"That's impossible," the supermodel told the news about working out with her NFL boyfriend.

Olivia Culpo loves a good sport, but not when she's with her NFL boyfriend, Christian McCaffrey!

"I honestly hate training with him," Culpo, 30, told the news at the Create & Cultivate LA conference, where he discussed his career. "Because he's a professional athlete. He works for a job."

The model and McCaffrey began dating in April 2019 and made their love public when they were photographed together while on vacation in Mexico in July.

Despite both being in fine form, Culpo found it challenging to keep up with his opponent, who was a first-round pick for the Carolina Panthers in 2017.

"That's impossible," said Culpo. "As the weight, he's lifting; it's pointless even to try to do anything in the realm of what he's doing." The Sports Illustrated model admits that her training consists solely of posing in a swimsuit also she wants them to stay that way.

"I was just practicing to make it in my underwear," Culpo told the news with a laugh. "It's just a different level for him, and he always wants to ensure my performances are perfect. It can get annoying [and] we'll work [together] to some degree, but he's like that, especially for training." 

"No," said Culpo when asked if he liked McCaffrey to improve his appearance. "I just tell, 'Let me do my job.' I'll do it. I'll do it yourself. You do it yourself. "But it's fun! I'd rather watch it."

The former Miss USA never misses an opportunity to cheer on McCaffrey, whom she calls "the best friend ever," and she does the same. He even surprised Culpo by appearing before taking the stage at the Create & Cultivate conference.

"He's hilarious," said Culpo. "He is very caring and wants to support."
