Abstract: A pair of push up bars has a first supporting stand, a second supporting stand and a handle. The first sleeve of the first supporting stand and the second sleeve of the second supporting stand provide different assembly depths. The handle is the long arm and the short arm of unequal length, which are combined with the first and second supporting stand respectively, so that the handle and the first and second supporting stand can be arbitrarily matched to have different use angles and states to improve the variability of the structure. It is only necessary to replace the first and second supporting stand with each other, which adds the convenience of structural change.

Abstract: A rhythm fitness step apparatus includes a body and two leg bases. The body has an upper surface and a lower surface, wherein the upper surface is installed with a platform thereon; both sides of the lower surface are formed with an installation space separately. The installation space has a plurality of slots and a plurality of dodge slots concavely and alternately installed therein, wherein the concave depth of the slot and the concave depth of the dodge slot are different so that the depth of the dodge slot is greater than the depth of the slot in design. The leg base has a plate body. The lower surface of the plate body is installed with a cushion pad; the upper surface of the plate body has a plurality of first supporting blocks and a plurality of second supporting blocks protruding therefrom alternately and corresponding to the configuration layout of the slots and the dodge slots of the body. The distance of the second supporting block protruding from the upper surface of the plate body is larger than that of the first supporting block protruding from the upper surface of the plate body so that the setting between every first supporting block and every second supporting block is in the form of a stair shape with a difference in height.
