The first is the back muscles. Back muscles are the key to a good figure. Our back contains many muscles, including latissimus dorsi and trapezius. If you have problems such as shoulder slip, you can improve your shoulder shape by exercising your back muscles. The muscles in the back can lift our shoulders and relieve the pressure on the back to some extent. Strong back muscles can protect our spine, so we can't slack off when doing back training.

Which part of the muscle can make people stand tall and straight?

Second, pectoralis major. Pectoralis major is the key to improve posture. We can exercise pectoralis major by sitting and pushing chest. The gym has special fitness equipment. We can adjust the seat to a suitable height first, then sit on the seat and hold the push handle in front with both hands. In the process of doing this, the height of the push handle should be kept at the same height as the upper edge of the chest, and the weight should be adjusted after adjusting the sitting posture.

Third, keep standing consciously in peacetime. Sometimes if you want to improve your posture temperament, you don't have to have developed muscles, but you can also improve your overall temperament by improving your standing habits. When we stand, we can consciously keep our posture and develop good standing habits, and our posture will get better and better.
