Serena Williams rocks her baby bump during intense workout

If you thought pregnancy would slow Serena Williams down, you’re sorely mistaken.

Months after winning the Australian Open while with child, Williams, 35, hit the gym as hard as ever.

Clad in black leggings and a fitted tee clinging to her baby bump, the living tennis legend documented a workout on Snapchat.

Williams begins by slamming a medicine ball several times before moving on to a workout she dubbed “The Turtle,” in which she pushed an assembled set of bars forward.

In June and July, Williams posted videos practicing her signature swing.

Williams’ fiancé, Reddit co-founder Alexis Ohanian, revealed Tuesday that he thinks they’re expecting a girl.

“We have our hunches. She put it really well — she won the Australian Open while pregnant, and she remarked that she feels like it has to be a girl because everything that little baby went through and handled like a champ, only a woman could be strong enough to take on,” he said. “If anything, it’s really just reinforced how amazing and strong and powerful and awesome women are.”
