Brody Jenner Reveals What He Would Have Done Different amid “The Hills” Fame: 'At the Time, You're Just in It' (Exclusive)

Brody Jenner is showing a whole new side of himself on Special Forces: World's Toughest Test.

Speaking exclusively with PEOPLE about season 3, Jenner, 41, admits that the Fox competition series is quite different from other reality shows he’s done before like The Hills and Keeping Up with the Kardashians.

“This is definitely more real than a lot of the other series I've done in the past,” he shares, noting that The Hills and KUWTK had a lot more structure to the production. “I mean there was structure here, but a very different kind of structure. What they're putting you through mentally and physically, the last thing you are thinking about is being filmed.”

He admits that the entire experience was “kind of a blackout” moment for him as he filmed the intense training courses alongside Kayla Nicole, Cam Newton and more. “It's just a different side of me that people have never seen. Putting me through the hardest things I've ever had to do mentally and physically, you just sort of see a different side of me that's a little more real and vulnerable. I'm extremely vulnerable. I share a lot of deep stuff that I'm dealing with, and there's some therapy in there."

While Jenner is eager for fans to tune into Special Forces, he still has fond memories from his early days filming The Hills, which will celebrate its 15th anniversary of the series finale this year.

“It was a dream come true,” Jenner says of how the show changed his life at the time. “Honestly, Spencer [Pratt] and I had been working for years in reality television, trying to make it and get on a popular and hit television show. So at that time, it was really tough. I feel like nowadays it changed my life because all of a sudden we were living our dream. We were on one of the most popular show on MTV at the time. It changed my life in so many ways.”

Though he was blown away by the whirlwind success of the series, he notes there were still some things about the sudden fame that he “liked and also disliked.”

“I really value my privacy and I enjoy my privacy, and so you don't really understand fame until you have it,” he says. “Look, there's some very incredible things about fame, but there's also some very claustrophobic things about it. So there was the good and the bad. It changed my life in a lot of good ways and also not so good in some [ways], but still very appreciative of all that. It's kind of just what shapes you as a human being as you go forward in life.”

Looking back, he says there is one crucial thing he’d tell his younger self as he dealt with fame. “The piece of advice I would give myself back now at this age would be like capitalize on the opportunity,” he reveals. “At the time, you're just in it, you're living it, you're young. You don't realize what a valuable and incredible opportunity that is."

"I mean, we worked really hard to get to where we were at. Spencer and I, we did Princes of Malibu pre getting onto MTV," he continues. "So we were familiar with the reality television world and we loved it at the time, and we really wanted to be in the space. So once we were in there, we were like, ‘Hey, we made it. We're doing it. We did it.’ And my mentality wasn't really capitalized. It was more live in the moment, which by the way was a lot of fun and it was great. But I think that if I were to give myself some advice back then, it would be just to capitalize on the opportunity a little more.”

Special Forces: World's Toughest Test airs Wednesdays at 8 p.m. ET on Fox.
