The breasts are highly composed of fat, ducts, glands and connective tissue. Over the course of time, they can become lax and start to sag. If you are currently experiencing sagging breasts, there are several exercises you can do to lift them. Muscle beneath the breasts can be strengthened to offer you support.
Step 1
Utilize the weight of your body to do push-ups. Lie on your stomach with your hands under your shoulders and your knees on the ground. Lift your lower legs up and cross them and straighten your back by contracting your abdominals. Push your body up until your arms are fully extended, then lower yourself down toward the ground. Stop when your chest is the width of your fist away and push yourself back up.
Step 2
Adjust a bench to 45 degrees to do incline presses, suggests ExRx.net. Lie on the bench and hold dumbbells straight above you with your palms facing forward and the weights an inch apart. Slowly lower the weights down to your sides by bending your elbows. Stop when your upper arms are parallel to the floor and push them back to the starting position. Repeat for a series of reps.
