I have big boobs and I take HIIT classes and it can be painful...I would normally wear 2 bras in order to do the class without holding back. I struggle gong sport bras that fit and don't make my boobs sore from all the compression. I saw an article and this was one of the recommended bras for big boobs. I LOVE it!! I wish I could wear the cute strapping sport bras that are so in right now but my girls need support and this sport bras provides it while still being cute!!
