23. Contrast Shower
To improve the blood circulation of the chest and to strengthen and increase the elasticity of the tissues on the chest, the best medicine is a contrast cold shower. Hot water causes sagging and drying of the skin on the chest, but you need the opposite effect, so take a cold shower, dry yourself with a cold towel, and also keep your bra in the refrigerator to maintain the effect.
A contrast shower must be taken every day, alternating warm water with cold, ending with a cold jet. Thus, your chest will have strong pectoral muscles and look well-groomed and smart.
