Stretching device for physical exercise

Abstract

A stretching device for physical exercise comprises a base, wherein a seat board is fixedly mounted to the upper part of the base through a support; a backboard is mounted at the upper part of the left end of the seat board; a transverse rod is fixedly mounted at the upper part of the backboard through a support; hinging rods are symmetrically arranged at the front side and the rear side of the middle position of the transverse rod; one end of each hinging rod is hinged with the side part of the transverse rod; the left side of the middle position of each hinging rod is hinged with the side part of the left end of the transverse rod through a first cylinder; pushing plates are symmetrically arranged at the right of the front side and the rear side of the upper end of the backboard; the upper end of each pushing plate and the other end of the corresponding hinging rod are fixedly connected through a connecting frame; the right end of the seat board is hinged with the left end of a thighboard; a leg limiting device is arranged at the upper part of the thigh board; and a transverse lever is arranged at the lower part of the thigh board. The device is simple and ingenious in structure; the stretching effect and the body building efficiency of an exercising people can be improved by ingenious linkage.

Description

Technical field [0001] The invention belongs to the field of fitness equipment, in particular to a stretcher for sports and fitness. Background technique [0002] Fitness is roughly divided into equipment exercise and non-equipment exercise. Fitness is also a form of exercise that many men and women use to shape their perfect body. Modern people like this sport. When exercising, it is best to combine strength training and stretching exercises. The purpose of this is to stretch the muscles, avoid straining the muscles when touching the equipment, and effectively improve the muscle gain effect. Whether it’s aerobic jogging or before performing equipment or strength training, it is best to do some stretching exercises. However, current stretching training is often done by bodybuilders doing exercises by themselves. The effect of self-stretching is poor, especially The stretching of large muscle groups such as the chest muscles is difficult to achieve effective stretching without t...

Problems solved by technology

Whether it is aerobic jogging or before equipment and strength training, it is best to do some stretching exercises. However, the current stretching training is often done by the bodybuilder by doing their own movements. The stretching effect is poor, especially The stretching of large muscle groups such as the pectoral muscles is difficult to achieve effective stretching without the help of others. The pectoral muscles and abdominal muscles are two parts of the muscles that bodybuilders prefer to exercise. However, most traditional fitness equipment can only be used for part of them. Training alone, it is difficult to combine the training of two parts of the muscles into one equipment. Traditional fitness equipment often requires counterweights such as barbell plates. Users need to replace the counterweights to adjust the resistance of the equipment. The counterweights are heavier. It is easy to be injured when changing, so it is necessary to design a safer device that can combine the training of chest muscles and abdominal muscles and the stretching exercise of chest muscles without the need for weights
