Tennis star Serena Williams' daughter Alexis Olympia flexed her fists in cute new photos posted on Instagram.
While the 3-month-old Alexis is still quite a ways from showcasing her sport-star genes, she's already demonstrated natural form.
The former world number one posted the pictures of Alexis, who adorably held her fists up to the camera in a surprisingly professional-looking boxing pose.
Williams captioned the post "Dad and I hit the gym hard today."
