Serena Williams turned up the heat in a yellow swimsuit.

Williams, 43, showed off her bikini body via Instagram on Thursday, August 21, in a neon one-piece while posing in the ocean. The tennis pro struck a pose with her hands on her hips as she gave fans a glimpse of her figure after opening up about losing 31 pounds with GLP-1 medication. Her swimsuit featured a scoop neck, spaghetti straps, a bow that tied over her chest and a small cutout.

Williams styled the look with a silk green scarf tied around her neck and round black sunglasses. She made her look even more glamorous with dainty hoop earrings.

The Olympian kept her look laid-back by going makeup-free. She parted her blonde hair down the middle and styled her mane in a voluminous ponytail.

Serena Williams is showing off her 31-pound weight loss after going on the GLP-1 medication Ro. “I feel great,” Williams, 43, told People in an interview published on Thursday, August 21. “I feel really good and healthy. I feel light physically and light mentally.” The retired tennis pro explained that she decided to try weight-loss […]

“Melanin mellow-yellow ⚠️,” Williams captioned the post. Her fans complimented her in the comments section.

“Looking great as always, Serena!!” one of her followers wrote, while a second added, “Looking GREAT QUEEN 🔥🔥🔥.” A third commented, “Congratulations on the success you had with your weight loss program!!”

Williams’ sexy snap comes moments after she opened up about her weight loss on Thursday.

“In particular, after having my second kid, I was never able to be at a healthy weight that I could be at, whether it was my joints or blood sugar levels,” she told Today. “It was just always something I suffered with, and a lot of women actually go through this.”

She added that “no matter” what workouts she did, she “could never go back to where [she] needed to be for my health.”

“I would walk for hours because they say that’s good,” she explained. “I literally was playing a professional sport. After my second kid, it just even got harder. So then I was like, ‘OK, I have to try something different.’”

Williams explained that getting on the medication wasn’t a “shortcut” to losing weight. “As an athlete and as someone that has done everything, I just couldn’t get my weight to where I needed to be at a healthy place. And, believe me, I don’t take shortcuts.”
