A portable exercise device that allows a person to do Pilates type exercises without using traditional, cumbersome equipment. The device uses a pair of wheel assemblies each attached to each end of a central shaft. The shaft height can be adjusted from the center of each wheel to a lower point closer to the ground. Adjustable cam lockable hand/foot plates are attached to the shaft allowing the user to attach his or her feet to the shaft. Each hand/foot plate assembly includes a rotational plate that allows the hand/foot plate to be positioned at various angles in relation to the shaft. Resistance bands are attached on one side to the shaft and on the opposite side to a resistance source. The resistance source can be the user's own hands or feet, or a retaining strap attached to the lower portion of a door or wall.

An exerciser, preferably in the form of a stepper with a fluid resistance system guides stepper treadles angularly downward and outward from the center of the stepper. According to an embodiment bellows that support treadles angle downward and outward.

An elliptical machine includes a machine frame and two pedal units each including a vertical arm having a top end pivotally connected to the machine frame and swingable back and forth, a driving main arm having a front end arranged on an opposing bottom end of the vertical arm in a vertically swingable manner, a pedal mount arranged on an opposing rear end of the driving main arm and swingable left and right, a pedal arranged on the pedal mount and swingable left and right, a slanting rod having a front end arranged on the vertical arm in a vertically swingable manner and an opposing rear end arranged on the pedal mount in a universally rotatable manner, and a rocking link that has a front end arranged on the rear end of the driving main arm and swingable back and forth and up and down.

A leg exercise machine includes a frame and a swinging mechanism. The swinging mechanism includes two parallel tubes, four swinging rods and two pedals. The tubes are supported on the frame. Each of the pedals is connected to two corresponding ones of the swinging rods. Each of the universal joints connects a corresponding end of a corresponding one of the tubes to an upper end of a corresponding one of the swinging rods.

A gymnastics apparatus, comprising an at least semicircular arc structure which is adapted to define a pair of rails along which at least one body can move on which at least one cable can be unwound and wound, in contrast with a resistance, said cable being adapted to be gripped by a user who positions himself or herself proximate to the at least semicircular arc structure.

An elliptical exercise device has a frame and guide link pivotally attached thereto. A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. A cam drive has cams supported for rotation about an axis of rotation and pivoting arms each engaging one of the cams such that rotation of the cams causes movement of the pivoting arms. Flexible elements couple the foot support links to the pivoting arms such that rotation of the cams moves the foot receiving areas of the respective foot support links in a path of travel having a vertical component of motion.

A stepper exercise machine is provided. When a pedal is pedaled by a user, a drive gear is rotated forward or rearward. One end of a link is rotated about a drive rod, and a turning lever connected to the other end of the link is confined by a second accommodation trough of the pedal, so that the link brings the pedal to move in the up-down direction and the front-rear direction. In cooperation with a shaft which is fixed, a sleeve is rotatable relative to the shaft. When the pedal is driven, a first accommodation space provides a space for the pedal to move in the front-rear direction. By means of the action of two flywheels to provide an acceleration effect, the rotation of the drive gear is to speed up, so that the user can reduce the force exerted to the pedal.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.

A spinal treatment system includes a traction device, an exercise device adapted for imparting curvature to the lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force, and a cushion coupled to the traction device and configured to bear against one or both of a head of the user and the thoracic spine of the user. The exercise device includes a frame for placement on the floor. A pad or inflatable bladder is carried by the top surface of the frame. A body strap attachment portion encompasses the thoracic-sacral spinal vertebrae region of the user and secures the frame to the user. The cushion includes one or more pad sections or inflatable bladder sections.
