TECHNICAL FIELD [0001] The present invention relates to an apparatus for three-dimensional anaerobic exercise capable of attaining stability in three-dimensional motion trajectories necessary for the human body, and more particularly, to an apparatus for three-dimensional anaerobic exercise, which applies a reduction linkage concept, but not a four-rod linkage concept disclosed in Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712, previously filed by the inventor of the present invention, for safe three-dimensional motion trajectories in approach to each of various regions of the human body, thereby increasing durability, reducing manufacturing costs, and realizing motion trajectories of various kinds, which are merits of the three-dimensional exercise. [0002] In addition, the present invention relates to an apparatus for three-dimensional anaerobic exercise, which can provide a new approaching method for overcoming lots of limitations of Korean Patent Applications, filed on May 17, 2002 and May 27, 2002 by the inventor of the present invention, in basic configurations such as a rocking angle range of ball joints, and an angular motion range of a handle, and a form change of a horizontal trajectory of a linkage. BACKGROUND ART [0003] As shown in FIGS. 7, 9a and 9b of U.S. Pat. No. 5,769,757, exercise using the reduction linkage concept imposes burden on an exerciser's wrists, forearms and shoulders and involves a danger of injury when an angular motion of the handle is simply applied to the human body since an angle of the handle is subject to the angular motion of a reduction linkage. As a result, the exercise using the reduction linkage concept cannot attain safety and variety, which are characteristics of the three-dimensional motion trajectory. [0004] Disadvantages of the exercise using the reduction linkage concept will be described in more detail as follows. Since a handle shaft and the lower end of the handle are connected directly with each other and rectangular in an "L" shape, the angle of the handle is influenced by the angular motion of a handle linkage. So, as shown in FIG. 9b, angles g and g' are formed at a start point and an end point of the motion, and thereby, the handle is not rectangular to the movement direction of the human body as shown in FIGS. 8a and 8b of the application previously filed by the inventor of the present invention, and in drawings of U.S. Pat. Nos. 5,997,447, 5,989,165 and 6,071,216. [0005] Therefore, it is difficult that the prior arts provide a safely three-dimensional exercise as imposing burden on the exerciser's wrists, forearms and shoulders. The reason is that movement of the third linkage of the four-rod linkage is not greatly influenced by the angular motion of the first and second linkages, but the angular motion in the reduction linkage concept is transferred to the angle of the handle as it is. [0006] In more detail, the three-dimensional exercise of the reduction linkage concept has a limitation in realistic approach, but can be applied to a rehabilitation program for a predetermined movement area of the human body since the handle is idly rotated on a bearing as shown in FIG. 13. [0007] The origin of the term "the initial load machine of Japan Tottori-ken" of Japanese Patent (shown in FIG. 13) resides in the fact that a movement range is applied only to an initial primary section (I) when the movement range is divided into three as shown in FIG. 14: an initial section (I), a middle section (II), and a final section (III). [0008] In the exercise using the reduction linkage concept, in view of the structure of the handle without regard to characteristics of the angular motion of the linkage, the primary load machine of Japanese Patent, which provides an idle rotation, is realistic rather than U.S. Pat. No. 5,769,757 and can provide a safe exercise in spite of the movement within a restricted section. [0009] The L-shaped handle where the handle shaft and the end of the handle are directly connected to each other as shown in FIG. 7 realizes convex motion trajectories from the human body as shown in FIGS. 9a and 9b, and so, cannot realize concave motion trajectories necessary for the human body. The convex trajectories are one of characteristics of the typical angular motion of the handle when the end of the handle is directly connected to the handle shaft. As shown in FIG. 4, as a side of the handle must be directly connected to the handle shaft to obtain the concave trajectories, which are most of the three-dimensional motion trajectories of the human body, the L-shaped handle shows a limitation in realizing the three-dimensional motion trajectories of the human body. As disclosed in U.S. Pat. Nos. 5,967,954, 5,562,577, 5,997,447, and 5,582,564, recently, a great deal of studies and attempts have been made to develop exercise devices for realizing motion trajectories necessary for the human body and safe and stable angle of the handle. [0010] As shown in FIG. 10, the prior art has limitations in realizing a twist angle of 60 to 120 degrees required by the human body due to the rocking angle (40.about.50 degrees) of a restricted ball joint since the ball joint is mounted in a horizontal direction from an auxiliary linkage. [0011] That is, as shown in FIGS. 2 and 6, as the ball joint has a restricted rocking angle (40.about.50 degrees) in a vertical direction where a circular motion is carried out, the ball joint can secure the angular motion only by axial mounting suitable for the direction of the angular motion. [0012] Furthermore, as shown in FIG. 7, a handle side lever for the angular motion is not mounted integrally with the handle, but must be mounted opposite to the handle from a bearing housing. [0013] As shown in FIG. 11, if the handle side lever is mounted opposite to a handle frame from a bearing box, a ball joint connection point located at the lower end portion of the auxiliary linkage must be moved to a position lower than a shaft of a handle linkage to obtain a proper angle of the handle. [0014] In this case, since the length of the handle linkage must be shortened or the auxiliary linkage must be enlarged, considering that the human body is 160.about.19 cm in height and 45.about.80 cm in arm length, the handle linkage performs lots of angular motions (V, V') as a basic motion trajectory as the exercise device is enlarged or the handle linkage is shortened, and so, the human body may show rejection symptoms. [0015] Particularly, if the auxiliary linkage is larger than the handle linkage as shown in FIG. 12a, in a section x, an angular motion distance y of the handle is successively increased, but if the auxiliary linkage is shortened as shown in FIG. 12b, the angular motion distance y is successively decreased, so that the length of the auxiliary linkage may have an influence on the three-dimensional motion trajectories of the human body and the form of the convex or concave motion trajectories in view of a plane as shown in FIG. 5. [0016] Therefore, the length of the auxiliary linkage must be similar to or shorter than that of the handle linkage to set an even or proportional angular momentum of the handle and to realize stable motion trajectories. If the auxiliary linkage is longer than the handle linkage, as the angular motion of the handle is rapidly increased and a movement range (a) is varied according to a figure of the human body, it is difficult to provide proper motion trajectories. The auxiliary linkage and the handle linkage must not be influenced by any factors excepting a distance (d) between the handle linkage and the auxiliary linkage. [0017] As shown in FIGS. 17 to 21, a handle side lever must closely approach the auxiliary linkage in the case where a cross joint is used, which is one of components of the present invention. Otherwise, since the auxiliary linkage must be longer and the position of the lower side lever must be lowered, the lower lever of the cross joint has a complicated structure and there are lots of restrictions in applying angular motion displacement by section. [0018] Moreover, the realization of the motion trajectories for three-dimensional exercise of the prior art have no efficiency because there is no device for various motion trajectories, which are the most greatest merits of the three-dimensional exercise, such as a handle frame A and a handle frame B, which will be described in the present invention later, and there is no means for axially fixing the handle shaft at a proper angle. [0019] That is, U.S. Pat. No. 5,769,757 is nothing but a simply mechanical approach regardless of the tree-dimensional movement of the human body. [0020] The reduction linkage needs several basic elements for realizing the safe three-dimensional motion trajectories of the handle like the four-rod linkage. [0021] First, as shown in FIGS. 3 and 4, when the handle forms predetermined motion trajectories while carrying out the angular motion, an angle of the handle must be made perpendicularly to the power direction of the human body or according to demands of the human body. [0022] Second, for improved three-dimensional exercise of target muscle of the upper part or the lower part of the human body, as shown in FIG. 2, since a basic motion trajectory for two arms movement must be not horizontal but trapezoidal, the other end of the handle linkage with an angle .alpha. or .alpha.' must perform a trapezoidal movement in view of a plane.
