BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exerciser, and more particularly to an upper and lower body exerciser having a structure for allowing the users to train and to exercise both the upper and the lower muscle groups. [0003] 2. Description of the Prior Art [0004] Typical exercisers have been developed and provided for training and exercising both the upper and the lower muscle groups of the users, and comprise a pair of crank supported foot pedals for being pedaled by the users, and a pair of handles for being pulled or pushed by the users. [0005] For example, U.S. Pat. No. 5,114,391 to Pitzen et al. discloses one of the typical upper and lower body exercisers also comprising a pair of crank supported foot pedals and a pair of handles for being operated or exercised by the users, to conduct two actions each incorporating a mechanical movement converting output of the user to rotational motion and thereby powering one of two electrical generators. The loads are coupled by the mechanical movements back to the user to provide resistance to the exercise effort. However, a complicated chain-and-sprocket coupling mechanism is required to couple the members or elements together, and the chain may have a good chance to be disengaged from the sprockets inadvertently, and the chain may not be easily reached by the users because the chain and the sprockets are deeply engaged within the exerciser. [0006] U.S. Pat. No. 5,992,253 to Petersen discloses another typical upper and lower body exerciser comprising a shaft rotatably supported on a frame, two one-way clutches mounted on the shaft, and two pinions mounted on the one-way clutches respectively, and two bearing mechanisms and two racks mounted on the shaft and mounted between the pinions, for driving the shaft. However, the coupling between the one-way clutches and the pinions and the bearing mechanisms and the racks is complicated and may also greatly increase the manufacturing cost for the exerciser. [0007] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional upper and lower body exercisers. SUMMARY OF THE INVENTION [0008] The primary objective of the present invention is to provide an upper and lower body exerciser including a structure for allowing the users to train and to exercise both the upper and the lower muscle groups. [0009] In accordance with one aspect of the invention, there is provided an exerciser comprising a base including a shaft supported thereon, a seat cushion supported on the base, for supporting a user thereon, two foot pedals rotatably attached to the base with cranks and a spindle, for being pedaled by the user, a first idle wheel rotatably supported on the base and coupled to the spindle, for being driven by the spindle, a first generator coupled to the spindle, for being driven by the spindle, a first magnetic brake device disposed beside the first idle wheel, for braking the first idle wheel, two handles rotatably attached to the shaft, for allowing the handles to be pushed and pulled by the user, a second idle wheel rotatably supported on the base, a second generator supported on the base, a second magnetic brake device disposed beside the second idle wheel, for braking the second idle wheel, and a coupling device for coupling the shaft to the second idle wheel and the second generator, to drive the second idle wheel and the second generator. [0010] The coupling device includes two sector gears attached to the handles, and arranged to be rotated relative to the shaft by the handles respectively, a first pivot pin rotatably supported on the base, two first gears and two first pinions secured on the first pivot pin and rotated in concert with the first pivot pin, the first pinions being engaged with the sector gears respectively, a second pivot pin rotatably supported on the base and coupled to the second idle wheel and the second generator, for allowing the second idle wheel and the second generator to be rotated and driven by the second pivot pin, two second gears rotatably attached onto the second pivot pin with unidirectional bearings respectively, for allowing the second gears to be rotated unidirectionally relative to the pivot pin respectively, the second gears being meshed with the first gears respectively, and two second pinions rotatably attached onto the second pivot pin with unidirectional bearings respectively, for allowing the second pinions to be rotated unidirectionally relative to the pivot pin respectively, the second pinions are meshed with the sector gears respectively, the second idle wheel is rotated and driven continuously by the second pivot pin, via the second gears and the second pinions respectively, when the handles are pushed and pulled in reciprocating action by the user. [0011] The second pivot pin includes a pulley secured thereon and coupled to the second idle wheel, for allowing the second idle wheel to be rotated and driven by the pulley. The second idle wheel is rotatably attached to the base with an axle, and the axle is coupled to the pulley with a belt. The second idle wheel includes a second pulley secured thereto and coupled to the second electric generator, to cause the second electric generator to generate electric energy. [0012] The spindle includes a pulley secured thereon, and the first idle wheel is rotatably supported on the base and coupled to the pulley, for allowing the first idle wheel to be rotated and driven by the spindle via the pulley. The first idle wheel is rotatably attached to the base with an axle, and the axle is coupled to the pulley with a belt. The first idle wheel includes a second pulley secured thereto and coupled to the first generator, to cause the first generator to generate electric energy.
