Brittany Mahomes is staying fit!

On Monday, Oct. 21, the former soccer player and Kansas City Current co-owner, 29, reposted a video on her Instagram Stories of herself working out.

In the clip, shared by fitness trainer Kirsty Rae, Brittany — who is expecting her third baby with husband Patrick Mahomes — performs a glute kickback in the gym using a cable machine.

The soon-to-be mother of three wore an all-in-one fit as she pulled her hair back into a ponytail.

Brittany, who shares daughter Sterling Skye, 3, and son Bronze, who turns 2 in November, with her Kansas City Chiefs quarterback husband, 29, also shared snaps of herself at her man’s football game on Sunday.

The game saw the Chiefs win 28-18 against the San Francisco 49ers.

Displaying her baby bump, Brittany wore a figure hugging black outfit under a custom denim jacket, which featured “Mahomes” written on the center back.

Patrick’s jersey number 15 was also written at the bottom of the jacket.

“6-0 BABYYYYYY🔥,” Brittany wrote in her caption as she shared pictures of herself posing by the field at Levi’s Stadium in Santa Clara, Calif, as well as shots of herself hugging and kissing Patrick.

Meanwhile, the proud mom also posted shots of her children on Saturday as they watched the Kansas City Current’s game against the San Diego Wave.

“Saturdays are for my babies❤️,” her caption read as she shared photos of and her kids in their box at CPKC Stadium in Missouri as they watched the game, which saw the Current beat the Wave 4-1.
