An exercise device for allowing multiple exercise movements is provided. The device includes a substantially cube-shaped frame, and a unit for doing exercise movements on at least one side of the frame.

An exercise device including a body engagement portion that can support a user, and a guide track assembly that can rotationally house the body engagement portion. The body engagement portion includes a base surface and a rotation support assembly. The base surface may support the user in a standard plank position. The body engagement portion may allow a user to rotate between a first side plank position, the standard plank position, and a second side plank position relative to a support surface while the guide track assembly remain in contact with the support surface and the body engagement portion support upper body of the user. The body engagement portion may allow a user to statically hold a plank position or rotate between two plank positions at any angle equal to, or between, the first side plank position, the standard plank position, and the second side plank position.

A novel rowing machine attachment includes a bracket for attaching to a roller assembly of a rowing machine and a receiver for attaching to a handle of a rowing machine. In a particular embodiment, the bracket fixably attaches to the roller assembly and the receiver releasably attaches to the bracket for selective use. In a more particular embodiment, the bracket and the receiver are both integral parts of a single rigid body structure.

A rebounding device includes a front member, a rear member, and a spring mechanism including a first biasing element and force adjustment assembly. The force adjustment assembly includes a spring element including a front planar surface and a rear planar surface connected at a rounded portion, wherein the front planar surface contacts an inner surface of the front member; a screw housing secured to an inner surface of the rear member, wherein the screw housing includes a longitudinal channel and a bore on an upper surface; a drive screw positioned through the bore and along the longitudinal channel of the screw housing; a threaded block positioned within the longitudinal channel of the screw housing, wherein the threaded block is configured to move vertically along the longitudinal channel, and wherein the rear planar surface of the spring element is secured to the threaded block.

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.

A parallel bar stand assistance device is provided. The parallel bar stand assistance device includes a first bar and a second bar that are placed in a vertical configuration. The first bar and the second bar are in a parallel alignment with each other. A first arm support is placed on the top end of the first bar, while a second arm support is placed on the top end of the second bar. A first leg support is slidable and is placed on the inner face of the first bar. A second leg support is slidable and is placed on the inner face of the second bar.

In one example, an exercise apparatus comprises: a shaft; a roller wheel mounted on and rotatable around the shaft; a first pair of gripping members formed on two opposite ends of the shaft; a second pair of gripping members, each of the second pair of gripping members being formed on the shaft between one of the first pair of gripping members and the roller wheel; and a wall-mounting device connected to the shaft, the wall-mounting device being configured to be mounted on a wall above a top portion of a door frame to suspend the second pair of gripping members and the roller wheel in a space below the top portion of the door frame while the first pair of gripping members is in contact with two side portions of the door frame.

An exercise machine with multiple contact surfaces for providing secondary exercise support platforms positioned at various planes relative to the horizontal plane of the primary exercising platforms, the secondary platforms further serving as handles used during the performance of exercises. The exercise machine with multiple contact surfaces generally includes a frame, a carriage movably attached to the rail, and a first support structure and a second support structure attached to the frame near the first end. The support structures each include one or more platforms having an upper surface that is positioned above the base plane of the carriage.

An exercise apparatus for performing one or more exercises is described. The exercise includes at least one support structure, one or more elastic bands, and a back support member. The one or more elastic bands is coupled to the at least one support structure at one end of the one or more elastic bands. The back support member is arranged in an inclined position such that a first end of the back support member is detachably coupled to the at least one support structure and a second end of the back support member is supported at a surface positioned at a height lower than a height at which the first end is positioned. The one or more elastic bands are configured to assist a user during one or more exercises, where the back support member configured to support a body of the user.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.
