Serena Williams flexes her toned biceps and rock-hard abs after Australian Open loss

Serena Williams looks stunning as she flaunts her slim figure in a mirror pic, after her loss at the Australian Open. The working mom recently debuted a new ad with Bumble, encouraging girls to take the first move in all aspects of their lives.

Serena Williams looks amazing in the most recent photo shared to her Instagram. The tennis superstar took a full mirror pic flaunting her toned abs and biceps in her workout gear: a white bralette from her clothing line Serena, black leggings that hugged her defined thighs, and white sneakers.

The mom of one only used a flexed bicep emoji on her caption, and fans filled the comment section gushing about her incredible figure.

“Goals...You’re looking marvelous, as always,” wrote one fan. And another added, “Power woman, you’re an inspiration.”

Two weeks ago, Williams was ousted from the Australian Open after she lost 6-4, 4-6, 7-5 in the quarterfinals against the Czech Karolina Pliskova. She was hoping to replicate her win from the last time she attended the Australian Open, but it’s been only ten months since she returned to the tennis court after her maternity leave.

Williams, always positive, says that she’s amazed by what she has done in that time, describing it as “really miraculous.” “Everything that I’ve done in 10 months has already been crazy,” she said. “It’s still little lessons that I’m learning, and I’m happy for those lessons.”

The 37-year-old welcomed daughter Alexis Olympia in September 2017, and ever since she has shifted her priorities.

Now, the 1-year-old girl is at the top of her list, and Serena is constantly seeking reassurance from other working parents online, making sure she’s not only one feeling guilty for not spending every single moment with her little one.

“I feel overwhelmed with guilt if I want to take “Serena” time. As a working mom, I feel like my “extra” time should be spent with my daughter,” she wrote in a heartfelt Instagram post. And continued:

“I have been told a million times (and even by you all) to take care of myself, so I can take care of my child. I hear it, but it’s harder to put into practice as a first time mom. Do any of you ever experience mom guilt? ”

And despite her struggles to balance motherhood and her professional career, Williams keeps shining in the industry and leading by example.

Just last weekend, a new ad featuring the 23-times Grand Slam winner was released by the dating/friendship app Bumble, and the message is one Serena wants to share with her daughter and other girls: it’s okay to make the first move.

On a recent visit to “Good Morning America,” ahead of the Super Bowl where the ad was first shown, Williams explained why the campaign, titled “The Ball is in Her Court,” resonated with her:

“I literally made the first move. My dad said I was too young and I was so small and I wasn't ready but I knew I was ready and I made that first move, and I want my daughter to be able to do the same thing.”

Williams stated that society has taught women they have to wait for an invitation and always be second, but that’s not true, and she will instill that to baby Olympia.

“I want to teach her that it’s okay to make the first move,” she said. “It’s okay to ask and to say, ‘Listen, I want a chance at being in this play. Put me in, or give me this first opportunity.’”
