A proper sports bra may be the ticket if you think there's a little too much bounce to your workout. Because the breast's skin and ligaments don't provide ample support during activity, repeated vigorous motion increases the chance of overstretching and permanently sagging breasts. And if you think it's just the well-endowed among us that have to worry, think again. All women, regardless of cup size, can benefit from the support provided by a good quality, proper-fitting sports bra.

Thankfully, sports bras are no longer one-size-fits-all. They're made from high-tech materials and designed to be comfortable, functional and fashionable. Here are our recommendations for choosing the sports bra:

Type cast: Sports bras come in two basic styles: compression and encapsulation.

Compression designs do exactly what you think: bind and press your breasts against your body, like a giant, snugly fitting Ace bandage. They're made from strong, elastic-blend fabrics and work best for small-to-medium-breasted women.

Encapsulation designs separate breasts into individual cups much like a tougher version of a standard bra design. They work best for larger-breasted women.

Fit: A perfectly fitting sports bra is as important as a perfectly fitting shoe. Your bra should be snug but not constricting, slightly tighter than an everyday bra. Bigger-breasted women should look for extra material under the armpit to ensure ample coverage.
