Tanks with shelf bras might be appropriate for a walk or low-impact yoga class, but for any kind of vigorous movement like running or hitting a Zumba class, that thin elastic material won't cut it. You need the support of a sports bra specifically designed to keep your girls in place. And for ladies who are well-endowed, built-in bras are downright frustrating — unless you like the feeling of bursting at the seams. To make sure you're getting the proper support, pair a sports bra with one of our favorite shelfless tanks.
