Medicine ball device

1. A medicine ball device, comprising:

a shell portion having an internal cavity formed therein and an outside surface;

a weight located in the internal cavity of the shell portion;

a pair of hand grips extending out of the shell portion from opposite sides thereof; and

a plurality of attachments accessible from outside of the shell portion, wherein the shell portion comprises two generally semi-spherical shell portions that are retained together by a strain band, which strain band includes the plurality of attachments, and wherein each semi-spherical shell portion has a flat end, a perimeter wall, internal ribbing, passageways for one of the pair of hand grips, and a groove formed around the perimeter wall that communicates with the flat end of each semi-spherical shell portion, wherein the strain band is positioned in the groove of each semi-spherical shell portion and retained thereto with fasteners, with the plurality of attachments extending exterior of the shell portion, thereby retaining the two semi-spherical shell portions together with the weight inside.

2. The medicine ball device of claim 1 , further comprising a pair of elongate loop handles extending out of the shell portion from opposite sides of the shell portion, which elongate loop handles pass through the medicine ball device.

3. The medicine ball device of claim 2 , wherein the elongate loop handles comprise a strap that engages with the weight to prevent the elongate loop handles from being pulled out of the medicine ball device.

4. The medicine ball device of claim 1 , wherein the strain band comprises a strap and wherein the plurality of attachments comprise looped sections of the strap that extends outside of an outer envelope of the shell portion.

5. The medicine ball device of claim 1 , wherein the pair of hand grips comprises a strap that passes through the medicine ball device through the passageways, and wherein the working length of the pair of hand grips is adjustable, and wherein pulling on one or both hand grips does not create a force which would tend to pull apart the two semi-spherical shell portions.

6. The medicine ball device of claim 1 , wherein the two semi-spherical shell portions each comprise an inner shell portion and an outer shell portion, the inner and outer shell portion being permanently connected together, wherein the inner shell portions are each formed of a material that is harder than a material forming the outer shell portions.

7. The medicine ball device of claim 1 , wherein the weight is generally spherical and is adapted to be snugly received in the internal cavity of the shell portion.

8. The medicine ball device of claim 1 , wherein the plurality of attachments are spaced apart on the outside of the medicine ball device.

9. A medicine ball device, comprising:

a shell portion having with an internal cavity formed therein and an outside surface;

a weight located in the internal cavity of the shell portion;

a pair of hand grips extending out of the shell portion from opposite sides thereof;

a pair of elongate loop handles extending out of the shell portion from opposite sides of the shell portion, which elongate loop handles pass through the medicine ball device and comprise a strap that engages with the weight to prevent the elongate loop handles from being pulled out of the medicine ball device; and

a plurality of attachments accessible from outside of the shell portion, wherein the shell portion comprises two generally semi-spherical shell portions that are retained together by a strain band, which strain band comprises a strap with a plurality of loops formed therein, the plurality of loops comprising the plurality of attachments accessible from outside of the shell portion.

10. The medicine ball device of claim 9 , wherein each semi-spherical shell portion has a flat end, a perimeter wall, internal ribbing, passageways for one of the pair of hand grips, and a groove formed around the perimeter wall that communicates with the flat end of each semi-spherical shell portion, wherein the strain band is positioned in the groove of each semi-spherical shell portion and retained thereto with fasteners, with the plurality of attachments thereof extending exterior of the shell portion, thereby retaining the two semi-spherical shell portions together with the weight inside.

11. The medicine ball device of claim 1 , wherein the pair of hand grips comprises a strap that passes through the medicine ball device through the passageways, and wherein the working length of the pair of handgrips is adjustable.

12. The medicine ball device of claim 9 , wherein the two semi-spherical shell portions each comprise an inner shell portion and an outer shell portion, the inner and outer shell portion being permanently connected together, wherein the inner shell portions are each formed of a material that is harder than a material forming the outer shell portions.
