Abstract

The invention relates to a back bending device for dance training, which comprises a base, lifting supports and a waist supporting plate, the waist supporting plate is of an arc-shaped structure, a connecting beam is arranged in the axial direction of the inner arc of the waist supporting plate, and the connecting beam is arranged on the base through the two lifting supports; a foot limiting framefor limiting the feet and a back supporting frame for supporting the back are arranged on the lifting bracket; through cooperation of the base, the lifting support, the waist supporting plate and thesteel wire rope, the height and the shape of the waist supporting plate are adjusted so as to meet the requirements of different people, and meanwhile, under the action of the foot limiting frame andthe back supporting frame, the problem that auxiliary supporting is needed when the people bend the waist and get up after bending the waist is solved; and the waist of a person is prevented from being accidentally injured and the use safety is improved.

Description

technical field [0001] The invention relates to a dance training auxiliary device, in particular to a lower back device for dance training. Background technique [0002] The lower back is an important training item in sports dance training. Through the lower back, the flexibility of the dancer's waist can be trained, so as to maintain the correct and graceful dancing posture. The lower back training is very difficult.
