Chris Pratt isn't ashamed to work hard
for his incredible physique.
ET spoke with the 37-year-old actor at the Guardians of the Galaxy Vol. 2 press junket in Los Angeles on Tuesday, where he talked about going shirtless in the film. Pratt revealed how he got in great shape for the big moment.
"It's always good to know the day that you're going to be shirtless because you can really plan to try and peak on that day, you know what I mean?" Pratt told ET's Cameron Mathison. "I have a whole routine that I took from this guy who is, like, a bodybuilder guy, you know, like a guy who does competitions. And I also was a wrestler back in the day, where I would learn how to dehydrate myself to cut weight, but ... that was to create a low body weight, it wasn't to create an aesthetic. So, I have a routine that takes about a week and it involves dehydration coming off of carbohydrates."
Pratt also shared that he took a series of salt baths to help dehydrate and got a spray tan to look his best that day. Of course, he also worked out right before the scene.
"I'm doing push-ups, pull-ups, I have some dumbbells there and, you know, the main thing you need to lose, [is] shame," he joked. "You have to not be afraid to be like, 'Yes, I am the douche doing curls just before my scene,' so there's a hundred of you, and you're all judging me right now."
"But guess what? There's going to be millions of other people judging me at a later date who don't know this," he added. "You know, you got to be indifferent."
Guardians of the Galaxy Vol. 2 hits theaters on May 5.
Pratt also talked to ET about his wife, actress Anna Faris, and his 4-year-old son, Jack, traveling around the world with him
to do press for the highly anticipated Marvel film.
"That has been the best part of this world tour by far," he gushed. "It's nice to have your family with you because it brings you down to earth and when you leave your feet on the ground, you [realize] what it feels like to have your head in the clouds."
