An operating unit is connectable with the first cables.

A safety signal is sent to a relay coupled to a plurality of power leads of a motor wherein a default state of the relay is to short the plurality of power leads together and wherein the safety signal maintains the relay in an open state. The safety signal to the relay is deasserted in response to a determination that an unsafe condition has occurred.

A paddling simulator includes a bar, a cable attached to the bar, a motor operationally coupled to the cable such that the motor can apply a force to the cable, and a controller configured to control the motor to generate a first tension in the cable during a propulsion phase of a paddling stroke and a second tension in the cable during a recovery phase of the paddling stroke.

An exercise machine is disclosed. The exercise machine comprises a motor. The exercise machine comprises a gearbox coupled to the motor, wherein the gearbox comprises bevel gears. The exercise machine comprises a spool coupled to the gearbox. The exercise machine comprises a cable wound about the spool. A second exercise machine is disclosed. The second exercise machine comprises a motor. The second exercise machine comprises a lockable translatable mount. The second exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The second exercise machine comprises a sensor coupled to the lockable translatable mount, wherein the sensor is used at least in part to determine mount lock state. A third exercise machine is disclosed. The third exercise machine comprises a motor. The third exercise machine comprises a mount. The third exercise machine comprises a cable coupled to the motor via the mount. The third exercise machine comprises a sensor coupled to the mount, wherein the sensor is used at least in part to determine mount lock state. The third exercise machine comprises a lockable arm coupled to the mount and a second sensor coupled to the lockable arm, wherein the second sensor is used at least in part to determine arm angle.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

The present disclosure describes an exercise device including a first base and a second base. The first base includes a pair of support handles rotatably connected to the first base, a pair of cable arms rotatably connected to the first base, wherein the pair of cable arms include a first engagement mechanism, an electronic resistance device connected to a pair of cable handles via a pair of cables that pass through a pair of channels defined by the pair of cable arms; and a seat. The second base includes a beam affixed to and connecting the first base and the second base. The beam includes a track, a backrest carriage that is slidably engaged with the track and includes a second and third engagement mechanism, and a backrest rotatably connected to an end of the backrest carriage.

A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.

An apparatus includes a pair of support members, a cable, a rolling mechanism, a tackling bag and a pulley device. The pair of support members are fixedly coupled to a surface. The cable is attached to and extends between the pair of support members. The rolling mechanism is connected to the cable and configured to traverse the cable from a first end of the cable toward a second end of the cable. The tackling bag is attached to the rolling mechanism and configured to be propelled from one of the pair of support members toward the other of the pair of support members. The cable passes through a pulley system which is couple to a stack of weights. When the tackling bag is tackled, the stack of weights provide resistance to the tackler.
