Description

A seated pulling fitness equipment

technical field

The invention relates to the technical field of fitness equipment, in particular to a sitting type pulling fitness equipment.

Background technique

With the improvement of living standards, more and more people begin to pay attention to physical health and body shape. It has become a consensus that fitness can maintain a healthy body and a good body. When it comes to fitness, many people think of going to the gym. There are various fitness equipment in the gym, which can target different muscle groups on the body for the purpose of exercising. But in the fast-paced life, going to the gym is affected by many factors. First of all, going to the gym must take a certain amount of time, plus the previous preparations and the time spent on the road, occupying most of people's spare time Time, it is difficult for bodybuilders to persist. Secondly, the environment of the gym is poor. Multiple treadmills and other equipment will generate a lot of dust during the operation. There are many crowds, and the oxygen content in the air is insufficient. Sometimes there may be insufficient equipment. In addition, going to the gym for fitness also requires a certain economic cost, which is one of the reasons why some people give up fitness.

At present, people gradually start to consider using home fitness equipment for fitness, but home fitness equipment has not really become popular. The reason is that the existing home fitness equipment generally has a single fitness function, and a single fitness equipment can only exercise a small part of the muscle group.
