Austin Butler is bringing the heat to the September/October issue of Mens Health. The 34-year-old actor, best known for Elvis and Dune: Part Two, is showing off a physique so chiseled it could stop traffic.The reveal comes as Butler gears up for his latest role in Darren Aronofskys upcoming crime thriller Caught Stealing, hitting theaters Aug. 29.From Lean to Bulked UpButler underwent a striking physical transformation to play Hank Thompson, a washed-up baseball player whose life spirals into chaos. The role demanded more than just acting chops, it required serious muscle.Standing at 6 feet, Butler reportedly packed on nearly 15 kilograms, trading in his naturally lean frame for a sturdier, more athletic build. I actually have a whole section of just baseball players asses that [Aronofsky] would send me, Butler told Mens Health. He was like, Look how thick they are!The training paid off. Butler admits he no longer fits into his designer wardrobe: Ive got a whole section of Celine pants that I just cant even wear anymore.Sweat, Hip Thrusts, and Heavy LiftingTo achieve his new look, Butler worked with trainer Beth Lewis, who also trained Hugh Jackman for Wolverine. His workouts included balancing on BOSU balls, one-arm kettlebell moves, and countless hip thrusts to build power and, yes, the booty Aronofsky demanded.Butler explained that his thinner frame ahead of filming was due to awards season, when meals sometimes took a backseat to red carpets and interviews. This time, he flipped the script with calorie-dense meals and relentless gym sessions.Cheat Meals and Clean LivingWhile Butler admits to indulging in pizza, pasta, French toast, and pancakes all at the same time during bulking season, alcohol never made the cut. Drinking has never been my thing. I dont like the way it makes me feel, he said.That discipline isnt new for the actor. For Elvis, Butler famously fueled himself with ice cream and doughnuts to capture Presleys later years. For Dune: Part Two, he trained military-style with an exNavy SEAL and lived on a diet of rice, chicken, and broccoli.Hollywoods New Heavy HitterButlers upcoming film boasts a star-studded cast including Zo Kravitz, Regina King, Bad Bunny, Matt Smith and Liev Schreiber. But before audiences see him hit the big screen, his cover shoot is already cementing him as Hollywoods newest fitness icon.For now, Butlers dedication, and his transformation, have everyone talking. Whether hes lifting kettlebells or devouring stacks of pancakes, hes proving theres no role, or workout, he cant take on.Source
