Breastfeeding or tennis? Serena Williams makes difficult decision

On the final episode of Being Serena, Serena Williams struggled physically after returning to full time tennis training. At the time of filming, it had only been 8 months since she gave birth to daughter , Alexis Olympia Ohanian, Jr.

Despite exercising before her return, Williams weighed 93.1 kg (205 lb). Serena's body was storing fat in order to produce milk for her daughter.

In order to get into shape, Williams' coach Patrick Mouratoglou told her, "There is no miracle. You stop breastfeeding, you do the right thing every day."

Williams is an advocate for breastfeeding, saying "Breastfeeding is an incredibly personal thing. The connection that it gives me to Olympia, it's been one of the most magical things I've ever experienced."

While Williams loved the bond breastfeeding allowed her to share with Olympia, she said she also missed certain things. She said, "The truth is I miss my body, being able to do other kinds of amazing things. I miss playing tennis. Mostly, I miss winning."

Williams wants her daughter to know her as a great champion, not just as a mother. She said, "Winning's always been the way I define myself and I want it to stay that way for a long time. Long enough for you to be able to watch me, cheer me on, and be proud of me."
