A physical exercise equipment set may include an elongated connecting bar having two ends and each end having a threaded engaging hole; a plurality of weighted portions; and two or more dumbbells. Each dumbbell has a handle having an elongated threaded portion at each of two opposite ends, a pair of weighted units located at two opposite ends of the handle, and a securing unit to secure each weighted unit in a predetermined position on the handle. For each of the two dumbbells, one of the weighted portions is taken out from one side of the handle, and the threaded portion is inserted into and threadedly engaged with each of the two threaded engaging holes of the connecting bar to form a barbell.

A multipurpose exercise device is provided. The device includes features which allow the device to exhibit self-stabilizing features. The device includes a weighted body characterized by at least three substantially-loop-shaped handles which have dimensions and arrangements that are effective to cooperatively urge the device into one of several predetermined self-stabilizing rest positions. The rest positions are characterized by engagement portions of two of the provided handles resting against a support surface, while an elongated device bore extending along a center axis of the device is maintained in a substantially-horizontal orientation. The device may be stored safely in a variety of arrangements, including on a rack typically used for dumbbell storage.

Bootstrap converts any hiking bottle into a safe and long-lasting weightlifting device. It consists of two main components: 1″-1.5″ plushed strap with low elasticity and high durability, 0.4″ or thicker silicon bumper for bottle bottom.

Several embodiments have additional components used as connection items. VELCRO® brand VELSTRETCH® tape is a perfect material for the heavy bottle strap. It is used in industrial applications to withstand multiple expansions/contractions and to minimize shear stress on hands. Thick silicon bottom bumper absorbs stress coming from two bottles collision that is common for such weight lifting exercise. Overall design protects hikers head, hands, and body from injuries. Several embodiments varying aesthetically and in cost are presented. Basic math provided in the background section explains current solutions' failures. The same math lays the path to the bootstrap.

A weight lifting system includes a first weight, having a first cavity extending from a bottom surface of the first weight to an interior of the first weight; the first cavity is configured to receive a first hand of a user; and the first cavity positions the first hand in an open position, thereby forcing the user to press the first weight without forming a grip.

A training device having a beam (1), weight receptacles (2), and two handle attachments (3), which extend in a transverse direction in relation to the beam (1) and each comprise a handle part (4), is described. To design a training device of the type described at the outset in such a way that the risk of injury is avoided without an increase of the construction expenditure accompanying this, it is proposed that weight receptacles (2), on the side of each of which facing away from the beam (1) a handle (8) is rotatably mounted around the longitudinal axis of the handle attachments (3), are provided on the side of the handle attachments (3) opposite to the beam (1).

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.

As disclosed herein a grip apparatus for attachment to a weight plate is provided herein for enabling the weight plate to be used as a grip plate like those having handles integrally formed therein. The grip apparatus may include a grip handle, at least one adapter element, and at least one coupler. The grip handle my circumscribe at least a portion of the weight plate. The at least one adapter element may be coupled to the grip handle and may further be configured to adjustably extend therefrom. The at least one coupler may be coupled to each of the at least one adapter element proximate a distal end thereof and may further be configured to selectively engage the weight plate. The at least one adapter element may comprise two adapter elements positioned so as to enable the couplers to engage opposite sides of the weight plate.

A portable weight-based exercise system is disclosed that is capable of providing a user with a variety of weight-based exercise options. The exercise system includes a carrying case having a housing, containing dumbbells and a collection of weight disks for performing a variety of exercises, and a removable handle assembly for carrying or dragging the housing along the ground. First and second end bars and a center bar of the handle assembly are reconfigurable from a first configuration wherein they are disposed in a U-shaped arrangement to form the handle assembly to a second configuration wherein the first and second end bars are coaxial with the center bar to form a longer straight bar, which can then be combined with the dumbbells and collection of weight disks to form an assembled long weight bar. The housing may additionally include accessories such as a jump rope and an exercise band.

A dumbbell and barbell supporting system includes two tables rotatably attached to a base and rotatable relative to the base to two working positions where the tables are inclined relative to each other or are in line with each other, and two dumbbells disposed on the tables, the dumbbells each include two or more weight members or two weight elements, and a handlebar engageable with the weight members and the weight elements for detachably coupling the weight members and the weight elements to the handlebar, the tables are rotatable to be in lined with each other, and a longitudinal bar engageable with the weight members and the weight elements for forming a barbell exerciser device.

This utility model relates to the field of dumbbells and, in particular, to an adjustable dumbbell comprising knobs, bridge-shaped blocks, weight plates, a lift assembly, side plates, an anti-slip assembly and sleeves. The number of the weight plates is two, and they are fixedly attached to the opposing ends of the lift assembly. The bridge-shaped blocks and the weight plates are fixedly disposed between the lift assembly and the knobs. Separation of sockets from inserting plates concurs with extraction of a securing bar from a second through hole and from a first through hole. The handle may be then pulled to a desired position by virtue of the movement of locking blocks in respective locking grooves.
