“To make your breast firmer, it’s essential to invest in a good sports bra for exercising in to stop them from sagging, “ says fitness expert and personal trainer Gillian Thomas. “Try standing press-ups against a wall for toning the chest area: face a wall, place your hands shoulder-width apart on the wall. Bend and straighten the elbows to lower and lift the body back and forth.” Aim for 12 reps, three times a week. According to Debbie Missing, director of underwear company Bodas, the right bra can also make all the difference. “Smaller women should invest in a bra that pushed the breasts together. To enhance your natural shape, get measured regularly.”
