This is not a typical under armour sports bra. Even though it says hi-support, the padding is incredibly flexible and does not really feel supportive at all. If I had even attempted running in this, I'm sure the support would be minimal. It was difficult to get on, even though I have another under armour hi-support sports bra in the same size. I do not recommend this product to anyone trying to do athletic anything while wearing it. Half of your exercise will be getting it on.
