Abstract: Liquid-containing weighted device usable on land and/or in water and suitable for use in fitness, training, conditioning and/or rehabilitation. According to one embodiment, the device may include a closed receptacle, at least a portion of which may be transparent or translucent to permit a user to view its contents. The receptacle may be partially filled with a mixture of a liquid, such as water, and one or more insoluble solid materials, such as glitter and/or gravel. The mixture, when in motion, creates an inertia that provides an undertow reaction to assist with reverse movements to reduce or to eliminate kinetic joint load. In addition, as the mixture is in motion, the gravel scrapes against the inner surface of the receptacle, thereby enabling the device to create a rhythmic sound when being used, which may enhance its usability when a user is exercising to music.

Abstract: A new and improved flooring installation apparatus includes a clamping assembly for clamping onto a rigid structure below a floor board to be installed. The clamping assembly is capable of clamping onto the rigid structure at a bottom edge of the rigid structure. A handle assembly is pivotally attached to the clamping assembly. The handle assembly includes a pivoting portion for pivotally attaching to the clamping assembly. The handle assembly includes a lever arm portion connected to the pivoting portion. The handle assembly includes a handle grip connected to the lever arm portion. A board pusher assembly is connected to the lever arm portion of the handle assembly, such that, when the clamping assembly is clamped onto a rigid structure, and when a force is exerted on the handle grip in a direction toward a floor board, the board pusher assembly is capable of pushing against the floor board.

Abstract: An exercise device for has a rigid body defining a chamber, at least one first fluid mass disposed to move within the chamber in response to movement of the rigid body during exercise, thereby increasing the effective mass of the device by dynamic movement of the fluid mass during rhythmic exercise, one or more handles for gripping of the device during exercise, and a set of one or more weight adjusting elements that can be removably attached in order to adjust the static base weight of the exercise device. Exercise devices may be constructed for use of one hand or two hands.
