Even the fittest women get sensitive about the annoying bulge that peeks out of the sides of a bra, through the sleeve of a tank top, or over the neckline of a strapless dress. But if you want to feel more confident in any armpit-bearing outfit, perform the exercises below, designed and demonstrated by certified fitness trainer, health coach, and fitness model Elizabeth Bracero, to tighten up your chest and shoulders. To see results, work up to four sets of 12 reps of each exercise, and tack a few of them onto your regular strength-training routine. Or, complete the entire routine in the order below a few times a week.
