Speaking for the average-busted woman, this bra provides great support while doing plyometrics, P90x, and running.  Comes is great colors too. I wish the color of this bra was offered on the manufacturer's website so I could get it at a reasonable cost. Oh well, I ordered similar bras at a better cost and hope they are as good as this one. I'm very happy with this sports bra, and will look to this brand in the future.
