Brittany Mahomes Shows Off Her Baby Bump With Third Trimester Workout: ‘Feeling Very Pregnant’

Brittany Mahomes continues to hit the gym in the third trimester of her pregnancy.

Brittany, 29, shared her workout routine via Instagram Stories on Monday, December 16, showing off her baby bump in a video where she lifts weights and does squats and lunges. She sported a lavender set by Vitality and white sneakers with her long, blonde hair pulled back into an easy ponytail. 

The clip was first posted by Brittany’s trainer, Kirsty Rae, who captioned it: “Third trimester is my fave stage of pregnancy when it comes to training. there’s studies that show your body basically goes into superhuman mode to prepare for childbirth. so badass.”

In another video, Brittany tilts her head to the side as she snaps a selfie during a break. “Feeling very pregnant,” she wrote in a caption, adding a laughing emoji. 

Earlier this month, the wife of Kansas City Chiefs quarterback Patrick Mahomes posted footage of herself working out in a cheetah print one-piece. 

“We workin,” Brittany wrote on December 3, referencing Rae.

She and Patrick announced in July that they were gearing up to welcome baby No. 3. “Round three, here we come,” the couple announced in an Instagram post at the time.

The pair tied the knot in March 2022, two years after he proposed. They are already parents to daughter Sterling, 3, and son Bronze, 2, both of whom appeared in Brittany and Patrick’s pregnancy announcement.

Brittany has been showing off her maternity fashion while supporting her husband at Chiefs games, and with Rae’s encouragement, has offered an inside look at her prepartum workouts via social media.

“Many women experience what’s called ‘mom butt’ during and after pregnancy, which happens when the glutes lose shape and muscle mass,” Rae explained via Instagram in late October. “This is often due to changes in posture and how we move as our bodies adjust to pregnancy.”

In the accompanying video, Brittany could be seen working out to avoid this particular phenomenon.

“By focusing on glute engagement and maintaining strength training, you can actually continue to build muscle,” the trainer added. “It’s all about proper movement, posture, and progressive overload.”

The day before posting her latest fitness regimen, Brittany stepped out on the sidelines of Patrick’s latest away game against the Cleveland Browns on Sunday, December 15. She paired a beige puffy jacket, emblazoned with “Chiefs,” with fuzzy earmuffs from Prada. 

Ahead of kickoff, Brittany made sure to spend time with Patrick on the field, and they shared a sweet sideline kiss.

“He doesn’t get nervous or stressed at all. That’s just what he likes to do,” Brittany said during an August appearance on the “WHOOP” podcast, noting that she gets more anxious about the games. “I think he loves going into a new week having new game plans, having new challenges, having new people that he’s playing.”
