Abstract: A lateral motion exercising apparatus provides a pair of vertically oriented axles engaged with a frame. A pair of support struts are rotationally engaged with the axles. A rigid link is pivotally joined at its terminal ends with the support struts in a manner for maintaining the support struts in parallel alignment as they rotate about the axles. A pair of platform struts is engaged pivotally at proximal ends of the support struts, the pivots enabling each of the platform struts to rotate vertically about its distal end. The proximal ends of the platform struts are constrained to move in opposing vertical motions in coordination with rotations of the support struts to produce a skating-like motion to a user standing on the platform struts.

Abstract: A pair of a skater foot supports are joined with a skating motion director including, a simple crank interconnected with the foot supports by a pivotal linkage, such that as the crank rotates in a circle, one of the foot supports is pulled and the other pushed during a first one-half of the circle rotation, while, the reverse occurs during the second one-half of the circle rotation. The crank is rotationally engaged with a flywheel through a mechanical drive train, enabling the flywheel to rotate at a speed greater than that of the crank whereby the foot supports move with a skating motion for exercising a skater.

Abstract: An apparatus for kick boxing training or punching, the apparatus comprising: a base portion providing a way of increasing the weight of the base portion; an upright portion removably and fixedly engagable with the base portion; and a cushion portion removably engagable with the upright portion and positioned for receiving hand and foot blows from an upright boxer. The base portion provides a circular base plate for resting the apparatus on a surface, and a circular sidewall, the sidewall joining the base plate in an outside radiused peripheral edge. The outside radiused peripheral edge is enabled such that a blow received by the cushion portion causes the apparatus to rotate about the radiused peripheral edge and to thereafter right itself.

Abstract: A boxing exercise apparatus is mounted on a stand. A pivoted support arm provides a strike absorbing means. In a first embodiment, the support arm is connected to the stand with a spring joined to a rigid rod. The rigid rod is preferably positioned in a neutral position with an integral positioning means. Displacement of the support arm away from the neutral position toward a rocked-back position is counteracted by the spring. In a second embodiment, the apparatus further includes a second spring joining segments of the stand so as to bias lateral movement of the support arm. When the support arm is deflected, the first spring and the second spring retards the motion of the support arm within two degrees of freedom. A friction adjustment is provided so as to adjust motion stiffness. This adjustment provides a novel approach using a friction washer.
