Please refer to FIG. 1 to FIG. 18. FIG. 1 to FIG. 10 illustrate a first embodiment, and FIG. 11 to FIG. 18 illustrate a second embodiment. A dumbbell and barbell supporting system of the first embodiment of the present invention will be illustrated in the following paragraphs. The dumbbell and barbell supporting system includes a main support 10, two support members 20 and placement bases 30. The main support 10 has two foot parts 101 and a rod 102 connected to the two foot parts 101. An end of each of the two foot parts 101 is connected to a corresponding one of two ends of the rod 102, and another end of the each of the two foot parts 101 stands on the ground. The two support members 20 are configured to support an end of one of a dumbbell 100 and a barbell 200. The two support members 20 are mounted on two ends of the rod 102 and opposite to the two foot parts 101, respectively; each of the two support members 20 has a placement slot 201 recessed on a top thereof toward a bottom thereof, and the placement slot 201 has an opening 202 formed on a bottom thereof. A part of the rod 102 is exposed out of the opening 202. The placement bases 30 are mounted in the placement slots 201 and inserted through the openings 202 to slidably connect to the rod 102, respectively. The placement bases 30 disposed in the same support member 20 can be moved close to or away from each other along an arrangement direction of the rod 102, to perform a conversion between the dumbbell 100 and the barbell 200 for use. A weight element group 300 is movably disposed between one of the placement bases 30 and a sidewall of a placement slot 201 closest to the one of the placement bases 30.

After the operation of the dumbbell 100 is completed, a user can place the dumbbell 100 aside and control the placement bases 30 in each of the two support members 20. The support member 20 in left parts of FIG. 7 to FIG. 10 is taken as an example for illustration. After the dumbbell 100 is separated, the placement base 30 in a left-hand side of the support member 20 is controlled to move toward and get closer to the placement base 30 in a right-hand side of the support member 20; next, the user lifts the weight element group 300 in the right-hand side and turn to the weight element group 300 in a left-hand side, to combine the two weight element groups 300. After the user combines the two weight element groups 300 completely, the user lifts the barbell 200 from below to above the main support 10, and two ends of the barbell 200 are placed in the corresponding placement bases 30, respectively; next, the user adjusts the number of pieces of the weight element groups 300 to combine with the barbell 200 according to a loadable weight of the user. In the other hand, in order to convert the barbell 200 into the dumbbell 100, the user just needs to separate the placement base 30, which are closer to each other, according to above-mentioned steps.

Please refer to FIG. 2 to FIG. 5, each of the two support members 20 further includes two stop boards 203 and two stop rods 204, each of the two stop rods 204 is a strip body in an inverted-U shape, the two stop boards 203 are arranged in interval and corresponds in position to each other, and two ends of each of the two stop rods 204 are connected to the two stop boards 203, respectively. The connection between the two stop boards 203 and the two stop rods 204 form a placement slot 201 with an opening 202, each of the two stop rods 204 has a fastening part 2041, two ends of each of the placement bases 30 are engaged with the fastening parts 2041, respectively, so that two ends of each placement base 30 can be firmly engaged with the stop rod 204; furthermore, the placement bases 30 are mounted in the rod 102, so the placement bases 30 can be smoothly moved.

Each placement base 30 includes a placement groove 301 recessed on a top thereof,

two blocking parts 302, and two clamping parts 303 opposite to the placement groove, respectively. The placement groove 301 is configured to support the weight elements on two ends of the dumbbell 100 or the barbell 200, and the two blocking parts 302 are disposed on two ends of the placement base 30, and configure to engage with the fastening parts 2041, respectively. The two clamping parts 303 are protruded on bottom of the placement base 30 and slidably connected to two ends of the rod 102, respectively. Each of the two blocking parts 302 includes an abutting rib 3021 and a hooking block 3022. The abutting rib 3021 of each of the two blocking parts 302 is abutted with a surface of a corresponding fastening part 2041, and each hooking block 3022 is engaged with a distal end of the corresponding fastening part 2041, so that the abutting ribs 3021 of the two blocking parts 302 are in contact with the fastening parts 2041, the hooking blocks 3022 are engaged with bottoms of the fastening parts 2041, respectively, and this multi-direction restriction can prevent the placement base 30 from shaking during movement, as shown in FIG. 5. The rod 102 has at least one sliding rail 1021 recessed correspondingly in position to the clamping parts 303, an end of each clamping part 303 is connected to the bottom of the corresponding placement base 30, another end of each clamping part 303 is extended toward two sides of the rod 102, and the extended end of the clamping part 303 has a slider 3031 protruded thereon, the sliders 3031 are inserted into the sliding rails 1021 on two sides of the rod 102, respectively. The slider 3031 protruded on the clamping part 303 is inserted into the corresponding sliding rail 1021, so that the slider 3031 is movable along the sliding rail 1021.

The placement base includes cushions 40 disposed on the top of the rod 102 corresponding in position to the opening 202, and surfaces of the fastening parts 2041 of the two stop rods 204, respectively.
