John Krasinski revealed how he got his newly bulked-up body in the January-February issue of "Men's Health" magazine.
Krasinski, 36 years old, shows off his biceps on the cover of the magazine wearing a simple V-neck shirt.
"I gotta be honest: It was brutal at times. We did tons of metabolic work, dragging sleds and all this stuff I've seen NFL players do," Krasinski said according to a report by US Magazine.
"The Office" star said he has just four months to get in shape for his role as a Navy Seal in "13 Hours: The Secret Soldiers of Benghazi."
"I think there's a part of you where you become addicted to it. I love feeling strong. You pick up your daughter with ease while everyone else makes a little grunt when they pick up their kids. I walk with better posture and a little more presence. I was more of a sit-in-the-corner guy. Now I'm a lot less of that."
Krasinski and Emily Blunt, 32 years old, are parents to Hazel, 22 months old.
John Krasinski also revealed what is his favorite topic when the "Men's Health" interviewer apologized for asking so many questions about his wife.
"It's my favorite thing to talk about."
In fact, he still remembers his first date with Blunt, when she invited him to a screening of her film "The Young Victoria" back in 2009.
"I remember watching that movie, and the entire time being like - I wonder who she's going to date after this," Krasinski sweetly reminisced.
On the next issue of the "Men's Health" magazine, Krasinski also talks about choosing new projects according to Just Jared.
"There's an attempt at a calculation. I just want to do everything I can. It feels like someone passed me the ball, and I want to do everything I can with it."
Krasinski hired Jason Walsh, celebrity trainer, to help him for the preparation. He loves his "muscle-building, fat-stripping work out plan."
"Getting stronger every day is thrilling," John Krasinski said according to Men's Health.
