A new and improved snow ski enhancer comprised of a weighted base having a front side, a back side, a left sidewall, a right sidewall, an upper surface and a lower surface. The front side has a lower bottom edge and an upper top edge. The upper surface is concave. The upper concave surface has a height ranging between three and five inches at the left sidewall. A height ranging between three and five inches at the right sidewall. A height ranging between two and three inches therebetween. The front side of the weighted base is inclined from the lower bottom edge to the upper top edge. Two hollow cylindrical vertical extensions are integral with the back side of the weighted base. The device contains a foam cushion having a top surface and a bottom surface. The bottom surface is secured to the upper concave surface of the weighted base. Three foot position markers are positioned on the top surface of the foam cushion. The foam cushion has a width ranging between two and three inches. The device contains a U-shaped piece having two lower legs and an intermediate extent therebetween. The two lower legs are adapted to be secured within the two hollow cylindrical vertical extensions of the weighted base. Two hand grips are located on the intermediate extent of the U-shaped piece.

A plaything for executing a reciprocating activity has a curved platform reciprocatably mounted on a base. The platform has a traveling surface with a longitudinally spaced, opposing pair of end ramps. A coaster can travel back and forth freely on the platform. The end ramps are inclined to cause reversion of the coaster.

An exercise machine which simulates snow skiing so as to especially develop the muscles of a person particular to snow skiing. A tubular support frame pivotally supports a pair of elongate foot support arms the front end of which are pivotally connected to the frame for multiple axes rotation. The rear end of the foot support arms each have a foot pedal which support the user in an elevated position. A pair of generally vertical pivot arms are pivotally connected at an upper end of each to the support frame with the lower end of each connected to a respective foot support arm. The pivot arms are interconnected by a tie bar for coordinated movement thereof. The movement of the foot support arms is simultaneously about multiple axes comprising lateral horizontal and upward vertical components wherein the foot support arms trace a conical path and the foot pedals trace generally upwardly directed arcuate paths with the foot support arms tilting inwardly to simulate edging of skis. Handle bars on a post which is pivotally attached to the frame and tie bar creates a lateral motion of the handle bars oppositely timed with the foot support arms for upper body balance and conditioning. A pair of damping cylinders or elastic bands add variable resistance during a workout.

A striding-type exercise device includes a unique upper body exercise arrangement. The exercise apparatus includes a frame having spaced upright support arms, two spaced pivotable leg members respectively pivotally mounted to the support arms for providing lower body striding movement and, two spaced, upwardly curved rails respectively mounted to the support members with two grip members respectively slidably mounted on the curved rails for providing upper body exercise. The leg members include platforms for receiving the feet of the user that is positioned between the spaced support members while the grip members are operative for receiving the hands of the user. The grip members are fashioned from a material which provides for a smooth sliding action on the rails. Resistance to movement of the grip members can be provided by physically squeezing the grip members, or alternatively, the grip members may further include a pocket for receiving a sheet of weighted material or a sheet of magnetic material, each of which provides active resistance to sliding movement of the grip members. In use, the leg members are pivotally reciprocated forwardly and rearwardly to simulate the natural stride of the legs during walking, while the grip members are slidably movable along the curved length of said rails to track the swinging arc of the user's arms during reciprocation of the arms. Alternatively, the leg members can be locked in position for use of only the upper body rails, or the user can grasp the handlebar to utilize only the lower body striding apparatus.

A miniature roll-up halfpipe for use with fingerboards or miniature skateboards includes a pair of sideframes configurable in either a collapsed compact configuration or an extended open configuration. A pair of platforms join the end portions of the sideframes to form a generally rectangular structure having a pair of upwardly open curved edges. A flexible resilient sheet is received upon the supporting frame to form a curved surface of the type frequently used by skateboarder's or the like. In the closed configuration, the flexible sheet is rolled into a cylindrical shape and encloses the collapsed siderails and platform elements. A pair of generally cylindrical endcaps are received upon the opposed ends of the rolled sheet to provide closure and secure attachment thereof.
