An exercise machine may include a frame with set of foot pedals mounted thereon. A seat-receiving space is defined by the frame rearward of the set of pedals and a seat that is in the form of an inflatable bladder is received within the seat-receiving space. The inflatable bladder is retained within the frame in such a way that the bladder is able to move within the frame when the exercise machine is used. A seat back extends upwardly of and adjacent the inflatable seat and supports a user's back while the user is seated on the inflatable seat. Left and right arms are secured to the frame and extend respectively to the left and right of the inflatable seat. The user may undertake a cardiovascular workout and a core workout of abdominal and back muscles using the exercise machine.

An apparatus for providing therapeutic rehabilitation exercise to bedridden individuals and patients, including comatose individuals. A vertical support column extends upwards from a base, with one or more arms extend from the vertical support column, each providing a rotary mechanism at the distal end, with pedals or handles attached thereto. The individual's feet or hands are secured to the pedals or handles, respectively. Straps, brackets, or other fastening means may be used to secure the feet and hands. An electric motor causes the rotary mechanism to move the pedals or handles in a rotary fashion, thereby providing movement and exercise for the individual's legs and arms.

The wheel attachment for stationary exercise bike is an attachment adapted for use with a stationary exercise bike. The wheel attachment for stationary exercise bike is adapted for use in cross-training. Specifically, the wheel attachment for stationary exercise bike is a rotating handle bar that is mounted on the stationary exercise bike. The wheel attachment for stationary exercise bike is mounted on a pivot that allows the wheel attachment for stationary exercise bike to be rotated in a first plane of rotation that is perpendicular to a second plane of rotation that is defined by the rotation of the pedals of the exercise bike. The wheel attachment for stationary exercise bike comprises a pivot, a handle bar, a strut, and a front tire apparatus.

An exercise apparatus may provide a novel linkage assembly suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right rocker links may be rotatably mounted on a frame rotatable about a first axis. Left and right rocker linkages may be mounted on the frame rotatable about a second axis. Left and right force receiving members may be movably connected between respective rocker links and rocker linkages in such a manner that the force receiving members move through paths of motion which are fixed, adjustable or variable.

An oblong orbital exercising machine includes a main frame, an upright, a seat support, a cycle movement mechanism, two swinging handles, two drive bars, two pedal units and two adjustment units. Each of the pedal units includes a fixing plate, a rocking plate, two springs, two fastening rods and a pedal. Each of the two adjustment units includes a fixed disk, an adjusting disk, two limit stubs, a hollow rod, a hollow mounting sleeve and a positioning pull pin. Thus, when the pedal units are moved in concert with the drive bars, the pedal of each of the pedal units is adjusted to correspond to the oblong trace of movement. In addition, the user can adjust the position of each of the pedal units easily and quickly by operation of each of the two adjustment units.

An exercise apparatus having a cabinet housing to which a telescopically and angularly moveable arm is mounted. A hand pedal assembly is mounted to the arm and drivingly linked to a resistance mechanism. A platform is telescopically mounted to the bottom of the cabinet, and a foot pedal assembly is adjustably mounted to the platform. A seat is mounted to the far end of the platform from the cabinet, and the platform can be moved so the seat, the foot pedal assembly, or at least portions of both, can be inserted into a chamber of the cabinet.
