Abstract:
1. A step exercise device, comprising: a. a rigid housing including a platform-supporting structure and a weight-module retaining structure on the exterior of the platform-supporting structure, wherein the weight-module retaining structure comprises an expanded dimension that creates a cavity between the weight-module and the weight-module retaining structure when the weight-module is coupled to the weight-module retaining structure; b. a platform surface formed of an elastomeric material configured to deform under body weight, coupled to the platform-supporting structure of the rigid housing; and c. at least one cylindrical weight-module configured to be selectively coupled within the weight-module retaining structure such that the weight-module is entirely within the platform-supporting structure, allowing the weight-module to be accessed and separated from the weight-module retaining structure while a user is stepping on the platform surface and also directly above the rigid housing.
