The present disclosure provides a rotary dumbbell. The rotary dumbbell includes a handle part, a base part, weight parts arranged at two ends of the handle part respectively, and a transmission self-locking mechanism and a driven mechanism which are arranged at the two ends of the handle part respectively and abut against the weight parts respectively. The transmission self-locking mechanism includes a transmission assembly and a self-locking ring; the transmission assembly includes a planetary gear transmission mechanism, a first output screw, a long nut and a first screw spline. The driven mechanism includes a decorative ring, a second handle flange, a second transition flange and a driven assembly. The driven assembly includes a second output screw and a second screw spline; the weight parts are provided with weight plates with a dovetail groove structure; and the base part is provided with an unlocking thimble.

An apparatus includes a cuboid exercise weight and one or more wall mounts. The exercise weight may be utilized in a variety of workouts due to the various locations and angles of the handles. Further, the exercise weight may be attached to the one or more wall mounts allowing for the user to perform exercises from an elevated position.

A dumbbell facilitating weight adjustment is disclosed. The dumbbell includes a dumbbell rod assembly, multiple counterweight disks, and a base for placing the dumbbell rod assembly and the multiple counterweight disks. The dumbbell rod assembly includes a mandrel, fixed disks and gear rotating disks fixed on the left and right sides of the mandrel, positioning rings and multiple coupling flanges. Rotation interference devices for preventing a rotation of the mandrel are provided in the fixed disks. Unlocking devices for unlocking the rotation interference devices are provided on the base. The rotation interference devices include push rods arranged on front sides and rear sides of the positioning rings, pressing rods arranged on upper parts of the push rods and return springs arranged on upper parts of the pressing rods. The unlocking devices include push pillars arranged on the base and cooperating with the push rods.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

An exercise machine component comprises a cable connection base adapted to attach to an end of a cable, a chamber adapted to receive a key through an opening of the chamber, a biasing mechanism within the chamber, and a receiving groove within the chamber wherein the biasing mechanism biases the key against the receiving groove so that the key is securely fixed within the chamber.

The hinged dumbbell holder for a weight bench is configured for use with one or more dumbbells. The hinged dumbbell holder for a weight bench is configured for use with a stanchion of a weight bench. The hinged dumbbell holder for a weight bench attaches to the stanchion of the weight bench. The hinged dumbbell holder for a weight bench forms a supporting structure that elevates the one or more dumbbells above a supporting surface. The hinged dumbbell holder for a weight bench incorporates a mounting bracket, a dumbbell support structure, a hinge, and a rotation assist structure. The stanchion, the dumbbell support structure, the hinge, and the rotation assist structure attach to the mounting bracket. The dumbbell support structure physically receives and elevates the one or more dumbbells. The hinge and the rotation assist structure rotate the dumbbell support structure into a storage position.

A novel outdoor workout station includes a platform, an exercise structure, and a canopy assembly. The exercise structure is disposed on and fixed to the platform, and the canopy assembly is disposed over both the exercise structure and the platform. The arrangement of support beams of the platform corresponds to a footprint of the exercise structure. In a particular embodiment, the platform includes adjustable legs that facilitate the leveling of the platform. In another particular embodiment, the canopy assembly is mounted directly to the platform.

A cradle for supporting an adjustable free weight assembly that includes first and second weight plate sets. End walls and side walls of the cradle define a cavity sized to receive the free weight assembly. The end walls engage plate portions and locking element portions of outermost weight plates of the free weight assembly when received in the cradle. Inboard surfaces of the side walls engage portions of weight plates in at least the first weight plate set to substantially inhibit the first weight plate set from moving vertically or laterally between the side walls. The configuration of the inboard surfaces of the side walls aligns the weight plates in the first weight plate set both vertically and horizontally so that central openings in the weight plates for receiving a selector shaft are substantially concentric.

A treadmill includes a platform where the platform includes a first side panel and a second side panel spaced apart at a distance from the first side panel, and a gap defined between the first side panel and the second side panel. The treadmill also includes a running deck contained within the platform and exposed within the gap, a first pulley connected to the running deck, a second pulley connected to the running deck opposite the first pulley, a tread belt surrounding the first pulley and the second pulley. A motor is in mechanical communication with at least one of the first pulley or the second pulley. A cover is located over the motor. A scale mechanism is incorporated into the cover over the motor.
