Abstract:
1. A step platform for slow step exercises comprising: a basic structural block of lightweight styrene foam material having a predetermined generally rectangular outer peripheral configuration and including opposite sides that extend along a length of the basic structural block and opposite ends that extend along a width of the basic structural block, and upper and lower surfaces between which the sides and ends vertically extend; a plurality of upper openings formed in the upper surface of the basic structural block that are arranged to be aligned in at least one row extending in a lengthwise direction along the upper surface of the basic structural block; solid portions of the basic structural block disposed between each of the upper openings and the opposite sides of the basic structural block with the openings and solid portions being sized relative to each other so that sufficient surface area is provided along the upper surface of the basic structural block for bearing and distributing the load thereon generated during use thereof; and at least one flat step plate bonded or adhered to the upper surface of the basic structural block to cover the upper openings thereof with the flat step plate lacking projecting portions that are received in the upper openings so that the upper openings remain empty with the flat step plate bonded or adhered to the upper surface to allow for the step plate to flex when impacted during use, wherein the basic structural block includes lower openings formed in the lower surface to be vertically aligned with corresponding ones of the upper openings, and vertically extending portions of the styrene foam material of the basic structural block are disposed in vertical alignment with and between the upper and lower openings, and further comprising: a height adjusting block with a height adjusting function which is made of a material similar to the styrene foam material of the basic structural block and includes: a plurality of convex portions formed on the upper surface thereof so as to be respectively inserted and coupled to corresponding ones of the lower openings of the basic structural block; and a plurality of second concave portions formed on the bottom surface thereof by a plurality of second hollow holes formed at a position corresponding to a position directly below the plurality of convex portions so as to have a predetermined depth from the bottom surface.
