The present invention relates to a multi-functional exercise apparatus, and particularly to a multi-functional exercise apparatus which is safe and allows various exercises with different setups to be performed by means of a single apparatus. The present invention, relating to a multi-functional exercise apparatus provided so as to impart a sense of stability to a user when exercising while at the same time allowing various exercises with different setups to be performed by means of a single apparatus, comprises: a plate-shaped body (A) forming the floor surface and having a space in the interior thereof; fixed frames (100) fixedly disposed upwardly on both sides of the body (A); rotatable frames disposed upwardly on both sides of the body (A); handle parts (200) connected on one side of the rotatable frames and provided so as to be movable forwards and backwards; and a foot plate part rotatably provided on upper surface of the body (A) and connected to the other side of the rotatable frames. The multi-functional exercise apparatus according to the present invention imparts a sense of stability to a user as the rotatable frame comprises a plurality of linked sections and connects the handle parts and foot plate part, allowing the user to exercise by rotating not the entire rotatable frames but only the handle parts which are comparatively short compared to the rotatable frames. Furthermore, each linked section of the rotatable frames is rotatably attached to the handle part or to the side of the fixed frame, allowing the rotatable frames to stably transmit driving power from the handle parts (200) to the foot plate part and to be changed so as to allow various exercises with different setups to be performed.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

A body-building device including a base body, a swing mechanism and a supporter is provided. The base body is used to support the whole body-building device. The swing mechanism is installed on the base body to enable 360-degree rotation in the circumferential direction or swing to any angle off the central axis of the base body. The supporter is installed at an upper end of the swing mechanism and makes direct contact with human body. With force applied by human body, it drives the swing mechanism to rotate or swing, while the swing mechanism generates a corresponding reset force during swing, thus enabling body building. Fitness methods are also provided.

An exercise machine includes a frame, a seat selectively movable with respect to the frame, and a resistance mechanism connected to the frame. The seat is adjustably positioned between an upright position that orients a user in an upright orientation with respect to a pedal assembly when the exercise machine is in an upright exercise mode and a recumbent position that orients the user in a recumbent orientation with respect to the pedal assembly when the exercise machine is in a recumbent cycling exercise mode.

An adjustable rehabilitation and exercise device, including a first rotary member rotatably mountable about a first hub and having a plurality of spaced apart and elongated first mount supports defined thereon; a first mount adjustably positioned on one of the first mount supports; a first patient engagement member attached to the first mount, a second rotary member rotatably mountable about a second hub the opposite the first rotary member, the second rotary member having a plurality of spaced apart and elongated second mount supports defined thereon; a second mount adjustably positioned on one of the second mount supports; and a second patient engagement member attached to the second mount. The first and second mounts are adjustably positionable on the first and second rotary members to enable adjustable positioning of the first and second patient engagement members radially relative to the first and second hubs of the rotary members and angularly relative to one another.

A stationary exercise machine in accordance with some examples herein may include a frame, a crankshaft rotatably supported by the frame, an upper moment-producing mechanism and a lower moment-producing mechanism both operatively engaged to the crankshaft to cause the crankshaft to rotate. The lower moment-producing mechanism and the upper moment-producing mechanism may be resiliently coupled to one another, such as via a resilient coupling between a crank arm of the lower moment-producing mechanism and a link or virtual crank arm or the upper moment-producing mechanism. The exercise machine may further include a measurement apparatus which may be configured to measure differential forces between the upper and lower mechanisms.

A portable sit-stand elliptical exercise machine includes a seat, a transmission wheel installed at the seat, two linkage mechanisms installed at the transmission wheel, and two mobile pedals respectively installed at the linkage mechanisms. Each linkage mechanism includes a driving portion connected to the transmission wheel, an axle portion disposed at one side away from the transmission wheel, and an adjustment portion disposed between the axle portion and the driving portion. Each mobile pedal is pivotally connected to the axle portion and includes a plurality of assembly portions. Thus, an angle is formed between each mobile pedal assembled to one of the assembly portions and the linkage mechanism to facilitate a user to utilize the portable sit-stand elliptical exercise machine in either a sitting or standing posture, thereby solving issue of a conventional solution that cannot be applied for a dual use of both sitting and standing postures.

The invention relates to an elliptical trainer including: a frame having a first end and a second end; a rocker-rod mechanism hingedly connected to the first end of the frame; a pedal mechanism hingedly connected to the second end of the frame through a transmission mechanism; an adjustment mechanism including an adjustment table, one end of the adjustment table being rotatably connected to the frame, the pedal mechanism being slidably connected to the adjustment table, the adjustment mechanism adjusting the position of the pedal mechanism relative to the frame; and a link the two ends of which are connected to the rocker-rod mechanism and the pedal mechanism respectively so that the rocker-rod mechanism is linked with the pedal mechanism. Since the apparatus of the invention is provided with an adjustment mechanism which is rotatably connected to the frame and the pedal mechanism is slidably connected to the adjustment mechanism, an exercise experience that the user simulates climbing by means of the pedal mechanism can be improved by changing an elevation angle of the adjustment mechanism relative to the frame. In the apparatus of the invention, a resistance adjustment mechanism is provided on a flywheel, the user can obtain more exercise experiences by increasing rotation resistance of the flywheel and a turntable.

A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank arm extending away from a rotational axis of the crank wheel, and a pedal beam connected to the crank arm. A linkage assembly is connected to the frame at a fixed frame location and to the pedal beam at a fixed pedal beam location. A first linkage member of the linkage assembly has a length that forces the pedal beam to travel along an elliptical path as the crank wheel rotates.
