发明名称 Modular aerobic-exercise stepper
摘要 A stepper for use during aerobic stepping exercises. The invention has modular platforms that allow for one or more platforms to be stacked upon a base platform. The platform is placed on the base in a pyramid-like manner forming steps in every direction surrounding the stepper so that the user may step from one platform to another in any direction. Interlocking slots and ridges are formed on opposing surfaces of each platform and the base to provide stability during use. A non-slip coating on all opposing surfaces and on the step surfaces to provide additional stability. An optional one-piece cap is provided as a top surface which is also non-slip.
