Graham, 28, who lives in Park Slope, Brooklyn, and is "a size 14 or 16, depending on the day," stays in shape by putting up her dukes and working up a sweat. "I love boxing. I have a local gym," she said.
The model is one of three 2016 S.I. Swimsuit Issue cover girls — a first in 52 years for S.I. — along with fashion model Hailey Clauson, 20, and mixed martial artist Ronda Rousey, 29.
Graham is in an editorial feature as an S.I. "rookie" as well as an advertisement for Swimsuits for All. Like her head-turning figure that's made her a high in-demand model, Graham's attitude is well-rounded.
"It doesn't matter what size you are or how old you are," she said. "Ads tell you that you have to be thin. The word perfect goes around. It's draining."
"Do I consider myself a role model? I call myself a body activist for a reason. I'm the oldest of three girls. Girls are told 'Watch what you do, watch what you say.' My body isn't what is called perfect. I say embrace your curves."
