Are sports bras really needed? And why?

YES! Sports bras are needed.

For one thing,  when you do any exercise, if your shirt flies up, nobody will see anything!

For another, If you happen to be well-endowed, a sports bra is more supportive than a regular bra for athletic movement. Most of them are also designed to "breathe" so that you're not drenched in sweat.

Sports bras can be divided into three kinds: Low impact, Medium impact and High impact.

Low-impact sports bras with comfortable detailing provide light support for yoga, Pilates or barre workouts.

Extra support in medium-impact sports bras help elevate your performance for that next gym, spin or studio class.

High-impact sports bras offer maximum support with molded cups for high-energy runs and aerobics.
