The invention discloses a dual-rod supporting training device. The dual-rod supporting training device comprises four cylinder bodies vertically arranged in sequence from left to right, wherein a piston capable of sliding up and down in each cylinder body is arranged in each cylinder body; a piston rod extending upwardly and vertically is connected onto each piston; a closed cavity for receiving a fluid is formed in a space of each cylinder body corresponding to the position below the piston; a space of each cylinder body corresponding to the position above the piston is communicated with the outside; each cavity is filled with the fluid; the bottoms of the cavities of the two cylinder bodies on the left side are communicated with each other; the bottoms of the cavities of the two cylinder bodies on the right side are communicated with each other; the tops of the piston rods of the two cylinder bodies in the middle are fixedly connected with a supporting plate; the tops of the piston rods of the cylinder bodies on the leftmost side and the rightmost side are connected with a horizontal holding rod respectively; and the two holding rods are parallel to each other. According to the invention, the people can do a dual-rod supporting action with a smaller force, so that the dual-rod supporting training device is suitable for the young, the old or the weak.
Description
technical field [0001] The invention relates to sports training equipment, in particular to a double-bar training device. Background technique [0002] Double poles are commonly found in leisure sports areas in campuses or communities. Double pole support is the most common type of double pole exercise, and is a common fitness exercise. Between the bars, then bend your arms down to bring your body down, then straighten your arms up to bring your body up, and repeat. But not everyone can do double-pole exercise, because the double-pole requires greater strength in the arms and can support the weight of the body. However, children, the elderly, women and the infirm usually cannot do pull-ups Movement where the arms cannot support the weight of the body. Contents of the invention [0003] The invention provides a double-bar training device, the main purpose of which is to overcome the shortcoming that the existing double-bar is not suitable for people with small arm strengt...
