2, do not do weight-bearing push-ups and other actions, so that the chest muscles gradually contract without external stimulation. Just like the biceps brachii, the pectoral muscles will continue to grow under the stimulation of external forces to improve their strength and endurance, thus meeting the demand. Over time, the circumference will become bigger and the strength will become bigger. Without the stimulation of these external forces, it will naturally become smaller and smaller.
3. You can stretch the muscle fiber through stretching action and gradually reduce the height of the chest. Stretching the chest muscle by hand stretching the buttress or rod can effectively lengthen the muscle fibers of the chest muscle and reduce the height of the chest muscle. Each time it lasts for 30 seconds on one side, change hands immediately and make a 10 round trip continuously.
4, through the above efforts, reducing the height of the chest is completely achievable. Of course, at the same time, the whole body will lose weight, which is an inevitable result.
