Serena Williams is Already Working on Her Post-Baby Tennis Comeback

Serena Williams will reportedly be back on the competitive tennis circuit at just four months postpartum. But then, was there ever any doubt? 

File this under "Further proof Serena Williams is unstoppable": The tennis star isn't taking a total break from her court game as she prepares for parenthood. Instead, she's spending her pregnancy getting ready for a return to the sport. 

Of course, we'd expect nothing less from the woman who won the Australian Open during her first trimester. Williams has said she plans to return to competition at just about four months postpartum, and she's already working to make sure she acheives her goal. 

Need proof? The tennis pro posted a video of herself preparing for the comeback. She may be seven months pregnant, but Serena still has so much energy and her tennis game is still crazy strong. She is one of the greatest tennis players of all time, of course—and pregnancy can't hold a woman down—but it's still amazing to see a preggo do what Serena does. Doesn't she just make it all look so effortless?

The tennis star is reportedly set to give birth in September 2017, and she told Vanity Fair she plans to return to the tennis world in January 2018. If this workout video is any indication, she'll be better than ever post-baby.
