Claim 21:
22. An exercise device comprising:
a body having:
a first side having a convex surface having a radius;
a second side opposing the first side, the second side having a concave area with a radius;
the convex surface of the first side connected at one end to the concave area of the second side by a first rounded end having a radius and connected at an opposing end by a second rounded end having a radius, wherein the radius of the first rounded end is larger than the radius of the second rounded end;
the center of the second rounded end is closer to the ground than the center of the first rounded end when the exercise device is at rest on its first side;
a width of the exercise device is less than the radius of the first side, wherein the width extends between a point at which a circle defined by the radius of the first rounded end meets a circle defined by the radius of the first side, and a point at which a circle defined by the radius of the second rounded end meets the circle defined by the radius of the first side;
the width is in the range of 600-1080 mm;
the circle defined by the radius of the first rounded end and the circle defined by the radius of the second rounded end each intersect the circle defined by the radius of the first side at their outer most points;
the circle defined by the radius of the first rounded end and the circle defined by the radius of the second rounded end do not overlap; and
a circle defined by the radius of the concave area of the second side meets each of the circles defined by the radius of the first rounded end and the radius of the second rounded end.
