Hi LauraLea,
I recently had breast reconstruction/augmentation and I was so worried I wouldn't be able to do any high-impact exercise due to the bouncing and discomfort. I heard about the Enell on a breast support website, so I just had to try it. It really works. It is VERY tight at first, but once you get it on, you quickly forget about it. Be sure to pay attention to their sizing instructions. I wear it now whenever I run and when I do hi-lo or other hi impact Cathe workouts.
If you don't feel quite ready for an Enell, there are plenty of non-bounce bras available. Take a look at Title9sports.com. They rank their bras on the barbell system - 1 meaning little support, 5 being the most support. The Enell is the only bra on there with 5 barbells and its called the "Last Resort Bar" on their website.
I hope this helps.
Joy
