摘要: A modular step exercise unit includes a plurality of individual steps. Each is in the form base having horizontal platform which comprises upper surface with depending sides forming an apron terminates plane parallel to so that can be placed directly on support surface, such as floor. The steps may made differing size during storage or even certain use conditions, are not being used stored within periphery largest step. multi-level formed by mounting smaller larger could abutting each other spaced from provide arrangement and If desired same would eliminate advantage storing non-use, but have providing more symmetrical equal sized
