Serena Williams stars in a new Gatorade commercial called "Sisters in Sweat," in which she extols to her months-old daughter the value that playing sports adds to a girl's life.

"Just like it taught me, sports will teach you to be strong," Williams says. "You'll discover the power and grace of your body. You'll learn to move, and you'll learn the way to move others."

"You'll find the courage to stand tall, work harder and speak louder on whatever playing field you choose in life," she says. "So keep playing, my girl. Keep playing."

The ad features five other successful women, including businesswoman Tory Burch.

While Gatorade told *Ad Age* that the baby in the commercial isn't the actual Alexis Olympia Ohanian Jr., you can find the original on Instagram, where she has a verified account and 140,000 followers.
