A handlebar device and an exercise bike are provided. The handlebar device comprises a handle assembly, an electric control clutch part, a base, a return part, and a return detection element, wherein the handle assembly comprises a handle, a pedestal and a rotating shaft, and the handle is fixedly connected to the pedestal, the rotating shaft has one end connected to the pedestal and the other end rotatably connected to the base, the electric control clutch part is connected between the rotating shaft and the base, so that the rotating shaft is fixed or rotatable relative to the base; the return part is connected between the pedestal and the base to make the base return to an initial position; and the return detection element is used to detect that the rotating shaft reaches the to-be-returned position and transmit it to the electric control clutch part.

A method that includes receiving treatment data associated with a user capable of using a treatment device to perform a treatment plan. The method also includes receiving user related data (URD) associated with the use and receiving alignment data associated with the user while the user engages in at least one activity. The method also includes identifying, based on at least the treatment data, the URD, and the alignment data, at least one alignment characteristic associated with the user and modifying at least one aspect of the treatment plan in response to receiving, from a healthcare professional, treatment plan input including at least one modification to the at least one aspect of the treatment plan.

A method for optimizing at least one exercise for a first user. The method includes receiving first user data including attribute data associated with the first user and outcome data associated with the exercise. The method includes generating, based on the first user data, initial target data. The initial target data is associated with at least one of the first user, the exercise apparatus, and the exercise. The method includes receiving measurement data associated with at least one of the first user, the exercise apparatus, and the exercise. The measurement data is associated with one or more sensors. The method includes determining differential data based on one or more differences between the initial target data and the measurement data. The method includes generating, via an artificial intelligence engine and based on the differential data, a machine learning model trained to generate optimized target data.

An exercise chair includes a chair frame, and a base fixed with the chair frame that is adapted to support the exercise chair on a floor surface. The base and chair frame have a plurality of anchors projecting away therefrom. A cushion may cover at least a portion of the frame. Multiple resistance bands each have multiple longitudinal slots therethrough, each adapted for selective fixing with any of the anchor knobs or several attachable exercise devices. In use, with the person seated in the chair and the chair resting on the support surface, one or two of the resistance bands can be fixed with any of the anchor knobs, so that the person can exercise by pushing and/or pulling the at least one resistance band. Different types of attachments are included for exercising varying muscle groups.

A driving and resistance control system for a permanent-magnet synchronous motor is disclosed. A control device includes a processing unit, a motor driving circuit, a resistance controller, and an interlock switch. In a first operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor open-circuiting, and connecting stator windings of the permanent-magnet synchronous motor to the resistance controller, and under this condition, the external rotor of the permanent-magnet synchronous motor is rotated by spinning of a flywheel, so that the permanent-magnet synchronous motor is operating in a generator mode to generate a resisting force to the flywheel by mesas of a resistance generation device. In a second operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor closed-circuiting and cutting off control of the resistance controller, and electrical energy is supplied from the power supply circuit to the permanent-magnet synchronous motor, so as to make the permanent-magnet synchronous motor operating in a motor mode to induce an acceleration on the external rotor.

An interior bike system includes: an interior bike including a rotational angle detection sensor sensing a pedal rotation angular speed; a motion recognition sensor recognizing a head or upper body motion of a player; a heart rate measurement sensor measuring a heart rate of the player; a controller receiving and transferring sensing signals of the rotational angle detection sensor, the motion recognition sensor, and the heart rate measurement sensor to a web server; the web server determining whether performing the task motion given to the player is successful based on the signal of the motion recognition sensor of the controller, and generating a content image to which whether the player succeeds in performing the task motion is reflected and transmitting the generated content image to the content controller; and a display unit displaying an image transmitted from the web server through the controller.

A protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

A cycling device used for exercise and/or rehabilitation includes a shaft for grasping by a user, a foot assembly coupled to the shaft and configured to be supported on a surface, and a pedal assembly coupled between the shaft and the foot assembly. The cycling device is intended to be used by a seated user.

A device and method for estimating a resistance of a wheel of a bicycle is disclosed. The device includes a mounting bracket, a disk, and a resistance adjustment knob. The mounting bracket is coupled to the bicycle. The disk is configured to indicate the resistance. The disk is located within the mounting bracket. The resistance adjustment knob is connected to the disk via a connector. Upon rotation of the knob, the connector rotates the disk for estimating the resistance of the wheel of the bicycle. The determined estimated resistance is visible on the disk.
