A first determination that a range of motion of a user of an exercise machine is between pre-determined motion thresholds is made. While the range of motion of the user is between the pre-determined motion thresholds, a velocity of the cable being below a pre-determined velocity threshold is determined. In response to determining that the velocity of the cable being below the pre-determined velocity threshold while the range of motion of the user is between the pre-determined motion thresholds, a second determination that the user should be spotted is made, Torque of a motor is reduced based at least in part on the second determination that the user should be spotted.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

Disclosed exercise machines provide adaptive resistance in both directions of cable or flexible member movement. Perceived or felt resistance increases in response to the effort and/or speed of movement exerted by a user. During exercise, a user may become fatigued making further movement or weight support unwanted. With the disclosed embodiments, a user may simply stop their effort and the resistance and movement of the machine will stop. There are no plates or physical weights to harm a user and operation of the machine occurs in near silence. The disclosed embodiments are well suited for both beginner and accomplished athletes as the resistance adjusts seamlessly and continuously to match the force exerted by the user.

The present disclosure provides a rope-type conditioning/exercise apparatus that provides movements and resistance similar to prior devices requiring significantly longer ropes by providing ropes that are connected to sliders on sliding tubes, wherein the resistance to upward and downward movement of the sliders can be adjusted as desired by a user to create.

An exercise device (100) is supportable by a swivel mount (116) attached to a karabiner (114) and the swivel mount is arranged to lock under load at 90 increments. The device includes a rotatable reel (103) arranged to have a pair of inelastic straps (113a, 113b) rotationally wound thereabout from opposite directions. The reel is rotatable in conjunction with a locking mechanism consisting of a toothed sprocket wheel (104) secured to the reel and a manually operable slideable shaft (106) that is located within a barrel (107). Slots (136, 139) in the shaft and barrel, respectively, permit rotational movement of the sprocket wheel and, hence, reel (103) so that the straps (113a, 113b) may have their length altered against the bias of a coil spring unit (111). Translational movement of the shaft (106) within the barrel (107) causes the full diameter of the shaft (106) to engage between adjacent teeth of the sprocket wheel to lock the reel (103), thereby preventing further adjustment of the straps (113a, 113b). When the reel is released for rotational movement, so pulling on one or both of the straps against the bias of the spring unit causes the straps to be unwound evenly and reducing the pulling force below that of the spring unit causes the straps to be rotationally wound around the reel from opposite directions.

An exercise apparatus has at least one vertical wall structure, a floor and a ceiling forming a cage that can be square, rectangular, circular, oval or another suitable configuration. An arrangement of strategically placed attachment points on the wall structure, floor and ceiling enables easy attachment and detachment of a variety of resistance devices (e.g., a handheld and/or inline cable operated resistance creation device, or a stretch band resistance device) to any of the vertical and/or horizontal structures within the gym cage, thereby providing a nearly 360 degree dimensional point of resistance to perform a wide variety of exercises for different muscle groups and subgroups of the body. In one embodiment, the cage includes an arrangement of spaced apart vertical and horizontal frame members forming a rear wall and opposite side walls.
