Abstract: The combination limb and abdominal exerciser of the present invention has a first torsional spring coupled between two rods of a set of pivotally connected rod members, such that the expansion or compression of the first torsional spring provides an exercise resistance when the two rods are moved outward away from or moved inward closer to each other by an external force, and the two rods return by the resilience of the first torsional spring when the external force is released, so as to help a user to exercise the upper limbs or exercise the lower limbs. Furthermore, a handle can be axially disposed at the end of each of the two rods, and a second torsional spring is disposed between each handle and the corresponding rod. The user can hold the handles and make the rods to rotate with respect to each other for wrist exercise.

Abstract: A multi-purpose surfing balancer including a base plate, a resilient rubber body, a step-on board, and a central pole. A bottom surface of the rubber body being fixed to a middle of a top of the base plate. The top of the base plate being fixed to a middle of a bottom of the step-on board. The central pole being fixed to the surface of the step-on board for a user to stand on the step-on board with both feet splitting over both ends of the resilient rubber body in position to practice balancing or surfing by the support of the resilient rubber body and swing motion controlled by the user.

Abstract: A multi-purpose surfing balancer is comprised of a base plate, a resilient rubber body, a step-on board, and a central pole; wherein, the bottom surface of rubber body being fixed to the middle of the top of the base plate; the top of the base plate being fixed to where at the middle of the bottom of the step-on board; the central pole being fixed to the surface of the step-on board for the user to stand upon the step-on board with both feet splitting over both ends of the resilient rubber body in position to practice balancing or surfing by the support of the resilient rubber body and swing motion controlled by the user.

Abstract: A rotating play device capable of training wrist coordination has a main body of a semi-spherical cage frame braided by the bar skeleton with several ring rails of different breadths formed respectively along the looping ring portions on the spherical surface, crossed and connected on the top surface of the cage frame by several radial and longitudinal rails. A holding cover is mounted on the top surface of the cage frame for the user to hold by finger holes formed in the holding cover. When in use, a ball is placed in the cage frame, and the user holds and rotates the main body of the device by controlling the strength of the wrist and the arm to make the ball roll inside the main body via centrifugal.

Abstract: A multi-purpose sliding exerciser including a base made of two boards butted and hinged to each other. The hinge joint is threaded with a plurality of elastic ropes. At each end of the base is a tension rope. A plurality of insertion holes are also provided in pairs on the base to restrict the pedals' slide path. The multipurpose sliding exerciser allows the user to remove the elastic ropes threaded through the back side of the base so as to fold up the boards for easy storage or transport.
