Stop torturing yourself already. And stop binding your breasts—that's not helping anyone. Are you doubling up your bras?
The best sports bra for DD breasts, or G cups or even A cups—because guess what, ALL sizes of breasts require support, ALL sizes of breasts can be damaged if they're not supported correctly—is the Knix Catalyst bra.
Maybe you love to run but can't maintain the distance anymore because it's painful. Or you love a good HIIT workout but you find that the jump squats or the jumping jacks are causing breast discomfort. And we don't blame you; that kind of discomfort is really awful, and it's doing permanent damage. Once the connective tissue of the breast is stretched, it doesn't bounce back like an elastic—it's gone for good. This type of pain can limit you from excelling at your favourite sport, or crushing your fitness goals. And getting to those places is already a trying feat; your sports bra should be the last thing standing in the way of achieving greatness.
Sports bras support your breast in two ways: constriction and encapsulation. Traditionally, they handle one task or the other—so you're either held in or your held down. But the Knix Catalyst Bra is different because it does BOTH at the same time, while keeping breast separate (so, no flattened uniboob). That's why it's the best high impact sports bra for DD cups.
"As a large chested woman myself, I have struggled to find a high impact sports bra that works," says Joanna Griffiths, the CEO of Knix. "The Catalyst is great because it reduces movement by over 76% (more than any other sports bra on the market) and yet is so comfortable you forget you have it on! This sports bra is the perfect balance of encapsulation (aka no uniboob) and compression to provide women up to a G cup with the support that they need."
The Catalyst is the best high impact sports bra for DD cups, and works for any workout, whether it's a high-impact workout, a lightweight jog, a pilates class, a Tracy Anderson or LekFit-inspired bounce-a long. It's so comfortable, you won't feel like you're bound or held back. What else? During her recent comedy special on Netflix, Ellen recently talked about removing sports bras is so difficult, that she just doesn't remove them. She joked that she was wearing more than eight under her outfit. Not the Catalyst! This one requires less effort to remove (thanks to the ergonomic design) as it takes to wave at somebody. Seriously!
You heard it from Joanna—but why not try for yourself, too?
