Abstract

A hand-held exercise device includes left and right handles that rotate through respective paths about an axis that is centrally located between the handles. In one mode of operation, the device is rotated while walking to enhance aerobic exercise. In another mode of operation, a strap is secured between the device and at least one of a person'"'"'s lower limbs to link rotation of the device to movement of the person'"'"'s hands and at least one of the person'"'"'s lower limbs toward one another, thereby assisting the person in the performance of abdominal exercises and/or muscle stretching.

Claims

1. A method of performing an assisted abdominal exercise with a hand-held exercise device having a sheave that is rotatable about an axis, left and right handles connected to the sheave at diametrically opposed locations relative to the axis, and a flexible member having a first end portion secured to the sheave, and an opposite, second end portion releasably secured to one'"'"'s left and right feet, comprising the steps of:

grasping the handles in one'"'"'s respective left and right hands and lifting the sheave; and

while holding the sheave in space with the flexible member extending directly from the sheave to an opposite, second end portion of the flexible member that is secured to one'"'"'s left and right feet, rotating the sheave about the axis to wind the flexible member onto the sheave and pull one'"'"'s upper torso and said one'"'"'s feet toward one another.

2. The method of claim 1, wherein the rotating step is performed while lying on one'"'"'s back, contracting one'"'"'s abdominal muscles, and holding the sheave in space between one'"'"'s knees and one'"'"'s head.

3. The method of claim 1, wherein the rotating step is performed while lying on one'"'"'s back, contracting one'"'"'s abdominal muscles, and holding the sheave in space above one'"'"'s torso.

4. The method of claim 1, wherein the rotating step pulls the second end portion of the flexible member directly toward the sheave over a distance equal to how much of the flexible member is wound onto the sheave during the rotating step.

5. The method of claim 1, further comprising the step of while continuing to hold the sheave in space with the flexible member extending directly between the sheave and said one'"'"'s feet, rotating the sheave in an opposite direction about the axis to unwind the flexible member from the sheave and accommodate movement of one'"'"'s upper torso and one'"'"'s feet away from one another.

6. The method of claim 5, wherein the sheave is rotated in alternating first and second directions of rotation in synchronization with one'"'"'s performing (a) a sit-up exercise during winding of the flexible member about the sheave and (b) a reclining movement during unwinding of the flexible member from the sheave.

7. The method of claim 5, further comprising the step of relaxing one'"'"'s abdominal muscles to allow one'"'"'s thighs and one'"'"'s upper torso to move away from one another throughout rotation of the sheave in the opposite direction.

8. The method of claim 1, further comprising the step of exerting opposing axially directed forces through respective said handles during the rotating step.

9. The method of claim 1, further comprising the step of contracting one'"'"'s abdominal muscles to help pull one'"'"'s upper torso toward one'"'"'s feet throughout performance of the rotating step.

10. A method of performing an assisted abdominal crunch exercise with an exercise device having diametrically opposed left and right handles that rotate about a common axis, comprising the steps of:

linking rotation of the handles about the axis to variation in a common angle defined between one'"'"'s upper torso and one'"'"'s left thigh and between one'"'"'s upper torso and one'"'"'s right thigh;

grasping the handles in one'"'"'s respective hands and holding the device in space between one'"'"'s head and one'"'"'s knees; and

while continuing to perform the holding step and while maintaining one'"'"'s feet in a stationary position, pulling one'"'"'s upper torso toward one'"'"'s thighs by contemporaneously (a) rotating the handles in an angle reducing direction about the axis, and (b) contracting one'"'"'s abdominal muscles.

11. The method of claim 10, further comprising the step of also contemporaneously exerting opposing axially directed forces through respective said handles.

12. The method of claim 10, further comprising the step of while continuing to perform the holding step, moving one'"'"'s upper torso away from one'"'"'s thighs by contemporaneously (a) allowing the handles to rotate in an opposite, angle enlarging direction about the axis and (b) relaxing one'"'"'s abdominal muscles.

13. The method of claim 12, wherein the pulling step and the moving step are repeated in alternating fashion, resulting in performance of a set of abdominal crunch exercises.

14. The method of claim 12, further comprising the step of flipping the device one hundred and eighty degrees about a second axis that extends perpendicular to said axis, and switching one'"'"'s hands relative to the handles, thereby reversing each said direction of rotation.

15. The method of claim 10, wherein the rotating step is performed while lying on one'"'"'s back and holding the device in space above one'"'"'s torso.

16. The method of claim 10, further comprising the steps of flipping the device one hundred and eighty degrees about a second axis that extends perpendicular to said axis, and switching one'"'"'s hands relative to the handles, thereby reversing the angle reducing direction of rotation.

17. A method of performing assisted abdominal exercise with a hand-held device having a sheave that is rotatable about an axis, left and right handles connected to the sheave at diametrically opposed locations relative to the axis, and a flexible member having a first end portion secured to the sheave, comprising the steps of:

assuming a starting position relative to a support surface, with the flexible member extending directly from the sheave to an opposite, second end portion of the flexible member that is secured to one'"'"'s left and right feet, and with one'"'"'s back resting against the support surface;

grasping the handles in one'"'"'s respective left and right hands and lifting the device; and

while holding the device in space above the support surface, contracting one'"'"'s abdominal muscles and rotating the sheave about the axis to wind the flexible member onto the sheave and decrease a common angle defined (a) between one'"'"'s left thigh and one'"'"'s upper torso and (b) between one'"'"'s right thigh and one'"'"'s upper torso.

18. A method of performing an assisted abdominal crunch exercise with a hand-held exercise device having a sheave that is rotatable about an axis, left and right handles connected to respective, opposite sides of the sheave, wherein at least one of the handles is connected to the sheave at a radially displaced location relative to the axis, and a flexible member having a first end portion anchored to the sheave, and an opposite, second end portion releasably anchored in a fixed position proximate one'"'"'s left and right feet, comprising the steps of:

assuming an abdominal crunch position relative to a support surface;

grasping the handles in one'"'"'s respective left and right hands and lifting the sheave; and

while (a) holding the sheave in space with the flexible member extending directly between the sheave and the fixed position proximate one'"'"'s left and right feet, and (b) holding one'"'"'s left and right feet stationary, contracting one'"'"'s abdominal muscles and rotating the sheave about the axis, thereby winding the flexible member onto the sheave to help pull one'"'"'s upper torso toward one'"'"'s feet.
