<p>An exercise apparatus comprises a plane formed by two elongated parts include a pivotal joint arrangement for accomplishing an angle between the parts of the lane. The plane of two parts comprises at the lower part thereof a stationary joint arrangement, which is arranged to be fixed substantially above the horizontal base. Locking devices are provided for locking the plane of two parts into erected vertical position. Adjustable supports are provided for supporting the plane of two parts to form an inclined plane between the stationary joint arrangement of the plane of two parts and the base and for supporting the plane to form an angular plane. The angular plane includes the first elongated part between the stationary joint arrangement and the joint arrangement of the plane of two parts in substantially horizontal position and the second elongated part between the joint arrangement of the plane and the base in substantially vertical position.</p> |
