1. An adjustable stepping structure for aerobic exercise, comprising: a substantially rectangular platform having a top surface for stepping, sidewalls and endwalls, said sidewalls being laterally longer than said endwalls; andat least one support element having an upper portion and a base, said base extending laterally outward from said upper portion;wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the at least one support element, with the upper portion of the support element formed to nest within a lower interior portion of the platform between said sidewalls and endwalls;wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first endwall of the platform on the floor surface and a second endwall of the platform into a notch formed into the upper portion of the support element;wherein the platform can be supported in a second angled orientation relative to the floor surface by placing a first sidewall of the platform on the floor surface and a second sidewall of the platform into said notch; andwherein a first angle of the top surface with respect to the floor surface in the first angled orientation is less than a second angle of the top surface with respect to the floor surface in the second angled orientation. 2. The adjustable stepping structure of claim 1, wherein the support element further comprises at least one ledge portion, said ledge portion extending outward from said upper section and upward from said base. 3. The adjustable stepping structure of claim 2, wherein said platform further comprises at least one opening in said sidewall or said endwall, said opening being sized to receive said ledge portion and align said support element relative to said platform when said platform is placed upon said support element in the horizontal orientation. 4. The adjustable stepping structure of claim 3, wherein the support element comprises at least two ledge portions, a first one of said ledge portions having a different profile than a second one of said ledge portions;wherein said platform comprises at least two openings in said sidewall or said endwall, a first one of said openings being sized to receive said first ledge portion, a second one of said openings being sized to receive said second ledge portion. 5. The adjustable stepping structure of claim 1, wherein said notch has a profile to inhibit said sidewall and said endwall from slipping out of said notch when said platform is placed in either one of said angled orientations. 6. The adjustable stepping structure of claim 1, wherein said notch has an arcuately curved profile. 7. The adjustable stepping structure of claim 1, wherein said sidewalls and said endwalls have a lower rounded edge. 8. The adjustable stepping structure of claim 1, wherein said lower round edge has comprises a non-slip surface. 9. A support element for supporting an aerobic exercise platform, said support element comprising: a generally rectangular upper portion;a base extending laterally outward from the upper portion; andat least one notch forming a downward indentation in the upper edge of the upper portion;wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the support element, wherein the upper portion of the support element is formed to nest within a lower portion of the platform;wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first endwall of the platform on the floor surface and a second endwall of the platform into the notch; andwherein the platform can be supported in a second angled orientation relative to the floor surface by placing a first sidewall of the platform on the floor surface and a second sidewall of the platform into the notch. 10. The support element of claim 9, wherein said notch has an arcuately curved profile. 11. The support element of claim 9, wherein said notch comprises a non-slip surface. 12. The support element of claim 9, wherein said upper portion of said support element is formed to nest within the base of an upper adjacent support element. 13. The support element of claim 9, wherein the base comprises sidewalls and endwalls defining a lower interior cavity for receiving the upper portion of a lower adjacent support element. 14. The support element of claim 13, wherein said base is sized to support the bottom ends of the sidewalls and endwalls of an upper adjacent support element. 15. The support element of claim 9, further comprising: at least one ledge portion, said ledge portion extending outward from said upper portion and upward from said base. 16. The support element of claim 9, further comprising: at least one opening in said base, said opening being sized to receive said ledge portion and align said support element relative to a lower adjacent support element when said support element is placed upon said lower adjacent support element. 17. The adjustable stepping structure of claim 16, wherein the support element comprises at least two ledge portions, a first one of said ledge portions having a different profile than a second one of said ledge portions;wherein said platform comprises at least two openings in said sidewall or said endwall, a first one of said openings being sized to receive said first ledge portion, a second one of said openings being sized to receive said second ledge portion. 18. An adjustable stepping structure for aerobic exercise, comprising: a substantially rectangular platform having a top surface for stepping, sidewalls and endwalls, said sidewalls being laterally longer than said endwalls; andat least one support element having an upper portion and a base, said base extending laterally outward from said upper portion;wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the at least one support element, with a lower portion of the platform having a cavity formed to receive the upper portion of the support element;wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first endwall of the platform on the floor surface and a second endwall of the platform into a notch formed into the upper portion of the support element;wherein said notch has an arcuately curved profile;wherein the platform can be supported in a second angled orientation relative to the floor surface by placing a first sidewall of the platform on the floor surface and a second sidewall of the platform into said notch; andwherein a first angle of the top surface with respect to the floor surface in the first angled orientation is less than a second angle of the top surface with respect to the floor surface in the second angled orientation. 19. The adjustable stepping structure of claim 18, wherein said notch comprises a non-slip surface. 20. The adjustable stepping structure of claim 18, wherein the support element further comprises at least one ledge portion, said ledge portion extending outward from said upper section and upward from said base; andwherein said platform further comprises at least one opening in said sidewall or said endwall, said opening being sized to receive said ledge portion and align said support element relative to said platform when said platform is placed upon said support element in the horizontal orientation.
