There is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.

An exercise machine with adjustable platforms for adjusting the angular orientation of one or more end platforms and/or carriage platform to allow for a wide range of exercise moves. The exercise machine includes a rail to which a carriage is movably connected and a first end platform connected to an end of the rail. The carriage includes a platform which may be adjusted between a level position in which the platform is laid flat and a raised position in which the platform is at an angular incline. The first end platform may similarly and independently be adjustable between the level position in which the first end platform is laid flat and a raised position in which the first end platform is at an angular incline. In some embodiments, the exercise machine may include a second end platform which is similarly adjustable between a level position and a raised position.

The present invention is directed to a multiply convertible bicycle exercise apparatus, and intends to provide a multiply convertible bicycle exercise apparatus that allows the form of a bicycle exercise apparatus to be freely converted into various forms such as standing, sitting, dancing, and riding forms, so that various types of exercise can be enjoyed, various types of exercise apparatuses can be replaced with a single exercise apparatus, and the shape and size of the exercise apparatus can be adjusted to fit the physical size of a user even in a converted state, and that changes the location of the center of gravity of the bicycle exercise apparatus from the existing lower portion to the upper portion where a user's groin is located, so that the bicycle exercise apparatus is stable in connection with the center of gravity and is superior in terms of stability.

An exercise apparatus for assisting a user with a range of exercises includes a frame having a first frame section extending in a generally horizontal direction. At least one carriage is configured to support a user, wherein the carriage is slidably supported on the first frame section. A first resistance system has a first resilient member removably connected to at least one of the carriage and/or the frame. The displacement of the carriage relative to the frame exerts a tensile force on the resilient member. A second resistance system includes a load moveably mounted with respect to the frame and an actuation member connected to the load. The actuation member is configured to displace the load when a force exerted by the user on the actuating member exceeds a predetermined threshold representative of the load.

An exercise or fitness device designed to strengthen the entire body, with particular focus on the upper body. The device facilitates the strengthening of the core, chest, back, shoulder, and arm muscles, and in particular those muscles that move the core in the transverse plane. The device consists of two hemispherical shells, both of which have handles attached via risers. This arrangement allows the device to be gripped either by the spherical surfaces, by the handles, or a combination thereof. The two hemispheres are attached to each other by means of a shaft with a variable braking mechanism. The braking mechanism can provide levels of rotational resistance from almost zero to virtually impossible to rotate, with the resistance level being visibly indicated on the exterior of the device. The resistance level is changed by repeatedly rotating the two halves against each other in one direction or another. Key areas of the exterior of the device are treated with non-slip areas to facilitate the user gripping the device during exercise.

A multipurpose exercise device for replicating exercise motions that has a base on a support surface and a user platform. One end of a support post is axially mounted to the base and the other end is pivotally mounted to the user platform. The platform pivots with the post in a horizontal plane parallel to the support surface and pivots in a vertical plane perpendicular to the support surface. Resistance elements, dampening elements and a linkage system are selectively mounted to the support post and the base to control the velocity and angle of pivot of the platform in the horizontal and vertical plane. Ski and snowboard modules may be mounted to the user platform. The user stands on the platform or modules and performs exercise motions to propel the platform in the horizontal plane and the vertical plane to replicate the exercise motions, e.g., skiing and snowboarding.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

An end platform for an exercise machine for increased support of an exerciser's spine, neck and head which allows for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform. The end platform for an exercise machine generally includes a novel, ergonomically improved stationary platform affixed to at least one opposed end of a substantially longitudinal exercise machine that includes at least a resistance biased reciprocating platform. The improved end platform provides for increased support of exercisers' spine, neck and head, thereby allowing for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform, and further provides for the attachment of new and novel exercise equipment accessories to the exercise machine.
