The present invention provides a treadmill for allowing an exerciser to perform walking or running exercise on an endless belt. The treadmill is selected to be operated in a forward movement mode or in a reverse movement mode. In the reverse movement mode, a control unit of the treadmill controls a driving device to drive a top surface of the endless belt to slide forward for allowing the exerciser to simulate backward walking. When a detecting device detects that the exerciser enters a warning area in front of a normal range of movement, a reaction mechanism would be triggered to control the driving device to slow down or stop the endless belt. In the forward movement mode, the control unit controls the driving device to drive the top surface of the endless belt to slide backward and to disable the reaction mechanism.

An exercise apparatus comprising a foot support movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to an arc segment selection device that is manually actuatable to enable the user to manually select any one of the plurality of different arc segments, the foot support being interconnected to an arm having a handle manually graspable by the user to reduce or increase power or energy required by the user to move the foot support.

An exercise device providing a fore and aft horizontal component of striding motion that is dynamically user-defined, while providing a vertical component of the motion that is maintained on a predetermined vertically reciprocating path in some embodiments. The exercise device guides the user's foot in a pseudo-elliptical stride path, while providing a dynamically variable stride length that allows the user to move with a natural stride length. The exercise device allows tall and short users to extend or curtail the stride length to match their natural stride lengths. The length of the reciprocating path is dynamically adjusted during the exercise operation without equipment adjustments by changes in the length of the stride input by the user at a pair of foot engagement pads disposed on laterally spaced apart foot support members.

An exercise apparatus comprising a foot support movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to an arc segment selection device that is manually actuatable to enable the user to manually select any one of the plurality of different arc segments, the foot support being interconnected to an arm having a handle manually graspable by the user to reduce or increase power or energy required by the user to move the foot support.

A stationary exercise apparatus includes a frame; two moving members respectively coupled to the frame, one end portions of the moving members located to define a swing axis; two swing members, one end portions of the swing members respectively pivotally joined to the swing axis of the moving members; two supporting members respectively connected to the swing members, wherein one end portions of the supporting members are movably coupled to the frame, the other end portions of the supporting members are respectively joined to the swing members so that one end portions of the supporting members moving along a reciprocating path; and two pedal sets respectively coupled to the supporting members, the pedal sets moving along a first path while the one end portions of the supporting members are reciprocating along the reciprocating path and the other end portions of the supporting members are rotating about a rotating axis.

A composite motion exercise machine includes a control panel which provides a plurality of movement modes and allows a user to issue a command to change the configuration of linkage units of the exercise machine to have the machine perform a movement mode without manual adjustment, so that the pedal of each linkage unit can be moved along a closed trajectory. The control panel also allows the user to finely adjust the trajectory and the resistance associated therewith. The trajectory performed by each pedal of the exercise machine is ergonomic so that the user can be protected from exercise injury.

An exercise apparatus comprising a base; a supporting surface carried by the base, the supporting surface to receive a weight bearing portion of a user's body; a support frame carried by the base; a stationary pelvic belt receiving frame carried by the support frame; a pelvic belt rotatably received within the stationary pelvic belt receiving frame and configured to securely receive a pelvic area of the user's body for rotation therewith; and one or more mechanical force resistors carried by the support frame and operably coupled to the pelvic belt so as to impart resistance to rotation of the pelvic belt relative to the stationary pelvic belt receiving frame.

An adjustable rehabilitation and exercise device, including a rotary member rotatably mounted on a hub; a mount having a ring located adjacent to the rotary member with a lock selectively engageable with the rotary member to lock the ring at an angular position relative to the rotary member, and an arm connected to the ring and extending radially relative to the rotary member and having a movable carriage associated therewith to move radially relative to the rotary member and lockable to position the carriage at a radial position relative to the rotary member; and a patient engagement member connected to the mount and movable with the carriage.

An adjustable rehabilitation and exercise device, including a rotary member rotatable on a hub and having a plurality of elongated and spaced apart elongated mount receivers defined thereon; a mount selectively and movably positionable on a selected one of the mount receivers of the rotary member to select an angular location of the mount, the mount including a sliding member movably positionable along the selected mount receiver to a selected radial location along the selected mount receiver to select a radial location of the mount relative to the hub; and a patient engagement member connectable to the mount and movable with the mount.

An adjustable rehabilitation and exercise device, including a rotary member having a plurality of elongated and spaced apart elongated open-ended slots defined thereon; a mount selectively and movably positionable on a selected one of the slots of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the selected slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The mount has a slide member configured to slidingly engage the slot and a movable plunger located on the slide member, wherein the plunger is movable to engage the slot so as to lock the position of the mount along the slot; and a patient engagement member connectable to the mount and movable with the mount.
