Massage roller

1. A massage roller comprising:

a single, generally elongated, cylindrical roller core having:

a first axial end, a second axial end, and a core length extending between the first and second axial ends;

a hollow core interior extending the core length and forming an inner core surface having an inner core radius and an inner core diameter twice the inner core radius;

an exterior core surface having an exterior core radius; and

a core thickness extending radially between the inner core surface and the exterior core surface; and

a roller body provided on the roller core comprising a plurality of curvilinear massage zones distributed substantially continuously, both radially and axially, on the exterior core surface, each massage zone having:

a selected one of a first softness and a second softness;

a substantially continuous, both radially and axially, massage surface having an exterior zone radius and an exterior zone diameter twice the exterior zone radius; and

a zone thickness extending radially between the exterior core surface and the massage surface;

wherein:

the sum of the core thickness and the zone thickness is less than the inner core radius; and

the core length is greater than the exterior zone diameter.

2. The massage roller of claim 1 wherein:

a first one of the massage zones has the first softness; and

a second one of the massage zones has the second softness.

3. The massage roller of claim 1 wherein:

the first softness is of predetermined softness; and

the second softness is softer than the first softness.

4. The massage roller of claim 1 wherein the roller body is further characterized as having:

a selected one of the first softness, the second softness and a third softness;

wherein:

a first one of the massage zones has the first softness;

a second one of the massage zones has the second softness; and

a third one of the massage zones has the third softness.

5. The massage roller of claim 4 wherein:

the first softness is of predetermined softness;

the second softness is softer than the first softness; and

the third softness is softer than the second softness.

6. The massage roller of claim 1 wherein:

a first one of the massage zones comprises a single generally rectilinear first structure curvilinearly conformant with the exterior core surface; and

a second one of the massage zones comprises a plurality of generally rectilinear second structures curvilinearly conformant with the exterior core surface, each of which is smaller in at least one curvilinear dimension that the first structure.

7. The massage roller of claim 4 wherein:

a first one of the massage zones comprises a single generally rectilinear first structure curvilinearly conformant with the exterior core surface;

a second one of the massage zones comprises a plurality of generally rectilinear second structures curvilinearly conformant with the exterior core surface, each of which is smaller in at least one curvilinear dimension that the first structure; and

a third one of the massage zones comprises a plurality of generally rectilinear third structures curvilinearly conformant with the exterior core surface, each of which is smaller in two curvilinear dimensions that the first structure.

8. The massage roller of claim 1 wherein the core length is on the order of about 12 inches.
