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.

An exercise assist apparatus may include a frame and a cam assembly pivotally connected to the frame. A cable having one end fixedly secured to the frame may extend over a traveling pulley operably connected to the cam assembly and about a fixed pulley connected to the frame. One or more flexible progressive resistance bands may provide substantially linear assistance/resistance throughout an exercise.

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.

A strength training machine includes a first motor oriented at a first angle relative to a chassis. It further includes a second motor oriented at a second angle relative to the chassis. The first and second angles skew the motors with respect to each other.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

An exercise device system comprising a tower; a support structure inclinable at different angles relative to the tower; a movable user support platform movably associated with the support structure for movement relative to the support structure; a pulley system associated with the movable user support platform; a cable extending through the pulley system and including opposite ends; exercise device handles coupled to the opposite ends of the cable, whereby movement of the handles causes movement of the movable user support platform relative to the support structure.

A collapsible exercise bar includes two elongate sections; attachment means for connecting the two elongate sections together and for permitting the two elongate sections to move relative to each other between a position in which the two elongate sections are aligned for use of the bar, and a folded position in which the two elongate sections are generally parallel to each other. A retainer member is slidable relative to the two elongate sections and includes attachment means for engaging cooperating attachment means on one of the two elongate sections to immobilize the retainer member in a position overlying contiguous edges of the two elongate sections when the two elongate sections are aligned for use of the bar. A connector is provided on the exercise bar and is configured to be connected to a resistance device.

An exercise apparatus including a base, a support extending from the base, a lever, at least one seat arm and a seat is disclosed. The lever, which is pivotally connected to the support about a first horizontal pivot axis, has first and second portions extending on, respectively, first and second sides of the first horizontal pivot axis. The at least one seat arm upper portion and lower portions connected to, respectively, the first portion and the seat. The seat is pivotally connected to the first portion about a second horizontal pivot axis, which is parallel to the first horizontal pivot axis, via the at least one seat arm. The lever selectively pivots about the first horizontal pivot axis between first and second positions, the seat being higher in the first position than in the second position, and the lever being biased toward the first position.

A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.

A method for controlling exercise load variations in a strength exercise machine, includes, at a current time instant t.sub.i, detecting an exercise position within a set range of motion of a user, and checking if a previously set trigger condition of an exercise load variation includes the detected exercise position of the user within the set range of motion. If a previously set trigger condition of an exercise load variation includes the detected exercise position of the user within a respective range of motion, the method includes setting a trigger condition of an exercise load variation as the current trigger condition of exercise load variation having a first speed threshold for execution of motion by the user, and reducing an exercise load based on a comparison of speed for execution of motion by the user and the first speed threshold.
