A report of a state of a local exercise device based at least in part on a user response to an electromagnetic resistance unit in the local exercise device is sent. An update based on a state of a remote exercise device is received. The electromagnetic resistance unit is caused to change state in reaction to the received update.

An apparatus is provided for use in resistance training. The apparatus may include a bar with pulley hubs on its ends. The apparatus may further include two slings, each including connectors and a rigid, straight or arc-shaped bar. The slings may be suspended from the pulley hubs and support an elastic band, which may provide resistance during exercise. A footplate may also be provided to hold part of the band to the floor during use.

A wearable exercise device with adjustable resistance adjustment controls includes a strap having a first fastener on a first end and a second mating fastener on a second end, wherein the strap is configured to removably secure around a user's waist. A housing connected to the strap, which includes a pair of internal spools each operably connected to a spring-loaded resistance mechanism. A cable is affixed at one end to each internal spool. The cables extend outwardly from opposing sides of the housing through a pair of cable openings. A handle is connected to an opposing end of each cable. A pair of resistance adjustment controls disposed on the housing are operably connected to each spring-loaded resistance mechanism. The user can wear the waist strap and grasp the handles to perform arm exercises. The resistance adjustment controls allow the user to independently adjust the resistance of each cable.

According to one example, an exercise system includes a vertical housing, a first weight system coupled to a first upper weighted touchpoint, a second weight system coupled to a second upper weighted touchpoint, a third weight system coupled to a first lower weighted touchpoint, and a fourth weight system coupled to a second lower weighted touchpoint. The exercise system further includes a control system that is configured to cause the first weight system to provide weight to the first upper weighted touchpoint independent of each of the second, third, and fourth weight systems, and cause the third weight system to provide weight to the first lower weighted touchpoint independent of each of the first, second, and fourth weight systems. The first upper weighted touchpoint and the first lower weighted touchpoint may allow the user to exercise the first arm and the first leg of the user simultaneously.

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

An arm exercise apparatus is disclosed which includes a substantially rigid framework having a stand supporting a first, a second and a third frame member, a rod flexibly coupled to the first frame member at a vicinity of a first end of the rod, the rod having a second end opposite to the first end for being held by a user's hand during an exercise, a first elastic band coupling the rod at a predetermined location to the second frame member, the predetermined location being between the first end and the second end and having a predetermined distance to the first end, the first elastic band exerting a first force at the rod, and a second elastic band coupling the rod to the third frame member, the second elastic band exerting a second force at the rod countering the first force, wherein the rod is statically suspended in a space between the second and the third frame member.

An exercise machine is disclosed. The exercise machine comprises a motor, an actuator, an arm, and a cable. The cable is coupled between the motor and the actuator through the arm. The motor is configured to provide a nominal tension of resistance when an end of the cable is within a range of length from a zero point associated with the cable.

A machine for gymnastic exercises includes a gripping element which can be gripped by a user, and a first motor and a second motor able to be commanded independently from each other and each configured to generate respective loads suitable to define a resistant force perceived on the gripping element during a traction exerted on the latter by a user. The machine also includes a sliding guide and a slider installed slidingly on the sliding guide.

An orthostatic hypotension alleviation device comprising an outer casing comprising an aperture extending therethrough; a carriage arranged within the outer casing and configured to be reciprocally displaced towards and away from the aperture along a carriage displacement axis; a spindle arranged on the carriage and configured to rotate about a spindle axis; a tether at least partially wound around the spindle, the tether comprising a distal end extending through the aperture, the tether being arranged such that it can be extended from a retracted configuration to an extended configuration in which the tether is fully extended by pulling the distal end away from the aperture so rotating the spindle about the spindle axis; a spindle biasing mechanism connected to the spindle and configured to apply a biasing torque to the spindle about the spindle axis so as to bias the tether towards the retracted configuration; and, a carriage biasing mechanism arranged within the outer casing connected to the carriage and configured to bias the carriage away from the aperture.

An exercise machine has a main frame and a user support movably mounted relative to the main frame for movement between a start position and an end position during an exercise. At least one user engagement device is movably mounted relative to the main frame for engagement and actuation by a user during an exercise, and a connecting linkage translates movement of the user engagement device to movement of the user support. A lifting arm is movably mounted relative to the main frame and associated with at least one of the user support, user engagement device, and connecting linkage so as to move during an exercise. A load associated with the lifting arm provides exercise resistance.
