Abstract:
A stepping apparatus comprising:a first predetermined number of steps comprising at least three steps, said steps forming a second predetermined number of directly adjacent pair combinations of said steps, each of said steps comprising distinct top surfaces thereof, said top surfaces being of different heights from one another above a common bottom plane of said steps; a plurality of different step height differentials equal to at least the sum of: said first predetermined number of steps, plus said second predetermined number of directly adjacent pair combinations of said steps, minus 1: said first predetermined number of steps being equal to six; said plurality of different step height differentials being equal to at least twelve: six of said at least twelve step height differentials defined by heights of said top surfaces of each of said six steps above said common bottom plane; and at least six others of said at least twelve step height differentials defined by height differences between said top surfaces of directly adjacent pairs of said six steps; wherein: said steps are sized and configured to support a user stepping thereon.
