A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

An exercise bar assembly includes a pair of rotating grip assemblies, each including a generally planar frame and a hand grip mounted within the frame for rotation within in the plane of the frame. The rotating grip assemblies are attachable to opposite ends of a center bar assembly along the longitudinal axis of the bar assembly. A plate bar assembly is attachable to each of the rotating grip assemblies opposite the center rod, with the plate bar assembly aligned with the longitudinal axis to form a weight lifting bar. A user-selectable elastic band is engageable between the pair of rotating grip assemblies along the longitudinal axis so that the elastic band resists rotation of each hand grip in each of the rotating grip assemblies. The rotating grip assemblies of the exercise bar assembly allow for the full range of motion of the bicep, and the elastic band creates a resistance exercise through the bicep's full range of motion.

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.

Apparatus (60) for supporting a subject (2) in an inverted state comprises a ground engaging plinth (8) and a support platform (12) pivotally coupled to the plinth (8) about a first pivot axis (15) so that the support platform (12) is pivotal between a first state with a subject (2) in a supine state on the support platform (12) and a second state with the subject (2) inverted on the support platform (12). The subject is supported in the inverted state on the support platform (12) by shoulder engaging elements (24), and is secured to the support platform (12) by a torso strap (35). A foot engageable element (77) connected to a weight carrying bar (84) through connecting members (79,82) extending through an elongated slot (80) in the support platform (12) allows leg and abdominal muscles to be exercised by urging the foot engageable element (77) in the direction of the arrow A against weights (85) carried on the weight carrying bar (84). A carrier element (81) slideable on a guide bar (83) guides the foot engageable element (77). Handgrips (86) are connected by steel cables (87) around pulleys (88,89,90,91) to the weight carrying bar (84) for facilitating exercising of arm, shoulder, chest and back muscles.

Exemplary embodiments of a portable exercise apparatus are provided, the exercise apparatus including a base, a bottom plate secured to a top portion of the base, a bracket affixed to the bottom plate, a base plate secured to a top portion of the bottom plate, the base plate including a plurality of holes on a top surface of the base plate, a foot plate secured to a top portion of the base plate and configured to selectively engage with at least one of the plurality of holes on the top surface of the base plate, such that when the foot plate is rotated the base plate and bottom plate also rotate, a threaded hole on the base, and a first resistance element having a first end secured to the threaded hole on the base and a second end secured to the bottom plate.

An ankle exercise device comprises a base frame, a heel rest, a rotational component, and a plurality of resistance bands. The resistance bands may be connected to the rotational component. The rotational component rotates 90 degrees to orient the resistance bands in either a horizontal or vertical direction. The heel rest may comprise a u-shaped cutout to cup a user's heel. The heel rest is adjustable to align the heads of a user's metatarsals between the resistance bands. With the resistance bands in the horizontal direction, the user may rotate the ankle in the plantarflexion and dorsiflexion directions. With the resistance bands in the vertical direction, the user may rotate the ankle in the inversion and eversion directions.

The present invention relates an exercising system. The exercising system is a geodesic dome structure coupled with an exercise device such as a flywheel. The geodesic dome is made up of multiple struts coupled to each other at multiple hubs. The exercise device is engaged with the hub to allow a user to exercise through the flywheel.

A device and method may be provided including at least one handle and at least one anchor point. The device may be operable to provide a resistance to a user of the device who fixes the device using the anchor point and pulls on the handle. The device may include a casing; a center rod rotatable mounted in the casing; a cable wound around the center rod and coupled to the handle; and a mechanism mounted on the central rod. The mechanism may be responsive with a centrifugal force to movement of the cable to rotate the central rod. The mechanism may include an anchor coupled to the central rod, and at least one weight connected by a wire to a ring that is movable along the central rod against the resistance of a spring.

A constant resistance exercise machine for sprint training or adaptation into exercise equipment having cyclical movements, preferably over a distance. The constant resistance exercise machine includes an exercise cable storage and feed reel, a constant tension spring motor, a resistance generating assembly, a flywheel, and an exercise cable. The constant tension spring motor is in operational communication with the exercise cable reel. The flywheel obtains a rotational resistance from the resistance generating assembly. The flywheel is in unidirectional rotational communication with the exercise cable reel via a one-way clutch bearing. The exercise cable is coiled about the exercise cable reel. The exercise cable is of a length that enables complete extraction of the cable from the exercise cable storage and feed reel and wherein the constant tension spring motor is arranged to retract a partially or completely extracted cable back onto the exercise cable reel.

An exercise device is described. An exercise device including a body, the body having a top, a bottom, a first end located at one edge of the body, a second end located at an opposite end of the body, and first and second sides extending between the first and second ends; one or more wheels; and an energy storage device applying resistive and restoring force to the wheel. Optionally, a shaft can be present that rotationally locks two or more of the wheels.
