Natalie Joy and Nick Viall attend the 2021 MTV Movie & TV Awards: UNSCRIPTED

Nick Viallis hoping his time onSpecial Forces: World’s Toughest Testwill help him become a better parent.

“They’re all great men and guys who have great character,” Viall tells PEOPLE of Rudy Reyes, Jason “Foxy” Fox, Mark “Billy” Billingham and Jovon “Q” Quarles. “We can talk about parenting tips, but I think they all taught us aspects of life and facing challenges.”

“These guys have looked to death in the face multiple times, and they’re literal heroes and warriors. And if I can teach my child to have some of the characteristics that they have, I’ll be glad I did.”

“It was really new,” Viall says of Joy’s pregnancy. “And it was a bit nerve-wracking just because Natalie had just started morning sickness, or for her, it was more like all-day sickness. So I felt pretty guilty about that.”

“We had our first doctor’s appointment coming up, so it was hard to be away from her. And thankfully, I had her support and I knew that she really wanted me to do well.”

Although Viall knew he could count on Joy’s support back home, he says it actually complicated his feelings about the show.

“But there were moments where it almost made it harder,” he says. “When you got to your breaking point, you started thinking of reasons of why it was okay to quit. It’s like, ‘I don’t need to be here.’ And for me it was like, ‘Well, I need to be home and I need to be at the doctor’s appointment,’ and things like that.”

“I just kept thinking about Natalie, and I knew I had her support. I knew that she wanted me to do well, and these guys kept me going,” Viall continues, referring to friendsJoJo Siwaand Tyler Cameron.

“But it was definitely a challenge, but at the same time, I just kept thinking like, ‘Someday my daughter,’ I didn’t know the gender at that point, I just kept thinking like, ‘Someday my child’s going to be able to watch this, and I want to make them proud.'”

“And that definitely helped me get through it as well.”
