A multi-functional curved board to be used when working in standing position and for working when sitting down as a support for feet and generally for maintaining muscle strength, the multi-functional curved board having at least one curved body (1). The body (1) comprises at least one counter-curve means (3). One surface (1b) of the body is curved outwards and the counter-curve means are fastened to a surface (1a) opposite this surface (1a) adjacent the end sides (1d) of the body (1) and the counter-curve means are curved outwards from the opposite surface of the body (1).

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.

A method for use with a physical training device is provided. The device including an elastic resistance strap having first and second handles. The method includes pulling at least one of the first and second handles to generate force on a target muscle group through resistance training. The method also includes pulling the at least one of the first and second handles to generate anaerobic and aerobic muscle activity within the target muscle group through cardiovascular interval training.

A layered strap-like apparatus for exercising, stretching and training multiple muscle groups of the entire body of a user. The apparatus is adapted to be worn about the waist or carried as a bandolier about the user's body. The apparatus has an optional, releasably closable pocket between the layers for securing and carrying accessories, such as attachable handles and elastic bands. The apparatus and methods of use provide the user with balanced loading options and the flexibility to exercise anywhere.

A machine for concurrently or independently performing pressing motions with the hands and feet, the machine having a base having front and back ends, two or more linear slide rails, a lower body user support with an engagement means for the user's feet and an upper body user support with an engagement means for the user's hands. The upper body user support and lower body user support slide on the linear rails that are located proximally on opposing ends of the base frame and the upper body user supports and the lower body user supports cooperate with one another to move in opposing converging and diverging sloping linear movement patterns during operation of the machine.

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.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

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.

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 exercise apparatus includes an elongate cable being elastic and having opposing first and second ends configured to be grasped by a user. The elongate cable is configured to provide resistance to being stretched along its length in response to an application of a tension force to the first and second ends of the cable and return to its unstretched length upon the user releasing the tension force. The elongate cable includes a first portion having a first elasticity, and a second portion having a second elasticity that is different than the first elasticity of the first portion.
