Other embodiments include chair fixing mechanism (14), (14a) to hold the device from moving, and stepper mechanism (11a), (11b), (22a), (22b) and varied track direction (12c) for diverse exercise of the user.

An exercise device comprising: a frame having a generally vertical planar axis, first and second foot supports suspended on the frame by first and second linkage assemblies that are respectively arranged on the frame such that the first and second foot supports are pivotable through a front to back arcuate path of travel that is disposed at a selected angle between about five and about forty five degrees relative to the vertical planar axis.

An exercise device featuring a pair of knee joints, each pivotally and respectively coupled to a pair of calf linkages, each of the pair of calf linkages having a foot pedal at an opposite lower end that supports low impact user-defined natural exercise gait patterns. The knee joints are supported and directed to travel by linkage and/or carriage systems that operate substantially below a user hip area, and direct the knee joints in a variety of travel paths, ranging from a constant arc, to a linear pathway, to a variety of irregular arc shaped paths, to pathways that may change during use. A secondary system coupled to the linkage and/or carriage systems provides lift and dampening forces to influence a responsiveness of the foot pedals via bending and straightening of the calf linkages about the respective knee joint, yet does not restrict back and forth travel of the respective knee joint.

The invention relates to the field of sports and medicine, specifically to training devices, more particularly to an elliptical exercise device suitable for simultaneous training of shoulder and pelvic girdle muscles in a human. Accordingly, it is desirable to provide an exercise device for training trunk muscles, the shoulder girdle and the pelvic girdle in a human and, at the same time, to enable simulation of various motion patterns by activating different groups of muscles, joints, the locomotor system in a human in general and especially muscles which hold the vertebral spine. It is further desirable to enable optional correction of their load during the process of coordination of motor activity (locomotion) of the human body through simultaneous elliptical motions of hands and feet, which, in addition to the load on the shoulder girdle and the pelvic girdle muscles, simultaneously provide preferably stretching load on muscle groups which hold the vertebral spine.

A training bicycle, including a first frame (1, 36) configured to be supported on a floor, a second frame (2, 37) connected to the first frame, the second frame including an axle (4) allowing the second frame to tilt relative to the first frame along an axis in the longitudinal direction of the training apparatus, a handlebar (12, 35, 77, 90) connected to the upper end of a steering shaft (11, 76), the steering shaft being rotationally connected to the second frame, a crank (26, 110) connected to the second frame, and a first flywheel (22, 41, 56, 167, 193) rotationally connected to the lower end of said steering shaft with means for transferring movement from the crank to the first flywheel.

An improved exercise device includes pedals configured to move in counter-rotating circles in a plane inclined toward the horizontal from the vertical at an angle greater than 0 and less than or equal to 90. The device includes a supporting frame, a pedal mounting assembly attached to the supporting frame at an angle from the vertical, two pedal supports attached to the pedal mounting assembly, each via a pedal crank assembly, at an angle to the vertical, and two pedals, one pedal supported by each pedal support.

The exercise device includes an elevated base, including a single track, diverging forwardly into a plurality of elevated arms, each including an elongated track member disposed between opposing first and second ends such that the first end is proximal to a forward end of the elevated base. An elevated beam provided with a stationary knee support protrudes rearwardly from the elevated base. A single slider including a steering mechanism is capable of being slidably disposed on the single track and selectively disposed onto an elongated track member of any one of the plurality of elevated arms. Preferably, a plurality of legs are used to elevate the plurality of elevated arms, elevated base and elevated beam from a supporting surface.

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 featuring a pair of knee joints, each pivotally coupled to a pair of calf linkages having foot pedals at their opposite lower end that support low impact user-defined natural exercise gait patterns. The knee pivots joints are supported and directed to travel by linkage and/or carriage systems that operate substantially below the user hip area, and direct the knee pivot joints in a variety of travel paths, ranging from having a constant arc, linear pathway, to having a variety of irregular arc shaped paths, as well as, pathways that may change during use. A secondary system coupled to the knee pivot support system, provides lift and dampening forces to influence the responsiveness of the foot pedals via the bending and straightening of the calf linkage about the knee pivot joint, yet do not restrict the back and forth travel of the knee joint.

An exercise apparatus comprises a frame, left and right foot link supporting left and right foot pads. The left and right foot pads synchronously move out of phase through an elliptical path having an adjustable step height. The apparatus may include left and right side arms pivotally connected to the left and right foot links and pivotally supported by the frame. Left and right cranks eccentrically support left and right crank guides. Left and right links each have a first end pivotably connected to left and right foot links and a second end operably coupled to the left and right crank guides, respectively. A movable adjustment member is connected to left and right flexible members operably coupled to the left and right foot links. Movement of the adjustable member adjusts an extent to which the left and right flexible members wrap about the respective left and right crank guides.
