I love this bra! It's comfortable and it actually makes running so much more comfortable. I work out almost daily doing weights and running, sometimes doing jump rope. My previous sports bras were terrible for anything involving running. I actually had to hold my chest with one arm while running because there was so much bounce in one bra it was painful, and the same amount of bounce had me popping out in another bra. Worse, other bras held be down so tightly I couldn't breathe and this bra doesn't have that problem. I'm still held down but the girls are practically cradled in this bra. They don't bounce around like their trying to whack me in the face when I'm running and I honestly didn't have to think about my chest at all while running today. This is a seriously comfortable and efficient sports bra. I love it, and I hope that you will too!
