Knix Active with Ashley Graham Catalyst Sports Bra As someone with a 42G chest who has owned five of these bras at the same time, I can wholeheartedly say that the Catalyst Sports Bra ($89) is one worth trying. They've held my chest during HIIT workouts and when I'm just running downstairs. Image Source: knix.com Catalyst Sports Bra $89 from knix.com Buy Now
