Back muscle exerciser

Abstract

The invention belongs to a back muscle exerciser, which comprises a C-shaped fixing clamp, wherein a metal fixing ring is arranged on the C-shaped fixing clamp, two first safety hooks are connected onto the metal fixing ring and are respectively arranged at one end of one set of elastic connecting elements and one end of another set of elastic connecting elements, second safety hooks are respectively arranged on the other ends of the two sets of elastic connecting elements, and the two second safety hooks are respectively connected with air holes formed in the two sets of upper arm fixing devices. The back muscle exerciser has the advantages that the structure is simple, the design is reasonable, the posture humpback can be effectively corrected, the muscle at the back part and the too tight chest ligament of a human body are efficiently exercised, and meanwhile, the vertebral deformation of a user can be avoided.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a back muscle exerciser capable of correcting postural hunchback, efficiently exercising human back muscles and stretching over-tight chest ligaments. Background technique [0002] In real life, the tall and straight posture of a normal person relies on the teres major, rhomboid, and latissimus dorsi muscles of the back to stretch the trunk, and at the same time, the ligaments of the chest produce an appropriate stretching force to balance the pulling force of the back muscles. The back is naturally straightened. [0003] But for most people's hunchback, it is caused by the relaxation and weakness of the back muscles due to long-term bad posture, and at the same time, the ligaments in the front of the chest are tightened. The relaxation of the back muscles leads to the inability to stretch the trunk. Therefore, only by strengthening the back muscles and eff...

AI Technical Summary

Problems solved by technology

[0006] At present, the products and devices for correcting human hunchback on the market passively correct hunchback through external force devices that are forcibly applied to the human body. From the analysis of human bone anatomy, these products forcefully exert backward pull on the human body’s back. At the same time, it will also produce undue extrusion pressure on the spine, and long-term use will directly lead to deformation of the spine

At the same time, during use, due to the external force exerted on the body, the user is forcibly restrained, which forcibly limits the range of voluntary activities of the user's body, making it fail to correct the hunchback, and seriously deforming the user's spine.
