CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority benefit of Korean Patent Application No. 20-2005-0000021 filed Jan. 3, 2005, the technical disclosure of which is hereby incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a bench press used to strengthen the chest and arm muscles, and more particularly to a bench press in which a user can control the increase and decrease of weight without assistance, so as to achieve maximal physical effect, and which allows one to safely exercise. [0004] 2. Description of the Related Art [0005] A bench press is a type of sports equipment, which is used to strengthen the chest and arm muscles. The bench press is operated by lying on a bench, positioning the arms at predetermined intervals, so as to grasp a barbell supported on supports, and then raising and lowering the barbell repeatedly. [0006] In conventional bench presses, if the user is unable to support the barbell due to exhaustion, resulting from extended lowering and raising of the barbell, injury to the face, chest, or neck frequently occurs, as the user is unable to return the barbell to the supports and drops the barbell. [0007] As a bench press designed to prevent injury, a bench press in which a protector is provided on a bench to prevent the barbell from being dropped on the face, neck, or chest, is disclosed in U.S. Pat. No. 5,217,421. [0008] Additionally, U.S. Pat. No. 4,253,662 discloses a bench press in which a barbell is suspended from one end of a rope or a chain, the weight is suspended from the other end of the rope or chain, and a clutch is disposed at the intermediate portion of the rope or the chain such that the user manipulates the clutch to stop the movement of the rope or the chain. [0009] However, according to the above conventional bench presses, though injury to the user can be prevented, the exercise effect cannot be enhanced without assistance. [0010] In order to strengthen the muscles using the bench press, contraction and relaxation of the muscles must be repeated a certain number of times. Particularly, in order to strengthen the muscles with maximum effectiveness, it is preferable to change the weights during the repetition of contracting and relaxing the muscles. Thus, assistance is required to adjust the weight applied to the barbell when the user exercises to strengthen the muscles using the conventional bench presses. [0011] However, since assistance is not always available, the conventional bench press is deficient in its ability to maximize exercise effects. SUMMARY OF THE INVENTION [0012] Therefore, the present invention has been made in view of the above and/or other problems, and it is an object of the present invention to provide a bench press that a user can adjust the weight of a barbell without assistance so as to achieve effective exercise and to prevent accidents. [0013] In accordance with the present invention, the above and other objects can be accomplished by the provision of a bench press for strengthening chest and arm muscles, including a frame including a bench on which a user lies and a support for supporting a barbell, a first cable having an end that is connected to the barbell and suspending the barbell through a first pulley rotatably installed in the frame, a second pulley, to which the other end of the first cable is connected, rotatably installed in the frame, a cam-shaped pulley rotated together with the second pulley, a second cable having an end connected to the cam-shaped pulley, and a foothold, to which the other end of the second cable is connected, provided in the frame so that the user moves the foothold to pull the second cable. [0014] In the bench press claimed in claim 2, the foothold includes a guide member installed in the frame at an angle, a sliding member slid along the guide member by the user, and a spring for maintaining the tension of the second cable when the second cable is pulled by the sliding member to which the other end of the second cable is connected. [0015] In the bench press claimed in claim 3, the guide member of the foothold comprises a stopper for restricting the movement of the sliding member and for preventing the barbell connected to the sliding member from being fallen on the user. [0016] In the bench press claimed in claim 4, the height and tilt angle of the bench are freely adjustable. BRIEF DESCRIPTION OF THE DRAWINGS [0017] These and/or other objects and advantages of the present invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings, in which: [0018] FIG. 1 is a perspective view illustrating a bench press according to the preferred embodiment of the present invention; and [0019] FIG. 2 is a side view illustrating the bench press according to the preferred embodiment of the present invention.
