Abstract: An exercise device comprising a pneumatic hand pump with a valve in the exhaust port. The hand pump is pivotally attached to a folding metal chair or, in an alternate embodiment, to an elongated step board for easy use and storage and provides exercise and muscle toning when pumped against a strong force caused by a nearly closed valve in the exhaust port.

Abstract: An exercising dumbbell comprising a tubular body with attached "U" shaped handle for use with two hands. The body contains a D.C. motor which is geared to a stationary central shaft and which may rotate around the shaft to generate strong vibrations. Batteries are contained within the handle and motor speed is varied from zero to maximum by pressure activated switches under each hand. Function switches on the body reverse motor direction, permit one-hand, both-hand or hands-free operation, provide music through an included speaker, and generate an exhilarating train of pulses.

Abstract: A ventilation structure for a shoe having a sole portion and a connected upper portion utilizing an aperture or slit that is formed through the upper portion of the shoe. The aperture extends along a dimension of the upper portion of the shoe and is overlain with a mesh layer connected to the upper portion of the shoe. A closure, such as a zipper, shuts at least a portion of the aperture and blocks at least a portion of the mesh layer from passage of air from the exterior to the interior of the shoe. The toe portion of the shoe may be further provided with an opening overlain with mesh that is openable or closable with a flap.
