A pulley rack for an exercise machine includes a support frame, an upright extending generally vertically within the support frame, a counterweight having one or more counterweight pulleys, the counterweight moveable in a vertical direction relative to the support frame, one or more guide pulleys mounted to the support frame, a cable end assembly mounted to the upright, and a pull cable having a fixed attachment end connected to the cable end assembly and a pullable end freely passing through the cable end assembly. The pull cable is routed through the cable end assembly, the counterweight pulleys, and guide pulleys such that a force exerted on the pullable end raises the counterweight. A section of the pull cable extends from the pullable end through the cable end assembly and downwardly to one of the guide pulleys mounted below the cable end assembly.

A modular exercise apparatus comprising a frame, a common drivetrain supported by the frame and including a common axle, a plurality of input receivers coupled to the common axle, and a resistance member operably coupled to the common axle and operable to provide resistance against rotation of the common axle, a first exercise attachment including a first drive member operably coupled to a first input receiver of the plurality of input receivers of the common drivetrain, and a second exercise attachment including a second drive member operably coupled to a second input receiver of the plurality of input receivers of the common drivetrain.

The invention concerns a modular exercise system having a first support frame module having a plurality of frame members, each member being joined to an adjacent frame member and oriented in a common plane such that the first support frame is two-dimensional in form. The modular exercise system further requires a weight source mounted on the first support frame, a plurality of pulleys mounted to different frame members of the first support frame, and a cable running from the weight source over the pulleys to connect the weight source to one or more manual actuator for performing a resistance exercise in use. The first support frame has one or more attachment formation for selective attachment to one or more further support frame module. The further support frame module is also two-dimensional in form and attachable to the first support frame in an orientation within the common plane, wherein the further support frame module has one or more further manual actuator.

A cable-based exercise system. A chassis is provided to house the actuators. A force plate sits on top of this chassis. A bar configured for gripping by a user is provided. The bar has a first end and a second end. Two or more cables are connected to each end of the bar. Each cable connects an end of the bar to a drive motor. Each drive motor can be independently controlled. A central processor is preferably provided to receive sensory inputs and control the drive motors.

An abdominal strengthening apparatus is provided. The apparatus comprises at least one handlebar grip, a handlebar pole coupled to the at least one handlebar grip, the handlebar pole comprising a base, wherein the base is configured to engage a first hook, a main unit body comprising a second hook and an open track channel; and an extension resistance system coupled to the first hook and the second hook. The handlebar pole is configured for a downward movement within the main unit body along the open track channel, in response to a force exerted by a user through the at least one handlebar grip. The extension resistance system is configured to facilitate an upward movement of the handlebar pole in response to release of the force exerted by the user.

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 weight training apparatus allows for weight training without weights. The weight training apparatus may provide a more effective and safer mechanism for training than conventional techniques.

Exercise equipment for weight training includes first, second, third, and fourth guide rods respectively fitted into first, second, third and fourth bearing bodies such that the first, second, third, and fourth bearing bodies slide up and down along the first, second, third, and fourth guide rods, respectively, as weights are lifted up. First and second bearings provided at each of the first, second, third, and fourth bearing bodies are arranged to crisscross each other to closely contact and support the outer surfaces of the first, second, third and fourth guide rods concurrently, thereby dispersing the load of the lifted weights, which facilitate various weight training movements by using a weight training rod, a horizontal bar, and equipment for parallel exercises.

A gym tower which includes a base and a plurality of internal weights vertically stacked on the base. A frame is connected to the base and extends upward from the base to engage with the plurality of internal weights. A top plate is connected to the frame, so that the base and the plate enclose the plurality of internal weights within the frame. The tower also includes a spine is adapted to selectively engage the plurality of internal weights. A main pulley is connected to the top plate and a main cable is fed through the main pulley. The main cable is connectable to the spine at a first end and includes a connector device at a second end. The tower also includes a rod adapted to engage with the spine and to select an internal weight and is adapted to secure to external weights.

Exercise machines for performing exercises that are resisted in the push and pull directions, the machines having at least one user support, at least one user engagement actuator, and a one directional flywheel operatively connected to a braking mechanism for providing resistance to the push and pull exercises. A drive system operatively connects the at least one user engagement actuator to the one directional flywheel, the drive system can be configured such that more or less force is required to move the at least one user engagement actuator in the push direction than to move the at least one user engagement actuator in the pull direction. The resistance of the push direction can be less than, greater than, or equal to the resistance of the pull direction. Resistance to the motion of the at least one user engagement actuator can be adjusted prior to or during operation of the machine.

A climbing exerciser includes a base mount, left and right racks located at left and right sides of the base mount respectively, two left links each having an end pivotally connected with the base mount and the other end pivotally connected with the left rack in a way that the left rack is reciprocatingly moveable up and down, two right links each having an end pivotally connected with the base mount and the other end pivotally connected with the right rack in a way that the right rack is reciprocatingly moveable up and down, and a motion linking device disposed to the base mount and linked with the left rack and the right rack in a way that the right rack lowers when the left rack raises. As such, the climbing exerciser can provide smooth and more natural movements to the user with low noise and various exercise modes.
