This bra is very good for excercising or sports.  It will hold you in and in place.  However, it is very thick, but it doesn't seem to make me sweat like I was afraid it would.  You won't have to worry about nipple prints in your t shirt for sure.  It does minimize your bust, I am a 36DDD and with this bra on I look like a D cup.  Which is what I was going for.
