A variable-resistance exercise machine with wireless communication for smart device control and interactive software applications, comprising a wireless network interface that receives input from a user device and provides output to a user device; a plurality of moving surfaces that each provide an independent degree of resistance to movement based on received input and that detect movement and provide output to a user device based on the movement; and a plurality of rigid rails that provide a rigid support for a human user to grasp, and that provide attachment points for a user to affix a variety of devices.

A limiting structure for a body-training device includes a base, a positioning shaft, and a controlling member. The base comprises a slidable sleeve and the base is fixed on the foundation. The slidable sleeve has a shaft hole. The pivot holder of the body-training device has a positioning portion aiming at the shaft hole. The positioning shaft passes through the shaft hole. When a frame of the body-training device is standing, the positioning shaft can be slid to connect to the positioning portion so as to limit the pivot holder not to swing laterally. The controlling member is assembled on the frame and combined with the positioning shaft to control the positioning shaft to be slid to connect to the positioning portion or to be slid to detach from the positioning portion.

An exercise apparatus with oscillating tilt system includes a main frame for supporting all the components of the apparatus, a tiltable upstanding support is tilted oscillating, a mechanism which enabling a user of the apparatus to move hands and feet up and down harmoniously, and another mechanism to change an orientation of the user in relation to the vertical line oscillating during the exercise, and consequently changing the direction of the forces affecting different muscles of the user of the apparatus.

A system for a virtual and mixed-reality enhanced exercise machine that allows a user to exercise while interacting with a virtual reality or mixed reality environment using whole body movements and positioning, and receiving haptic feedback associated with the user's interaction with the virtual reality or mixed reality environment.

An exercise device has a main rod, a connecting unit, and a sub rod. The connecting unit has a first plate and a second plate, and the first plate and the second plate are both provided with an axial hole and a rotating axis. The first plate has an arced slot, and the second plate has a closing aperture, a first positioning aperture, a second positioning aperture and a third positioning aperture. The sub rod has a through aperture and a connecting aperture at an end, and the through aperture is inserted with the rotating axis. Another end of the sub rod has a front stand and a control member disposed in the connecting aperture of the sub rod. One end of the control member passes through the arced slot of the first plate to form a pull knob, another end of the control member has an inserting pin.

A composite motion exercise machine includes a control panel which provides a plurality of movement modes and allows a user to issue a command to change the configuration of linkage units of the exercise machine to have the machine perform a movement mode without manual adjustment, so that the pedal of each linkage unit can be moved along a closed trajectory. The control panel also allows the user to finely adjust the trajectory and the resistance associated therewith. The trajectory performed by each pedal of the exercise machine is ergonomic so that the user can be protected from exercise injury.

An exercise apparatus includes a frame adapted to be rested on a floor surface, a crank mechanism that has two cranks mounted on the frame, two swing members pivotally mounted on the frame, two connecting assemblies, and a guiding device. Each of the two connecting assemblies has a plurality of connecting rods connecting the respective crank and the respective swing member. The two connecting assemblies define two pedal portions for supporting a user's feet, and up-and-down movement of the pedal portions causes rotation of the two cranks along a circular path. The guiding device is configured to connect the two swing members for guiding swing movement of the two swing members within a predetermined swing range. The predetermined swing range is adjustable so as to provide various exercise paths.

Systems and methods for identifying a condition of a user. An electromechanical machine is configured to be manipulated by the user for. An interface is communicably coupled to the electromechanical machine. A processing device and a memory are communicatively coupled to the processing device, and the memory includes computer readable instructions that, when executed by the processing device, cause the processing device to receive, from one or more sensors, one or more sensor inputs representative of one or more of characteristics of an anatomical structure of the user, calculate an infection probability based on the one or more characteristics of the anatomical structure, and output, to the interface, a representation of the infection probability.
