Massage roller

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.
