A stretching apparatus includes a body frame including a pair of support frames extending in parallel in upward and downward directions at a certain interval and a connection frame connecting the pair of support frames, an upward and downward adjustment module that is movable in upward and downward directions to adjust a level thereof in the upward and downward directions between the pair of support frames and rotatable within a certain angle range based on the upward and downward directions, and a level support fixed to an inner side of each of the pair of support frames and configured to allow upward and downward movements of the upward and downward adjustment module or limit a downward movement of the upward and downward adjustment module depending on a rotation angle of the upward and downward adjustment module.

An exercise posture analyzing device, according to an embodiment, for analyzing an exercise posture of a user of exercise equipment, includes a photographing unit configured to obtain an exercise image of the user by photographing the user who is exercising by using the exercise equipment, an equipment detector configured to detect exercise equipment-related information relating to at least one of a movement and a length of the exercise equipment, and an analyzer configured to calculate a rotation angle of a body part of the user based on the exercise image and identify the exercise posture of the user based on the calculated rotation angle of the body part of the user.

Provided is a weight exercise device. The weight exercise device includes: an exercise body in which a motion is generated according to a weight exercise of a user; a sensor configured to detect the motion of the exercise body; a display configured to output a user interface screen; and a processor configured to control the display to display, on the user interface screen, a first indicator indicating an exercise state of the user corresponding to the detected motion and a second indicator indicating an exercise guide that is recommended when exercising using the exercise body, wherein the processor is further configured to control the display such that a position of the second indicator is adaptively changed based on the exercise state of the user.

Provided are an exercise management method and server thereof. The exercise management method includes providing a notification that an exercise mode is set with respect to a first exercise machine from among a plurality of exercise machines and setting a second exercise machine arranged within a predetermined distance from the first exercise machine from among the plurality of exercise machines in a lock mode.

Provided is a weight exercise apparatus. The weight exercise apparatus includes an exercise main body in which movement is generated according to a user's weight exercise, a sensor module configured to detect movement of the exercise main body, and a processor configured to control a user interface (UI) unit to display a UI element indicating an exercise state of a user corresponding to the detected movement on a UI screen wherein the sensor module includes a first laser sensor configured to irradiate a first laser beam toward the weight plate or a component moving together with the weight plate to detect a moving distance of the weight plate when the weight plate moves and a second laser sensor configured to irradiate a second laser beam toward a component that does not move in spite of movement of the weight plate when the weight plate moves.

An exercise equipment device includes an exercise device body including a load applying unit configured to add, reduce, or maintain a load according to a set exercise level, a user manipulation unit moving according to a movement of a user, and a load transmitting unit configured to transmit the load applied by the load applying unit to the user manipulation unit, a sensor configured to detect movement information of the user manipulation unit, a user input unit configured to input user information, and a processor configured to determine a first user motion range based on a detection result of the sensor and the user information, wherein the processor is further configured to determine the first user motion range based on the user information, an upper limit movement range and a lower limit movement range.

Provided is a weight exercise apparatus. The weight exercise apparatus includes an exercise main body in which movement is generated according to a user's weight exercise, a sensor module configured to detect movement of the exercise main body, and a processor configured to control a user interface (UI) unit to display a UI element indicating an exercise state of a user corresponding to the detected movement on a UI screen wherein the sensor module includes a first laser sensor configured to irradiate a first laser beam toward the weight plate or a component moving together with the weight plate to detect a moving distance of the weight plate when the weight plate moves and a second laser sensor configured to irradiate a second laser beam toward a component that does not move in spite of movement of the weight plate when the weight plate moves.

As a preferred embodiment of the present disclosure, an AI exercise guide device includes a muscle strength estimation unit for estimating an estimated muscle strength value of a user's specific muscle strength based on user data, a detection unit for detecting a percentile value to which the estimated muscle strength value belongs among preset adult muscle strength percentile values, and a PMW estimation unit for estimating a PMW of exercise equipment the user intends to use based on the detected percentile value.

An artificial intelligence (AI) workout guide device includes a storage storing one or more muscles activated when fitness equipment is used, a contribution of each of the one or more muscles, and an workout trajectory guide generated when accurately using the fitness equipment in a correct posture, a sensor configured to detect an workout trajectory corresponding to movement of a user moving the fitness equipment, an AI processor configured to determine whether a deviation between the workout trajectory detected by the sensor when the fitness equipment is moved in at least one direction matches the workout trajectory guide, and a workout guider configured to, when the deviation between the workout trajectory and the workout trajectory guide exceeds a preset value, guide to adjust an workout load of the fitness equipment or an workout posture.
