A back exercise machine includes: a resistance element; a user support; a first movement element, the first movement element having: a column; and a first connecting element having a pivot point such that the user support is able to pivot about a first axis associated with the first connecting element, wherein the first connecting element is movably coupled to the column such that the first connecting element is able to move along a path defined by the column; and a second movement element, the second movement element having: a rail; and a second connecting element having a pivot point such that the user support is able to pivot about a second axis associated with the second connecting element, wherein the second connecting element is movably coupled to the rail such that the second connecting element is able to move along a path defined by the rail.

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.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

The exercise machine with a variable resistance system includes a frame, an exercise implement movably connected to the frame, a main shaft rotatably connected to the frame, a main connector attached between the main shaft and the exercise implement, a plurality of resistance assemblies and a plurality of actuation assemblies adapted for selectively engaging or disengaging at least one of the plurality of resistance assemblies with respect to the main shaft. The plurality of resistance assemblies apply a total level of rotational resistance against the main shaft based on which of the plurality of resistance assemblies are engaged with the main shaft by the plurality of actuation assemblies.

A movable cable head adjustment compensation assembly may include one or more of a first pulley configured to receive a head adjustment cable, a second pulley configured to receive a resistance cable, and a stabilizer. A movable cable head adjustment compensation assembly may include a connecting plate coupled to the first pulley, the second pulley, and the stabilizer. A cable head adjustment apparatus may include a cable head, a movable cable head adjustment compensation assembly, a head adjustment cable, a resistance cable, a cable drum, and a lower pulley.

An adjustable reformer for exercising is provided. The reformer includes a frame, a carriage slidably mounted to the horizontal frame, and at least one resistance element connected to the carriage. A cord connects the carriage to at least one lower guide and at least one upper guide. Pulling the cord causes movement of the carriage along the frame against resistance provided by the resistance element. The guides can be height adjustable. The reformer can include a cord-length adjustment system. Related methods of exercise are also provided.

A resistance exercise system having, in certain embodiments, a DC power supply system, a DC motor connected to the DC power supply system, a drive section connected to a drive element, a resistance delivery element connected to the drive element, and an extractable exercise resistance delivery section, a predetermined variable resistance section intermediate the DC power supply system and DC motor, an electrical condition sensor, and a variable resistance section control in communication with the electrical condition sensor and the predetermined variable resistance section. In some embodiments, the resistance exercise system includes a computing facility providing the ability to configure the exercise system to provide predetermined static or variable exercise resistance during exercise, and for example, during a positive or negative exercise stroke. Some embodiments allow users to create and, if desired, display varying and complex resistance exercise routines with or without use of resistance weights.

A shoulder end range of motion improving device has a linkage, the linkage including a first link member, a second link member supported on the first link member, the second link member configured for being secured to an arm of a patient and being rotatable about a second link axis for rotating the arm of the patient about a shoulder joint of the patient through an arm range of motion, the second link axis being displaceable into a selectable fixed position, the fixed position being maintained during rotation of the second link member, an actuator for rotating the second link member about the second link axis, and a controller controlling the actuator for selectively rotating the second link member about the second link axis through the arm range of motion.
