Serena Williams shows off her growing 𝚋𝚊𝚋𝚢 bump during an intense workout.

On July 4, 2023, the retired tennis star and 23-time Grand Slam champion posted three videos to her Instagram story of herself working out at her home gym.

For training, the four-time Olympic Gold Medalist (three in women’s doubles and one in women’s singles), wears a black sports bra, black cycling shorts, a pair of white boots and a pair of multicolored running shoes from longtime sponsor Nike.

Williams had her long hair done in braids and put her hair in a ponytail.

In the first video, Williams is seen stepping closer to the mirror to show off her growing 𝚋𝚊𝚋𝚢 bump as she explains to her nearly 17 million followers on Instagram what workouts she was planning to do.

‘Just [finished] some cardio and now I am about to go in and do some legs [exercises]. Let’s go!’ Williams said before stepping back.

The tennis legend also slapped her hand loudly on her legs while exclaiming ‘Let go!’ at the end of her first video.

The second video that Williams shared on her Instagram stories was filmed shortly after she completed her leg exercises.

In the video, Williams held onto a silver pole while she placed her iPhone against the mirror and then stepped back to begin a series of exercises where she threw a weighted medicine ball on the ground and caught it high up in the air.

After doing this a few times, Williams then took the ball and maneuvered it around and over her head and threw it onto the ground before repeating the same movements over again several times.

The medicine ball that Williams used was a yellow eight-point Rubber Medicine Ball, from CAP Barbell.

The Red Hot Chili Peppers’ hit single ‘Under the Bridge’ could be heard playing in the background of the second video.

Meanwhile, the third video, showed the 41-year-old doing some leg and core exercises on a light pink yoga mat.
