A free-weight bench (10) is provided having a safety assist device (12) for preventing injury to a weight lifter who repetitively lifts a barbell weight (16) including a weight bar (42). The safety assist device (12) includes a pair of spaced apart arms (32,34) oriented to permit the bar (42) to move along the length thereof, and a bar-sensing apparatus (45) comprising a plurality of sensors (46) on the arms (32,34) as well as a processor (60) programmed to determine at least one parameter related to the velocity of the bar (42) as it moves along the arms (32,34). Respective extensible supports (47) comprising fluid-actuated piston and cylinder assemblies (48,50) are located adjacent corresponding arms (32,34) and are controlled by the processor (60). In the event that a lifter loses control of the barbell weight (16) causing the latter to rapidly descend, the processor (60) receives bar-position signals from the sensors (46) and calculates a velocity-related parameter; the processor (60) then initiates operation of the supports (47) in order to arrest the downward descent of the barbell weight (16) to prevent injury to the lifter.

The present invention relates generally to exercising equipment, and more particularly, to an improved multi-use weight lifting apparatus. The present weight lifting apparatus comprises a frame (12), a vertical guide member (52), at least one horizontal guide member (46), a weight bearing bar (60), and a safety catch mechanism (70). This weight lifting apparatus allows a weight lifter to perform exercise with vertical and horizontal ranges of motion that simulate the natural motions of using free weights while providing safety mechanisms that are not available with free weights.

An embodiment of a barbell and dumbbell safety spotting apparatus is a weight support cable (34a) wrapped around a rotating drum (44a) with the drum is mounted vertically above a weight lifter. The cables are connectable to a barbell assembly (24) or dumbbell assembly to provide reciprocating vertical movement of the weight assembly in a free-weight fashion. The drum has a ratcheting mechanism (55) that normally prevents downward movement of the weight assembly. The ratchet is connected to a user-operated control mechanism (28) so that the user can disengage the ratchet, allowing the weight assembly to be freely lowered. Other embodiments are described and shown.

A chest and arm exercise device provides a chest spanning elastic member including a rubber sheet connected to a pair of elastic arm cuffs. A weight lifter's shirt includes a fabric body covering including an elastic chest spanning member and a pair of elastic sleeves or cuffs.

A weight-lifter bench is equipped with a removable body support pad having a multiplicity of body support cavities in the pad upper surface. These cavities mate with rear surfaces of the person's head and torso when the person is in a lithotomy position, e.g. when the person is performing a weight-lifting activity using the bench. The cavity surfaces conform to the body surface contours, such that essentially the entire rear surface of the person's torso is in contact with the pad. The pad provides a comfortable support surface, and an enhanced body support action that tends to minimize the potential risk for injury or fatigue.

In several embodiments, an athletic garment is designed to store energy when a weight or load is lowered in order to assist the wearer to subsequently raise the load. In some embodiments, the garment provides seams which are curved in order to twist the garment fabric and thereby store energy therein. In one shirt embodiment, the sleeves extend perpendicularly forward of the torso and then converge toward a centerline of the shirt. In a second shirt embodiment, the sleeves extend perpendicularly forward of the torso for their entire length. In a weight lifter's suit embodiment, the curved seams extends from an armhole of a torso section to a location under the buttocks of the lifter. In another shirt embodiment, the arms extend forwardly of a vertical plane when the wearer is lying on the back in preparation for an arching bench press movement.

A safety mechanism for weightlifting devices checks the uncontrolled descent of weights and / or other structures. Using aligned or other slots, a pawl or dog is biased against the surface containing such slots. In order to operate the weightlifting device, the pawl or dog must be actively disengaged from the slots. Exercise can then occur. However, should the weightlifter's grip relax and release the release lever, the associated biasing system forces the engagement end of the dog into one of the aligned slots halting the further downward travel of the associated weights in supporting structures. An associated weightlifting device is disclosed having a latching mechanism enabling securement of the device in a lowered position.

A system and methods for a machine learning exercise belt comprising a belt, gyroscope, accelerometer, pressure sensor, electromyography (EMG) sensor and wireless adaptor, which may use machine learning algorithms and network communication to determine a weight lifter's form and intensity during exercise and provide feedback if they are performing an exercise with poor form, to help avoid injury and other consequences from poor form during weight lifting exercises.

A weight lifting power cage for use by a weight lifter includes a floor frame assembly including a pair of side floor frames, a front lateral floor frame member, and a rear lateral floor member. A carriage is carried by the side floor frames and is movable simultaneously vertically and front to back. The carriage retains a weight bar mount for retaining a weight bar spanning between each side frame. The weight bar is movable by the carriage vertically and front to back. The movable carriage also carries a pair of vertical weight rack bars. An engagement mechanism enables the weight lifter to rack the weight bar from a weight lifting position without stepping forward or backward.

A weight horn is supported on a bearing housing that slides along two vertical guide rails. The upper and lower ends of the vertical guide rails are connected to tubular sleeves that slide along horizontal guide rails, which are enclosed by a rectangular frame. A roller pad extends from the opposite side of the weight horn, perpendicular to the horizontal guide rails and over a platform containing an adjustable seat, calf support and foot pads. The weight lifter performs the movement by standing upright with his / her legs positioned between the calf support and foot pads, wrapping his / her arms around the roller pad, and squatting onto the seat. The combination of vertical and horizontal guide rails allows the weighted roller pad to travel a curved path downward and backward as the lifter descends into the squat position. The dual rail configuration for both the vertical and horizontal guide rails prevents jamming of the mechanisms if the weight lifter twists his / her torso during the squat.
