An exercise apparatus includes a frame with a pair of vertical guides. A carriage is slidably carried on each of the guides. Each of the carriages has a locking mechanism to lock the carriage at a selected vertical position and a release to disengage the locking mechanism. A horizontal exercise bar is slidably carried on guide rods. First and second cables are coupled to a selectable exercise resistance, each of the cables having an end selectively coupled to either the respective carriage or to a respective bracket at the end of the exercise bar. Secondary brackets on the exercise bar are configured to engage respective ones of the carriage releases and grab the carriage so as to selectively engage and disengage the locking mechanisms upon axial rotation of the exercise bar and raise and lower the carriages with the exercise bar.

A fitness exercise apparatus includes a base member, a support unit disposed on the base member, and a slide bar disposed on the support unit. A seat frame includes a connector connected to and slidable along the slide bar, a guide rail connected to the connector, and a foot post connected to the guide rail opposite to the connector. A swing frame is connected to the guide rail at a position corresponding to the foot post. An elastic cord unit includes a plurality of first and second elastic cords connected to the support unit. A pulling unit includes two first cables connectable with the first elastic cords. An operating unit is connectable with the first cables.

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.

A glute press exercise machine including: a four-bar linkage connected to a stationary frame; a rotatable back support connected to the four-bar linkage; a seat connected to the four-bar linkage; and a foot support connected to the stationary frame. A lower portion of the back support extends below the user's hips to support the users hips during a glute press exercise. This lower portion supports at least 10% of the user's weight. In operation, the seat rotates downwardly away from the user's hips during a glute press exercise and then rotates upwardly again to contact the user's bottom between every repetition of the glute press exercise. The four-bar linkage is pivotally connected to the stationary frame at a location near ground level. The foot support is positioned below 25 cm from the ground and extends forwardly beyond the front of the stationary frame.

An exercise system includes a base structure including a first cross brace including first cross brace mounting plates disposed at each end of the first cross brace. A pair of base guide rail supports is secured to and extended substantially orthogonal from the first cross brace and includes a pair of base guide rail receivers. A pair of base pulley supports is secured to and extended substantially orthogonal from the first cross brace and further includes a pulley-support pulley housing. A pair of pulley-support pulleys is rotatably secured to the pulley-support pulley housing. A second cross brace includes a central portion substantially parallel to the first cross brace. The central portion is secured to the pair of base guide rail supports and the pair of base pulley supports. Two end portions are disposed at an angle to the central portion and terminate at second cross brace mounting plates disposed at each end of the two end portions and two central-portion pulley housings. A central-portion pulley is rotatably secured to each of the two central-portion pulley housings.

A pulley force detection device for a weight-training fitness equipment includes a measured element arranged on a stator portion of a pulley of the fitness equipment, and a detection module arranged on a rotor portion. The detection module includes at least one measuring element corresponding to the measured element to detect a motion stroke, a speed, and a power value during force application to a pulley body. Alternatively, the measured element is arrangeable on the rotor portion of the pulley, while the measuring element is arranged on the stator portion of the pulley. The pulley force detection device is further combinable with a weight measurement device for detecting a weight of the weight block.

A resistance training machine comprises a carriage with a handle coupled to move along a linear guide such as a post. First and second end portions of a flexible element are respectively coupled the carriage. A portion of the flexible element forms a loop defined by a series of guiding elements such as pulleys. The loop is coupled to a resistance element such as a weight. First and second fasteners are respectively provided in the first and second end portions of the flexible element. A user can adjust the carriage to a starting position at their desired height and affix one of the fasteners to an anchor point of the receivers. The user can move the carriage either through causing the loop of the flexible element to be reduced in length and to pull on the resistance element or plates on plate horns to perform resistance training.

A housing for a Time-of-Flight (ToF) range meter includes a wall structure defining a first optical beam path to an emitter of the ToF range meter, and a second optical beam path to a detector of the ToF range meter, and a transmissive optical diffusor configured to cover the beam path to at least one of said emitter and said detector. The housing may be connected to a ToF range meter into a ToF ranging device. Such a ToF ranging device where the ToF ranging device is directed to measure a distance to a reflector member to determine a distance which correlates to the weight of the selectively engaged weights.

An exercise apparatus comprising: a frame; first and second vertical guides coupled to the frame; first and second carriages carried on the respective first and second vertical guides, each of the first and second carriages having an upper carriage portion, a lower carriage portion and a carriage locking mechanism operable to lock and release the lower carriage portion to a selected vertical position along the first and second vertical guides; and an exercise bar coupled to the upper carriage portion of the first and second carriages, the exercise bar operable to translate or rotate to actuate the carriage locking mechanism.
