Bradley Cooper’s transformation into Navy SEAL Chris Kyleremains one of Hollywood’s most dramatic physical metamorphoses. On Joe Rogan Experience #2435, Cooper detailed the intense preparation that took him from 185 pounds to 238 pounds—and confirmed he achieved it naturally.
“I went from 185 to 238,” Cooper stated. “And all naturally, because cancer’s in my family. I’ve had skin cancer and I’m terrified of anything. So I was not going to do that.”
When Rogan asked specifically about PED, Cooper’s answer was straightforward: “I took creatine. Yeah.”
The actor emphasized this was his only supplement beyond food, describing an intense six-month preparation period. “6,000 calories a day,” Cooper explained. “The first week I did it with real food and that was a big mistake because I couldn’t get up. I couldn’t move my stomach.”
He adjusted his approach, splitting the massive caloric intake between whole foods and protein shakes. His training regimen was equally demanding: “Worked out twice a day. Five. I had three rest days, no cardio. It was all about strength training and it was all focused around deadlifting.”
Cooper worked with trainer Jason Walls, structuring workouts around Monday, Tuesday, rest Wednesday, Thursday, Friday, rest Saturday, Sunday. The focus wasn’t just size but authenticity.
Beyond the gym, Cooper immersed himself in SEAL culture. He worked extensively with Kevin Lace (who played Dauber in the film) from SEAL Team 3, training at the Disney ranch with “600 yard head targets prone.” He studied three specific weapons and learned to factor in “the curve of the earth” for long-distance shots.
The transformation was as mental as physical. Cooper maintained Chris Kyle’s accent throughout filming and worked out to Kyle’s personal playlists. “I would do that and look at him every morning,” he said of training while facing enlarged posters of Kyle. “It was this beautiful ritual that I felt I was with him every day.”
Recently, Cooper revealed he’s returned to creatine supplementation, participating in a push-up challenge with other parents at his daughter’s school. “I started taking creatine two and a half months ago,” he shared. “Creatine is incredible.”
When Rogan mentioned creatine’s cognitive benefits, Cooper acknowledged hearing about them.
Ultimately, believing Cooper achieved such a dramatic transformation without the assistance of PEDs demands quite a suspension of disbelief. Joe Rogan criticized movie stars for exactly this type of behavior countless times but when push came to shove he offered no resistance to Cooper’s extraordinary claims.
