## Abstract

An exercise device includes a flat base having a first end and an opposing second end. The base is configured to engage a flat exercise surface. The exercise device further includes a pair of opposing sidewalls extending away from the base and an arcuate upper surface extending between the first end and the second end between the pair of opposing sidewalls. A first angle is defined between the base and the upper surface proximate the first end and a second angle is defined between the base and the upper surface proximate the second end. The exercise device also includes a coccyx cutout in the upper surface proximate at least one of the first end and the second end.

## Claims

### Claim 1

An exercise device comprising:
a flat base comprising a first end and an opposing second end, said flat base configured to engage a flat exercise surface;
a pair of opposing sidewalls extending away from said flat base;
an arcuate upper surface extending between a first edge of said first end and a second edge of said opposing second end between said pair of opposing sidewalls, a first angle defined between said flat base and said upper surface proximate said first end, a second angle defined between said flat base and said upper surface proximate said opposing second end; and
a first coccyx cutout in said upper surface proximate said first end and extending to said first edge, and a second coccyx cutout in said upper surface proximate said opposing second end and extending to said second edge, wherein said first coccyx cutout extends completely through said exercise device and said second coccyx cutout extends only partially through said exercise device.

### Claim 2 (depends on 1)

The exercise device of claim 1, wherein said first angle being different than said second angle.

### Claim 3 (depends on 1)

The exercise device of claim 1, wherein said first angle and said second angle are equal.

### Claim 4 (depends on 1)

The exercise device of claim 1, wherein said first and second angles are in a range of 15° to 60°.

### Claim 5 (depends on 1)

The exercise device of claim 1, wherein said pair of opposing sidewalls extends away from said flat base substantially orthogonally.

### Claim 6 (depends on 1)

The exercise device of claim 1, wherein said pair of opposing sidewalls extends away from said flat base angled towards each other.

### Claim 7

An exercise device comprising:
a flat base comprising a first end and an opposing second end, said flat base configured to engage a flat exercise surface;
a first inclined surface extending from said first end towards said opposing second end;
a second inclined surface extending from said opposing second end towards said first end;
an upper surface approximately midway between said first end and said opposing second end, said upper surface configured to join said first inclined surface and said second inclined surface in at least one of an arcuate transition and a linear transition; and
a first coccyx cutout configured to receive a coccyx area of a user and extending through said first inclined surface and a second coccyx cutout extending through said second inclined surface;
the first coccyx cutout in said upper surface proximate said first end and extending to said first edge, and the second coccyx cutout in said upper surface proximate said opposing second end and extending to said second edge, wherein said first coccyx cutout extends completely through said exercise device and said second coccyx cutout extends only partially through said exercise device.

### Claim 8 (depends on 7)

The exercise device of claim 7, wherein said first inclined surface is inclined with respect to said flat base at a first angle and said second inclined surface is inclined with respect to said flat base at a second angle, said first angle different than said second angle.

### Claim 9 (depends on 7)

The exercise device of claim 7, wherein said first inclined surface is inclined with respect to said flat base at a first angle and said second inclined surface is inclined with respect to said flat base at a second angle, said first angle and said second angle are equal.

### Claim 10 (depends on 7)

The exercise device of claim 7, wherein said first inclined surface is inclined with respect to said flat base at a first angle and said second inclined surface is inclined with respect to said flat base at a second angle, said first and second angles in a range of 15° to 60°.

### Claim 11 (depends on 7)

The exercise device of claim 7, further comprising a pair of opposing sidewalls extending away from said flat base substantially orthogonally.

### Claim 12 (depends on 7)

The exercise device of claim 7, further comprising a pair of opposing sidewalls extending away from said flat base angled towards each other.

### Claim 13

An abdominal exercise device comprising:
a base configured to engage an exercise surface, said base comprising a first end comprising a first edge and an opposing second end comprising a second edge;
a pad member coupled to said base, said pad member extending from said first edge to said second edge, said pad member comprising a thickness that varies between said first end to said opposing second end; and
a first coccyx cutout extending through said pad member from said first edge toward said second edge and a second coccyx cutout extending through said pad member from said second edge toward said first edge, and wherein the first coccyx cutout extends completely through said abdominal exercise device and said second coccyx cutout extends only partially through said abdominal exercise device.

### Claim 14 (depends on 13)

The abdominal exercise device of claim 13, wherein said base is rigidly flat.

### Claim 15 (depends on 13)

The abdominal exercise device of claim 13, wherein said thickness is continuously variable between said first end to said opposing second end.
