This invention is directed toward an exercise band that is circular in shape, defining a central cavity with a diameter sufficient to allow average people to insert their legs into the cavity, and push in an outward direction to exercise the gluteus muscle groups. The exercise band has an inner core of a resiliently stretchable material, and an outer cover made from a material that is easily washed, to remove the sweat of the user. The connection of the two ends of the invention is accomplished through a three-fold sew-based connection. The band provides a simple, small, easily transported and stored exercise device for standing, sitting, squatting and prone exercises. Several of these bands, each with a different degree of resistance, can be combined in a set, allowing people to work up to ever-increasingly more resistant bands without having to adapt to a new shape of band.

An interactive exercise system with apparatus and methods to optimize muscle strength for rehabilitation, to improve or maintain fitness, and to enhance the performance of athletes. The system uses an electronically controlled linear actuator to generate resistance against the muscular force exerted by the user. The system includes sensors configured to detect acceleration, speed, velocity, position, direction of movement, duration, and the force applied by the user. A control system preferably continuously monitors the sensors, and instantaneously adjusts the adaptive actuator. This provides a proportional counterforce to the user force throughout the entire range-of-motion. A display panel allows the user to interact with the system in real-time. The objective of the user is to synchronize the exercise performance with a selected target goal, by correlating the user's movement relative to a position on a display panel.

A muscle stretching device. A first base and a second base each include a foot adjustment portion and a connector portion. The connector portion of the first base is coupled to the connector portion of the second base. The connector portions are adjustable to adjust a distance between the foot adjustment portions. A right foot support is pivotally coupled to the foot adjustment portion of the first base and is rotatable relative to the first base about a first vertical axis. A left foot support is pivotally coupled to the foot adjustment portion of the second base and is rotatable relative to the second base about a second vertical axis.

A balance board fitness training device is provided. The fitness training device may include a deck having a top surface, a bottom surface, and opposing first and second side edges and opposing front and rear longitudinal edges together forming a perimeter of the deck; at least one wheel bracket structure positioned below the deck, the at least one wheel bracket structure rotatably supporting at least two wheels and configured so as to be movable relative to the deck about a pivot line at least partially extending between the opposing first and second side edges of the deck; and at least one resilient member connected to the at least one wheel bracket structure and the deck.

A stretching machine of two seat having bases and backrests which is pivotally mounted to the base including a first leg platform having a pivot end and a free end, the pivot end being connected to the base of the seat and a second leg platform having a pivot end and a free end, the pivot end being connected to the base of the seat. The stretching machine includes a mechanism for rotating the backrest relative to the seat as well as a mechanism for rotating the leg platforms about their respective pivot ends such that the free ends move in a generally arcuate path.

An exerciser has a baseplate with a fulcrum projecting outwardly from one side and wheels depending outwardly from the opposite side. A balanced-enhanced exercising platform is provided when the fulcrum is positioned downwardly on a floor, and alternatively, a balance-enhanced exercising dolly is provided when the wheels are positioned downwardly on the floor. The dolly may be biased by elastic resistance straps.

The exercise equipment includes a base, a resilient element, and a positioning mechanism. The base has two bodies which are selectively movable relatively. The two sides of the resilient element are connected to the two bodies. The positioning mechanism is adapted for operation to control the movement of the two bodies.

A fitness apparatus and a method for assembly are disclosed. The fitness apparatus comprises a wheel assembly that includes a first circular side parallel to a second circular side, both bounded by a curved tread. Within the wheel assembly is an enclosable storage chamber. The fitness apparatus also includes an axis perpendicular to the first circular side and the second circular side, and when the fitness apparatus is in an abdominal exercise wheel configuration, at least a portion of the wheel assembly rotates around the axis. The fitness apparatus also includes a centerbore along the axis that supports a first removable handle and a second removable handle when the fitness apparatus is in the abdominal exercise wheel configuration.

A passive muscle training device includes a base having at least one first link and at least one second link. At least one first rod is pivotably connected to the at least one first link. At least one second rod is pivotably connected to the at least one second link. The at least one first rod and the at least one second rod each have a handle extending beyond the cover on the base. A power input end is pivotably connected to the first rod and drives an eccentric portion of a shaft to swing the at least first rod and the at least one second rod alternatively. The user holds the two handles and the user's muscles are trained by centripetal contraction and centrifugal contraction due to the movement of the handles.
