       FIELD OF THE INVENTION  
       [0007] The invention herein relates to an exercise device, especially relates to a multifunction aerobic exercise device.  
       BACKGROUND OF THE INVENTION  
       [0008] There are more and more people interested in kung-fu. Mostly, they do such exercise by nunchaku. Nunchaku is a well-known martial arts training device and weapon. Typical nunchaku consists of two hardwood handles coupled with a short length of chain or cord at their ends. In FIG. 1A, it illustrates a traditional nunchaku  10 , which comprises a pair of rigid handles  11  and a connecting chain  12 . During combat, one handle normally is held in one hand while the other free handle is swung at the opponent or warded off the opponent&#39;s attacking. During practice or prior to combat, for physiological reasons and to confuse the opponent, one handle is held in one hand while the other, free handle is swung over the shoulder, under the arm, under the leg and around the waist of the person using the nunchaku  10 . Thus, it is necessary to have a safer nunchaku for combating or practicing. Besides, the connecting portions  111  of the solid handles  11 , as shown in the FIG. 1A, are connected firmly by connecting posts. Therefore, it may cause the connecting chain  12  broken when whirling the nunchaku  10  forcefully. The solid handles  11  are typically made by rigid hardwood, plastic, or other similar material, so it may be easy to get hurt when combating or practicing improperly. Particularly, if there are children or teenagers trying to use a nunchaku, it is important to have a safer device. Moreover, none of these nunchakus has elastic rope to allow the nunchaku has additional function such as aerobic exercise.  
       [0009] Furthermore, if there is no opponent for practicing or combating, it is desirable to gain another advantage when using a multifunction nunchaka, for example, to be use as an aerobic exercise device for Cardio Kick-Boxing or Tae-Bo.  
       SUMMERY OF THE INVENTION  
       [0010] The invention herein provides an aerobic exercise device comprising a pair of rubber holding rods having a receiving hole respectively, a pair of spheroidal revolvers located in said receiving holes respectively, and at least an elastic rope made by latex material being coupled with said revolvers by two ends thereof.  
     
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
     [0011] The present invention will be better understood from the following detailed description of preferred embodiments of the invention, taken in conjunction with the accompanying drawings, in which  
     [0012]FIG. 1 is a perspective view of a traditional nunchaku;  
     [0013]FIGS. 2A and 2B shows perspective views of an aerobic exercise device assembly in accordance with the present invention; and  
     [0014]FIG. 3A and FIG. 3B show picture of embodiment examples for how to use the present invention. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0015] The following descriptions of the preferred embodiments are provided to understand the features of the present invention.  
     [0016] The FIG. 2A illustrates a perspective view of an aerobic exercise device assembly  20  in accordance with this invention, which comprises a pair of rubber holding rods  21  having a receiving hole  211  respectively, a pair of spheroidal revolvers  22  located in said receiving holes  211  respectively, and elastic ropes  23  made by latex material being coupled with said revolvers by their ends. In this embodiment example, the ends of elastic ropes are put into holes of the spheroidal revolvers  22  and tied tightly therein, or connected by glue. Besides, the spheroidal revolvers  22  are made by inflexible material as a universal joint, so the elastic ropes  23  may be not easy to break. In addition, it is easier and cheaper for manufacture.  
     [0017] Referring to the FIG. 2B, which illustrates the perspective view of this invention. Particularly, the rubber holding rods  21  are designed for holding easily, and the elastic ropes  23  are another feature for extending. Moreover, the material of said holding rods  21  and said elastic rope  23  are safe for combating or practicing. Therefore, this invention may be a nunchaku replacement for kids, it is much safer.  
     [0018] Furthermore, if there is no opponent for practicing or combating, it is desirable to gain another advantage when using a multifunction nunchaka, for example, to be use as an aerobic exercise device for Cardio Kick-Boxing or Tae-Bo. Please referring to the FIGS. 3A and 3B, the present invention may be not only using as a nunchaku, but also an aerobic exercise device.  
     [0019] The present invention may be embodied in other specific forms without departing from the spirit of the essential attributes thereof; therefore, the illustrated embodiment should be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
