Your breasts naturally become less perky as you age, when the skin
covering them begins to lose elasticity and the breast tissue succumbs
to gravity. Pregnancy, hormonal changes, and fluctuations in body weight
also affect the shape, size and perkiness of your breasts.
1.Exercises: Exercising is one of the best ways to correct a saggy bustline and repair connective tissue and muscles around the breasts. According to Search Home Remedy, these exercises are among the most effective:
Chest Press. Lie flat on your back with a dumbbell in each hand. Extend your arms up and hold for 10 seconds. This simple exercise works the pectoral muscles. Over time, the breasts will begin to firm and reshape.
Arm Raise. To engage your chest muscles, do a simple arm raise. Think of this move as an extended stretch. Simply stand with your feet apart and reach straight up.
