Best Fitness Regimen
1. Chris Hemsworth, Thor 2: The Dark World
If you're the Norse god of Thunder, you're probably born with bulging biceps. (Though throwing around that Mjölnir can't hurt.) To get that god-like physique, Chris Hemsworth recruited trainer Michael Knight, who put the actor through a routine of high-weight, low-rep moves combined with a total body circuit and a diet high in protein, brown rice, and veggies.
2. Henry Cavill, Man of Steel
Man of Steel's hefty prologue showed that not all native Kryptonians have abs as impressive as Kal El's. Clark Kent comes by his thanks to Earth's atmosphere and his many jobs as a drifter, which include fishing off Alaska and working on an oil rig. Henry Cavill bulked up first by eating 5,000 calories and training two hours a day, five to six days a week, for 11 months.
3. Joseph Gordon-Levitt, Don Jon
Jersey boy Don Martello is as committed to his gym routine as he is to his porn addiction. Joseph Gordon-Levitt packed on 12 pounds of muscle by going to the gym for two hours a day, every day, for six months, and cutting fat, sugar, carbs and dairy out of his diet.
4. Hugh Jackman, The Wolverine
If you're an immortal with adamantium running through his veins, it stands to reason that you're also probably going to be pretty fit. For his sixth time playing the crankiest of the X-Men, Hugh Jackman ate every two hours – chicken, steam veggies, and some carbs, for as many as 6,000 calories a day – and worked out for three hours.
5. Mark Wahlberg, Pain & Gain
To play the washed up body builders in Michael Bay's take on this incredible true story, Duane Johnson, Anthony Mackie, and Mark Wahlberg had to work, hard. Wahlberg ate 10 to 12 meals a day, drank weight gainers, and woke up at 4:30am every day for a workout that involved lots of heavy lifting.
WINNER: Pain & Gain. No actor this year was more committed to getting huge than Johnson, Mackie, and Wahlberg
