A weightlifting system includes a frame with lower, middle, and upper pulley stations mounted therein. A load attachment structure is provided within the system. A cable-pulley system includes a plurality of fixed pulleys mounted to the frame, first and second moveable pulleys, and a floating load pulley mounted to the load attachment structure. A plurality of cables is collectively routed through the first and second movable pulleys, the plurality of fixed pulleys, the floating load pulley, and the lower, middle, and upper pulley stations. When a first pulling force is applied to a first cable end accessible from the lower pulley station, the first movable pulley and the load pulley translate. When a second pulling force is applied to a second cable end accessible from the upper pulley station, the second movable pulley and the load pulley translate. When a third pulling force is applied to a third cable end accessible from the middle pulley station, only the load pulley translates.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.

Apparatus for performing a pull down exercise comprising: a frame, a seat, an input arm assembly interconnected to a resistance mechanism and a manually graspable mechanism disposed vertically above the user's trunk in a start sitting exercise position, the input arm assembly being pivotably mounted on the frame for back and forth travel along a generally forward to rearward direction and along a generally side to side direction orthogonal to the forward to rearward direction, the input arm assembly being rotatably pivotable around a first linear axis and a second linear axis in the respective directions on exertion by the user of a rearwardly downwardly directed force on the manually graspable mechanism.

Generally discussed herein are devices, systems, and methods for smart weight-lifting devices. A weight-lifting pin may be configured for insertion into a weight plate of a weight-lifting machine, the weight-lifting pin comprising a radio transmitter, a movement sensor, and a distance sensor.

A more efficient exercise system can be facilitated by interactive components. A system can comprise receiving distance data, from a wireless network device, associated with a selection of a weight of an exercise machine. Based on the distance data, the system can generate resistance data representative of a resistance associated with the exercise machine. Additionally, in response to the generating the resistance data, the system can assign the resistance data to a user identity associated with a mobile device.

Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

An exercise apparatus for performing a back extension exercise comprising: a frame, a seat having a seating surface (PS) and a pelvic stabilization pad having a lower back engagement surface (ES), an input arm assembly interconnected by a first interconnection to a first resistance mechanism, the input arm assembly including a manually graspable mechanism and being arranged on the apparatus such that the input arm assembly is pivotable beginning from a start motionless position along a path of travel forwardly away from the pelvic stabilization pad under resistance exerted by one or both of the resistance mechanisms, wherein the first resistance mechanism is adapted to increase resistance as the degree of pivoting of the input arm assembly increases along the path of travel forwardly away from the pelvic stabilization pad.

An assisted chin/dip exercise apparatus has a main frame and an assist or foot bar pivotally mounted on the frame and linked to a weight stack or resistance for assisting a user standing on the foot bar during performance of chin and dip exercises. The main frame has a first, overhead handle assembly and a second, dip handle assembly below the first handle assembly. The first handle assembly includes a pair of adjustably mounted handles freely pivotable between a first, chin-up position in which the handles extend towards one another at a rearward angle with a small spacing between the handles and a second, pull-up position in which the handles extend in a forward direction and are spaced apart by a larger spacing sufficient to provide head clearance for a user stepping onto the foot bar or while performing a dip exercise.

A weight training machine according to the present invention is a machine for conducting a dead lift or a bent over row while selecting and increasing/decreasing the weight, the machine comprising: a pair of body units, on which weight plates are stacked in the upward/downward direction, and which are provided on both sides of an operating unit, respectively; an operating unit, which is provided between the pair of body units, and which can move in the upward/downward direction; and a cable pulley unit for connecting the body units and the operating unit to each other such that, as the operating unit is moved in the upward/downward direction, the weight plates can be moved in the upward/downward direction, wherein, as the user operates the operating unit in the upward/downward direction and thereby moves the cable of the pair of cable pulley units, the user accordingly moves the weight plates on the body units, which are connected to the cable, thereby conducting weight training. The present invention, as described above, advantageously can provide a weight training machine, which is the purpose of the present invention, configured such that, when the exerciser wants to conduct a dead lift, a bent over row, etc., during weight training, the weight can be easily increased/decreased, and the basic postures can be easily learned, thereby reducing injuries.

An exercise machine for performing prone leg curl exercises, including a moving support platform or frame that allows a user to perform prone leg curl exercises without excessively arching his or her lower back.
