A weight apparatus includes a handle, first and second anchorages mounted to first and second ends of the handle, respectively, the handle and the first and second anchorages having an axially extending opening, first and second rods axially movable inside the axially extending opening and adapted to be moved axially relative to the axially extending opening in opposite directions upon rotation of first and second pinion gears in the first and second anchorages, respectively, that engage with first and second racks on the first and second rods, respectively, and a lock having a locked condition in which rotation of the first and second pinion gears is prevented and an unlocked condition in which rotation of the first and second pinion gears is permitted.

System and methods are disclosed which include exercise equipment with magnetic portions. The magnetic portions may be incorporated into equipment or into additional weights for use with the equipment. The presence of the magnetic portion allows a user to change weights during exercise in a quick, easy, convenience, and safe manner.

A dumbbell and barbell supporting system includes two tables movable toward and away from each other and each having a plate, a casing and a bracket disposed on each of the plates and the bracket being movable and rotatable relative to the casing, two dumbbells disposed on the tables and each including two weight members and two weight elements disposed on the bracket and the casing, and two handlebars engageable with the weight members and the weight elements, the weigh members are movable toward each other, and the weight elements also movable toward each other, and a longitudinal bar is engageable with the weight members and the weight elements for acting as a barbell device.

An exercise dumbbell that is configured to be manufactured from a sustainable material and further configured to provide alternate weight configurations. The present invention includes a support bar member that is manufactured from bamboo having a hollow passage extending therethrough. An internal support rod is present within the support bar member and extends the length thereof. Opposing ends of the internal support rod are configured to receive fasteners thereof so as to secure a first weight member and a second weight member. The first weight member and the second weight member are manufactured in a preferred embodiment from natural stones. In a preferred embodiment the first weight member and the second weight member have different weights. The first weight member and second weight member include recesses formed on the surface thereof operable to receive a portion of the ends of the support bar member.

An adjustable dumbbell includes weight plates that are selectively connectable to a handle. Unselected weight plates are secured to a cradle. To secure the unselected weight plates to the cradle, a latch in the cradle is inserted into an engagement surface notch in the weight plate. The unselected weight plates are individually actuated based on which weight plates are selected and connected to the handle.

The present invention relates to a fast-load weight plate system, wherein a weight plate, a linkage assembly and a stop block are provided. The weight plate is provided with a radially arranged straight slot that runs from the middle of the weight plate to its outer edge, The stop block is attached to the weight plate and blocks the straight slot; one end of the linkage assembly is movably connected to the handle of the weight plate and the other end is rotatably connected to the stop block. The linkage assembly is used to rotate the stop block to unblock the straight slot; such arrangement promises an easy loading and unloading process that takes up less space.

A dumbbell apparatus which is adapted with a series of weight plates, the number of which can be safely and reliably adjusted with a single simple motion. The apparatus comprises a cradle for storing and deploying the apparatus, weight plates, and a handle apparatus which has two spline bolts which support the weight plates and are used to simultaneously be adjusted by means of an adjusting pin which moves the spline members together through a motion transmitting gear. The apparatus may be further enhance with permanent weights and gripping options.

A dumbbell may include a handle, a first weighted portion and a second weighted portion, wherein the first weighted portion has a first cap and a first receiving space to receive one or more weighted units therein, and the second weighted portion has a second cap and a second receiving space to receive one or more weighted units therein. In one embodiment, the handle has a first threaded portion and a second threaded portion located at two opposite ends of the handle, and the first threaded portion is configured to threadedly engage with a first cap to secure the weighted units in the first receiving space, while the second threaded portion is configured is configured to threadedly engage with the second cap to secure the weighted units in the second receiving space.

A modular exercise bar and weight system is provided. The system includes a first bar, a second bar, and a third bar. Each bar includes an attachment mechanism on each end such that the bars may be connected end-to-end in a variety of different configurations. The system also includes one or more weight members configured with compatible attachment mechanisms such that the weight members may be attached to the ends of the modular bars to increase the weight of the bars. The weight members also be attached to one another so that multiple weight members may be attached to any end of any bar combination.

Provided is a weight-adjustable dumbbell, including a grip bar assembly, a dumbbell seat, a plurality of dumbbell discs placed on the dumbbell seat; the grip bar assembly includes a plurality of hanging discs arranged adjacent to each other and are rotated synchronously, and the hanging discs are rotated relative to the dumbbell discs to setting positions to engage with or disengage from the dumbbell discs. The grip bar assembly also includes at least one stopping mechanism, each stopping mechanism includes at least one locking component, and the dumbbell seat is provided with a limiting hole for the locking component to be engaged with. When the hanging discs are rotated to a setting position, the locking component is disengaged from the limiting hole to maintain an unlocked state. When the hanging discs are rotated between two setting positions, the locking component is inserted into the limiting hole to maintain a locked state.
