Disclosed is a workout backpack that is capable of enabling a plurality of unique exercises for weight training, resistance training, and complete cardio conditioning. Suitably, the disclosed workout backpack includes built-in weight compartments, hookups for resistance bands, or rucking.

A fitness tool is described. The tool includes a grip component and a handle component. The handle component includes sensors and the grip component includes an electronics unit. The electronics unit includes a fitness application. The fitness application receives a signal from a button located on the grip component to signal that the user is performing an exercise. The fitness application also receives a measurement of force applied to the handle component from the sensors. The fitness application processes the signal and the measurement of force and then transmits the signal, the measurement of force, and other exercise metrics to a computing device. The user interacts with another application on the computing device to view, track, and modify these exercise metrics.

A clamp for exercise equipment. The clamp includes a body. The body is configured to receive a portion of a piece of exercise equipment. The body includes a first portion, a second portion and a hinge connecting the first portion and the second portion. The clamp also includes a neck. The neck is cylindrical in shape. The neck includes a first portion attached to the first portion of the body and a second portion attached to the second portion of the body. The clamp further includes a securing mechanism, the securing mechanism configured to secure the first portion of the neck to the second portion of the neck. The neck is configured to secure to an external handle when secured by the securing mechanism.

In one aspect, the invention features a barbell including a first end portion, a second end portion, and a middle portion, where the middle portion is couplable to the first end portion and the second end portion. The middle portion includes a male coupling extending from a first end of the middle portion, the male coupling providing a first coupling mechanism that engages with a corresponding female coupling of the first end portion, and a female coupling providing a second coupling mechanism that engages with a corresponding male coupling of the second end portion.

A weight member and the use in barbell and dumbbell devices are provided, wherein the weight member has a first side and a second side opposite to each other, and a split groove through the first side and the second side. A first mortise and a first tenon are arranged on the first side, and a second mortise and a second tenon are arranged on the second side. The first mortise and the second tenon are arranged in opposite direction correspondingly, and the first mortise and the second tenon are opposite to each other and arranged correspondingly. When the weight members are assembled together, the first mortise and the first tenon of one weight member is sliding interlocked with the second tenon and the second mortise of another weight member respectively.

A kettle bell including a weighted mass and a handle or grasping ring extending from an upper portion of the mass, and at least one opening or receiver formed through at least a portion of the mass and/or handle. In example embodiments, the at least one opening or receiver is provided for accommodating interengagement with the end male receivers of a barbell or other exercise device. In other example embodiments, one or more portions of the kettle bell is at least partially deformable or flexible.

A handheld weight exercise system includes a plurality of plates of varying weights. Each plate includes at least one connector assembly for detachably connecting the plate to another adjacent plate. Each plate includes a handhold aperture, which is alignable with a handhold aperture of an adjacent plate when the two are connected to one another, for grasping and moving the one or more plates.

The present invention is an exercise apparatus which has a designated weight, in terms of pounds and/or kilograms. It includes a lower weight element attached to an upper handle, similar to a Kettle Bell. Unlike a Kettle Bell, however, its interior core comprises a concrete material, through which passes a cylindrically tubular transverse channel. The transverse channel is adapted to accommodate the cylindrical plate bar of a barbell and/or a dumbbell. Preferably, the transverse channel has a PVC lining, in the form of a congruous PVC pipe, which is operative to facilitate sliding of the plate bar through the transverse channel. The PVC-lined transverse channel allows the present invention to be used like a conventional weight plate, as well as like a Kettle Bell.

A barre exercise device providing balance support for a user during exercise may include a horizontal barre exercise bar and a pair of brackets. The horizontal barre exercise bar is elevated above a floor surface by supporting structure in contact with the floor surface. The pair of brackets is attached to the supporting structure. Each bracket of the pair of brackets is adapted to support one or more hand weights therein. The device is lightweight yet structurally configured so as to support a user's entire weight thereon.

The disclosure relates to a dumbbell, which includes a first grip rod and a counterweight assembly connected to both ends of the first grip rod, and the counterweight assembly is connected to the first grip rod through a thread structure. As the counterweight assembly of the dumbbell is connected to the first grip rod through the thread structure, different counterweights can be combined and shared to adjust the weight, thus involving a simple and flexible assembly, and the thread structure obtain a firmly connection, so that the counterweights are not easy to loosen or shake, so as to guarantee a high usage safety.
