A step platform for aerobic exercise may include multiple layers. The top layer may include an elastic foam member that is configured to at least partially deform when stepped on by a user. The middle layer may include a rigid support member that is configured to at least partially maintain the shape of the foam member. The foam member may include a cover that wraps around the foam member and at least a portion of the support member to fasten the support member to the foam member. The bottom layer may include a base member having a support ridge configured to at least partially restrict deformation of the foam member in at least one direction. The base member may be connectable to the support member.

The step platform of claim 1, wherein the foam member comprises a moisture-resistant cover, wherein the moisture-resistant cover is configured to at least partially compress the foam member. 3. The step platform of claim 1, wherein the sides of the elastic foam member are tapered such that the length and width of the elastic foam member is approximately 3.5 or 7 inches shorter at an upper surface of the elastic foam member relative to a lower surface of the elastic foam member. 4. The step platform of claim 1 further comprising one or more risers connectable to the base member, the one or more risers having at least one ridge, wherein the base member comprises at least one groove configured to mate with the at least one ridge of the one or more risers. 5. The step platform of claim 1, wherein the contact surface of the tapered support ridge of the base member is further configured to at least partially restrict deformation of the foam member in at least two perpendicular axes. 6. The step platform of claim 1, wherein the contact surface of the tapered support ridge forms a closed-facing angle of about 20° to about 80° with the horizontal axis of the base member. 7. A bench for supporting a user during stepping exercise, the bench comprising: a foam member comprising a rigid portion with a stable exercise surface and an elastic portion with an unstable exercise surface, the elastic portion comprising an elastic material and the foam member having a plurality of exposed tapered sides that continuously taper from a lowermost edge of the foam member to an uppermost edge of the foam member;a support member connectable to a bottom surface of the foam member, the support member comprising a rigid material; anda base member connectable to at least a portion of the support member and at least a portion of the bottom surface of the foam member. 8. The bench of claim 7, wherein the foam member further comprises a moisture-resistant cover surrounding the elastic material. 9. The bench of claim 8, wherein the moisture-resistant cover comprises vinyl. 10. The bench of claim 8, wherein the foam member is configured to deform when stepped on by the user. 11. The bench of claim 7, wherein the elastic material comprises urethane foam, and the rigid material comprises plywood. 12. The bench of claim 7 further comprising one or more risers connectable to the base member, the one or more risers having at least one ridge, wherein the base member comprises at least one groove configured to mate with the at least one ridge of the one or more risers. 13. The bench of claim 7, wherein the base member comprises a support member, the support member being connectable to at least a portion of one or more side surfaces of the foam member. 14. The bench of claim 7, wherein the foam member has a plurality of pairs of exposed tapered sides that continuously taper from the lowermost edge of the foam member to the uppermost edge of the foam member. 15. A method of manufacturing a step platform for aerobic exercise, the method comprising: placing a support member into a recess formed by a bottom surface of a foam member such that the support member partially covers the bottom surface of the foam member, wherein the support member comprises a rigid material and the foam member comprises an elastic material, wherein the support member comprises a top surface, a bottom surface, and side surfaces, and the recess is configured to receive the top surface of support member and at least a portion of each side surface of the support member;covering at least a portion of the foam member and the support member with a moisture-resistant cover;sealing the moisture-resistant cover to the foam member in a fixed position such that the moisture-resistant cover forms to the one or more exposed surfaces of the foam member and at least partially compresses against the support member to fasten the support member to the foam member; andconnecting a top surface of a base member to the support member and at least a portion of the foam member and abutting one or more tapered support ridges of the base member against at least a portion of one or more side surfaces of the foam member such that the one or more tapered support ridges at least partially restricts deformation of the foam member in at least two axes. 16. The method of claim 15, wherein covering at least the portion of the foam member and the support member comprises covering a top surface of the foam member, one or more sides of the foam member, a portion of the bottom surface of the foam member, and a portion of the support member. 17. The method of claim 16, wherein at least partially compressing the foam member comprises sealing the moisture-resistant cover in a fixed position such that the moisture-resistant cover at least partially compresses the foam member against the support member.
