Strapped for time or cash? Don't sweat it: We've got your new personal trainer right here. Give Shape fitness contributor Nora Tobin seven minutes, and she'll show you how to strengthen and tone every part of your body. Decide if you want to work your abs, arms, legs, or butt (or all of them!) and follow along. Since the videos are so quick and all you need is a set of dumbbells (or your own bodyweight for many exercises), you can do these workouts anywhere and whenever you have time.
