I owned three of them and used them faithfully in the gym. The bounce is so minimal. I was using a size 6.
I just got rid of them because of I've lost a lot of weight (90 lbs!) and I'm ready to move to a smaller size.
I thought I could get away with a reg sports bra now that I was smaller, no way. Even on just the elliptical, I always hurt. So off I am to invest on a couple of new pairs of Enell. I always washed mine by hand and hung them to dry, not required but I just wanted to keep them looking great.
