Claim One:
1. A partially stabilized exercise device, comprising: a truncated sphere having a diameter in a range of approximately 40 to 80 centimeters, constructed to be deformable within a range of 1 to 15 percent under the weight of an average sized adult human, and wherein a diameter of said truncation is in a range of approximately a quarter to a half of the diameter of said sphere; a recess having four sides and a flat planar base insert located at the bottom of the recess within the truncated end of said truncated sphere; at least one elastic resistance member located within said recess and attached to at least two sides of said recess of said truncated sphere at three or more spatially separated points, said elastic resistance member extending along the perimeter of said recess; and a coupling assembly having multiple points of connection disposed on an end of the at least one elastic resistance member and the perimeter of said recess, wherein the coupling assembly secures the at least one elastic resistance member to the perimeter of said recess.
