Actress Jessica Biel sets the standard for sexy, defined arms. Although you may not have the money or star-powered personal trainers she does, you can still achieve the same sleek shoulders, biceps, and triceps. A great way to get strong arms is through full-body exercises that target those areas, says Jennifer Devilliers, a certified personal trainer and co-founder of ThePrimeMethod.com. "Total-body exercises give you more bang for your buck because you burn more calories and see more muscle tone." Say goodbye to noodle arms once and for all with this Devilliers-designed workout routine.
