WHY ARE SPORTS BRAS IMPORTANT?Physical activity makes breasts bounce up, down and even in a figure eight. Continuous and repetitive movements can result in soreness, pain and sagging.Sports bras are made to reduce this movement. Breasts have no muscle, yet without proper support, the skin and Cooper’s ligaments (ligaments near the breast which give them their size and shape) can break down and cause sagging. Once your Cooper’s ligaments stretch out, they do not bounce back.It doesn’t matter what size breasts you have, everyone experiences bouncing during physical activity.
