A symmetric upright rotating disc exercise machine includes a base unit and two upright rotating disc units. Each upright rotating disc unit includes a rotating shaft, an upright disc, and a grip. The rotating shaft is pivotally connected to the base unit in a horizontal direction. The upright disc is mounted to the rotating shaft. The upright discs of the two upright rotating disc units are arranged to face each other. The two upright rotating disc units are separated from each other by a distance in the horizontal direction to form an operation space. The grip is mounted to the upright disc and located in the operation space.

An exercise apparatus includes a base configured to rest on a horizontal floor surface. A vertical pole member is fastened to the base and extends vertically from the floor surface. A cross bar sleeve is fastened to an upper end portion of the vertical pole member and supports a pair of cross bar members extending in opposite directions. One or more elastic resistance members extends from the cross bar members. A rectangular foot support plate is removably supported on the base. This rectangular foot support plate has a pair of spaced apart lugs projecting from an underside surface of the foot support plate along one edge. Each is adapted to fit within one of a plurality of recesses in the base so as to incline the foot support plate at an angle with respect to the base when the foot support plate is supported on the base.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

An ankle exerciser for exercising a user's ankles and includes a base, two pedals and two rotary units. The pedals and the rotary units are installed to the base. The rotary units are located between the base and the pedals so as to allow the pedals to be pivoted in multiple directions so as to stretch the ankles, and to keep ankles healthy.

A portable exercise device provided includes: a base disc, two pulley assemblies, a support plate, and a fan wheel assembly. A support plate is disposed on the base disc, the two pulley assemblies are provided on the base disc, and the fan wheel assembly is provided on the support plate, so that the fan wheel assembly and the two pulley assemblies are vertically arranged on top of each other, thereby reducing the overall volume. More preferably, because the volume is reduced, the user can arbitrarily move and hang the portable exercise device at the desired position, and because the portable exercise device of the invention can be hung at different positions, which allows the user to train different muscles according to the different positions.

A multifunctional fitness device comprising a fitness device body, a support arm and an intelligent control system, with a display device being disposed on a front surface of the fitness device body, the display device being a mirror display screen having functions of video teaching and ordinary mirror, a camera device being disposed at the top of the display device, and the camera device including a micro-camera and an infrared camera, support arms being disposed at both sides of the fitness device body through sliding rails respectively, a gear groove being disposed on the support arm, a gear fixing device for use in cooperation with the gear groove being disposed on the sliding rail, a rope being disposed inside the support arm, the other end of the rope being connected with an intelligent motor, which motor produces resistance to provide a resistant force to the support arm.

An exercise apparatus having a frame with attachments to multiple independent bidirectional resistance devices used by arms and/or legs of a user to provide resistance against movement of the user's appendages in two substantially opposed directions. The resistance devices may have a mechanism to control bi-directional resistance. The movement of the user's appendages in bi-directional resistance offers near full body exercise of agonist/antagonist muscles using flexion and extension action of larger muscle groups in a gait pattern, simultaneously. Hand engaging members attach to arm resistance devices and foot engaging members attach to leg resistance devices. The exercise apparatus may include an attached inclined backboard, mat, bench, or cushion to fully or partially support the user. The exercise apparatus may have separate height and/or length adjustment mechanisms for adjusting a range of motion of the user's appendages.

An exercise or training device that includes a first pulley, a second pulley, and a two ended line trained through the first and second pulley, the line having a first end and a second end, the first end of the line affixed to a first handle for gripping, a second handle for gripping affixed to the line at a position between the first end and the second end of the line. The pulleys may be fixed in position to a wall or rack such that they are horizontally spaced apart. In some embodiments, the pulley or pulleys may be attached to the fixed position by a spring assembly or other device to increase the linear force in the handles or bar.

An adjustable reformer for exercising is provided. The reformer includes a frame, a carriage slidably mounted to the horizontal frame, and at least one resistance element connected to the carriage. A cord connects the carriage to at least one lower guide and at least one upper guide. Pulling the cord causes movement of the carriage along the frame against resistance provided by the resistance element. The guides can be height adjustable. The reformer can include a cord retraction system. Related methods of exercise are also provided.

A fitness device contains a strap, a handle, and a plate. The strap is substantially inelastic and flexible. The plate is substantially rigid. The handle at least partially envelopes the strap. A method of exercising with such a fitness device is also described herein. Other fitness devices and other methods of use are also described herein.
