Speaking to BW Magazine, the 25-year-old model claims there were times during the show's filming where she thought the couple would not make it to the end.
She told the publication, "It was gnarly and every week got harder and harder."
"We didn't know how we'd get through it because they kept putting challenges on us," she added.
The model further claims the series was more about mental toughness than it was about physical toughness.
The model further said, "We wanted them to know we couldn't be broken. They'd try to mentally break you down, but if you had a positive mind you'd be OK."
