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 muscle training system according to the present invention includes a belt that is provided with a gas bag and configured to apply a pressurizing force based on an amount of a gas in the gas bag to a specific portion of four limbs of a user in a state of being wound around the specific portion, a control device that receives a control command transmitted from the outside and is configured to control the pressurizing force to be applied by the belt to the specific portion by controlling a supply amount and a discharge amount of the gas to the gas bag of the belt based on the control command, and a portable information terminal device that is configured to transmit the control command to the control device by wireless communication in a case of operating in a predetermined aspect.

An exercise apparatus comprising a weight stack, a flexible elongated cable having a downstream portion that is interconnected to a user selectable number of the one or more individual bodies of weight and to a second resistance device, a manually movable actuating device interconnected to a proximal end of the cable, a downstream portion of the cable being interconnected to the one or more individual bodies of weight and to the second resistance device in an arrangement that pulls on both the one or more individual bodies of weight and the second resistance device.

An exercise device including two foot platforms riding on elongated rails for longitudinal motion relative thereto. The platforms are directly connected to each other by one or more elastic elements. One or more dampers are installed substantially parallel with the elastic elements to oppose the energy return of the elastic elements. When the two platforms are side-by-side, the elastic elements and dampers run in a substantially crosswise direction. A seated user may place feet on the platforms and move his/her feet and lower legs back and forth in a scissoring motion to move the platforms in opposition directions along the rails. In so doing, the user overcomes the resistance of the elastic elements and dampers connecting the platforms. This provides the user with exercise and its accompanying benefits.

The present invention relates to a weight generation device for muscular-strength exercise, the device generating weight with vacuum pressure through the adjustment of levers and valves since adjusting weight by moving heavy weights used for exercise equipment is conventionally inconvenient. The present invention relates to the weight generation device which allows a first cylinder, that is coupled to exercise equipment so as to vertically move, to be connected to a second cylinder through an air hose, and which allows the weight generated through the adjustment of the inner volume of the first cylinder, the air hose and the second cylinder to be easily adjusted. In addition, presented is folding exercise equipment which can be applied to frames of various conventional exercise equipment, and which is applied to folding exercise equipment so as to be easily moved and stored indoors.

A liquid-resistance fitness machine has a frame body, a liquid-resistance device mounted to the frame body, and a driving device. The liquid-resistance device has a liquid tank, a shaft, and a paddle wheel set. The paddle wheel set has a hub fixed to the shaft and multiple blades. The driving device is connected to the shaft and is configured to drive the shaft to spin clockwise and counterclockwise relative to the liquid tank. A shape of each of the blades when the shaft is spinning clockwise and a shape of the blade when the shaft is spinning counterclockwise are asymmetrical to a normal line between the blade and the hub. Therefore, the liquid-resistance device can provide two different liquid resistances without changing the volume of the liquids.

An exercise machine comprises a tension generating device, the tension generating device being based on at least one of the following: electronic resistance, pneumatic cylinders, springs, weights, flexing nylon rods, elastics, pneumatics, hydraulics, and friction, a translatable arm mount coupled to the tension generating device; an arm coupled to the translatable arm mount; and a cable coupled to the tension generating device via the arm.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The apparatus allows for weight training without weights. The apparatus may provide a more effective and safer mechanism for training than conventional techniques. An aerobic apparatus using hydraulics or pneumatics for a more realistic feel is also provided. Methods of using the devices are also provided.
