1. An exercise equipment, comprising:
two or more weight plates each having a through slot;
a weight bar having two end portions each having an outer surface and a free end, wherein each of said two end portions is sized and shaped to fittingly and slidably penetrate through said through slots of said two or more weight plates to couple said two or more weight plates at said two end portions of said weight bar respectively; and
two weight bar stoppers built-in at said two end portions of said weight bar respectively to increase a peripheral size of said weight bar at said two end portions to block said two or more weight plates being slid out of said two free ends of said two end portions of said weight bar, wherein when said two weight bar stoppers are actuated to adjust said peripheral size of said weight bar back to an original size thereof, said plurality of weight plates are allowed to be slid in and out said two end portions of said weight bar, wherein each of said weight bar stoppers has one or more receiving cavities spacedly provided on said weight bar and comprises one or more stopper members movably received in said one or more receiving cavities respectively, wherein when each of said one or more stopper members is received in said corresponding receiving cavity, each of said one or more stopper members is aligned with said outer surface of said corresponding end portion of said weigh bar to hide said stopper member, wherein when each said one or more stopper members is moved out of said corresponding receiving cavity, each of said one or more stopper members is radially moved out of said corresponding receiving cavity and protruded from said outer surface of said corresponding end portion of said weight bar to block said two or more weight plates being slid at said two end portions of said weight bar respectively, wherein each of said one or more stopper members coupled at said weight bar has a triangular shape defining a guiding surface and a blocking surface, such that when each of said one or more stopper members is received in said receiving cavity correspondingly, said guiding surface of said stopper member is aligned with said outer surface of said end portion of said weigh bar correspondingly to hide said blocking surface of said stopper member, and when said one or more stopper members are moved out of said one or more receiving cavities, said blocking surfaces of said one or more stopper members are protruded from said outer surface of said weight bar to block said plurality of weight plates being slid at said two end portions of said weight bar respectively.
