Emily Blunt is a fan of the dad bod. Her husband, actor John Krasinski, told Stephen Colbert that Blunt "hates" his new beefed-up bod.

"She hates it," Krasinski said on "The Late Show." "She would prefer to have doughy guy back."

The former "Office" star transformed his body to play a CIA contractor in "13 Hours: The Secret Soldiers of Benghazi."

"I thought it would be like, 'Yeah, let's eat a couple of Power Bars and do pushups.' And [my trainer] was like, 'No. It's going to be a living hell for six to eight weeks.'"

Krasinski trained with Jason Walsh who also prepped Bradley Cooper for his "American Sniper" role.

"I was like, 'What about these bicep curls?' He was like, 'No, it's so much harder than that...you have to do 80 pushups by tomorrow.'"

Krasinski's wife is no stranger to a hard workout; Blunt trained for her roles in the action films "Edge of Tomorrow" and "Sicario."

"I watched her fight train, because we trained out in the same gym...and then she did very extreme fight training, and I walked by a door just to be like, 'Hey! How's it going?' And then she was punching and elbowing this bag that was starting to open with, like fluff in it, and all I could think was, 'Please don't have a nightmare tonight! Please don't have a nightmare tonight!'"
