We all know that one of the main things that Hollywood usually focuses on is these hero characters with gargantuan muscles. The heroes have been, for a very long time, the ones with the most impressive muscle structure in the movies that come from the so-called silver screen. But what about the people who are really strong behind the scenes and were responsible for these roles? And what are the exact things that are necessary to be like that? Thus, it is the very first thing: with a shake of the protein ready, we are listing the 15 strongest stars in Hollywood. And the answer is yes— we are doing it backwards—just because it seems more appropriate to keep the last ones as a surprise.
15. Chris Evans
Before, Captain America, Evan was sporty, but he lacked muscles. To portray Marvel’s iconic patriotic soldier, with the help of trainer Simon Waterson, he went on to increase his mass significantly. Heavy compound lifts, bodyweight training exercises, and a strict diet were the tools that helped him gain mass fast. Evans admits that eating was harder than training; however, he says that the result – a superhero’s body that was strong yet nimble – was definitely worth the hard work.
14. Jake Gyllenhaal
Gyllenhaal’s Southpaw transformation is one of the most dramatic in Hollywood. He was a real prizefighter in training: every day, road work, thousands of sit-ups, sparring sessions, and an all-consuming work ethic. The shredded, fight-ready physique he achieved was so realistic that it heightened the performance itself. Even now, in his 40s, he continues to push himself for performances, recently putting himself back into heightened physicality for Road House.
13. Hafthor “The Mountain” Bjornsson
This one’s hardly fair—Hafthor’s not merely playing strong, he is strong. Former World’s Strongest Man and Game of Thrones actor is over two meters tall and deadlifted a record 500kg (1,104 lbs) back in the day. When he appears on screen, no special effects are required—he’s an actual giant whose strength feats make Hollywood’s fittest stars look puny.
12. Sylvester Stallone
Few actors embody “ripped action hero” like Stallone. Back in his Rocky and Rambo days, he was benching 400 lbs and squatting 500 lbs. He strained so hard that at one point he ripped his pec in a competition, requiring more than 160 stitches. Yet even at this point, long past his 70s, Sly continues to train with the intensity of a man half his age.
11. Michael B. Jordan
Whether it’s boxing with Creed or sparring with T’Challa in Black Panther, Jordan’s makeovers are on another level. For Killmonger, he allegedly had seven protein-rich meals a day while bludgeoning himself with heavy incline presses and strength circuits. The result: a deadly, fight-ready appearance that kept up with his merciless on-screen demeanor.
10. Henry Cavill
After a more slender gamer frame, Cavill reformed himself into Superman in the hands of trainer Mark Twight’s tough love. The regimen combined Olympic lifts, calisthenics, and stamina work, reducing his body fat level to under 10% and adding serious size. Cavill has stated that the training not only provided him with the physique for the cape, but also the discipline to sustain the role.
9. Jason Statham
Statham doesn’t only act tough—he lives it. His training consists of explosive, functional strength: calisthenics, martial arts, gymnastic-style holds, and combat conditioning. He’s been known to train under the guidance of military-style instructors, opting for raw, real-world power rather than bulk. If anyone appears prepared to fight a dozen bad guys simultaneously, it’s him.
8. John Cena
Before reaching Hollywood, Cena was already a top WWE star. His strength levels are mind-boggling—squatting close to 300kg, benching more than 200kg, and pulling near 300kg. Cena trains with unrelenting commitment, and his home gym is the stuff of legend among emerging athletes.
7. Mark Wahlberg
Wahlberg’s infamous daily schedule—waking before dawn, multiple workouts, endless meals—has become meme-worthy, but the results are undeniable. His 335-lb bench is no joke, but what really defines him is consistency. While others bulk and cut for roles, Wahlberg stays camera-ready year-round.
6. Hugh Jackman
Across almost two decades of portraying Wolverine, Jackman rebuilt his physique repeatedly. He became a member of the “1,000-pound club” with a total bench, squat, and deadlift of over 1,000 lbs. His prescription? Heavy compound lifts to develop strength, then high-rep finishers to remain lean. His commitment provided us with one of the cinema’s greatest physiques.
5. Jason Momoa
Momoa’s training appears less like a gym session and more like an adventure in the wilderness. Surfing, boxing, climbing, sprints—his training doesn’t just keep him strong and agile but also massive. The ability to churn out weighted pull-ups with almost 90 lbs attached is an indicator of how functional his strength is.
4. Zac Efron
Forget the High School Musical child—Efron’s Baywatch makeover was savage. He dropped down to a freakish sub-5% body fat within three months through intense functional training and calisthenics. Nowadays, he freely exposes his techniques on his YouTube series, unveiling to his fans that his body isn’t all genes—it’s a grind in its purest form.
3. Chris Hemsworth
Hemsworth’s Thor physique is perhaps the ultimate body for Hollywood. With trainer Luke Zocchi, he alternates between weightlifting, functional training, and endurance sessions—sometimes two or three per day. The most difficult thing, his stunt double says, isn’t the training but the food. It takes about 8–10 meals and 4,000 calories of food per day, which is effectively another full-time job.
2. Dwayne “The Rock” Johnson
At the age of 51, The Rock just keeps on getting bigger. His portable gym—the “Iron Paradise”—tips at 20 tonnes, and his twice-daily routine has him benching more than 400 lbs while keeping himself in action-figure shape. His commitment is unyielding, albeit his bulk has also rekindled Hollywood’s constant controversy surrounding the use of PEDs and the pressure placed upon actors to appear superhuman.
1. Arnold Schwarzenegger
At the top of our list is the original starter. Arnold isn’t an actor—he’s a symbol of power. A seven-time Mr. Olympia, record-holding lifter, and one of the first action stars, he raised the bar for all to follow. His mythical lifts (200kg bench, 310kg deadlift) and dedication to training throughout his life make him Hollywood’s original—and still greatest—strongman.
Behind every screen transformation is a brutal reality: months of gym torture, rigorous diets, championship trainers, and occasionally a bit of Hollywood smoke and mirrors. From Mark Twight’s brutal philosophies to rumors of performance enhancers, there’s more than one path to creating a blockbuster body. But one thing’s certain—strength in Hollywood isn’t for the cameras only. For these celebrities, it’s a way of life.
