Nobody wants to sag, but gravity works it's magic over time and things start to point south. Exercise has numerous benefits, more than we could list in this post, but it comes with a few catches, too. Exercise isn't always so friendly on 'the girls.' However, with a good maximum support sports bra, you get some of that worry off your chest. According to Joanna Scurr, PhD, a biomechanist at the University of Portsmouth, a high-impact sports bra can cut bounce in half. So as you jump, run, walk, lunge, spin, or whatever gets you sweating- it's going to take more than a thin cotton sports bra to give you the support you need.

Here are 5 ways to determine if you aren't wearing the best maximum support sports bra.

1. Jump Test. Jump, just once or twice. Do you feel that? If you are getting hit in your face or feel any discomfort at all, especially on the outer sides of your chest, you need more support. Now, try a jumping jack (Warning- if anyone is watching, they might be confused as to why you're doing just one of each of these moves). If you are wearing a compression bra, instead of an encapsulation bra, this may be your first mistake.

2. You are wearing more than one. You found a sports bra on the clearance rack and decided to get three, because who doesn't love a good deal? Only issue--in order to participate any kind of exercise, you have to wear all three at once. Now, you have three sets of straps digging into your shoulders. And getting those sweaty things off after a workout? That's a workout in and of itself. You're not alone - lots of women say they wear more than one bra at a time, but that doesn't make it okay.

3. Your back hurts more than your thighs after leg day. If you are well endowed, you are putting a good amount of strain on your back. If you aren't wearing a good maximum support sports bra, you aren't doing your back any favors. 56% of women experience pain that leads to ligament damage, sagging of the breasts or back and neck pain. Properly fitted straps take the weight of the breasts off of the shoulders.

4. You're soaked. Sweat is great! Burn those calories away, girl. However, if your sports bra is drenched, it is an open invite for bacteria which can lead to the dreaded 'bacne.'  Cotton is not sweat-friendly; instead, opt for fabric that is moisture wicking, cutting down on potential bacteria growth.

5. It's from your high school PE class. Just like every piece of clothing, sports bras start to show some wear over time. To extend the life of your sports bra, wash in a lingerie bag and hang dry. Even with proper care, it is necessary to restock every once in a while - most experts agree, 6 months to a year is the lifespan of a sports bra.
