         2 . The exercise device according to  claim 1  wherein each of the front face surface portion, the rear face surface portion, the left end face surface portion, the right end face surface portion, the top face surface portion, and the bottom face surface portion is concave. 
     
     
         3 . The exercise device according to  claim 1  wherein a distance between the front face surface portion and the rear face surface portion is less that a distance between the left end face surface portion and the right end face surface portion. 
     
     
         4 . The exercise device according to  claim 3  wherein a distance between the top face surface portion and the bottom face surface portion is greater than the distance between the front face surface portion and the rear face surface portion and less than the distance between the left end face surface portion and the right end face surface portion. 
     
     
         5 . The exercise device according to  claim 4  wherein each corner portion has a partial or stretched dome shape. 
     
     
         6 . The exercise device according to  claim 3  wherein the distance between the front face surface portion and the rear face surface portion is between 3 and 4 inches. 
     
     
         7 . The exercise device according to  claim 3  wherein the distance between the front face surface portion and the rear face surface portion is between 3 and 4 inches. 
     
     
         8 . The exercise device according to  claim 7  wherein the distance between the left end face surface portion and the right end face surface portion is between 6 and 7 inches. 
     
     
         9 . The exercise device according to  claim 8  wherein the distance between the top face surface portion and the bottom face surface portion is between 5 and 6 inches. 
     
     
         10 . The exercise device according to  claim 1  wherein the block shaped body is made of a polymeric foam. 
     
     
         11 . The exercise device according to  claim 8  wherein the block shaped body is made of a polymeric foam or a natural rubber. 
     
     
         12 . An exercise device comprising:
 a block shaped body having a front concave face surface portion, a rear concave face surface portion opposite the front concave face surface portion, a left concave end face surface portion, a right concave end face surface portion opposite the left concave end face surface portion, a top concave face surface portion, a bottom concave face surface portion opposite the top concave face surface portion, and four convex corner portions each merging with a different set of at least three of the front concave face surface portion, the rear concave face surface portion, the left concave end face surface portion, the right concave end face surface portion, the top concave face surface portion, and the bottom concave face surface portion.   
     
     
         13 . The exercise device according to  claim 12  wherein a distance between the front concave face surface portion and the rear concave face surface portion is less than a distance between the left concave end face surface portion and the right concave end face surface portion. 
     
     
         14 . The exercise device according to  claim 13  wherein a distance between the top concave face surface portion and the bottom concave face surface portion is greater than the distance between the front concave face surface portion and the rear concave face surface portion and less than the distance between the left concave end face surface portion and the right concave end face surface portion. 
     
     
         15 . The exercise device according to  claim 14  wherein each corner portion has a dome shape. 
     
     
         16 . The exercise device according to  claim 12  wherein a distance between the front concave face surface portion and the rear concave face surface portion is between 3 and 4 inches. 
     
     
         17 . The exercise device according to  claim 13  wherein the distance between the front concave face surface portion and the rear concave face surface portion is between 3 and 4 inches. 
     
     
         18 . The exercise device according to  claim 17  wherein a distance between the left concave end face surface portion and the right concave end face surface portion is between 6 and 7 inches. 
     
     
         19 . The exercise device according to  claim 18  wherein a distance between the top concave face surface portion and the bottom concave face surface portion is between 5 and 6 inches. 
     
     
         20 . The exercise device according to  claim 12  wherein convex corner portions each has a curved or straight portion spacing the rear concave face surface portion from the front concave face surface portion giving each of the corner portions a stretched dome shape.
