Serena Williams has always been open about the work it takes to compete at the highest level. Now retired from tennis, the 23-time Grand Slam champion is sharing a different kind of performance update — this one focused on her health.
Over the weekend, Williams posted a set of photos on Instagram showing herself in a tailored skirt suit and white tank, captioning the moment simply: “That good-good… day.” The images followed a recent partnership post tied to a GLP-1 medication, where she explained that the prescription has played a role in noticeable changes to her body and lab results over the past year.

According to Williams, the results have been measurable. She said she has lost roughly 30 pounds and has seen improvements beyond the scale.
“I never thought I’d be sharing this on camera,” Williams said in a video, before revealing updated health numbers. “Some of my health stats are even better than when I was playing tennis.”
She pointed to specific markers, noting that her projected lifetime risk for cardiovascular disease has decreased by 19 percent and that her total cholesterol numbers have improved by 30 percent since starting the medication.
For Williams, the shift has been about overall wellness rather than appearance. In a recent interview, she described the change in simple terms: “I feel healthier. I feel lighter. I feel great. It’s a really good feeling.”
GLP-1 medications, which are commonly prescribed for diabetes and increasingly used for weight management, have sparked debate across sports and fitness circles. Williams acknowledged the conversation but said she hopes being transparent can help reduce misconceptions.
“I just wanted to naturally share my story and tell everyone that it’s not a shortcut,” she said to People. “It had such a stigma and I wanted to be a part of breaking that down.”

She added that people have approached her in public to say her openness influenced their own decisions. “I started GLP-1s because of you,” one person told her, a moment that Williams said showed the broader impact of speaking out.
