Active woman tell us that having a good sports bra can mean the difference between a good and bad workout.
"When you're on an elliptical machine or a treadmill and you're running, sometimes your chest is moving faster than you would like it to and it's a little painful," said Lauren Gerken, tester.
"If your breasts move while you exercise, you're very, very uncomfortable. And if you're a larger sized woman with a bigger cup it is extremely uncomfortable," said Kathleen Huddy, Good Houskeeeping Institute.
Good housekeeping tested new bras for women who have a d cup or more. They wanted to know how comfortable women felt in them and how well the bras supported the breast.
The top performer in the Good Housekeeping test was the Maia bra from moving comfort.
"This was a non-underwire bra. It had a nice, wide elastic bottom that was coated with a terrycloth finish. It had the adjustable velcro straps that also goes up to a size E," said Huddy.
Another top performer was the champion Powerback Underwire bra.
"The back is kind of a V-shaped, nice to look at, but it has had good coverage," said Lexie Helgerson, tester.
Here's a bit of trivia, sports bras were created in 1977 by an inventor named Hinda Miller. Miller is now a member of the Vermont State Senate.
