John Krasinski on obtaining his Navy SEAL body: 'It was brutal'

From The Office’s Jim Halpert to a Navy SEAL!The star of 13 Hours: The Secret Soldiers of Benghazi’s John Krasinski showedoff his buff physique on the cover of Men’s Health magazine’s January/February2016 issue, though the swoon-worthy actor revealed it was not easy getting intoshape.

“I gotta be honest: It was brutalat times,” the 36-year-old told the magazine. “We did tons of metabolic work,dragging sleds and all this stuff I’ve seen NFL players do.”

Despite it being a challenge totransform his body, John said, “Getting stronger every day is thrilling.” Emily Blunt's husband only had four months to get into seal-ready shape, so to prepare forthe taxing role, he enlisted the help of celebrity trainer Jason Walsh.

And the training certainly paid off. John smolders on the cover of the men's magazine showing off his bulging muscles in a black tee.

As far as his favorite workout goes, Johnrevealed he enjoys bench pressing. He explained, “There’s that number you cankeep pushing. It’s almost a game instead of a workout.”

But it couldn't all be fun and games. John admitted there is one workout that he is not keen on doing: the “Bulgariansplit squat,” which involves doing a 1-legged squat with a rear foot elevated.No easy feat!

Thankfully for John, working out is easier when you have a fun playlist. The Office alum admitted his go-to workout track is “What More Can I Say” byJay Z. Well, looking at the results of the actor's workout has probably left more than one fan speechless!
