The invention belongs to the field of sports devices, and relates to a dual-seat-plate type training device capable of adjusting and controlling degrees of splits. The dual-seat-plate type training device capable of adjusting and controlling the degrees of the splits is mainly composed of two long pull rods, four stand columns, two short pull rods, two shafts, four rollers, a front plate, a rear plate, a support, a center shaft, nuts, a lead screw and other components. When the training device is used, before exercise, the upper side included angle of the front plate and the rear plate is enabled to be more than 180 degrees so as to achieve warming up, and during the exercise, the upper side included angle of the front plate and the rear plate is enabled to be equal to or smaller than 180 degrees so as to meet the requirements for exercise for various degrees of the splits. The dual-seat-plate type training device capable of adjusting and controlling the degrees of the splits has the advantages that the front plate and the rear plate can move in an up-and-down mode, arbitrary control of the splits from beginning to the various degrees can be achieved, when the training device is used, two legs of a person are located in the state that the included angle of the two legs of the person is close to 180 degrees or equal to 180 degrees or smaller than 180 degrees, the front plate and the rear plate support the weight of the person, an exerciser can insist on the splits for a longer time, and an excising effect is better.
Description
technical field [0001] The invention belongs to the field of sports equipment, and relates to a double-plank type exerciser with adjustable leg splitting degree.
