Description

A stretcher for physical fitness

technical field

The invention belongs to the field of fitness equipment, in particular to a stretcher for physical fitness.

Background technique

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 build the perfect body, and modern people love 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 contacting the equipment, and effectively improve the muscle building effect. Whether it is aerobic jogging or before performing equipment and strength training, it is best to do some stretching exercises. However, the current stretching training is often that bodybuilders stretch with their own hands through their own actions, and their own stretching effect is poor, especially The stretching of large muscle groups such as chest muscles is difficult to effectively stretch without the help of others. Chest muscles and abdominal muscles are the two muscles that bodybuilders prefer to exercise. However, most of the traditional fitness equipment can only perform some of them. It is difficult to combine the training of two parts of muscles into one equipment. Traditional fitness equipment often requires weights such as barbell plates. Users need to replace the weights to adjust the resistance of the equipment. The weights are heavier. It is easy to be injured when replacing, so it is necessary to design a safer equipment that can combine the training of pectoral and abdominal muscles and the stretching exercise of pectoral muscles and does not require weights.
