A cable exercise device includes a vertically movable weight stack, a rotatable spool assembly, first and second cables, and a movable exercise implement. The rotatable spool assembly is located proximate the weight stack, and comprises spaced apart large and small cable spools affixed to a common rotatable spool shaft. The first cable has a terminal end attached to the weight stack and a winding end attached to the small cable spool. The second cable has a winding end attached to the large cable spool, and extends from the large cable spool to a terminal end. The movable exercise implement is secured to the cable exercise device by the terminal end of the second cable, and is adapted for being employed by a user performing an exercise.

An exercise device for targeting the gluteus maximus muscle uses a stand to hold up a bellows pump against a vertical surface while a user repeatedly pushes the pump with a foot. The pump has a one-way inlet valve and a small restrictor opening to allow air to leave the bellows slowly, providing a mechanism for selecting different resistance values. A catch is used to keep the pump in the compressed position during storage.

A weight apparatus includes a bar including a handle rotatably attached to an anchorage. The anchorage includes a body and at least one radially extendable and retractable pin, the pin being movable relative to the body between an innermost position and an outermost position. An end of the pin extends radially beyond an external surface of the body when the pin is in the outermost position. The apparatus further includes a weight including a weight opening in which the anchorage is adapted to be received. The weight includes a radially extending pin opening adapted to receive the pin when the pin is in the outermost position to attach the weight to the anchorage. An arrangement is provided for driving the pin to the outermost position upon rotation of the handle relative to the anchorage.

The present invention relates to a base for a modular exercise system comprising: a ground element for locating the base on a surface; a resistance apparatus mounted on the ground element; an attachment means for receiving and connecting an interchangeable exercise device to the base; and at least one first sensor which is operative to detect and identify the interchangeable exercise device when connected to the base and to communicate with a processor when the resistance apparatus is engaged with a drive mechanism on the interchangeable exercise device.

An exercise device for attachment to an exercise machine includes an enclosure having an outer wall that defines an internal space therein, at least one cable aperture and an attachment mechanism for attaching to the exercise machine. A winding assembly is rotationally captured within the internal space and includes a winding spool configured for receiving at least one cable wound therearound under the urging of a coil spring. A motor is used to compress or retract a torsion spring fixed between a moving rotor plate and the winding spool for changing a cable unwind resistance. A controller circuit is electrically connected with at least a power source, a user interface, and the motor. To perform exercises with the exercise device, a person sets a desired cable unwind resistance with the user interface and then repeatedly pulls and releases the cable.

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 unweighting system includes a frame having a base and a vertical bar extending therefrom. The base is configured to connect to or at least partially encircle an exercise device. A height adjustable cantilevered arm assembly is coupled to the vertical bar at a fulcrum, and the cantilevered arm assembly is configured to receive and couple to the user. A resilient member is coupled to the cantilevered arm assembly and configured to unload a portion of the user's weight while the user is coupled to the cantilevered arm assembly and exercises on the exercise device.

A liquid buoyancy muscle training device includes a liquid receiving tank receiving and holding liquid therein. A buoyantly submergible member is buoyantly submergible in the liquid contained in the liquid receiving tank and includes a regulation chamber formed therein. A bottom pulley is mounted inside the liquid receiving tank. A rope is connected to the buoyantly submergible member and wrapped around the bottom pulley and extends upward to project outside the liquid receiving tank. A liquid regulation tank is connected through a liquid supply tube to the regulation chamber to allow liquid to flow therebetween. A gas supplier is connected through a gas supply tube to the regulation chamber to selectively supply gas into the regulation chamber to change a ratio between liquid and gas inside the regulation chamber so as to change buoyance applied to the buoyantly submergible member by the liquid contained in the liquid receiving tank.

The present invention relates to exercise equipment, particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a bench area, a guide arm, a head area, and a foot area that work in conjunction to most optimally support the user. The bench area, the head area and the foot area are all connected, supported, and elevated from the floor by a base.
