Arnold SchwarzennegerWhen it comes to big-time, blockbuster action heroes with bulging biceps and triceps, Arnold reigns supreme. He won Mr. Olympia seven times. Well known for his perfect muscular build and his not-so perfect use of the English language. He had 21-inch arms.
Lou FerrignoUnlike the special effects needed to transform Edward Norton into the Incredible Hulk in the 2008 blockbuster, all Lou Ferrigno needed was some green paint. Already a two-time Mr. Universe winner, Ferrigno's incredible physique and herculean 23-inch arms made him the obvious choice for the monster role that put him on the Hollywood map. You could see him in the film Pumping Iron and the TV show The King Of Queens. He also made a cameo appearance in I Love You, Man. Ferrigno is full blooded Italian-American.
Terry CrewsA veteran of comedy and action flicks, if Crews is not stealing scenes from his wife, he's doing it with his physical presence. He has huge 19-inch arms.
Michael Clarke DuncanGood luck finding a bigger actor. After working as a ditch digger, bouncer and personal bodyguard for a few celebrities, Duncan shifted direction and brought his 20-inch pythons to Hollywood to become a celebrity himself. He was in The Green Mile with Tom Hanks.
John CenaLike most guys with 19-inch arms, Cena first flexed his might and biceps on the gridiron before taking them to the wrestling ring to become a WWE Superstar. Cena's half Italian and half Irish.
Sylvester StalloneWeather as Rocky Balboa, John Rambo, or Barney Ross (in The Expendables 2), Sly has never been shy about showing off his 16.5-inch arms, particularly his tree-trunk-thick forearms.
The RockBefore becoming famous in Hollywood, Dwayne Johnson played football under the bright lights at the University of Miami. Soon after, he became one of the most celebrated stars to set foot in the WWE. With his shredded 19-inch cannons, It's easy to see why they call him The Rock. He's the son of an African-American father and Samoan mother.
Dolph LundgrenWhen Stallone was looking to cast his nemesis in Rocky IV, he needed someone with a good body who could act, box and most important, speak with a Russian accent. He just wasn't expecting that someone to be 6'5. However, once Lundgren packed on an extra 20 pounds of muscle and shredded his 17-inch arms, Drago was born.
Steve ReevesBest known for playing the Greek hero Hercules, Reeves flexed his colossal 19-inch arms in a host of high-action sword and sandal films where tough guys often fought to the death.
Hulk HoganAt 6'4" and 275 pounds, the dude is one intimidating physical specimen. The Hulkster combined size and definition for some mammoth, pumped up, crazy 22-inch pythons. Believe it or not, this giant man is half Italian-American like John Cena.
Mr. TKnown for his mohawk and excessive bling, the 1980s icon hit the big time as the Italian Stallion's trash-talking nemesis in Rocky III. While his boxing and acting skills may have needed a little more fine-tuning, his arms were ready for prime time. He had some huge 18-inch arms.
Vin DieselEven his name sounds like a tough and buff action hero, and his jacked arms back up the image. While he may be best known for his deep voice and clean-shaven dome, Diesel's muscular physique is another trademark that's often showcased in his action flicks. At 17 inches, his fully loaded guns get lots of airtime kicking butt on the big screen. His mother is an Italian from New York, and his father is of mixed African-American and French heritage.
Bruce LeeWhile not massive like some of the others we mentioned, Lee backed down to nobody. What he lacked in size, he made up for in strength, speed and toughness. Shredded to perfection, Lee's chiseled arms packed a whole lot of power behind each punch. Considered by many to be the best martial artist in the world, his functional strength was unparalleled as he effortlessly brought down guys twice his size.
Chris HemsworthTo wield the mighty war hammer of a thunder god, you'd better have some powerful arms. So to make sure actor Chris Hemsworth could deliver as Thor, he underwent an intense 12-week bodybuilding regimen to transform his physique. Chris has 16.5-inch cannons.
Stone ColdHe was also a famous wrestler before he was put on the Hollywood map after his role in The Longest Yard as Guard Dunham. This Texan has 19-inch arms.
Hugh JackmanThe Land Down Under has delivered a host of Hollywood tough guys with muscular physiques, and Jackman ranks right up there with the best of them. Although his arms aren't really huge, they are impressive when it comes to definition and vascularity.
Mark WhalbergMark didn't always have a muscular physique, but ever since he played in Four Brothers he has been pretty huge.
Will SmithIf you saw Smith in The Fresh Prince of Bel-Air, you'd say no. Ten years later in the movie Ali, you'd say, "Holy crap, the guy is huge!" He really stepped it up with an intensive training program that turned his small arms into massive guns.
Jean-Claude Van DammeA lot of people lost respect for him, but you don't have to be a fan-damme to appreciate the guns on the "Muscles of Brussels." Before blowing away the bad guys, Van Damme was a successful martial artist and kick boxer in Europe. He brought those skills, a Belgian accent and a set of 16.5-inch cannons to his first box office hit, Blood Sport.
Chris EvensHaving big, strong, powerful arms is a must for any Superhero-especially one standing up for the US of A. So when the call came out to defend the red, white and blue, Evans took his training to the next level to add some big-time muscle mass. When it was all said and done, he had built biceps worthy of the Captain America uniform.
No fair changing topics.
