A folding exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The folding exercise rack generally includes a plurality of extension members pivotably connected to wall-connected mounting brackets. Upright support members connected to the extension members support a barbell and exercise bar. The exercise rack is pivotable from an extended exercise position into a plurality of selectable compact storage positions substantially parallel with and closely adjacent to the wall. The mounting brackets include a plurality of selectable connection points to determine how much space is present between the wall and exercise rack in the storage positions. One connection point allows a retractable exercise bench to be stored in the space between the wall and exercise rack. Mechanisms are provided for locking the exercise rack in a plurality of selected positions.

A power rack attachment system and associated method are provided. An example of the power rack attachment system includes a hand crank and a gearbox coupled to the hand crank, the gearbox comprising a plurality of gears connected to a lead screw, wherein the plurality of gears causes the lead screw to rotate in a vertical translation based on a radial motion of the plurality of gears. The power rack attachment system includes a guide housing connected to the gearbox, the guide housing comprising the lead screw, a vertically translating nut, and a guide rod, wherein the lead screw is connected to the vertically translating nut, such that rotation of said lead screw leads to vertical translation of said vertically translating nut. The power rack attachment includes a j-cup connected to the vertically translating nut, wherein the vertical translation of the vertically translating nut causes vertical translation of said j-cup.

A method and system for measuring exercise data using a plurality of wireless sensors is disclosed. The plurality of wireless sensors are attached onto or into a plurality of pieces of strength training equipment, wherein each individual wireless sensor from the plurality of wireless sensors is attached to and associated with an individual piece of strength training equipment of the plurality of pieces of strength training equipment. An individual piece of strength training equipment of the plurality of pieces of strength training equipment is selected and the wireless sensor is registered with selected piece of strength training equipment with a computing device. Strength training equipment details may be identified through the computing device.

An article of manufacture providing an exercise device for work-out with a stroller according to the present invention includes the stroller having a frame having a front portion and a rear portion, a front wheel assembly coupled to the front portion of the frame, a pair of rear wheels coupled to the rear portion of the frame and a handle coupled to the rear portion of the frame above the pair of rear wheels and a plurality of barbells coupled across the stroller for supporting removable weights on both ends of the barbells. A first barbell coupled across the rear portion of the frame between the pair of rear wheels and the handle. A second barbell coupled across front wheel assembly. A third barbell coupled across the handle.

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

The present disclosure relates to a grip apparatus for exercise equipment, the grip apparatus comprising: a first annular member having a first annular sidewall and a first flange extending radially inwardly from the first annular sidewall; a second annular member having a second annular sidewall and a second flange extending radially .[.inwardly.]. .Iadd.outwardly .Iaddend.from the second annular sidewall, a diameter of the second annular sidewall being less than a diameter of the first annular sidewall, the second annular member being positioned within the first annular member whereby the first annular sidewall, the second annular sidewall, the first flange and the second flange define together an annular chamber; a handle member connected to the second annular sidewall; and a bearing in the annular chamber, the first annular sidewall frictionally engaging a first race of the bearing and the second annular sidewall frictionally engaging a second race of the bearing.

An adjustable weight lifting device (21) includes a tube (31), a pin (33) movably disposed inside the tube (31), the pin (33) comprising an external thread (35), and one or more driving knobs (51) extending radially inward relative to an inner wall of the tube (31) and engaging with the external thread. The external thread comprises at least one portion having a first helix angle and at least one portion having a second helix angle, the second helix angle being smaller than the first helix angle.

A system for adding weight and clamping a bar, as non-exclusive example, a barbell collar, includes a weighted collar attachable to a clamp. The clamp may include configurations that mate with the weighted collar, for selectively retaining and removing the weighted collar from mate with the clamp.

A modular, portable, multi-purpose workout system is easily transported and reconfigured for different standing and seated workouts. The system at least includes a platform, a seat with a backrest, and a pair of variable resistance modules, each including an outwardly extending cable that is pulled by a user. For standing workouts, at least one of the variable resistance modules is coupled to a platform, and a user pulls up on the cable while standing on the platform. For seated exercises, at least one of the variable resistance modules is coupled to the backrest of the seat, and the cable is pulled outwardly and toward a seated user. The variable resistance modules are coupled to the platform or the backrest of the seat using elongated rigid members. The variable resistance cables may be pulled with separate handles or pulled simultaneously with a barbell component forming part of the system.

A device designed to hang free weight dumbbells from the end of an elongated cylindrical lifting bar. The device is comprised of a cylindrical hollow head which is capable of sliding and hanging on to a barbell, while the openly hollow C-shaped support inferior to the neck of the device is free to safely support a free weight dumbbell during resistance training.
