A plank support exercise apparatus and related methods is provided. The plank support exercise apparatus has a hand grip and a frame extending from the hand grip. At least one arm support pad is connected to the frame, wherein a distance between the hand grip and the at least one arm support pad is adjustable. A ground-interface surface is positioned along at least a portion of the frame.

An abdominal twist exercise device includes a device frame, front and rear rotational axles, a main handle bar, a rotation converter, an adjustable gear, a disengaging lever, a weight, a weight bar, a support rail, a safety handle bar, rotation counters, and a user platform, such that when the main handle bar rotates to one side, the user platform rotates to an opposing side. A rotation converter can include a front chain sprocket, an intermediate rotational axle, an intermediate chain sprocket, a roller chain, an intermediate gear, a rear gear; or a front belt sprocket, a rear belt sprocket, and a twisted belt, connecting the sprockets. Optionally, the front and rear axles can be telescoping.

The present invention relates to a multi-functional exercise apparatus, and particularly to a multi-functional exercise apparatus which is safe and allows various exercises with different setups to be performed by means of a single apparatus. The present invention, relating to a multi-functional exercise apparatus provided so as to impart a sense of stability to a user when exercising while at the same time allowing various exercises with different setups to be performed by means of a single apparatus, comprises: a plate-shaped body (A) forming the floor surface and having a space in the interior thereof; fixed frames (100) fixedly disposed upwardly on both sides of the body (A); rotatable frames disposed upwardly on both sides of the body (A); handle parts (200) connected on one side of the rotatable frames and provided so as to be movable forwards and backwards; and a foot plate part rotatably provided on upper surface of the body (A) and connected to the other side of the rotatable frames. The multi-functional exercise apparatus according to the present invention imparts a sense of stability to a user as the rotatable frame comprises a plurality of linked sections and connects the handle parts and foot plate part, allowing the user to exercise by rotating not the entire rotatable frames but only the handle parts which are comparatively short compared to the rotatable frames. Furthermore, each linked section of the rotatable frames is rotatably attached to the handle part or to the side of the fixed frame, allowing the rotatable frames to stably transmit driving power from the handle parts (200) to the foot plate part and to be changed so as to allow various exercises with different setups to be performed.

An exercise machine includes a frame for resting on the ground, and a footboard element which oscillates with respect to the frame about a first axis and a second axis which are mutually perpendicular.

The exercise machine further includes a handgrip element which oscillates with respect to the frame in an oscillating manner about a first axis and a third axis which are mutually perpendicular.

The footboard element and the handgrip element are functionally connected to each other in order to move in a substantially synchronous manner during the respective oscillation.

In one or more embodiments, one or more systems, methods, and/or processes may provide first images to a user; determine a rotation of a head of the user; provide second images, based at least on the rotation, to the user; and rotate a platform in accordance with the rotation. In one example, the platform may include a movement belt, and one or more of a walking movement and a running movement of the user may be determine via the movement belt. In another example, one or more optical sensors may be utilized to determine movements of the user. In one or more embodiments, determining the rotation of the head of the user may include utilizing one or more of a gyroscope and an accelerometer of a head mounted display, worn by the user. For example, the head mounted display may provide images of a virtual reality environment to the user.

An active exercise and therapeutic system for promoting physical motion, balance and coordination and importantly a variety of therapeutic modalities to a user's foot or feet. The system includes a training apparatus having a stationary base member operatively interconnected with first and second rotating platforms mounted thereon. The first and second rotating platforms are adapted to receive, respectively, the foot of an individual to stand thereon such that each foot can rotate independently about a separate axis. Stationary base member with rotating platforms mounted thereon can further be positioned upon a specialized mount operative to impart a further range of motion or specific orientation. In further embodiments, the rotating platforms may be provided with a variety of functional modalities, such as calorie counting, distance travelled, and the like, or a therapeutic modality, such as heat, cold or pressure sensation to impart a therapeutic effect to the user's feet.
