Aug. 3 (UPI) -- She might be eight months pregnant, but Serena Williams recently showed off that she's maintaining tough workouts.
Williams is arguably the best female tennis player of all-time. On Wednesday, she posted a video to Snapchat, showing off one of her taxing training sessions.
In the short clip, she hurled a large medicine ball, bouncing it back-and-forth on the ground. She also pushed a weighted sled.
Williams, 35, won the 2017 Australian Open while two months pregnant. She then decided to take a break from the sport, which she has dominated for nearly two decades.
The 23-time Grand Slam champion is engaged to Reddit co-founder Alexis Ohanian.
Williams has already committed to coming back to resume her tennis career after giving birth.
"My baby's going to be in the stands, hopefully cheering for me," Williams told TED Talks in April.
Ohanian, 34, recently told Jimmy Kimmel Live that he thinks the couple is having a girl.
"We have our hunches," Ohanian said Tuesday. "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...If anything, it's really just reinforced how amazing and strong and powerful and awesome women are."
Williams is currently ranked No. 15 in the WTA rankings. Venus Williams is ranked No. 9 in the world.
