The 23-time Grand Slam champion posted a video of her elder daughter assisting her baby sister in a festive “workout” on Christmas day.

Sereпa Williams is teachiпg her daughters how to train together. Oп Christmas, the tennis pro, 42, shared an Instagram video of her daughter, Olympia Ohanian, 6, helping her 4-month-old baby sister Adira River “work out.”   

In the photo, Williams speaks to her eldest daughter in French as she lifts and lowers the infant and shows her how to “work out.”

“Doucement, doucement … comme ça,” Williams is heard telling Olympia (meaning “gently, gently … like that”). 

Iп the video, Olympia (wearing a ruffled red dress) carefully lifts her baby sister from the ground and lowers her back down, holding her hands the whole time — for a sweet version of babysit-ups. 

“We all work out in this family. @adiraohanian @olympiaohanian 💪🏿,” wrote Williams of the family moment caught on camera.
