An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

A pedaling exercise device includes a rotation mechanism configured to pivotally support a rotation shaft to allow rotation, a pair of cranks having first ends connected to both ends of the rotation shaft of the rotation mechanism, respectively, a pair of links having first ends rotatably connected to second ends of the cranks, respectively, and having second ends provided with wheels, respectively, a pair of pedal portions connected to the links along a longitudinal direction of the links, respectively, a rolling surface connected to a first end of the rotation mechanism on a user side, and a restriction portion configured to restrict separation of the wheels from the upper surface of the rolling surface in a case where the first end of the rotation mechanism is lifted such that the rotation mechanism is erected in a state where a second end of the rotation mechanism is grounded.

A usage condition proposal system includes a storage medium that stores a reference DB having a plurality of pieces of causal relationship information that includes training information and variation range information, the training information including physical information for a user and usage condition information for a training machine, variation range information indicating a variation range of a joint angle of at least one joint of the user when the user trains using the training machine based on the usage condition information. A processor is configured to extract, with reference to the reference DB, based on the physical information and the specified variation range information, the causal relationship information of which the variation range information indicates the variation range satisfying a predetermined relationship with the specified variation range.

A muscle activity output system includes: a muscle activity database configured to hold movable part attitude information and muscle activity information in such a manner that the movable part attitude information and the muscle activity information are linked to each other; and a processor. The movable part attitude information indicates an attitude of a movable part of training equipment. The muscle activity information indicates a muscle activity of each of muscle sites of the exerciser. The processor is configured to acquire the movable part attitude information while the exerciser is moving the body along the trajectory, acquire current muscle activity information for each of the muscle sites based on current movable part attitude information of the training equipment and the muscle activity database, and output the current muscle activity information for each of the muscle sites.

A high knees exercise apparatus includes a base, a driving mechanism, a linkage mechanism and two magnetic resistance. The driving mechanism is located on the base and includes two driving member which is driven swung along arc path. The linkage mechanism is for leading the driving members swung reversely in response to each other. The two magnetic resistance devices are for providing magnetic resistances in accordance with swings of the two driving members respectively.

The invention according to the application relates to a locomotion therapy and rehabilitation device developed for patients whose locomotion function is either lost or declined due to spinal disorders, orthopaedic surgeries and central nervous system disorders to redevelop and improve their walking ability.

An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.

An exercise device includes a frame, an upright portion of the frame, a movable element connected to the frame and movable in the performance of an exercise, a first display connected to the upright portion of the frame, and a second display connected to the frame.

An exercise device includes a frame, a movable engagement surface connected to the frame and movable in the performance of an exercise, and a display located adjacent to or below at least a portion of the movable engagement surface.
