John Krasinski wowed in 2015 when he suddenly got crazy-fit for his role as a Navy SEAL in "13 Hours," and while he may not be as ripped as he was this time last year, the 36-year-old father of two is still working on his fitness.

"I've been maintaining," the actor told Wonderwall.com while discussing his sophomore directorial effort "The Hollars," which debuted on Aug. 26.

"I've been trying to stay in shape," he continued. "I'm certainly not as big as I was in '13 Hours.' That was a very specific built-up [look]. I definitely had more weight, if you will."

That may not be the case for long, though, now that Amazon has picked up "Jack Ryan," a 10-episode series featuring the onetime star of "The Office" as the titular CIA analyst and former Marine -- who's previously been portrayed by Alec Baldwin in 1990's "The Hunt for Red October," by Harrison Ford in 1992's "Patriot Games" and 1994's "Clear and Present Danger," by Ben Affleck in 2002's "The Sum of All Fears" and by Chris Pine in 2014's "Jack Ryan: Shadow Recruit."

"I'm definitely gonna work out again," John told us of how he plans to prepare for the show, which will serve as an origin story for the iconic character.

"Jack Ryan absolutely has to be a physical guy," added the actor. "He is more of an intelligence guy, which is the cool thing: We're going back to the beginning to the origin story, so he's just an analyst at the CIA. But at the same times, he's a former Marine, so I think staying healthy and staying in shape is important in military circles. It keeps you focused and better in your day-to-day job intellectually."

"So I think what I would love to do is have him be almost in shape, but not as jacked as I was in '13 Hours,'" he concluded.

It's a good thing John isn't aiming to get quite so "jacked" again considering the obstacles to his health and fitness have doubled since he and wife Emily Blunt welcomed their second child, daughter Violet, earlier this summer.

"The challenge to my health is my schedule," said John. "It's hard to stay in shape when you're running around doing press. It's hard to stay in shape when you're doing a movie. But the hardest part is that every second I'm not working, I want to be with my kids."

"So I'm starting to turn into that guy I never thought I'd be, trying to wake up before my kids to work out or I work out when they're asleep because when they're up and I'm up, I just want to be with them," he continued.

Fortunately, John will have some time to work on his motivation as "Jack Ryan" is still in pre-production.

"We're still trying to figure out our take on it -- in a good way," he told us of the upcoming Amazon series. "There's so much [history to the character] and so many things that we're trying to whittle down where we want to go with it, which is great."

"I just want to do something different, and luckily for me, we're jumping into something different immediately by giving Jack Ryan the opportunity to be told in a longer format," he continued. "The pitch to me from [Jack Ryan writer-creator] Carlton Cuse and why I got so excited was that two hours might not be the best format to tell the Jack Ryan stories because there's so much detail in the books and there's so much the character needs to figure out and problem-solve."

"So it's hopefully going to be a more specific, more fleshed-out world," he added. "That's what I'm looking forward to most."

As for filling the shoes of the A-list actors who've portrayed Jack Ryan before him (two Oscar nominees, a two-time Academy Award winner and an Emmy nominee), John had this to say: "I loved all the interpretations of [the character]. The four actors before me are no slouches. They've done incredible work in these movies -- and other movies."

We're sure John will do incredible work in this latest iteration too!
