Abstract

An improved exercise device is used for a variety of exercises. In one embodiment, the exercise device has an upper portion having a contact surface. The contact surface has a partially hemispherical shape.

What is claimed is:  
     
         1 . An exercise device, comprising:
 an upper portion comprising a contact surface, wherein the contact surface comprises a partially hemispherical shape.   
     
     
         2 . The exercise device of  claim 1 , wherein the partially hemispherical shape comprises a semi-spherical shape. 
     
     
         3 . The exercise device of  claim 1 , wherein the contact surface is elastically deformable. 
     
     
         4 . The exercise device of  claim 1 , wherein the contact surface comprises leather, cloth, foam, rubber, or any combinations thereof. 
     
     
         5 . The exercise device of  claim 1 , wherein the contact surface comprises a textured surface. 
     
     
         6 . The exercise device of  claim 1 , wherein the upper portion comprises a body, and wherein the body is substantially rigid. 
     
     
         7 . The exercise device of  claim 1 , wherein the exercise device has a height from about 4 inches to about 8 inches and a width at a widest point from about 4 inches to about 8 inches. 
     
     
         8 . The exercise of device of  claim 1 , further comprising a bottom side. 
     
     
         9 . The exercise device of  claim 8 , wherein the bottom side is disposed on an opposing side of the exercise device from the contact surface. 
     
     
         10 . The exercise device of  claim 8 , wherein the bottom side is substantially flat. 
     
     
         11 . The exercise device of  claim 8 , wherein the bottom side comprises a friction increasing substantially flat surface. 
     
     
         12 . The exercise device of  claim 1 , further comprising a base. 
     
     
         13 . The exercise device of  claim 12 , wherein the base comprises a substantially cylindrical shape. 
     
     
         14 . The exercise device of  claim 12 , wherein the base comprises a hollow interior. 
     
     
         15 . The exercise device of  claim 12 , wherein the exercise device comprises a device interior, and wherein the device interior comprises an open section, further wherein the open section is disposed in a portion of the upper portion and a portion of the base. 
     
     
         16 . The exercise device of  claim 1 , wherein the exercise device comprises a solid interior. 
     
     
         17 . The exercise device of  claim 1 , wherein the contact surface has an exterior that is in about a same plane with a portion or all of an exterior of the upper portion on which the contact surface is not disposed. 
     
     
         18 . The exercise device of  claim 1 , wherein the contact surface extends outward beyond a plane in which a portion or all of an exterior of the upper portion is disposed. 
     
     
         19 . The exercise device of  claim 1 , further comprising a rotation base. 
     
     
         20 . The exercise device of  claim 19 , wherein the upper portion rotates in relation to the rotation base.
