BACKGROUND OF THE INVENTION [0001]1. Field of the Invention [0002]The present invention relates to exercising apparatus and more particularly, to a simple and portable exercising apparatus that is practical for exercising the muscles of the arms and the abdomen. [0003]2. Description of the Related Art [0004]Various exercising apparatus, such as dumbbells chest developers, spring bars, and etc., are commercially available for exercising the muscles of the arms. These exercising apparatus use the designed mechanical structure for enabling the hands to make a reciprocating action, thereby exercising the muscles of the arms. [0005]When a user is operating one of the aforesaid conventional exercising apparatus, the user can only exercise the body with a fixed weight or by means of one single operation mode, i.e., the user has no choice to change the damping resistance on one same exercising apparatus. The tendons and muscles may be injured easily when exercising the body with an improper damping resistance. It is insignificant to exercise the body without safety. [0006]Further, because conventional exercising apparatus for exercising the arms are not adjustable to provide different damping resistance subject to different exercising requirements, a user may have to prepare various different weights or different exercising apparatus. There are commercially available heavy exercising machines that are adjustable to provide different exercising pressure subject to different users or subject to different exercising requirements. These heavy exercising machines, such as scissors-action machines or chest weights, are commonly expensive and require much floor space. Therefore, either using a heavy exercising machine or multiple small exercising apparatus, the user will encounter a storage problem when receiving the heavy exercising machine or the multiple small exercising apparatus. SUMMARY OF THE INVENTION [0007]The present invention has been accomplished under the circumstances in view. It is one objective of the present invention to provide a portable exercising apparatus, which is safe in use for moderate exercises and convenient for carrying and storage. [0008]It is another objective of the present invention to provide a portable exercising apparatus, which provides a damping resistance by means of compressing air when operated by the user. [0009]It is still another objective of the present invention to provide a portable exercising apparatus, which has simple structure and is inexpensive to manufacture. [0010]To achieve these objectives of the present invention, the portable exercising apparatus comprises a first frame member, a second frame member, a first tube, a second tube, an air valve, and at least one elastic member. The first tube has a first end perpendicularly and fixedly connected to the first frame member, a second end, and an opening at the second end. The second tube has a first end perpendicularly and fixedly connected to the second frame member and a second end inserted through the opening of the first tube into the inside of the first tube such that an air chamber is defined inside the first tube. The air valve is mounted in the first tube in communication with the air chamber and the atmosphere. The at least one elastic member is respectively fixedly connected between the first frame member and the second frame member. The elastically deformable material property of the at least one elastic member provides not only a resisting force to the user when the user is operating the exercising apparatus but also a rebounding force to return the two tubes to the former position during operation of the exercising apparatus. [0011]According to the present invention, the air contained in the air chamber is compressed to impart a damping resistance when the user moves the first frame member and the second frame member toward each other. By means of adjusting the air valve to regulate the air discharging speed, the damping force is relatively adjusted. Therefore, the user can adjust the air valve to further adjust the damping force as desired. [0012]The user can operate the exercising apparatus in any of a variety of operation modes to exercise the muscles of the arms. In additional to exercising the muscles of the arms, the exercising apparatus can also be operated to exercise the muscles of the abdomen.
