The present disclosure generally pertains to barbell and dumbbell support systems that allow for a user to perform exercises without requiring movement of the body of the user from the proximity of weight support assemblies when weights are in use. Weight support systems include extendable arm assemblies for the holding and positioning of barbells or dumbbells in a location conducive to performing exercises. Extendable arm assemblies automatically retract when a user removes the barbell or dumbbells from the assemblies, allowing the user to perform the intended exercise without moving away from the system. The retracted position of the extendable arm assemblies allows the user to replace the weights without the assistance of others at the conclusion of the exercise.

The present disclosure is directed to foldable roping dummy assemblies and systems. In a first illustrative embodiment, a central support portion may have right and left leg assemblies and an upper body chamber generally formed as tube. A body cylinder slidable in the upper body chamber may be connected to a head assembly via a linkage at a front end. In a folded position, the head assembly resides between the leg assemblies. As the head assembly is lifted into position, the body cylinder slides rearward and the linkage rotates the head assembly into position at the front of the upper body chamber. In a second illustrative embodiment, the central support portion may be formed as a set of stairs which includes a central cavity open on at least one side, such that in a folded position, the head assembly resides in the central cavity.

A weightlifting assembly includes a wall mount bracket configured for mounting to a wall surface and a weightlifting rack assembly connected to the wall mount bracket. The weightlifting rack assembly may have various configurations, including a foldable weight rack assembly, a pull-up bar, a fixed weightlifting rack, a wall-mount weightlifting rack, or various other configurations. The wall mount bracket may be elongated along a lateral width thereof and may have a first mounting region and a second mounting region spaced from each other along the lateral width of the wall mount bracket. The wall mount bracket may also include a central panel that is spaced from the wall surface to provide clearance for fasteners for connection to the weightlifting rack assembly, and in some embodiments, the weightlifting rack assembly may be connected to multiple wall mount panels.

A sensing base for an adjustable free weight may include a cradle, and a sensing assembly, which includes a plurality of sensors and mechanical components (e.g., pivoting levers), each associated with a respective plate well that accommodates a weight plate of the adjustable free weight such that each mechanical component actuates the state of a respective sensor upon placement or removal of the weight in a plate well. Sensor signals reflecting the states of the sensors are communicated, via a circuit, a processor to determine the weight selection of the adjustable free weight when removed from the base. The sensing assembly may be implemented using individual sensors of a variety of different types such as hall effect sensors, optical interrupt sensors, IR optical sensors, and the like. The base may be configured to automatically communicate the determined weight to an external computing device to facilitate activity tracking and/or fitness coaching.

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.

An apparatus comprises a shaft; an openable and closable canopy; and a plurality of upwardly extending holding chambers on an underside of the canopy. The apparatus is thought to be particularly useful as a golf chipping game, with golf balls being chipped into the holding chambers as target practice.

A rooftop mount device for connecting to a roof of a portable gym and for attaching exercise equipment is described. The portable gym is a portable container, such as a shipping container, having a top surface, or roof, to which the rooftop mount is attachable. The rooftop mount device includes connection members. The rooftop mount can also include one or more horizontal stabilization members and equipment attachment elements. The connection members are attached to a roof of the container. Exercise equipment is attached to the parts of the rooftop mount device. The rooftop mount provides proper height and stability for the bars, racks, stands, cages, rigs and riggings, and other exercise equipment that are attached to the container's roof so that the equipment does not move during use by an exerciser. Systems and kits are also described, which include a rooftop mount device, various exercise equipment, and a portable container.

An adjustable dumbbell device includes a dumbbell having two weight ring supported on a receptacle, a handle having two end housings to be coupled to the weight rings, two weight members engageable into the housing, two spring biased catches engaged in the weight member, two arms coupled to the spring biased catches for moving the spring biased catches into and out of the weight members, a carrier slidably engaged in the receptacle and having a pole and a stud of different height for engaging with the arms and for actuating the arms to disengage the spring biased catches from the weight members, and an actuator moves the carrier relative to the receptacle to control an engagement of the pole and the stud with the arms.

The present invention discloses a weight adjustable dumbbell, which includes a dumbbell assembly, a dumbbell seat and a plurality of dumbbell pieces placed on two sides of the dumbbell seat, wherein the dumbbell assembly includes a handle tube, tailstock assemblies provided on two sides of the handle tube, a fixed shaft provided throughout inside the handle tube and the tailstock assembly and two telescopic tubes symmetrically sleeved outside the fixed shaft, wherein the handle tube is rotatably connected between the two tailstock assemblies, the handle tube is a hollow tube pieces, with an inner wall thereof being provided with two guide grooves with opposite screw directions, one end of the telescopic tube close to the center of the handle tube is provided with a guide block, and the other end thereof is symmetrically provided with an anti-rotation block, the tailstock assembly includes a tailstock body.

A monitoring system is disclosed for the regulation of the weight of a dumbbell, employable by a user for the execution of a gymnastic exercise, comprising a supporting frame, a dumbbell, placed on said supporting frame, equipped with a handle, having an axial development along an axis (R), capable of rotating around said axis (R), clockwise and counterclockwise, and equipped with a first end and a second end, a first plurality of weights, placed on said supporting frame, in which each weight is individually coupable to said first end by a first selection member, when said handle rotates one way, and detachable from said first end, when said handle rotates the opposite way, a second plurality of weights, placed on said supporting frame, in which each weight is individually coupable to said second end by a second selection member, when said handle rotates one way, and detachable from said second end, when said handle rotates the opposite way, said system comprising at least one detection device capable of detecting at least one physical phenomenon caused by the rotation of said handle to couple or detach one or more weights of said first and second plurality of weights to and from said handle.
