Denise Richards and Cam Newton spoke with “Extra’s” Melvin Robert about answering the call to undergo grueling military training in the third season of “Special Forces: World’s Toughest Test.”

Denise revealed she initially turned down the opportunity. She explained: “I said, ‘No, I’m not doing that…’ They kept calling… They said it was more mental than physical. You lied! No, I was scared too because I heard there were some athletes.”

She continued, “I was very nervous, even though it wasn’t about competing against anyone, but I was just intimidated because I was with a lot of athletes on the show.”

Richards also raved that Cam was an incredible help during the experience, stating, “Cam saved me on this show. I’m not kidding. He helped me a lot and even held my backpack. He and Golden (Tate) were so great about us girls helping each other because we have to wear the same thing and there are differences in height, weight and stuff.”

Cam pointed out, “The bag weighed the same.” Denise continued, “I felt like a weak link, but those guys…they helped us.” She stressed, “Really, without him I couldn’t have gotten through my time there. That’s the truth.”

Reacting to his fellow recruits calling him a teddy bear, Newton asked, “That’s what they said?” This experience really unnerved everyone.”

He also developed close friendships, saying, “Day by day you build real relationships with people.” When he sees his friends outside of the show, it’s like – oh my God – it’s like we have a bond for that Life.”

Newton shared that the hardest part was, “You could stop at any time. It was like, ‘Do I really want to do this?'”

He said every morning members of the group motivate each other and that helped him keep going. “Someone said something to me to remind me how important companionship is, how important relationships are and how important it is to know how to keep each other going,” Cam said.
