Because sometimes it's nice to hit the treadmill without knocking yourself out. With great boobs comes great responsibility, so the importance of finding the perfect sports bra should never be underestimated. We’ve teamed up with the good folks at Lifestyle Sports to bring you five reasons it's vital to wear a sports bra. Check them out below! 1. Support is a beautiful thing The number one reason to invest in a decent sports bra is support. Because let's face it, a girl can only run as fast as her boobs will allow. Depending on the sport you are using it for, the correct sports bra should help to contain the amount of movement around the bust area and provide support. It will need to be closer-fitting then your regular bra, so don’t be put off if it’s a bit tighter. 2. The comfort factor With no hard underwire, no straps digging into your shoulders or hooks into your back, sports bras are a dream to wear. The breathable fabric means they generally fit like a second skin. 3. Keep them locked and loaded No matter kind of exercise you’re doing, a sports bra will help minimize the bounce factor. The size of your bust will dictate the style of bra that best works for you. Compression-style sports bras are best for small to medium-sized breasts, whereas an encapsulated-style sports bra is more like a regular bra, supporting each breast on its own. This style is ideal for larger-sized breasts. 4. Combat that river of boob sweat We're all familiar with the lovely river of between-boob sweat that comes with working out. Well, it turns out that wearing a sports bras can go a long way towards regulating the temperature of the body as you exercise. Standard bras don't absorb sweat, so perspiration will end up gathering along the material and leaking down your back. There's none of that with a sports bra. Because most of them are made from soft, cotton blends, the body doesn't sweat nearly as much when wearing a sports bra. 5. Keep everything ship shape We all want to protect and preserve our breast shape, and getting a great sports bra is the easiest way to do so when you're working out. Along with reducing the amount of movement and stretch inflicted on the ligaments, a sports bra also limits the amount of pressure put on the breast, which helps maintain breast shape. And when you finally find that perfect sports bra... this is how you'll feel. It's a glorious feeling. This article is brought to you by Life Style Sports.
