 inches.

12. A multipurpose exercise device, comprising:

a body defined by an arcuate side, a first wall, a second wall and a straight end, wherein the first wall and the second wall converge radially from the arcuate side toward the straight end, and wherein the arcuate side meets the straight end at a first end region and at a second end region, and wherein the arcuate surface is curved in two orthogonal directions and has side-to-side curvature; and

foot retaining recesses in the first wall configured to secure and attach feet to the body and to orient the feet with toes pointed in a direction substantially opposite the straight end.

13. The multipurpose exercise device of claim 12, further comprising a weight retaining structure adjacent the second wall and configured to secure weight to the device.

14. The multipurpose exercise device of claim 13, wherein the weight retaining structure comprises a cavity accessible through the second wall for receiving weight.

15. The multipurpose exercise device of claim 14, wherein the weight comprises water.

16. The multipurpose exercise device of claim 14, wherein the weight comprises sand.

17. The multipurpose exercise device of claim 12, wherein a surface of the arcuate side comprises a friction enhancing material.

18. The multipurpose exercise device of claim 17, wherein the friction enhancing material comprises a rubber composite.

19. The multipurpose exercise device of claim 12, wherein the arcuate side has a width in the range of about 8 to 24 inches.

20. The multipurpose exercise device of claim 12, wherein the arcuate side has a width in the range of about 10-16 inches.

21. The multipurpose exercise device of claim 12, wherein the body has a length of about 16 to 36 inches.

22. The multipurpose exercise device of claim 12, wherein the body has a length of about 26 to 32 inches.
