Jessie James Decker lifted some impressive weight while joining husband Eric Decker for a workout Wednesday morning.

The former NFL player posted a video of the country singer and Kittenish designer in the gym in a headband and her “sleeping socks” calling her his “workout partner” as she did some weight lifting. The mother-of-three even impressed herself when she realized she was deadlifting 150 pounds.

“Nice, babe,” Eric encouraged her, while Jessie exclaimed, “I just want a big butt!”

Her workout comes on the heels of her appearance at Paraiso Miami Beach Swim Week, where the 34-year-old made an appearance on the Kittenish runway in a peach bikini. Eric watched from the front row with the couple’s daughter Vivianne and cheered his wife on with an Instagram post.

“What a night!! Proud of this hot mama for crushing her first swim fashion show! Smoke show,” he wrote alongside a photo and video of Jessie’s runway walk.

Jessie also took to social media to share how nervous she had been about stepping in front of the audience in her swimwear.

“All the girls made me feel so confident!” she said of the other Kittenish models. “That’s what its [sic] all about.”

Jessie also spoke with Yahoo Life backstage at the show where she talked about her mission of inclusivity and how she looks to her 8-year-old daughter for inspiration for the fashion that she creates.

“Vivi influences me every single day in every way. I probably trust my 8-year-old’s opinion more than anybody in this world,” Jessie said. “I think what I teach Vivi is everyone is beautiful in their own way, in their own special unique way.”
