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.

A barbell includes a rotational body including a bar, a sleeve assembly having a sleeve with a bore, where a portion of the bar is received through the axial bore, a proximal bushing received in the bore and having a passage receiving the bar, a distal bushing received in the bore and having a cavity receiving a portion of the body. The proximal bushing has a first outer surface engaging the sleeve and a first inner surface engaging the bar within the passage. The distal bushing has a second outer surface engaging the sleeve and a second inner surface engaging the portion of the body within the cavity. The proximal bushing and the distal bushing permit the sleeve assembly to rotate around the body, and at least one of the first inner and outer surfaces and at least one of the second inner and outer surfaces are polymer surfaces.

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.

A bracket assembly for an exercise apparatus and the like is disclosed. The bracket assembly includes a plate member having a U-shaped chamber. The plate member includes a gusset extending from an outer side of the plate member. The plate member further includes a pin extending from the outer side of the plate member. The gusset receives a rack of an exercise apparatus. The pin inserts in one of a plurality of rack openings and connects the bracket assembly to the rack. A user places a barbell in the plate member through the U-shaped chamber. The U-shaped chamber allows the user to have a safe and controlled upward and downward motion for performing exercises with the barbell while in a seated or standing position. The U-shaped chamber acts as a holder for the barbell and prevents the user from tipping over or losing balance holding the barbell in the chamber.

An adjustable weight exercise system is provided. A permanent weight assembly and a plurality of interlocking weights are provided. A base comprises an interlocking weight carrier, wherein the interlocking weights are supported on the interlocking weight carrier and an interlocking weight selector, wherein the interlocking weight selector is adapted to cause interlocking weights to be set to be locked to the permanent weight assembly while the permanent weight assembly is not on the base, wherein placement of the permanent weight assembly on the base causes interlocking weights that are set to be locked to the permanent weight assembly to be locked to the permanent weight assembly, and wherein placement of the permanent weight assembly on the base does not cause interlocking weights that are not set to be locked to the permanent weight assembly to be locked to the permanent weight assembly.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

An adjustable kettlebell device comprising a solid right circular frustum as a base, a post, a sleeve, one or more weight plates, one or more quick release clamps, and a removable handle. The post has an outer diameter compatible with standard weights, and a sleeve that slides over the post has an outer diameter compatible with Olympic weights. The handle is configured to facilitate an addition/removal of the weight plates, and may be swapped with different sized handles for use with different sized hands.

An exercise bar assembly includes a pair of rotating grip assemblies, each including a generally planar frame and a hand grip mounted within the frame for rotation within in the plane of the frame. The rotating grip assemblies are attachable to opposite ends of a center bar assembly along the longitudinal axis of the bar assembly. A plate bar assembly is attachable to each of the rotating grip assemblies opposite the center rod, with the plate bar assembly aligned with the longitudinal axis to form a weight lifting bar. A user-selectable elastic band is engageable between the pair of rotating grip assemblies along the longitudinal axis so that the elastic band resists rotation of each hand grip in each of the rotating grip assemblies. The rotating grip assemblies of the exercise bar assembly allow for the full range of motion of the bicep, and the elastic band creates a resistance exercise through the bicep's full range of motion.

A system for measuring actual weight lifted by a user when a spotting force is applied and calculating a spotting force. The system is comprised of a display device and sensors having strain gauges attached to a weight lifting bar. The system will determine and display the actual weight lifted by a user with or without a spotting force, and a spotting force applied.

A clamping device for securely engaging one or more objects through an application of pressure. The clamping device includes a primary member having opposed interior and exterior surfaces. The primary member has a generally cylindrical shape such that the interior surface defines a generally circular space about a center point of the primary member. The clamping device can receive an elongated member through the generally circular space circumscribed by the primary member. The primary member is adapted for clamping and releasing such that the clamping device may releasably engage the elongated member. The elongated member is securely retained by the clamping device through the application of pressure.
