Difficulty: Moderately Easy
Step1
If you're large breasted, consider getting an encapsulation bra which supports the breasts better than other styles of sports bra.
Step2
If you're small busted, choose a compression sports bra which presses the breasts against the chest wall to support them.
Step3
Don't buy a sports bra online. It's important to go to the store and try on any sports bra you're considering buying. You have no way to know how a bra will feel if you buy it online or by mail.
Step4
Don't skimp on quality. It's important to get a high quality sports bra that will last. Don't choose one based only on price.
Step5
Choose a sports bra with a breathable fabric. This will help to keep you cool during your workout. A good example is a Nike's DriFit.
Step6
When you try on a sports bra at the store, do some of the exercises you normally perform at the gym. Does the bra feel comfortable? If not, don't waste your money.
Step7
Try on many sports bras before making your decision. Try on a variety of bras so you can get an idea of what a comfortable one feels like. Don't choose the first bra you try on. Selecting a good sports bra takes time.
Step8
Replace your sports bra every six months or so. They eventually lose their elasticity which can mean loss of support for your breasts.
